500 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
physiphora Mart. was given as a synonym), C. castanaefolia, and C. rinorea. 
The racemes in the first two species were described as simple, resembling 
those of the lily-of-the-valley, and the leaves as crowded at the tips of the 
branchlets. The third species, Conohoria rinorea, was described as with 
compound racemes and alternate, rather remote leaves, and to its synonymy 
were referred Rinorea guayenensis [sic] Aubl. and Alsodea paniculata Mart. 
Eichler himself refers this third name of St. Hilaire (Conohoria rinorea) 
to his own A. castaneaefolia, a species characterized by its paniculate flowers, 
scattered (not crowded) leaves, and petals considerably longer than the se- 
pals. Conohoria castanefolia, described as with simple racemes and leaves 
crowded at the tips of the branches, is considered synonymous. This course 
is contrary to St. Hilaire’s description; and since he showed a clear appre- 
ciation of the characters of most significance in this group, it seems neces- 
sary to follow his descriptions rather than the views of Eichler. The differ- 
ences between C. lobolobo and C. castanaefolia indicated by St. Hilaire do not 
seem to be of any real consequence, and both are described from the vicinity 
of Sao Sebastifio, so that their reference to the synonymy of Rinorea physi- 
phora seems justified. 
I have not been able to find any difference of importance indicated by the 
description of R. guianensis, when compared with an authentic specimen 
of Alsodeia floribunda Moric., and Mr. E. G. Baker, who has compared the 
still existent type of Aublet’s species with material of A. floribunda which 
I sent him, has likewise not discovered any difference between them. Con- 
sequently, in spite of the considerable gap in the ranges as now known, the 
two names are here considered to refer to one species.

mm. long; blades oblong-obovate, rarely elliptic-obovate, 8 to 13.5 cm. long, 
2.5 to 5 em. wide, short-pointed with obtuse mucronulate apex, rounded at

green, minutely hirtellous beneath along the costa and the 5 or 6 pairs of 
lateral veins, prominulous-reticulate on both sides; panicles axillary, 1 to 3,

united glands of the filaments?), the free portion of the filaments slender, 0.4 
mm. long, the anthers roundish, 0.8 mm. long, sometimes bearing at apex 1 or 2 
ligulate appendages 0.4 mm. long or less, the connective scales oblong-oval, 1.7

Readily distinguished among North American species by its alternate leaves, 
paniculate inflorescence, and glabrous ovary.
