sinuses 3 mm. wide; corolla white or pale yellow, 38 mm. long 

 over all, the tube 15 mm. long, upper four lobes 23 mm. long, 

 straight and erect, narrowly triangular, 2-3 mm. wide at the 

 base, the lower lobe linear, separate nearly or quite to the base; 

 anther-tube 11 mm. long, about equaling the petals, glabrous, 

 all anthers densely woolly at the apex. 



Type, Matthews ii8j, collected in Peru, and deposited in the 

 herbarium of the Royal Botanic Garden at Kew, England. 



S. corynellus is closely akin to 5. corynoides Wimmer, of which 

 I have seen a sheet collected by Pearce and Cook & Gilberi 1326. 

 The two are at once distinguished from the other species of the 

 genus with short corolla-tube and pale flowers by the corolla, in 

 which the lower lobe is separate from the others almost to the 

 base.

 45~75 mm. long, 15-25 mm. wide, or the upper smaller, acute or 

 short-acuminate, broadly cuneate at base, finely and sharply 

 fimbriate-denticulate with triangular-subulate, callous, salient 

 teeth (about 20 teeth per cm. of margin, 0.3-0.8 mm. long), dull 

 green, rugose, and minutely puberulent above, pale green and 

 densely hirtellous with nearly straight white hairs beneath ; 

 lateral veins 2-5 mm. apart, ascending at an angle of about 45° 

 and freely branching in their distal half, the veinlets finely 

 reticulate; peduncles numerous, axillary, forming a leafy ter- 

 minal raceme, 25-45 mm. long, densely white-hirtellous, fre- 

 quently twisted or contorted 6 mm. from the summit; bracteoles 

 filiform, 3 mm. long; hypanthium broadly turbinate-pyriform, 

 6-8 mm. high, 7-9 mm. wide when pressed, prominently 10- 

 ribbed, minutely white-hirtellous; sepals erect or slightly spread-

 nerved, conspicuously white-hirtellous; corolla 4 cm. long over 

 all, red above, yellow on the ventral half, minutely and sparsely 

 pubescent, the tube 22 mm. long ventrally, 26 mm. dorsally, the 

 lobes linear, the lower 18, the upper 14 mm. long; stamens about 

 equaling the corolla, the filaments glabrous, the anther-tube 

 glabrous, greenish-brown, 7 mm. long, the two lower anthers 

 penicillate.
