A single specimen collected in Bolivia on the Mulford Ex-

CUCURBITACEAE 



Gurania plumosa 



(Staminate plant.) Pilose throughout with long soft white 

 hairs. Stems elongate, slender, green, deeply sulcate. Petioles 

 about a fourth the length of the blades, their white shining hairs 

 divaricate, like those of the stem, peduncles, etc. Blades vary- 

 ing from 20 cm. long and 14 cm. broad to 16 cm. long by 15 cm. 

 wide, cordate with rounded sinus and lobes, the base slightly 

 produced into' the sinus. Broader leaves tending to be slightly 

 3-lobed, the others ovate, the summit abruptly contracted into a 

 finely attenuate point 2 or 3 cm. long. Margin strongly ciliate 

 and armed with scattered teeth which are reduced to very small 

 divaricate points. Upper surface deep-green, rather sparsely 

 clothed with the hairs described above, the lower surface gray- 

 green, more densely clothed in the same way. Leaves 3- to 5- 

 ribbed, the ribs lightly prominent, slightly keeled or 1- to 

 3-nerved, the remaining venation loose and weak. Peduncle 

 slender, its length not determined, l^earing a swollen point or 

 articulation below the flowers, which are densely capitate, the 

 calyx beautifully clothed throughout with very long, white, and 

 shining divaricate hairs. Calyx-tube 6 mm. long, nearly 4 mm. 

 broad, the teeth somewhat unequal, to 3 cm. long, of setaceous 

 form. Petals less than half the length of the calyx-teeth, thick 

 and rigid, somewhat recurved, somewhat united at the base. 

 Stamens 5 mm. long, the anthers 3 mm. long, white, oblong. 



Tumapasa, 1,000-1,500 feet, 0. E. White, December 6, 1921 

 {no. 1827). "A vine, 15 to 20 feet long, on a tall tree in damp 

 shady sandy loam. Calyx scarlet-orange, the corolla yellow. 

 Juice not milky." Species very near G. Andreana Cogn. 



Gurania annulata 



(Pistillate plant.) Finely and closely tomentellate. Stems 

 elongate, slender, sulcate, reddish, sparsely puberulent. Peti- 

 oles somewhat shorter than the leaves, flattened, costate, twisted, 

 dilated at the base, strongly channeled by the upturned margins. 

 Blades 1.5 dm. long and a little l)roader, broadly cordate, 3-lobed. 

 Base of blade triangular, a little wider than long, meeting the 

 petiole slightly higher than the bases of the broadly rounded
