THE BOTANY OF THE KIMBERLEYS, NORTH-WEST AUSTRALIA,
By Wititiam VINCENT FITZGERALD.
(Communicated by J. H. Maiden, I.8.0., F.R.S., Honorary Member.)
Note by Communicator—Mr. Fitzgerald was attached to two expeditions, viz., that of C. Crossland in 1905, and one in the fol- lowing year. A note on the botanical work will be found in my “Notes on Acacia, No. li., Tropical Western Australia,’ in Pros. Roy. Soc., N.S.W. li., 106, 1917. The few specimens collected by Dr. House, collected on the F. 8. Brockman expedition of 1901 are referred to, op. cit. p. 104, and are included by Mr. Fitzgerald in the present paper.
From time to time I brought before the Royal Society of New South Wales (Vols. xlvii., 221 (1913); xlix., 317, 318, (1915); li, 445 (1917) ) notes on or descriptions of Eucalypts collected by Mr. Fitzgerald, embodying his notes or descriptions where avail- able.
Concerning Acacia, the same remarks apply as regards tropical species, to my papers in Proc. Roy. Soc., N.S.W. li, 71 (1917) and “The Flora of the Northern Territory” (Ewart and Davies), published by the Federal Government, 1917, Appendix iv., Acacias, p. 318. As regards Extra-tropical species, Proc. Roy. Soc., N.S.1W. li., 238 (1917).
On 11th April, 1916, I received from Mr. Fitzgerald, the day after his departure on active service, his M.S. on Western Aus- tralian plants, together with some herbarium specimens. With the author away from Australia (he recently returned wounded), I acted in his interests as well as I could. Some few remaining Eucalyptus notes I will continue to publish in the Royal Society, New South Wales, series of papers, and others in my Critical Re- vision of the genus.
A Hydrocharidiacea, which on receipt of the manuscripts I found Mr. Fitzgerald had described (but not published) had been forwarded by me to Dr. A. B. Rendle, F.R.S., of the British Mu- seum, a specialist on this Family, as far back as July, 1915.
No opportunity presented itself of dealing with Mr. Fitzger- ald’s manuscripts in 1916. I divided them into three parts (a) The present portion, which deals with the tropical (chiefly Kimber-
2
ley) plants. This is by far the most valuable. I have re-arranged it but have not otherwise interfered with it. () Some notes on other Western Australian plants; valuable, but not so urgent. (e) Descriptions of Western Australian plants already published by Mr. Fitzgerald. It was evidently the intention of Mr. Fitzgerald to publish (a), (b), and (ce) as a complete work, and this would have been very convenient. Of course no scientific journal would republish (¢). It is regretted that the present paper was not pub- lished years ago, but financial difficulties apparently stood in the way.
During the last ten years I obtained a number of specimens of Mr. Fitzgerald’s collecting by purchase from a former business partner of his. A few others I had received at odd times from Dr. Stoward, Botanist and Plant Pathologist of the Western Australian Department of Agriculture. In April, 1917, I received from Dr. Stoward specimens of 53 species now described in this paper. These are in the National Herbarium of Sydney, and the original set is with Dr. Stoward at Perth. Many of the species will have to be re-collected before material is available for other herbaria.
Mr. Fitzgerald’s paper deals with one of the important terrae incognitae of Australia. This has been brought home to me fre- quently, as small collections from North-Western Australia are from time to time received. Accordingly, long before I became the trustee of Mr. Fitzgerald’s manuscripts, I had prepared a botanical bibliography of the region, which is attached to my Acacia paper (Journ. Roy. Soc. N.S.W., li. 71 (1917), the chief value of the purely botanical, porton of which is based on Mr. Fitzgerald’s ma- terial received from Dr. Stoward.

His paper therefore contains descriptions of—
2 new genera 88 new species 5 new varieties
and from that circumstance also becomes a most important contri- bution to Australian botany. The new species of Acacia and Euea- lypts are not included, having been dealt with elsewhere, as already stated. This would increase the number of species by at least six, making 94 in all.
It would be desirable to make a comprehensive statement in regard to the flora of North-West Australia, and my bibliography will be useful in this connection, but it is not desirable to increase the length of the present paper. In a few cases Mr. Fitzgerald has not given specific localities, and in cases in which a species occurs in extra-tropical areas, I have been careful to only present such of Mr. Fitzgerald’s notes as refer, at least in part, to tropical speci- mens.
The Northern Territory and North-West Australia being con- tiguous country, it will be most instructive to compare Ewart and Davies’ “Flora of the Northern Territory,” published last month (December, 1917), with the present paper, but to do this would delay publication of Mr. Fitzgerald’s paper, and would also raise the question of additional cost.
The following brief account of the physiograhpy of the area dealt with was supplied by Mr. Fitzgerald. The author has also some fuller notes on the geology of the region which are less in place in a purely botanical paper.
The part specifically detailed extends due east of King Sound and is typical of the country bounded on the south by the Fitzroy River.
The principal mountain chains are the King Leopold Ranges which bear west of north to Walcott Inlet. Mount Broome is the highest point, but does not exceed 1,900 feet above the north-eastern base. Away to the west and parallel with the ranges is a low rugged- looking one known as the Napier Range, and beyond, for a distance
5
of roughly 100 miles, when King Sound is reached, are a series of sandy, scrubby undulations and grassy plains. To the east of the King Leopold Ranges, looking from Mount Broome, the country in configuration consists of ranges and _ table- lands, with undulations, and extensive plains intervening, be- sides isolated mountains which rise above the surrounding country like islands from an ocean. The whole are intersected by numerous watercourses which, during the wet season, carry huge volumes of water, and always contain large permanent pools, or are running in part throughout the whole year. The elevations are faced by fre- quently unsealable cliffs of 50 to above 500 feet in height, whilst the rivers do not uniformly follow the base of the ranges, but in- stead often cut clean through them, forming wildly picturesque and precipitous gorges The following are some examples :—

Trees often leafless when in fruit. Stock readily eat the young
The
foliage, and the acid floury contents of the fruits along with the seeds are eaten by the aborigines, both being made into a kind of bread. Occasionally the larger trees have deep hollows at the base of the main branches in which is stored quantities of drinkable water which is utilised by the aborigines during dry periods. The species being a tardy reproducer, young plants are very seldom seen,
trees evidently attain a great age, because there is no authentic record of one being found dead. An inhabitant of sandy loams overlying quartzite or sandstone.
