PREFACE.

>

Tus work is mainly designed to encourage junior students to take a general interest in the vegetable beings living in this State. In pursuit of this end technicalities have been reduced, descriptions and general information have been abbreviated, and economy has been studied in every part.

The system adopted is that of Hooker and Brntuam, the one that is at present in use in most English-speaking communities. Many efforts have been made in recent years to improve on this. The late Baron von MuELueER designed a system thet is at present used largely in Victoria, and partially in New South Wales and South Australia, but it is doubtful if any extensive change will be made until a scheme is presented containing such radical improvements that a prospect of reasonable permanence may be foreseen.

The main objection to Hooker and Bentuam’s system is that it contains a section—the Monochlamydeex or Incomplete—that really is a sort of dumping- ground for all forms+that have no relations elsewhere. This, of course, is not as it should be. Here we have primitive forms that have not yet acquired the typical Dicotyledonous form classified with plants of a reduced character that once possessed that form and have evolved away from it.. But the state of affairs is not improved by distributing the Incompletes haphazard amongst the rest. Students should always bear in mind that not only are the great groups of plants descended from types long since lost, but the smaller groups and Natural Orders are seldom related in direct descent, and therefore any system that undertakes to classify plants in linear succession must necessarily be arbitrary, and almost entirely erroneous. Muz.ier’s arrangement, and a more recent system by Dr. Warmine, of Copenhagen, will be found in the Appendix.

Plants, other than grasses, that have established themselves since Tasmania has been settled have only in few instances received the attention of natives, but are placed in an indented position. Had convenience permitted, their descriptions would have appeared in smaller type.

The Plates must not be looked upon as the work of the Printing Department ; they are faithful copies of the author’s drawings. Had the departmental artists been permitted to idealise them some departure from a faithful copy of nature must have resulted, besides which increased cost would have necessitated a considerable decrease in number, which may have been the reverse of desirable.

iv THE TASMANIAN FLORA.

The intersticial keys are not uniform. Those necessarily arbitrary are dichotomously arranged; where permissible more direct comparison has been adopted.

Flowering periods are more general than, particular, and local distribution

is, perhaps, all too meagre.

The synonyms included -are only those required for reference to voN Moeuuer’s works, Benruam’s “Flora Australiensis,” and Hooxer’s ‘“ Flora

Tasmaniz.”

In the Appendix will be found a Dictionary that is something more than a Glossary. Names of genera and most of those constructed from |the names of individuals have not been included. Immediately before the body of the work, appears a Key to the Natural Orders and some other groups. This is constructed purely to help those who approach the study with little or no previous experience.

The author would take this opportunity of expressing his thanks to very numerous friends who have helped him. Chiefly amongst these W. V. FirzGERAwD, who for years forwarded valuable material; T. B. Moors, for many most interesting plants; Auc. Stmson, for the use of his fine collection; ALEX. Morron, whose persistence alone prevented disaster during the incubation of this work; and R. M. Jounsron, for kindlv help whenever needed.

CLASSIFICATION.

In the Flora of a country or district it is customary to include only the races of plants that have developed true flowers, the races that stand in an intermediate position with their floral elements defined, but still dispersed or collected in cones (as in the Lycopods and Conifers and the more elaborated branch of Cryptogams), the Ferns that bear no flowers in the true sense, but whose principal development bears spores only.

The term flower is sometimes applied to the gametic reproductive organs of Cryptogams. This is not an exact use of the term. The name flower was given to and is considered to denote any specialised ageregation of foliar members on or about some of which are developed the organs that produce the spores in which takes’ place the rudimentary development that is homologous with the whole gametophytic generation of the Cryptogams.

The following is the scheme and definitions of the plants described :—

ANGIOSPERMS.—Plants in which the ovules are developed in more or less closed sacks. The spore-bearing members, the stamens and pistil, are in typical instances gathered into clusters surrounded by much-altered leaves, the whole specialised mass being termed a flower. In many primitive forms this type- condition has not been reached, in others various reductions from the perfect condition of the flower have taken place. But however much the flower may be simplified, there are no Angiosperms that stand on the border-land of this and any other division. The division is well-marked and circumscribed.

This division is composed of two very distinct and well marked classes.

Cuass 1—DICOTYLEDONS. Cuass 2.—-MONOCOTYLEDONS.

DicorrLepons, generally termed the Higher Flowering Plants, from their tissues and members having attained a more complex structure. The leaves are often very varied in shape, with the smaller vascular bundles forming a more or less intricate net of meshes in the green substance of the leaf, though in some few plants, ¢,f. Epacridacee, the veins are all or mostly parallel. The elements of the flowers are almost always in cycles of 4 or 5, rarely of 3 or6. The embryo, which is often sufficiently developed to completely exclude the albumen, has always two opposite seed-leaves or cotyledons, except in some parasitic plants, where even these members have been reduced out of existence. This class is here arranged as follows :—

Sub-Class 1.—Choripetale. Calyx and corolla normally present. Petals free from one another, except in few aberrant forms. Series 1.—Thalamiflore. Petals and stamens inserted into the torus below the pistil. Series 2.—Wisciflore. Petals and stamens inserted on or about a fleshy disk formed on the torus.

vi THE TASMANIAN FLORA.

Series 3.—Calciflore. Torus more or !ess developed into a tube that may be hardly apparent or grown to the full height of the pistil, and then often confluent with it. The petals and stamens inserted on this floral tube.

