Baker ex descr. is probably a synonym), B. diptera Blume, B. elongata 

 Korth., B. excelsa Blume (B. ferruginea Korth., non Roxb.), B. excurrens 

 Stapf, B. finlaysoniana Grab.., B. foraminifer Gagnep., B. kingii Prain, B. 

 macropoda Blume, B. menispermacea Gagnep., B. semibifida Roxb., and B. 

 stenostachya Baker. More than one-half of these are known only from 

 Borneo. The species proposed below are apparently distinct from the 

 above-listed species, and from all other described Malayan forms. Several 

 of the above species, notably Bauhinia burbidgei Stapf, B. foraminifer 

 Gagnep., and B. menispermacea Gagnep., are represented in our recently 

 collected material by fine series of specimens. 



BAUHINIA BORNEENSIS sp. nov. § Phanera. 



Frutex scandens, ramulis inflorescentiisque dense subferrugi- 

 neo-pubescentibus ; foliis late ellipticis, coriaceis usque ad 8 cm 

 longis, basi cordatis, 11- ad 15-nerviis, subtus minute pubescent- 

 ibus, apice usque ad ^ vel \ divisis, lobis late rotundatis ; racemis 

 terminalibus, floribus longe pedicellatis, saltern 2.5 cm longis, 

 petalis extus parcissime longe pilosis glabrescentibus. 



A scandent shrub, the younger parts and the inflorescence 

 densely pubescent with brown or ferruginous short hairs. 

 Branches terete, brown, glabrous, lenticellate. Leaves coriace- 

 ous, broadly elliptic, 5 to 8 cm long, 4 to 8 cm wide, the upper 

 surface dark-brown, glabrous, the lower minutely appressed 

 ferruginous-pubescent, base cordate, 11- to 15-nerved, apex 

 divided from one-fourth to one-third to the base, the sinus 

 narrow, lobes equilateral, broadly rounded; petioles 2 to 3.5 cm 

 long, ultimately glabrous. Racemes terminal, simple, densely 

 pubescent, up to at least 20 cm in length, the pedicels densely 

 pubescent, 3 to 4 cm long. Buds broadly clavate, the tube cylin- 

 dric, somewhat gibbous at the base, 1 cm long, the limb oblong- 

 cylindric, rounded or apiculate, just before anthesis about 2 cm 

 long, striate. Sepals narrowly oblong, about 2.5 cm long, 6.5 

 mm wide, somewhat acuminate, coriaceous. Petals as long as 

 the sepals, glabrous or with a very few, long, scattered hairs on 

 the median portion of the back, the limb oblong to oblong-elliptic, 

 rounded, up to 11 mm wide, base acute, claw 2 to 3 mm long. 

 Fertile stamens 3 ; anthers oblong, 12 mm long. Ovary and stout 

 style densely appressed ferruginous-pubescent. 



Sarawak, Native collector 1906 (type), 1040, 1787, 1874 (Bur. Sci.) ; 

 possibly referable here is Hose 575 from Baram District, but in my specimen, 

 which presents rather young buds, the petals are densely pubescent on the 

 median part of the back. 



A species in the group with Bauhinia ferruginea Roxb., from which 

 it is distinguished by its petals being quite glabrous, or at most with very 

 few, long, soft hairs on the median portions of the back, not densely 

 tomentose.
