This species may be distinguished by its small flowers, erose connective 
scales, apically unappendaged anthers, and very short filaments with the 
glands apical. The bent style is apparently peculiar to this and &. lindeni- 
ana, Pennell gives the vernacular name as “ jazmin,”’ Jahn as ‘“ tabaquito,” 
and Pittier as “ rabo de cachicamo.” At first I considered all the material above 
cited to represent a new species, and labeled it with a manuscript name, but 
information as to Aublet’s type communicated by Mr. E. G. Baker makes it 
fairly certain that the species described is the hitherto misunderstood Riana 
guianensis of Aublet. 
Kichler’s Alsodeia guianensis var. parviflora,” based on Kappler 2111, from 
Surinam, may be referable to this species, but the description is insufficient. 
EXPLANATION OF PLATE 32.—Rinorea riana, from Pittier 8908. Natural size. 
14. Rinorea micrantha Ule, Verh. Bot. Verg Brand. 47: 157. 1905. 
Shrub or tree, 3 to 15 meters high, the branchlets sparsely pilosulous; leaves 
opposite; petioles 3 to 6 mm. long; blades oblong, 13 to 15 cm. long, 5 to 7 cm. 
wide, long-acuminate, usually slightly cordate at the oblique base, crenulate or 
serrulate, glabrous; panicles racemiform, 9 cm. long. pilosulous, the lower 
branchlets about 4-flowered; sepals elliptic, 1 mm. long, ciliolate; petals ovate- 
elliptic, 2 mm. long, ciliolate; stamens 1.5 mm. long, the filaments bearing a 
subulate gland at base, the connective scales ovate, erose, nearly twice as long 
as the anthers; ovary densely pilose, the placentae 1-ovulate. 
TYPE LOCALITY: Upper Rio Jurué, at Bocca do Tejo, Province Amazonas, 
Brazil. Type collected by Ule (no. 5477). 
Not seen; description compiled from the original. Ule apparently con- 
sidered the presence of staminal glands a new feature in the genus, but they 
are obvious in nearly every American species. 
15. Rinorea hymenosepala Blake, sp. nov. PLATE 33. 
Shrub; branchlets sordidly incurved-puberulous, glabrescent; leaves oppo- 
site or alternate; petioles incurved-puberulous, 2 to 6 mm. long; blades some-
