416 D. Prain — Some additional Leguminosse. [No. 2, 



3/. Spatholobus me rguensis Prain; leaflets very thick and rigid, 

 oblong shortly cuspidate, base rather narrowly cuneate, quite glabrous 

 on both surfaces, panicles rather shorter than leaves, bracts at their 

 origin small, calyx finely downy, teeth triangular half as long as tube ; 

 pod not seen. 



Mergui Archipelago ; J. Anderson ! Proudlock ! 



A strong climber, branches glabrous lenticelled. Petiole '5-1 "5 in., leaflets 4 in. 

 long, 2 in. wide. Panicle 3-5 in. long, almost equalling the leaves, peduncles with a 

 few small scarious bracts at its origin from stem. Pedicels as long as calyx. Calyx 

 '1 in., teeth subacute. Corolla claret-coloured. 



Very near to 8. Listeri and 8. roseus ; while resembling these in inflorescence 

 it has a different calyx and very dissimilar leaves. The leaves, though somewhat 

 unlike in shape, have the venation and consistence of those of 8. crassifolius which 

 species has, however, a totally distinct inflorescence and quite different flowers. 



5. Spatholobus riparius Prain ; leaflets thick, very rigid, obovate- 

 obtuse, cuneate at base, lateral slightly obliquely, glabrous above, 

 sparsely shortly puberulous on the nerves beneath, flowers small, calyx 

 obscurely downy, upper and lower teeth oblong, lateral triangular, 

 nearly as long as the tube, pod sessile narrowed to the tip. 



Tenasserim ; on Taepo, 5000 feet, Gallatly ! Pegu ; on Tounkye- 

 ghat, Kurzw. 1709! 



A low spreading tree {fide Gallatly) hanging over streams. Leaflets very rigid 

 but not so thick as those of 8. crassifolius, with 6-8 pairs of almost straight, oblique 

 lateral nerves much raised on both surfaces, cross reticulations beneath very dis- 

 tinct ; shining above, dull beneath. Panicles a foot long, pedicels shorter than 

 calyx. Calyx '1 in. Corolla pink, '2 in. long, limb of standard hardly as broad as 

 long, emarginate at tip. Pod semi-transparent, finely downy, 3-5 in. long, '6 in. 

 across below, "3 in. wide at thickened apex. 



To this, owing to its having the same very distinctive calyx, the writer has 

 referred Mr. Kurz's n. 1709 (which formed part of Butea acuminata Kurz, not of 

 Wall.), although Mr. Kurz's specimen has not any leaves. By the leaves alone this 

 is remarkably distinct from any of the other Indian species of Spatholobus. Possibly 

 it may turn out to be the same as Pongamia rigida Grah. in Wall. Cat. 5908, which is 

 not at Calcutta ; should this prove to be the case the species must be known as 

 Spatholobus rigidus. 



6. Spatholobus Maingayi Prain, Journ. As. Soc. Beng. lxvi. 2. 

 79; leaflets thick and rigid, ovate-acute, rounded at the base, glabrous 

 beneath, flowers small, calyx adpressed brown-puberulous, teeth all 

 rounded one-third the length of tube ; pod unknown.

 10428! Scortechini 206 ! 1537! Wray 1270 ! Singapore; Ridley! 



Branches glabrous. Leaflets rather like those of 8. acuminatus but thicker, 

 shorter, quite glabrous, 3 in. long, 1'75 in. wide. Inflorescence in terminal and 

 axillary panicles 6-8 in. long. Pedicels shorter than calyx, bracts minute persistent. 

 Calyx "12 in. long. Corolla "25 in. long, standard orbicular very slightly emarginate.
