46-4 D. Prain — Some additional Leguminosa?. [No. 2, 



Derris ovalifolia Benth. 

 The only S. Indian plant in the Calcutta Herbarium that agrees with the figure 

 given by Wight is that distributed from Wight's herbarium as n. 834 [K. D.] This 

 in turn suits very well the description given of D. Wightii Baker. 



Derris discolor Benth. 



This, as has been already mentioned, is almost certainly merely that state of D. 

 cuneifolia with ripe fruits. 



89* KUNSTLERIA Prain. 



Climbing shrub with unequally pinnately 1-7-foliolate exstipellate 

 leaves, stipules small deciduous. Flowers rather small in ample termi- 

 nal thyrsoid panicles extending into the axils of the upper leaves, 

 pedicels solitary, nodes not tumid. Calyx campanulate, teeth lanceolate, 

 the two upper connate. Corolla distinctly exserted, standard ovate 

 entire, keel boat-shaped, the petals slightly cohering. Stamens diadel- 

 phous, the upper one quite free from the other 9 and adnate at base to 

 standard-claw ; anthers versatile, uniform, on alternately short and long 

 free filaments. Ovary sessile, few-ovuled, style incurved filiform, stigma 

 capitate. Pod thin flat strap-shaped, membranous or coriaceous, inde- 

 hiscent, style terminal, sutures not winged. Seeds 1-3, much compressed, 

 oblong, radicle inflexed. Species 5, Malayan. 



This genus has the habit of Spatholobus with calyx and almost corolla and 

 stamens of that genus. It differs, however, in having solitary not fascicled flowers 

 and in having exstipellate leaflets as well as in having a pod indehiscent throughout, 

 with its seeds centrally not terminally situated, and thus not distinguishable from a 

 Lonchocarpus pod. From Lonchocarpus, however, Kunstleria differs in having the 

 flowers unfascicled, in having the calyx deeply toothed and in having the vexillary 

 stamen free. As regards inflorescence Kunstleria repeats the characters met with 

 in Derris § Aganope with which it further agrees in having a free upper stamen. 

 But from Aganope, Kunstleria differs in having a wingless pod, a deep-toothed calyx, 

 and in having the free stamen adnate to the claw of the standard. 



The calyx characters suggest that the natural place for the genus might be in 

 Phaseolese along side of Mastersia, but the absence of stipels and the fact that the 

 leaves may be 5-7-foliolate, together with the rather marked affinities as regards pod 

 with Lonchocarpus and as regards inflorescence with Aganope, seem to render it more 

 advisable to place it in Dalbergiese beside Lonchocarpus and Derris.
