MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 



Pourouma subtriloba 



(Only fruitino: specimen seen.) Shortly soft-tomentose, ex- 

 cept the scabrous upper leaf-surfaces, the branchlets dark-fer- 

 ruo-inous, striate, very slenderly obliquely annulate at the top 

 of the leaf-scar, which is about as broad as long. Petioles stout, 

 striate, ferruginous, less than half the length of the blades, which 

 in my specimens are from 10 to 20 cm. long, 7 to If) cm. broad, 

 ovate, the largest somewhat 3-lobed, lightly cordate at the base, 

 acute or acutish, entire or very obscurely sinuate-crenate, thick, 

 deep-green and scabrous above, white and soft-tomentose be- 

 neath, the secondaries slender, straightish, at an angle of about 

 45 degrees, connecting very near the margiji with the tertiaries, 

 by several loops, connected by innumerable tertiaries, between 

 which the veins strongly anastomose. Fruiting cyme (but one 

 seen) small and few-fruited, stoutly jieduncled, the fruits shortly 

 and stoutly pedicelled, subtended by a rotate, entire, thick calyx- 

 base 6 mm. broad, subglobular, nearly 2 cm. long and broad. 



Near Tumapasa, 1,500 feet, M. Cardenas, December 10, 1921 

 (no. 1990). "A large forest tree with edible fruit." Very near 

 Hayes, Panama, no. 860, which appears to be undescribed. 



Urticaceae 



Urera viridisetosa 



Stem densely clothed with si^reading or slightly retrorse 

 prickles which are 3 to 5 mm. long, linear, green, terminating 

 in a white seta, and the upper part of their margins 



minutely white-setose. Stipules connate, 10 to 15 mm. long, 

 ovate, with attenuate smumit. Prickles of the petioles and veins 

 of the lower leaf-surfaces reflexed, on successively shorter green 

 bases. Petioles about a third of the length of the blades, which 

 are 1 to 2 dm. long, 5 to 10 cm. broad, ovate, acute, slightly cor- 

 date, coarsely dentate, both teeth and sinuses short, triangular, 

 acutish ; thin, the upper surface deep-green and irregularly pap- 

 illose, the lower surface pale or grayish-green, tomentose, finely 

 reticulate. Cymes scattered along the sides of the stem, one or 

 two cm. long. Pistillate tioAvers prickly, the stigma densely jjilose. 

 Fruit 2 mm. long, subglobose. Staminate flowers not seen. 



Huachi, 1,800 feet, 0. E. White, September 4, 1921 {no. 1010). 

 "A shrub, 6 to 8 feet high. Prickles worse than those of 

 Jatropha."
