Branchlets copious, spreading, or at first curved downward. 

 Leaves one-sixth to one-quarter inch long. Bracts ahnost leaf-like ; 

 braoteoles short. Calyx measuring only one-quarter of an inch 

 in length, before expansion somewhat pyramidal and prominently 

 angled. Petals not much extended beyond the calyx, the upper 

 orbicular, slightly lobed at both extremities. Style wlien young 

 strongly incurved. Ovules two. Fi'uit unobtained. 



The ^ only other Burtonia with simple leaves, namely 

 ]j. conferta, is very different, already in want of indument, less 

 ramification, longer leaves, larger flowers on well-developed 

 stalklets, color of petals, form of anthers and most likely also in 

 fruit-characteristics. In general aspect, as well as smallness of 

 leaves and flowers, our new .species approaches .5. gompholohioides, 

 but that plant is otherwise widely distinct. 



•Jack.sonia poliosa, Turcz. VV.A., Victoria Desert (C. 48, 

 C. 54, C. 58) ; near Knutsford. A plant collected at Camp 58 

 seems a more ramulose variety of this species ; but as yet no 

 fruits are known from any of the localities. 



Jacksonia nematoclada, /'' .V. M. W.A., near Gnarlbine. 

 Professor Greene has recently proposed, that the Australian 

 genus Jacksonia should be superseded by Piptomeris, because 

 Bafinesque utilised some few years before R. Brown the name 

 J^aoksonia, giving it generically to a species of Gleome, which 

 appellation, however, he subsequently changed to Polanisia. 

 But that genus became suppressed for Australia many years ago, 

 and subsequently for Africa by Prof. Oliver. As the one 

 American species, on which Polanisia was founded, differs only 

 in trifling respects from other Cleomes, it seems best to restore it 

 (perhaps sectionally) to its original systematic position. 



Daviesia bkevifolia, Lindley. W.A., near Gnarlbine • Vic-, 

 toria Desert (C. 54). 



Daviesia paciiylina, Turcz. W.A., Fraser Range (1 ft.) ; 

 Warangering, a glabrous state with much longer leaves. Tlie 

 acuminate long calyx-lobes are characteristic for this species ; the 

 orm now mentioned reminds, as regards leaves, much of 

 • ^ongifolia, in which species sometimes also acuminate leaves 

 Occur ; if specific differences should exist between the two, then 

 ripe fruits (unavailable here) must show this. The long-lobed 

 calyx separates this plant from D. polyphylla. 



Daviesia apiiylla, F. v. M. Young fruit flat, semiorbicular- 

 tieltoid, on a very short stipe. W.A., Victoria Desert (C. 56) ■ 

 near Praser Range (C. 68) ; 20 miles N.W. from Fraser Range' 

 'non of the natives of Hampton Plain. 



Daviesia acanthoclona, F. r. M. W.A., Victoria Desert 



I • 54) and near Gnarlbine. Fruit (hitherto unknown) only 



bout one-third of an inch long and broad, rhomboid-orbicular.
