THE HONORABLE ALFRED DEAKIN, M.L.A.,

CHIEF SECRETARY OF THE COLONY VICTORIA,

ALL

SCIENTIFIC PROGRESS IN THIS HIS NATIVE LAND
IS STRENUOUSLY PROMOTED,

AND

UNDER WHOSE GENEROUS MINISTERIAL AUSPICES

This Volume has been Elaborated*

PREFACE.

THIS work owes its origin to a desire, expressed by the Field-
Naturalists' Club of Victoria, at the instance of the Honorable
.Dr. Dobson, that its members should be provided with a literary
guide similar to the meritorious " Handbook of the Plants of
Tasmania," written some years ago by the Rev. W. Spicer, for
facilitating the study of our native flora, particularly during
botanical excursions ; and it was especially urged by the honor-
able and distinguished gentleman, that the dichotomous method
of Lamarck, which was followed by our late lamented friend for
:his book, should also be adopted for the Victorian work. The
flora of our colony being doubly as rich in species as that of
Tasmania rendered the task, even under ordinary circumstances,
far more laborious ; moreover, it was felt by the writer of these
lines, that an effort should be made, while applying the difficult
method mentioned, not to disrupt in any way the chain of affinity,
which links the orders and the genera and the species of plants
naturally together. Furthermore, the necessity of supporting the
very brief dichotomous notes by diagnostic descriptions was also
at once recognised ; hence the dichotomous " Key " was required
to be extended to an abridged "Descriptive Flora." To render
the contemplated work acceptable as well to the juvenile tyro as
to the advanced student — it being the first special and early com-
pleted work on the indigenous vegetation of this colony — it became
imperative, to express the characteristics of the plants not only
with etymologic precision and logical clearness, but also with the
utmost of plainness and organographic simplification. The work
Indeed was to be rendered alike available for elementary schools

vi Preface.

and for high educational institutions ; it was to serve the amateur-
gatherer of plants in the field as well as the professional investi-
gator in the exercise of stern duties ; and yet such a work was to
be inexpensive, concise and reliable. How far all these aspira-
tions have been realized, the practical use of the work now
completed must demonstrate ; the ardent endeavour of the author
at all events has been, to succeed in the use of a method, which
was chosen not at his free will, and under such restraint to produce
a work, which would render the study of plants in our dominion
more universal, and which could with some credit to the colony
be placed even into the libraries of the world.

The organographic alterations, largely introduced into these
pages for the first time, in contrast to zoologic terms, have been
ventured on only tentatively, but without thereby in any manner
impairing the use of the work ; indeed they arose mainly from a
desire of the author, to simplify the wordings for organs of plants in
a book, written especially for almost a new country and particularly
for the juvenile portion of its population. This subject of desirable
changes in organography by simplifying verbiage and by keeping
apart from each other zoographic and phytographic expressions,
has comprehensively been discussed in a treatise, which was written
for the Sydney-meeting of the Australian Association for the
advancement of Science, and which has been promulgated by the
Royal Society of New South Wales already. The main reasons
for adopting some alterations in the Candollean system, also for
the present publication, have been set forth some years ago in
the " Systematic Census of Australian Plants with chronologic*
literary and geographic annotations." Before any opinion is formed
on these novations, the writings referred to should be studied with
attentive care.

The elaboration of this volume could have been very much
facilitated, had simply a negative expression been chosen, whenever a
difficulty arose in searching for a contrasting phrase in the dualism
of the dichotomy, or had the characteristics of orders and of genera

Preface. vii

been so limited, as to apply merely to Victorian species, or had
repetitions in the dichotomy not been entirely avoided. Then, as
stated already, the difficulty presented itself, to maintain closely
and uninterruptedly a systematic arrangement expressive of
consecutive nearest affinities. Again, only such marks of separa-
tion could be seized on, as at a glance would be apparent even to-
the unarmed eyes, and as would not be liable to considerable
inconstancy ; thus then embryonic characteristics and any others,
either much concealed or very minute, however important they might
be, could not be drawn, unless exceptionally, into use for a work,
which was to serve expeditious field-engagements mainly. Where
in some few cases the author was compelled, to resort to the
description of minute organs for discrimination, simply no other
characteristics existed for separating the complex of some plants
from that of some others ; but even in the instance of seizing on
the only mark of distinction, by which the Salsolaceae and allied
orders can comprehensively be removed from some other ordinal
groups, the mere crushing of a seed will suffice for recognising
instantly, even without microscopic aid of any kind, the starchy
contents of the seeds and the remarkable form of its embryo.
With the same ease might almost the detail-floral structure of our
numerous Acacias be noted as demonstrating differences of
externally similar species; and on this particular subject infor-
mation for home-studies might be sought in the " Iconography of
Australian Acacias " recently issued.

