nearly orbicular, 3-ribbed at base and finely many-nerved. Sta- 

 mens 9, equal, distinct, shorter than the petals, the filaments 

 stout and fleshy, slightly broader downward, concave or chan- 

 neled on the inner side, the anthers a])out half as long as the fila- 

 ments, ^^'ith blunt blackish terminal glands. Pistil as long as the 

 stamens, the ovary oval, with a sessile, discoid, thick stigma two 

 thirds as broad as the ovary. 



A handsome shrub, 4 to 6 feet high, on sunny l)anks at Pongo 

 de Qui me, 11,500 feet, 0. E. White, July 12, 1921 {no. 169). 



Mexispermaceae 



Cissampelos violaefolia 



Pubescent, with the upper leaf-surfaces subglabrous except 

 on the principal veins. >Stems slender, terete, densely short- 

 pubescent. Petioles 5 to 8 cm. long, slender, channeled above, 

 the blades 3 to 6 cm. long, 3.5 to 7 cm. broad, subrotund, cordate, 

 the summit subemarginate and minutely apiculate, entire, 

 thickish, rigid, deep-green above, pale beneath, the venation 

 prominent on both sides, especially beneath, strongly and very 

 finely reticulate, 7- to 9-ribbed, the ribs all originating together 

 at the summit of the petiole. Racemes 7 to 10 cm. long, the 

 rachis stoutish, the bracts similar to the leaves, 1 to nearly 2 cm. 

 broad, conspicuously and finely purple-veined, short-petioled. 

 Flowers (only the pistillate seen) in fascicles of 6 to 10, on 

 slender pedicels which are mostly longer than the petioles of the 

 bracts. Calyx persistent, in fruit subrotund, entire, about 7 mm. 

 broad and about twice as broad as the brown tuberculate fruit. 



Ixiamas, 800 feet, M. Cardenas, December 20, 1921 {no. 2015). 



Cissampelos ciliata 



Stems, jDetioles, etc., sparsely pilose with long, white, diver- 

 gent hairs, the leaf-surface sparsely strigose ^^'itll similar hairs. 

 Stems very slender, strongly 5-sulcate. Petioles 3 to 6 cm. 

 long, strongly grooved on the upper surface, peltately at- 

 tached about one fourth of the way from the base of the leaf. 

 Blades 5 to 10 cm. long, and about as wide, ovate, with broad, 

 nearly truncate base and obtuse but setose summit, entire, cili- 

 ate, thin, pale-green, especially beneath, the venation slender, 

 coarsely reticulate, radiately 10 to 12-nerved, the ultimate 

 branches of the nerves terminating in the margin. Staminate 

 panicles fascicled, 3 or 4 cm. long, the peduncles and branches
