92 New Species of South American Plants 



ish and rigid, 3 mm. long, the anthers exserted and partly 

 covered by the converging ligules. 



"Twining to 6 feet. Rare in forest near Masinga, 250 to 

 500 feet. Flowers November to December, the corolla pale 

 greenish-yellow. Collected November 18." (Herbert H. Smith 

 No. 1644.) Also at Bonda, October 23. 



Species very near to Eggers No. 5568. 



Hemipogon (?) andinum. 



Glabrous, the stems somewhat woody, erect or ascending, 

 the branches erect, 3 or 4 dm. high, slender, densely leafy. 

 Leaves 3 or 4-verticillate, 5 to 10 cm. long, acerose, sharply 

 .3-ribbed beneath and channelled above, acute, erect. Peduncles 

 lateral 3 or 4 mm. long, stout, erect, angled, I to 3-fiowered. 

 Pedicels shorter than the peduncle, erect, stout, sharply angled, 

 bracteolate at the base. Flower 3 mm. long, erect. Calyx 

 parted nearly to the base, the lobes a third or a fourth the 

 length of the corolla, ovate, acute, thickish. Corolla-tube 

 shorter than the limb, urceolate, inflated, obscurely angled, 

 broader than long, the lobes erect, lance-linear, acute. Pod 

 2.5 to 4 cm. long, 6 to 8 mm. wide, stoutly lanceolate with some- 

 what contracted base and acuminate summit, brown, finely 

 striate. 



"Santa Ana, Bolivia, 5,500 feet altitude, July 31, 1902." 

 <R. S. WiUiams, No. 1589.) No. 113, "From hillsides near 

 Apolo, February 20", is apparently the same, with somewhat 

 shorter leaves and pods. 



I am very doubtful as to the generic affinity of this and the 

 following species, but they appear more closely allied to this 

 than to any other described genus. 



Hemipogon (?) Williamsii. 



Glabrous, the stems erect or ascending, 3 or 4 dm. high, 

 slender, erect-branching, very leafy, the leaves opposite or in 

 threes, 3 to 8 cm. long, narrowly linear, acute, erect, strongly 

 nerved. Peduncles 3 mm. long, stout, angled, ascending, 

 mostly 3-flowered, bracted at the summit. Pedicels shorter 

 than the peduncles and similar to them, erect, stout, angled. 

 Flowers about 5 mm. long, two-thirds as broad, yellowish-green, 

 somewhat fleshy. Calyx parted nearly to the base, the lobes 

 about I mm. long, ovate, acute, hyaline, not glandular within. 

 Corolla-tube urceolate, inflated, obscurely angled, the limb 

 nearly as long, 5-parted, the lobes erect and connivent, lance- 

 olate, acute. Crown adnate, to the corolla-tube, its margin 

 free in the throat, forming a thickened ring, which is short and 

 irregularly sinuately lobed. Filament- tube shorter than the