The number of the species, admitted into this work, had they
been treated in a less conservative sense, could have been largely
augmented; but when we see, to cite an example, how in perhaps
a thousand plants of Caladenia Patersoni, the most beautiful and
also the most widely distributed of our terrestrial orchids, hardly
two are quite alike as regards their flowers, while the majority of
the individual plants are so sportive, that the species became
described under several names by various writers, we should pause,
ere we attempt to circumscribe supposed specific forms, and leave

•viii Preface.

the discrimination of them for varieties or otherwise to more
extended studies in the field here and also in other parts of
Australia: The separating of varieties of any species were beyond
the scope of the present pages. Literary quotations and synonymy
are also excluded from this work. In any future impression some
of the characteristics, adopted as specific, could likely with
advantage be transferred to generic notes ; so also some primary
notes in the dichotomy may hereafter become subsidiary or
affirmative and vice versa.

It would be advisable, that whoever may use methodically this
book, should provide a blank volume, correspondingly paged, for
entries on soil, stature, measurements, regional elevation, odor,
color, locality and copiousness or scarcity of any plant, with a
view of subsequently "comparing notes," for instance on flowering
time, phaenologic data, as aiding meterologic observations, having
in late years become quite a science-branch in Phytology by itself.
Be it remembered, however, that identical plants are flowering
nearly three months later in our Alps than in the north-western
lowlands ; some practical application to this particular subject has
been recently given in the seventh edition of the " select plants for
industrial culture and naturalisation." Thus also what may be
frequent in one locality may be rare in another. Which regions
still need closer investigation for their floral treasures, and what
number of additional species may still be expected as gatherable
within our territory, has been noted in a late number of the
" Field-Naturalist." Our knowledge requires also yet to be per-
fected in reference to the permanency of some of the characteristics,
.assigned to species of such genera of much complicated forms, as
Rhagodia, Atriplex, Swainsona, Leptospermum, Pultenaea, Stack-
housia, Opercularia, Epacris, Euphrasia, Prasophyllum, Pterostylis,
Xerotes, Scirpus, Lepyrodia, Stipa, Danthonia, Agrostis, Lepi-
dosperma, because here in a comparatively young colony the
whole cyclus of forms, within which species range, particularly in
climatic regions so extensively varied as ours, is not in all cases yet

Preface. ix

sufficiently ascertained; indeed the degree of variability, which
should be assigned to plants truly specifically different, is not yet
fully determined for all, even in the vegetation at some of the
oldest seats of learning in the world. Several of the species, stand-
ing in need of critical re-elaboration, are restricted to remote
regions of our territory, where these particular plants in their
native haunts could not yet be traced through all their states,
whether normal or aberrant.

Some few generic alterations in the descriptive volume were
made, to fit the respective plants easier into the dichotomic
arrangement, but only in cases where the generic position would
seem optional ; still in some instances the change was demanded
by more recent researches on ampler material, and so it was in a
few cases as regards specific names. Doubtless indeed the
records of the characteristics could be augmented and occasionally
improved from future researches ; but at all events a solid basis is
now gained, on which to enlarge or embellish hereafter the literary
structure now offered. The descriptive details were kept more
curt in the earlier portion of the work, than in the later ; but in
the " Native Plants of Victoria " rather full descriptions are given
for all " hypogynous choripetaleae " before this, to which might be
referred, and that work can now most easily be continued and
completed, as the elaborated main notes and all necessary illustra-
tions are now extant through the present publication. But, as
much more important, may be remarked, that of nearly the whole
of the 1,900 vascular plants, known as indigenous to Victoria, full
descriptions are given long ago in the seven volumes of the Aus-
tralian Flora, which emanated mainly from the genius, the assiduity
and the life-long experience of the late George Bentham, aid being
afforded by vast material and subsidiary notes from here ; really
we would have had no cause for special writings on the Flora of
this colony as a whole, were it not desirable to have our own plants
treated in a concise and inexpensive publication here locally.
For delimitation of genera the celebrated work of Bentham and

Preface.

Hooker was always a safe guide, though the sequence as adopted
by the authors of that great opus was not in all instances adhered
to for the present volume.

The multifarious demand on the author's time did not allow, to
check by autopsy all the diagnostic definitions now offered, as the
close inspection of the whole vast botanic treasures, accumulated
by him in Australia since 1847, demonstrative of manifold degrees
of variability, would have retarded the appearance of this volume
still further, than already has been the case, he being anxious to
carry through the work not only conscientiously but also within a
reasonable extent of time. Minor alterations and perhaps unim-
portant additions, can gradually be effected for supplemental pages
or perhaps new editions. Indeed, some species of plants had to be
laid aside, while the elaboration was progressing, to be dealt with
in time-taking critical examination at an early future.

