A very distinct species, which has in the field been referred by Father Scorte- 

 chini to Derris § Aganope and supposed by that learned botanist to be perhaps 

 Miquel's Derris macrophylla. The presence sometimes, though not always, of stip^ls 

 shows, however, that the plant cannot well be a Derris and indicates that it is almost 

 certainly a Spatholobus. It is unfortunate that, of all the gatherings reported, not 

 one should be in fruit. 



7. Spatholobds dubius Prain, Journ. As. Soc. Beng. lxvi. 2. 79 ; 

 leaflets rigid-ovate, acute, rounded at the base, adpressed-puberulous 

 "beneath, flowers small, calyx adpressed-pubesceut, teeth half as long as 

 tube triagular except the 2-fid npper ; pod unknown. 



Perak ; on Gunong Bubu, Kunstler 7585 ! Penang ; Curtis ! 



A large climber 100-150 feet long, stem 6-8 in. in diam. Leaflets like those of 

 S. Maingayi but thinner, adpressed-puberulous beneath, and often larger, 2-6 in; 

 long, l'5-3 in. wide ; the upper leaves are at times 1-foliolate as in S. bracteolatus and 

 in S. littoralis Hassk. Inflorescence in terminal and axillary spreading panicles, the 

 former 8 in. the latter 4 in. long, sometimes several in same axil. Bract* small per- 

 sistent. Calyx "12 in. long. Corolla '25 in. long, pure-white, standard orbicular retuse. 



Also a very distinct species, but, like the preceding, in the absence of fruit not 

 absolutely certainly a Spatholobus. . It appears to be nearest to S. littoralis Hassk., 

 from which it differs in having the lip of calyx toothed and in having the leaves 

 » uniformly adpressed-puberulous beneath. 



8. Spatholobus Ridleyi Prain, Journ. As. Soc. Beng. lxvi. 2. 80; 

 leaflets rigid, chartaceous, oblanceolate, apex acuminate, quite glabrous 

 beneath, flowers small, calyx adpressed-pubescent, teeth very unequal, 

 upper truncate the others rounded half as long as tube, pod sessile 

 narrowed to the tip. 



Singapore ; cult, in Bot. Garden, original locality not given ; Ridley 

 6401 ! 



A climber with glabrous, slightly angled branches. Leaflets bright-green shining 

 above, 3-35 in. long, 1-1*25 in. wide. Inflorescence in axillary racemes 3 in. long. 

 Pedicels rather larger than calyx. Calyx *12 in. Corolla *25 in. long, white, standard 

 orbicular, limb slightly auriculate at base, apex retuse. Pod 4 in. long, 1 in. across 

 below. *4 in. wide at opaque seed-bearing tip ; membranous part sparsely puberulous, 

 reticulate-veined. 



A very distinct species, though nearest to S. macropterus Miq., from Sumatra.

There is only one species ; therefore Mr. Bentham's name, which is nine years 

 prior to that used in the F. B. I., must stand.
