310 Rusby: An Enumeration of the Plants 



Urera rugosa sp. nov. 



Hispidity confined chiefly to the inflorescence : branchlets stout, 

 soft and weak, light brown : stipules about 7 mm. long, 4 mm. 

 broad, the body broadly ovate, with an attenuate acumination : 

 petioles 2.5-4 cm. long, very stout, vveak ; blades 1— 1.5 dm. long, 

 6-8 cm. broad, ovate or oval, rounded at the base, perfect apex 

 not seen, coarsely short-dentate, the teeth obscurely apiculate : 



leaf very thin, dark green above, bright green underneath, subtri- 



nerved, the venation inconspicuous above, prominent underneath, 

 the midrib and six to eight pairs of strongly ascending secondaries 

 dark purple, coarse, broad, nerved, connected by the straightish 

 tertiaries : panicles 1 dm. or more long, densely branched, droop- 

 ing, the rachis thick and fleshy, sparsely white -hispid : berries 

 nearly globose, 4 mm. long, tipped with the short and very stout 

 yellowish style. 



Unduavi, 8000 ft., Oct. 1885 (no. 1471). 



Urera filiformis sp. nov. 



Leaf-surfaces and inflorescence minutely grayish-puberulent : 

 branchlets stout, purple, terete : stipules 7-9 mm. long, purple, 

 ovate, long-acuminate, keeled : only the younger leaves seen, the 

 petioles 1 cm. long, broad, the blades 6-9 cm. long, 2.5-3 cm - 

 broad, oblong-ovate, rounded at the base, acute, sharply serrate- 

 dentate, thin, 3-nerved, the venation lightly prominent underneath, 

 the secondaries about 10 pairs, the venation coarsely reticulate : 

 panicles numerous, about 1 dm. long, consisting of few elongated, 

 filiform branches along which the very small flower-clusters are 

 rather densely disposed. 



Yungas, 6000 ft., 1885 (no. 1469). This seems to be the 

 same as E. P. Johnson's no. 97, from Tobasco, in Herb. Kew. 

 under U. microcavpa. 



Urera Rusbyi Britton sp. nov. 



Glabrous, except the minute puberulence on the lower leaf- 

 surfaces : branches coarse, deep purple, coarsely angled : stipules 

 not seen : petioles 2-4 cm. long, very slender : blades 1.25-2 dm. 

 l° n g. 5-7-5 cm - broad, oval, narrowed but blunt at the base, ab- 

 ruptly short-acuminate and obtusish at the apex, shortly crenate- 

 dentate, 3-nerved, the lateral nerves originating near the base, the 

 very slender and inconspicuous venation coarsely reticulate : 

 panicle shortly and stoutly peduncled, 2 or 3 dm. long and broad, 

 the branches very numerous and very slender, the flower-clusters 

 rather loosely disposed, the flowers nearly 3 mm. broad. 



Yungas, 6000 ft., 1885 (no. 1774).
