tninate, much longer tlian the tube, the S upper ones only shortly united. 

 Petals scarcely exceeding, the calyx. Pod sessile, glabrous or minutely pu- 

 bescent, the upper suture straight or slightly indented, and often njore or less 

 dilated, the lower more deeply indented ; articles 2 to 4, thin, flat, with veiy 

 fine transverse reticulations, scarcely separating from each other aud some- 

 times perhaps opening on the lower edge.

 The species is common in India, extending over the Archipelago and into S. China. Thia 

 and B Muelleri seem to connect the section Sagotia^ founded on the common tropical J), 

 irifiorum^ DC, with B. hichostachyon and B.neurocarpmn^ which I have referred doubt- 

 fully to Heteroloma^ although they have the solitary pedicels of Sayotia. They all come 

 very near in habit to some of the looser-flowered species of the section Nicohonia, but the 

 pod is much less disposed to open on the lower edge.

Calyx 2 upper lobes united into one. Standard nearly orbicular, narrowed 

 at the base ; wings adhering to the keel ; keel obtuse, with small lateral 

 appendages. Upper stamen free or at fii'st united with the others, anthers 

 uniform. Ovary sessile, with several ovules. Style subulate, with a terminal 

 stigma. Pod oblong, turgid, 2-valved, transversely veined. Seeds several, 

 not strophiolate.— An undershrub, with the habit of Demodium. "Leaves 

 pinnately 3-foliolate or 1-foliolate, with stipelfe. Flowers small, in terminal 

 racemes or panicles. 



The geuus consists of a single species, extending over the Indian Archipelago to S. Cliiua, 

 It is very nearly allied to Besmodiam, escept in the pod (nearly that of Crotalam),'^'^^^^^^ 

 would technically remove it from Uedf/mreie, hut it has no immediate affinities iQ auy 

 other tribe.