Sub-Class 2.—Gamopetale. Calyx and corolla normally present. Petals more or less united. Stamens usually inserted on the corolla-tube. Series 1.—Epigyne. Sepals and petals inserted on the top of the ovary.

Series 2.—Hypogyne. Ovary free, above the insertion of the corolla. Sub-Class 3.—Monvchalamydee. Perianth normally consisting of a single envelope, or (where double) not conspicuously differentiated. Plants of aprimitive type. Also including some reduced forms of doubtful affinity. The following is a linear classified list of Dicotyledonous Orders grouped in Alliances :—

The Mownocoty.epons, which are looked upon as a lower class of flowering plants, are notable chiefly for their leaves retaining a simple shape, parallel venation, and often sheathing bases. The cycles of the flowers are generally composed of 3 or 6members. The structure of the embryo is distinct, in the first leaf being solitary.

The Monocotyledons do not stand as an intervening link between Dicotyledons and lower plants, but form a well-marked group of specially-developed types from a primordial centre, some of the forms, as Graminee, being very specialised. At the same time, in the geologic record they greatly antedate the other class. Monocotyledons have been traced back even to the Carboniferous eva, while Dicotyledons only make their appearance just prior to the Cretaceous. No Tasmanian member of this division exceeds the condition of perennial herbs.

The following is the classification of the Monocotyledons here adopted :—

SuB-CLASS—PETALOIDE® EPIGYNE. Svus-cLass—PETaLOIDEH HYPOGYNE. Order lxxiv. Hydrocharidee. Order Ixxix. Ldiacee. lxxv. Orchidacee. lxxx. Ayridacee. lxxvi. Burmanmacee. Ixxxi. Juncacee. Ixxvii. IJridacee. lxxxii. Z'yphacee.

Ixxxvili. Cyperacee. lxxxix. Graminee.

GYMNOSPERMS.-—Plants in which typical ovules are developed and the gametic generation, though still very rudimentary, is much more defined than in Angiosperms. The ovules are not developed in closed sacks or carpels, but upon the upper surfaces of scale-like bracts, or may appear naked and terminal, sometimes more or less enclosed in a fleshy aril, microspores still maintaining the character of pollen and formed in well-developed stamens. Stamens and pistils often massed into cones, but no specialisation of members to form true flowers. :

The Gymnosperms, represented in the present day principally by Conifers, such as Pines, Cypresses, Yews, date back long before the time of Angiosperms, forms occurring as remotely as the Old Red Sandstone era. And whereas in the present day the Angiosperms contain as varied forms as perhaps they ever did, the Gymnosperms have long passed their prime, which appears to have been in the Mesozoic era. Also, though we have no evidence yet unfolded to demonstrate the descent of the great sub-divisions of the Angiosperms, we have abundant evidence of the close relationship of the Gymnosperms to the ferns through the Heterosporous Lycopods

lxxxv. Alismacee.

Representatives of only two orders occur in Tasmania :—

Cupressacee (Cypresses). Cover scales and ovuliferous scales entirely fused, forming somewhat solid cone scales that usually bear many ovules.

Taxacee (Yews). Ovuliferous scale wanting. . Cones never woody, generally succulent. Ovule sometimes solitary and immersed in a fleshy aril.

PTERYDOPHYTA.—( Fern-tribe).—Plants which do not develop flowers, and whose spore-bearing sacks are either developed in clusters or singly, upon the backs or margins, or sometimes immersed in the tissues of, leaves or at the base or axils of leaves. The spore-bearing leaves similar to the barren leaves, or sometimes greatly specialised, but never assuming the character of cones. Spores in some orders of two kinds, small and large; the small-spored sacks never assuming the specialised form of stamens, the microspores producing semi-enclosed gamophytic growth, in which are developed antheridia that produce motile gametes; the large-spored sacks producing megaspores that develop semi-enclosed gamophytic growth, in which is produced archegonia that develop each an ovum. This development of the megaspore differs in little but degree from the development taking place in the Gymmnosperms, only in the latter they remain attached to the parent plant, while in the former they are shed from the sporangia before, or soon after, commencing gamophytic development. In other orders the spores are all of one size; each spore grows into an independent being in the form of a flat, green, thalloid plant or prothallus, from a quarter to a few inches in size, with the essential organs of reproduction, the antheridia and archegonia, developed on the under surface.

The plants representing the Pterydophyta in our flora are few in number, and varied in structure. They are the remaining representatives of a vast and luxuriant flora that, dating back into early Palwozoic times, reached a marvellously rich development in the later Palzozoic ages, to dwindle down to a comparatively modest rank in the present day. We find accordingly that many present-day forms—little, retiring plants, with apparently no immediate relatives—are the sole surviving descendants of noble and important families.

CLASSIFICATION. ix

The Pterydophyta, on the whole, form a well-defined group, closely connected on one side with Gymnosperms, but on the other no immediate relationship to. lower plants can be traced. They may be classified as follows :—

Class Filicine (Fervs in the broadest sense). Sub-class Filices (True-ferns). Sub-class Hydropteride (Water-ferns).

Class Lycopodine (Club-mosses). Sub-class Lycopodiacee (Homosporous). Sub-class Selaginellacee (Heterosporus). Sub-class Isoétacee (Quill-worts).
