Shrub or small tree; branches puberulous and hispid-pilose; leaves opposite ; 
petioles 5 to 10 mm. long; blades oval to elliptic, 8 to 17.5 cm. long, 3 to 8 cm. 
wide, short-pointed to acuminate, at base rounded to cuneate, obscurely crenate- 
serrulate or subentire, puberulous on costa above, sparsely hispid-pilose on 
costa and sometimes on veins beneath; racemes 3.5 “to 10” cm. long, densely 
ferrugineous-puberulous, the pedicels about 4 mm. long; sepals broadly ovate 
or orbicular-ovate, 1.8 to 2 mm. long, obtusish, strongly several-ribbed, ciliolate, 
on back rather densely pilosulous and more or less puberulous; petals oval- 
oblong, “ white or yellow,” 4.2 to 5.5 mm, long, obtuse, scarcely narrowed to- 
ward apex, very shortly reflexed, pilose along midline with erect rufidulous 
hairs, ciliolate near apex; stamens 3.1 to 3.8 mm. long, the filaments 0.8 to 1 
mm. long, equaling or exceeding the oblong gland which is free above the 
middle, the anthers 1.3 to 1.5 mm. long, 1 or 2-cuspidate or 2 to 4-setose at 
apex, the connective scales oblong-ovate, 2.3 to 2.6 mm. long, obtuse, obscurely 
erose ; ovary densely hispid-pilose, the placentae 2 or 3-ovulate; “capsule 2 to 
3 cm. long, tomentose, glabrate; seeds 3 to each placenta, velvety-tomentose.”

(fruit, seed). 
TyPE Locality: Forests of Timoutou, French Guiana. Type collected by 
Aublet. 
SPECIMENS EXAMINED: 
CoLoMBIA; Between Villavicencio and San Martin, basin of the Rfo Meta, 
altitude 250 meters, Triana (Y). 
BRITISH GuIANA: Banks of rivers, Schomburgk 573 (type of A. pubi- 
flora; a single flower examined, N). Without definite locality, 1834, 
Schomburgk 119 in part (N), 336 in part (N, Y). 
This species was originally described by Aublet from fruiting material. 
De Candolle united Conohoria flavescens Aubl. and Passoura guianensis under 
the name Conohoria passoura, indicating by a sign of affirmation that he had 
seen authentic material of the former but not of the latter name. I have 
followed Kichler in his interpretation of the species, but not in all his reductions. 
Alsodeia pubifiora, known to me only by a single flower from the type forwarded 
by Dr. Otto Stapf, I was at first inclined to consider a distinct species, having 
found the anther cells about 4-setose with filiform setae at apex, while in 
“ichler’s A, guianensis (R. passoura) they were described as like those of 
A. falcata, that is, 1 or 2-cuspidate. In a single flower of Schomburgk’s no. 336, 
however, I found anthers with 2 or 8 filiform setae or with a single linear- 
lanceolate cusp passing at apex into three filiform setae, showing that Eichler’s 
reduction of this species is correct. On the other hand, A. lindeniana Tulasne, 
considered a variety by Hichler, is certainly a very distinct species, having, 
unappendaged anthers, racemo-paniculate flowers, small petals, and solitary 
ovules. Alsodeia brevipes and A. laziflora, treated as independent varieties 
by Eichler, I consider inseparable from one another but specifically distinct 
from the Alsodeia guianensis described by Eichler. Eichler’s var. parviflora 
is unknown to me. Alsodeia flavescens, as described and figured by Oudemans™ 
(but not Conohoria flavescens of Aublet), is also referred by Eichler to his A. 
guianensis, but from the description of the petals as little exceeding the sepals
