young, becoming quite glabrous ; lateral nerves about 7 on each 

 side of the midrib, slender, not prominent ; petiole, including the 

 petiolule, 1 to 1.5 cm long. Inflorescence axillary, cymose, fer- 

 ruginous-pubescent, 2 to 3 cm long. Flowers about 6 mm long, 

 their pedicels 1 to 2 mm in length, sparingly pubescent. Calyx 

 somewhat cup-shaped, 3.5 mm long, sparingly appressed-pubes- 

 cent, shortly 5-toothed, three of the teeth narrower than the 

 other two. Petals sparingly pubescent externally. Standard 

 with an orbicular, rounded limb about 3 mm in diameter, re- 

 flexed in anthesis, the claw slender. Keel petals as long as the 

 standard, prominently hastate or appendaged at the base, the 

 claw slender, 2.5 mm long, the limb inequilateral, oblong-obovate, 

 somewhat falcate, rounded. Stamens united into two phalanges 

 of four each, with an intermediate one between the phalanges, 

 the vexillary filament wanting. Ovary narrowly oblong, stipi- 

 tate, densely and minutely ferruginous-pubescent, the style subu- 

 late, about 2 mm long. 



Sarawak, Baram District, Miri, Hose 678, April, 1895. 



A species well characterized by its unifoliolate leaves; the single leaflet 

 comparatively large, castaneous and shining when dry, and of nearly the 

 same color on both surfaces; and its short inflorescences. It is manifestly 

 very closely allied to Dalbergia sub alterni folia (Elm.) Merr. of Pala- 

 wan and Sarawak, which, however, has much longer inflorescences and 

 3-foliolate leaves. 



PTEROLOBIUM R. Brown 



PTEROLOBIUM BORNEENSE sp. nov. 



Frutex scandens, aculeatus, inflorescentiis foliisque exceptis 

 glaber; foliis circiter 20 cm longis, rhachibus griseo-puberulis, 

 pinnis circiter 10-jugatis, 4 ad 6 cm longis; foliolis 10- ad 14- 

 jugatis, glabris, anguste oblongis, circiter 1 cm longis, 3 ad 4 mm 

 latis, apice rotundatis, leviter retusis, basi inaequilateralibus ; 

 inflorescentiis dense pubescentibus, circiter 20 cm longis, flori- 

 bus numerosis; leguminis glabris, 5 cm longis, circiter 1.4 cm 

 latis, basi turgidis, obscure reticulatis, apice late rotundatis, later- 

 aliter apiculatis. 



A scandent shrub, the branches terete, smooth, dark-colored, 

 glabrous, somewhat pruinose when dry, armed with short re- 

 flexed spines at the nodes. Leaves about 20 cm long, the rachis 

 with short retrorse spines at the nodes, griseous-puberulent as 

 are also the rachises of the pinnae ; pinnae about 10 pairs, 4 to 6 

 cm long ; leaflets 10 to 14 pairs, narrowly oblong, glabrous, dark- 

 brown when dry, about 1 cm long, 3 to 4 mm wide, apex rounded, 

 usually retuse and sometimes with a minute apiculus, base inequi- 

 lateral, rounded, the lamina extending farther along the petiolule
