 proliferous, or the peduncle going off into a runner. Leaves 1-1 J by 1-1^ in., nearly 

 glabrous, obscurely acuminate, obtuse at the apex, base equal or unequal ; petiole \ in. ; 

 stipules small, ovate, glabrous. Peduncle weak, terminal, dichotomous, lajc, slightly 

 glandular-pubescent. Flowers small (white ex Kurz). Mat.k ■ sepals 2, obovate, 

 glabrous or with few paleaceous hairs ; petals 2, much smaller ; stamens mona- 

 delphous, about 8, anthers obovoid, connective apiculate, but not produced. Frwat.r : 

 perianth-segments 5 ; ovary 3-eelled, glabrous, placentas bipartite {Kwrz) ; styles 3, 

 nearly distinct, divided only near the top, stigmas lunate. Capsule less than J by

15. B. modestiflora, Kurz in Flora 1871, 296; caulescent, infloies- 

 cence terminal elongate and panicled in fruit, leaves ovate-acuminate from a

Glabrous or nearly so. Bootstock tuberous. Stem erect, sometimes a foot. 

 Leaves 3—4 by 2 in., not lobed, caudate-acuminate, base very unequally cordate or 

 very obliquely subtruncate ; petiole 1^-2^ in. ; stipules sn^, lanceolate. Oymes 

 elongate, narrow, slightly panicled ; bracts small, lanceolate, ciliate, caducous ; 

 flowers numerous, small, white. Mat.b : sepals 2, petals 2, smaller ; stamens (about 

 12), free ex Kurz (distinctly monadelphous ex Parish), anthers obovoid, connective 

 slightly produced in a triangular point. Femat.b : perianth-segments 6, much en- 

 laced in fruit; ovary glabrous, 3 -celled, placentas 2-partite; styles 3, nearly distinct, 

 broader upwards, stigma lunate. Capsule rather more than J by 1 in. including 

 the wings ; styles deciduous ; 3 wings prominent, their upper margins horizontal, one 

 often very greatly produced ; capsule dehisdng by the three faces. Seeds short- 

 «llipspid. — ^Kurz placed this species next iS. setctata, but the 5 female perianth seg- 

 ments refer it to Knesebeckia proper, and not to Trilobaria, A. DC. Possibly two 

 species are mixed here. Wallich's very immature specimen has exceedingly small 

 flowers and weak inflorescence and is referred by Meissner in ms. to B. hydropkUa.
