 ^ Branch more than 10 in. long, dividing repeatedly, with many leaves, and flowers 

 from the lowermost as well as the upper axils. Leaves 2-3 in., cordate, ovate, very 

 unequal at the base, dentate-serrate, with very short viscid pubescence on both sur- 

 races; petiole ^~\ in., viscidly pubescent; stipules ^ in., ovate, acute, ciliate. Peduu" 

 ^« 2 m., few-flowered ; bracts ^ in,, ovate, acute, scarious, pubescent, persistent. 

 Mai^: sepals 2, \ in., round-elliptic; petals 2, narrower; stamens (ex A. DC.) mo* 

 nadelphous, anthers ovoid, connective not produced. Female : styles 3, free, each 

 ending in two long curved and twisted branches. Capsule J by § in. including the 

 ^ngs, at length glabrous, wings subequal, broadest near the base of the capsule, their 

 ^^rgin everywhere rounded. Seeds ellijwoid. — The locality of this plant is very 

 TOubtful. By Morung Hamilton understood the Terai from the river Teesta to the 

 ^ooshee (see Hamilton's Nepal p. 151): this tract has been explored by very good 

 collectors (J. Scott, Gamble, &c.) since, and no plant at all corresponding ta the pre- 

 sent large species has been obtained : indeed Alph. DC. doubts (and with reason) 

 whether any such plant has ever been found in Asia.

 continued all round the capsule, rounded altogether or having an obtuse angle at the
