Canamina, 4,000 feet, 0. E. White, July 28, 1921 (no. 408). 

 "A spreading tree, 10 to 18 feet high, growing in damp shady 

 ravines, associated with Bocconia." 



Solanum sassafrideum 



Apparently nnarmed; densely and shortly ferruginous- 

 tomentose, the tomentum interspersed with longer straight or 

 curved coarse whitish stiff hairs, which also occur on the mid- 

 rib of the upper leaf-surface, which is strongly and harshly 

 muricate. Branches and branchlets short, veiy stout, terete. 

 Only the upper leaves seen, there probably being others, much 

 larger. Petioles 4 or 5 cm. long, 4 or 5 mm. thick. Blades 

 broken in my specimen, and their characters imperfectly dis- 

 played. They are about 1.5 dm. long and nearly as A\-ide, obo- 

 vate, with cordate base, its sinus narrow, the summit not seen ; 

 margin unequally and irregularly lobed, the lobes blunt or ob- 

 tuse, sometmies narrowed toward the base; leaf thick, above 

 deep-green and somewhat ferruginous, harshly papillose, be- 

 neath grayish-ferruginous and densely short-tomentose, the 

 principal veins coarse and prominent. Principal secondaries 7 

 or more, at an angle of about 45 degrees, nearly straight, with 

 numerous smaller intermediate ones, which are divaricate. 

 Cyme terminal, dichotomous, broad, densely flowered at the ends 

 of the branchlets. which are deeply ferruginous-tomentose, 

 marked with whitish depressions from the fallen pedicels, which 

 are very short and stout. Mature bud 1 cm. long and half as 

 broad, nearly ellipsoid. Cah^x-tube between erateriform and 

 hemispheric. 4 mm. wide, 5-ribbed. the teeth triangular-subulate, 

 longer than the tube, acute, keeled. Corolla tomentose. on both 

 surfaces, Avhitish, rotate, nearly 2 cm. broad, lobed two thirds of 

 the way, with plicate folds in the sinuses, the lobes ovate, obtuse, 

 3-nerved. the margins involute. Filaments extremely short, the 

 anthers deep-purple, slightly unequal, about 6 mm. long, oblong 

 or a little narrower above, obtuse, the pores whitish, looldng in- 

 ward and laterally. 



Pongo de Quime, 11,5U0 feet, U. E. White. July 12, 1921, {)io. 

 156 ). "A smaU tree, 12 to 15 feet high, with white flowers, grow- 

 ing in full sunshine." 



Solanum pongoense 



Unarmed, the young leaves very minutely puberulent. ^luch 

 branched, the branchlets short, stout, somewhat angled when 

 young. Leaves very unequal, the petioles of the larger ones to
