78 Materials for a Flora of the Malayan Peninsula. 



Flor. Ind. Bat. I, 204 ; Bak. in Flor. Brifc. Ind. II, 194. Sapindacea 

 Wall. Cat. 8082. BiUea acuminata Wall. Cat. 5443. 



Penang ; Wallich 8082 ! Andamans ; common, King's Collectors ! 

 DiSTRiB. Martaban. 



The solitary Malayan specimen at Calcutta that appears referable to this species 

 is one issued by Dr. Wallich as Sapindacea sp. {Cat. n. 80S2) ; this specimen is not 

 dealt with in the Flora of British India. So far as it goes it agrees better with 

 Dr. Wallich's Martaban specimens of S. acuminutus (Cat. n. 5443) than it does with 

 any Malayan species of SpatholoMcs, to which genus it manifestly belongs ; the 

 specimen is, however, only in very youug flower. No one has met with it in Penang 

 since Dr. Wallich collected it. 



Mr. Baker's description of S. acuminatus does not apply to Dr. Wallich's Butea 

 acuminata in so far as the lengths of the panicles and of the pedicels are concerned. 

 His description would apply to Wall. Cat. 5907 (Pongamia rosea Gh-ah.) whicli Mr. 

 Baker also includes here ; Pongamia rosea certainly is a Spatholohus but is a species 

 very distinct from S. acuminatus. There are not at Calcutta examples of Wall. Cat, 

 5908 or Wall. Cat. 9054 ; both are here excladed because Mr. Baker expresses a 

 doubt regarding both. The first may indeed prove to be the same as Spatholohus 

 riparius Prain ; of the second nothing can be said because, in the Flora of British 

 India, it is referred not only to S. acuminatus, but also to Derris thyrsijiora. 



The Andamans specimens are absolutely identical with Wallich's original 

 specimens {Cat. 5443) from Martaban. 



5. Spatholobus dubius Prain. A large climber 100-1 50 feet long, 

 stem 6-8 in. diam. witli roand adpressed-puberulous branches. Leaves 

 6-8 in. long ; leaflets 3 ovate-acuminate base rounded the tip slightly 

 mucronate, coriaceous glossy bright green, glabrescent. above adpressed- 

 puberulous beneath, lateral nerves ascending 8-9 " pairs prominent 

 beneath, cross-nerves distinct ; terminal 2-6 in. long 15-3 in. wide, 

 lateral subsimilar rather smaller; petioles 1"5 in. long puberulous, 

 petiolules "15 in. pubescent ; stipels subulate •15-'2 in. long, stipules 

 lanceolate '2 in. deciduous ; leaves towards ends of branches sometimes 

 1-foliolate. Inflorescence in terminal and axillary spreading panicles 

 the former sometimes 8 in. the latter 4 in. long, sometimes 2-3 from 

 same axil. Bracts lanceolate persistent ndpressed-pubescent "15 in. 

 long equalling the pubescent solitary or fasciculate pedicels; bracteoles 

 minnte. Calyx adpressed-pubescent, '12 in., campanulate, teeth short 

 triangular except the 2-fid upper. Corolla '25 in. long, pure white, 

 standard orbicular retuse. Pod not seen.

A very distinct species apparently nearest to S. littoralis Hassk. from whicli it 

 differs tn having the lower lip of calyx toothed and the leaves uniformly puberulous 

 beneath. The shortness of its petiolules, which are equalled and often exceeded in 

 length by the subulate stipels, renders the species easily distinguishable.