If methodically followed, the dichotomy should safely lead up
to any of our numerous indigenous plants, the name of which
is to be ascertained. But the tyro may find it in first instance
most convenient, to consult the many xylographic illustrations,
from which he ought to be able to recognise with the utmost
ease many of the species, indigenous in the surrounding vegetation;
he will have further the aid of the vernacular index, though this
was kept purposely brief; he can then also refer to a large number
of indications of very obvious outer marks, some of which will
lead the young disciple at once to various kinds of plants, with
which from striking external characteristics even the least observant
child must be familiar already from mere memory. The grouped
miscellaneous characteristics just referred to were suggested by prin-
ciples, first used in the volume oh " Select Plants for Industrial
Culture and Naturalisation (1872)," with a view of grouping
generically together the utilitarian plants of the globe according to
their various qualities and applications. On the groups of genera,
thus formed, arbitrary arrangements for any key different to this
might be founded, should such be preferred by any worker on our

Preface. xi

native plants to a truly systematic placement ; but then endless
difficulties would have to be encountered in dealing with the large
remainder of the plants, after the characteristics of these miscel-
laneous and unsystematic groups had been exhausted.

It was not deemed advisable, to burden this volume with
descriptive definitions of immigrated plants, as the book exceeds
already the space originally assigned to it ; but the majority of the
plants hitherto naturalized are of wide distribution in Europe, and
therefore descriptions of them are contained in any of the works
on the British flora, and these are readily accessible also here. A
list however of the non-Australian plants, permanently established
on Victorian soil already, is given towards the end of this volume ;
but with an admission only of those of their popular names, which
are neither ambiguous nor unmeaning. A vocabulary of botanic
expressions was also considered unnecessary for these pages,
because what little of wording was adopted from the ancien
languages for our present plain literary purpose became explained
simultaneously with the expositions of the analytic details of the
numerous woodcut-illustrations. Definite measurements of plants
or their organs have not been regarded as needful for descriptions
necessary to be brief; dimensions always range within wide or
uncertain limits, comparative data being quite sufficient for what
concerns us here at present. All the measurements of the
xylographic main-delineations are purposely kept to natural size,
diminuation of figures of plants being always objectionable as not
conveying a fair idea of their subject. Whenever any plants are
indicated as alpine, as maritime or as otherwise restricted, it is
to be understood, that they are thus far exclusively localized ; yet
it is to be remembered, that about one hundred species of our
phanerogamous lowland-plants ascend the Australian Alps, and
that a still larger number of our various inland-plants approach the
shores of our southern ocean.

A few typographical and scriptorial errors eluded timely obser-
vation; but they seem so insignificant, that it was not deemed

xii Preface.

worth while to effect the formal corrections already in the present •
issue of the work ; in a future one some discrepancies, as regards
the wordings used for the first and for the second part of this
edition, can also be reconciled. Abbreviations have been avoided
throughout the text. Their use involves mental extra-exertions, is
confusing particularly to tyros and perhaps even deterring to
them, while all that possibly could be derived from a procedure of
shortening words or by employing symbolic renderings, would be,
to save a few pages printing in any popular small work of the kind
here under consideration.

Although for an official publication like this rights cannot be
reserved, yet it is hoped, in the interest of the Public Department,
from which it emanated, that its originalities will be duly respected.
The permission for extensively transcribing (even under some
modifications) from these pages can only be conceded on terms of
fullest literary acknowledgment. But it may at once here be
mentioned, that when the results of this season's Victorian work in
botanizing shall have been attained, an extra-print of the dichotomic
notes will be furnished, into which the various new acquisitions to
the records of the Victorian flora can then also be embodied.
Indeed, for local publications to find out the names of plants,
occurring at any town or in any district of Victoria, the sole
reconstruction of the dichotomic notes would likely suffice, unless
subsidiary notes, though still more brief, were added also — inas-
much as the present main-work would be readily at hand — so that
the respective " Florules " could be brought out easily and inex-
pensively after fairly extensive botanic searches through any of the
delimited floral areas have been instituted.

It remains for the author gratefully to acknowledge that Mr. G.
Luehmann, Senior Assistant in the Phytologic Department of
Melbourne, has aided extensively in setting out the dichotomic
phrases, after their elaboration and graduation had been com-
pleted, and that he as well as Mr. Ch. French, junior, an office-
assistant, gave much help in carrying out the clerical portion of

Preface. xiii

the engagements for producing this volume. In concluding these
prefatory remarks the writer may still point out, that plants are
more readily accessible, more easily prepared and more com-
modiously kept, than any other naturalist's collections. Any such
gatherings, however small at the commencement, may therefore
become permanent; they may add to the objects for mental
training and joyous engagements far beyond ^what by the youthful
observer could be surmised playfully at the outset; they may
exercise indeed an influence on a whole life, and they suredly
should always lead up to contemplations of the godly power, from
which the endless and marvellous forms of nature derive their
origin,' their design and their maintenance.
