Some Hitherto Unknown Australian Plants. 1G9 



four or sometimes in two pairs, oval or broad-elliptic in 

 outline, almost sessile, a very conspicuous depressed glandule 

 between each pair ; leaflets in from four to twenty closely 

 approximated pairs, sessile, rather short, linear, flat, blunt at 

 the base, slightly acute at the apex, their carinular venule 

 faint ; rhacheole greenish-margined ; headlets of flowers 

 small, in elongated almost glabrous axillary and also 

 paniculate terminal racemes ; bracts minute, ciliolated, their 

 upper portion suddenly roundish-dilated ; calyx bluntly 

 , short-lobed, hardly half as long as the deeply five-cleft 

 corolla ; fruit straight, broadish, almost flatly compressed, 

 smooth, rather elongated, at both ends blunt, along the 

 anterior side dehiscent ; 'pericarp cartilaginous-chartaceous ; 

 seeds oblique-pendent, ovate-elliptic, much compressed, 

 black, with hardly any lustre, their areole on each side 

 large ; aiillar appendage pale, cymbous-semiorbicular, less 

 than half as long as the seed ; funicle comparatively short, 

 slightly twisted. 



A small tree of particularly graceful aspect ; leaves 

 crowded ; well developed pinnules about one inch long ; 

 leaflets generally from y^ to ^ inch broad ; headlets on very 

 thin stalklets of double or triple their length, containing 

 from 10 to 18 flowers; fruits mostly from 2 to 3 inches 

 long and about half an inch broad, dull-brownish outside ; 

 seeds scarcely a quarter of an inch long. 



This species seems always to have been passed as A. poly- 

 hotryct; but it differs essentially from that species in glabrous 

 leaves, with usually less numerous and always shorter 

 V pinnules, the form of which gives a very peculiar aspect to 

 the plant ; in smaller and particularly narrower leaflets, with 

 hardly any intervening spaces between them ; in highly 

 developed glandules on the rachis ; in glabrous thinner and 

 often also longer stalks of the headlets of flowers, with still 

 smaller basal bracts ; in deeper lobed corolla ; in broader 

 fruit not constricted between the seeds, further in probably 

 larger arillar appendage, so far as can be judged from com- 

 parison of fruit of A. polyhotrya, available here in a young 

 state only. Stature, bark, wood and odour of flowers of 

 the two trees may also be quite different. The height of 

 the tree, so far as known, seldom exceeds 1 5 feet ; the bark 

 is of a greyish or slaty colour and smooth ; the flowering 

 time is about the earlier part of September. 



The species is named in honour of Mr. F. M. Bailey, from 

 whom flowering branchlets were received, taken at Brisbane
