1 em. lonp,-, slender, channeled above. Blades to 3.;") by 1.5 cm., 

 lanceolate, mostly with acute base and obtuse sunmiit, entire, 

 thickish, the midrib and secondaries sharjjly prominent beneath, 

 the secondaries about 6 on each side, strongly ascending and 

 little curved. Cymes terminating the branchlets, mostly few- 

 flowered, dichotomous. Pedicels f) to 7 mm. long, filiform, re- 

 curved, tliickened upward and continuous with the calyx-tube. 

 Flower about 7 mm. long, the calyx nearly a third of the length. 

 Calyx campanulate-turbinate, the lobes about 1 mm. long and 

 broad, obtuse. Corolla bluish-white, pubescent, lobed nearly 

 half-Avay, the lobes ovate, obtuse. Stamens nearly equaling the 

 corolla, the filaments stout, flattened, two thirds the length of 

 the anther, which is oblong, straight, cordate at the base, trun- 

 cate, brown, completely dehiscent from the base to the pores, 

 which are rather large, looking inward and upward. Style 

 slightly exceeding the stamens, slender, nearly straight. Fruit 

 depressed-globose, 4 or 5 mm. broad. 



Pongo de Quime, 11,000 feet, 0. E. White, July 5, 1921 {no. 

 165). "A shrub 5 to 10 feet high, common in gulches, near 

 river. ' ' 



This very strange species well illustrates the aberrant ten- 

 dencies of the genera of this group. The habit of this shrub is 

 much like that of a Poecilochroma, with which it grows, as well 

 as with Solanum and Lycianthes. Its filament is that of Bas- 

 sovia, but its anther has distinct pores, as well as sutures. Its 

 openly cordate anther-base distinguishes it from any species of 

 any of these genera known to me. On the whole, I think it can- 

 not be separated from Solanum. 



Lycianthes subfalcata comb. nov. 



Brachistus suhfalcatus Eusby, Bull. N. Y. Bot. Gard. 8 : 117. 



Rurrenabacjue, 1,000 feet, M. Cardenas, November 25, 1921 

 {no. 1172). This collection, made just across the river from the 

 type locality, includes several partly developed flowers, from 

 which the following description is drawn. 



Calyx shallowly cupulate, 3 mm. broad, less than 2 mm. high, 

 gray-brown with 10 green nerves, the 10 teeth subequal, very 

 short, triangular. Corolla campanulate, 3.5 or 4 nmi. long, 

 deeply parted, the lobes thickish, ovate, obtuse. Filaments less 

 than half the length of the anthers, slender. Anthers 3 mm. long,
