 varicate. Blades to 1 dm. long and 4 cm. broad (the lower prob- 

 ably larger), lanceolate to oblanceolate, acmuinate at botli ends, 

 acute, sparingly sinuate-dentate, the teeth small, triangular, di- 

 rected outward, very thin, deep- but dark-green, nearly glabrous 

 above, sparsely and very shortly stellate-hairy beneath, where 

 the slencler venation is lightly prominent, the secondaries about 

 8 or 10 on each side, strongly ascending except at the erect ends. 

 Inflorescence terminal, pseudo-racemose or paniculate, small, 

 few- to many-flowered, the rachis nodose from the fallen flowers. 

 Pedicels to 2 cm. long, nearly filiform, upAvardly thickened. 

 Calyx-tube nearly hemis])herical, 1.5 nnn. broad, the lobes 4 mm. 

 long, subulate, acute. Corolla nearly 1 cm. long, puberulent, ap- 

 parently white, divided nearly to the base. Filaments ver>^short. 

 Anthers regularly acuminate from the base, the longest 7 mm., 

 the shortest 5 mm. long, the pores looking upward and a little 

 inward. 



Near Lake Rogagua, 1,000 feet, H. H. Rushy (probably as a 

 part of no. 827). 



Solanum canaminense 



Armed with scattered very small yellow shining strongly re- 

 curved prickles which are pungent and slightly flattened later- 

 ally, densely soft-tomentose Avitli gray or yellowish hairs. 

 Branches elongated and stout, somewhat flexuous, terete. Peti- 

 oles 2 to 5 cm. long, recurved-spreading, stout, bearing a few 

 prickles, as does the midrib underneath. Blades 12 to 20 cm. 

 long by 4.5 to 8 cm. broad, oval-ovate, Avitli obtuse or acute base 

 slightly produced into the petiole and obtuse or acutish summit, 

 entire, thickish, deep-green above, with straight Avhite hairs 

 amidst the matted darker ones, paler beneath, with the slender 

 venation conspicuous, crooked and coarsely anastomosing, the 

 secondaries 7 to 10 on each side, strongly falcate-ascending. 

 Cyme terminal, small, dense, branching. Pedicels 5 to 8 mm. 

 long, very stout. Mature bud 12 to 15 mm. long, 5 mm. wide, 

 the calyx two third of the length, the corolla obtuse, angled. 

 Calyx-tube crateriform, 5 mm. wide, the lobes linear-attenuate. 

 Expanded corolla deep-purple, nearly 3 cm. wide, subrotate, 

 densely long-pilose, deeply lobed. Stamens equal, two thirds as 

 long as the corolla, the anthers regularly lanceolate, straight, 

 the pores elongate, looking inw^ard, and a little upward. Style 

 exceeding the stamens, the summit incurved. Fruit not seen.
