Root-leaves to 2 or 3 cm. long, inohidinf? tlie long petiole, widely 

 spreading, prostrate or ascending, the blade 4 to 10 mm. or more 

 long, the base tapering into the petiole, thickish, entire, obtuse. 

 Stem-leaves few or none, sessile, lanceolate, to 1,5 or 2 cm. long, 

 yellowish-green, with a stout green midrib. Flowers solitary at 

 the ends of the stout branchlets, all parts persistent. Calyx- 

 lobes 5 mm. long, nearly 2 mm. wide, oblanceolate or spatulate 

 with rounded summit, erect. Corolla-tulies 5 mm. long, erect, 

 lanceolate, acutish, the spur of equal length, com])leteIy reflexed. 

 Stamens nearly 2 mm. long, erect, filament and anther about 

 equal, or the filament longer, the filament slender, somewhat 

 flattened, the anther oval, extrorse, attached at about the middle. 

 Pod nearly 1 cm. long, 4 mm. broad, ovoid, acute, 2-valved. 



Pongo de Quime, 11,500 feet, 0. E. White, July 11, 1921 {no. 

 178). "Herb 4 to 6 inches high, in sandy loam, by water edge, 

 in boggy ground. Flowers greenish to yellowish. Rare." 



Chelonanthus Whitei 



Glabrous, the stems 1 to 2 meters high, erect, terete, simple, 

 or nearly so, the inflorescence successively bifurcating, the 

 branches approximate and erect, many-flowered. Leaves 5 to 

 9 cm. long by 3 to 5 cm. broad, obovate, entire, acute, gradually 

 narrowed into a petiole-like base, very thin, a pair of strong, 

 coarse, strongly ascending secondaries arising some distance 

 above the base, with a variable number of smaller ones above, 

 the remaining venation weak and scanty. Pedicels stout, shorter 

 than the calyx, reflexed in fruit. Calyx cupulate or campanu- 

 late, nearly 1 cm. long and nearly as broad, as pressed, deeply 

 5-lobed, thick and fleshy, the lobes subequal, broadly ovate, ob- 

 tuse, with a very short, stout acute terminal point. Corolla ab- 

 ruptly expanded on emerging from the calyx into a campanulate, 

 strongly two-lipped limb, the shorter lip extending 1.3 cm. 

 beyond the cah-x, its margin sharply reflexed, the longer extend- 

 ing more than 2 cm. beyond the calyx, its middle lobe nearly 

 twice the length of the lateral. Stamens and style slightly ex- 

 serted, the anthers broad, minutely muticous, the style stout, 

 its linear branches a fifth of its total length. 



Ixiamas, 800 feet, 0. E. White, December 16, 1921, {no. 1195). 

 "Growing in full sunshine, on open pampa, the flowers green- 

 ish-yellow." Species near C. acutangula (R. & P.) Gilg, but the 

 stem not angled, the calyx larger and the corolla of different 

 form.
