* on paper,' in the " tardy dehiscence " of the pod in Millettia, its •' indehiscence " 

 in Pongamia and Derris. As a matter of f.ict Mr. Bentham has placed in Derris a 

 species (D microptera) the pods of whicli dehisce, while Mr. Knrz has placed in 

 Millettia a species (M. monticoln) that has the pods of a Derris. No taxonomist 

 however able, can venture in the absence of fruit to do more than suggest to which 

 of the three genera a particular species should be referred. A fourth o-enus to 

 which similar remarks apply is Lonchocarpus ; this only differs from ppecies of 

 Derris that have thin pods, exactly as Pongamia differs from species of Derris that 

 have turgid pods, in having sutures without wings. It is, moreover, a auspicious 

 fact that Koorders and Valeton (Bijdr. II,) find the same difficulty in separating 

 Pongamia from Millettia. 



In the works of Roxburgh and of Wight and Arnott, also in Bentham's account 

 of the Leguminosse in Plant. Jimghuhn., Millettia was not divorced from Derris and 

 its allies ; Miquel and Kurz, too, continued to place the genera side by side. And 

 certainly if tliey have adopted the less natural method of arrangement, it cannot be 

 denied that, in so doing, these authors have retained a much more convenient one.

Woody climbers witli unequally pinnately 1-7-foliolate exstipellate 

 leaves; stipules small, deciduous. Flowers rather small in am[)Ie ter- 

 minal thyrsoid panicles extending into the axils of the upper leaves ; 

 pedicels solitary, nodes not tumid. Ca/^.^ campanulate, teeth lanceolate 

 the two upper connate. Corolla distinctly exserted ; scnndard ovate 

 entire; keel boat-shaped tlie petals slightly cohering. Stamens diadel- 

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

 standard claw ; antliers versatile uniform on alternately short and lono- 

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

 capitate. Pod tliin flat strap-shaped membranaceops or coriaceous, 

 indehiscent, style terminal, sutures not winged. Seeds 1-3, mud) com- 

 pressed, oblong; radicle inflexed. Species 5, Malayan. 



This interesting genus possesses the habit of Spatholobus with tho calyx and 

 almost the corolla and stamens of that genus. It differs, however, in havino- its 

 flowers solitary in place of fascicled on tumid nodes ; in having exstipellate leaflets 

 varying in number in different species from 1-7; and in having the pod quite 

 indehiscent with the seeds centrally not terminally situated, in this last character 

 being indistinguishable from Lonchocarpus. From Lonchocarpus however Knnstleria 

 differs in having the flowers unfascicled, in having the calyx toothed, and in having 

 the stamens diadelphous. As regards inflorescence Kunstleria agrees exactly with 

 Derris § Aganope and agrees moreover with that group of species in havino- the 

 vexillary stamen free. But here again Knnstleria differs in having a wingless pod 

 and a toothed calyx, and in having tho free stamen adnate to the standard claw. 

 "With the calyx of Spatholohxis then, we have associated in Knnstleria the inflorescence 

 of Aganope and tho pod of Lonchocarpus. 



Tho genus is dedicated to tlie memory of Herr H. H. Kunstler, one of the most 

 enthusiastic, as he was one of the most painstaking and faithful of the collectors 

 who have laid down their lives in the cause of science in the tropics.
