BLAKE—REVISION OF RINOREA. 513 
has a very young inflorescence, with crowded subsessile flowers, while that 
of A. laziflora is mature and loose. The species as here taken is distinguished 
from Rinorea@ passoura chiefly by its externally glabrous petals and unap- 
pendaged or merely 1 or 2-setose anther cells. Bentham gives the number of 
ovules as 1 or 2 on the placentae; I have found them solitary in the only 
ovary dissected. The figure in Hooker’s Icones is a good illustration of the 
species, except that the leaves are represented as alternate. Dr. Stapf informs 
me, however, that they are opposite in the type in the Kew Herbarium, which 
is doubtless the specimen from which the figure was drawn. 
28. Rinorea deflexa (Benth.) Blake. 
Alsodeia deflera Benth. Bot. Voy. Sulph. 67. 1844. 
Branchlets and petioles hirtellous, glabrate; leaves opposite; petioles hirtel- 
lous, glabrate, 4 to 6 mm. long; blades oval-elliptic, 5 to 10 cm. long obtusely 
short-acuminate, rounded at base, obtusely dentate, submembranaceous ; 
racemes simple, 5 cm. long, hirtellous; pedicels 2 mm. long, deflexed ; sepals 
ovate, 2 mm, long, obtusish, thin, about 5-veined, ciliolate or ciliate, puberulous 
along midline; petals lance-ovate, 4.5 mm. long, narrowed to an obtuse apex, 
short-ciliate, otherwise glabrous; stamens 3.5 mm. long, the filaments 0.7 mm. 
long, somewhat exceeding the gland, the anthers 1.5 mm. long, shortly 1- 
mucronate or unappendaged, the connective scales elliptic-ovate, 2.8 mm. long, 
narrowed to an obtuse apex, obscurely erose below; ovary densely hispid- 
pilose, the placentae 1-ovulate. 
TYPE LocALITY: Atacames, Ecuador. 
SPECIMEN EXAMINED: 
Ecuapor: Atacames, Barclay (type collection ; a single flower, N). 
This description is compiled from the original, except for the characters 
of the flower, which are drawn from a single flower of the type forwarded 
by Dr. Otto Stapf, who states that the leaves are opposite. 
29. Rinorea ovalifolia (Britton) Blake. PLaTE 36. 
Alsodeia ovalifolia Britton, Bull, Torrey Club 16: 18. 1889. 
Branchlets densely hirtellous, tardily glabrate; leaves opposite; petioles 
densely hirtellous, 3 to 5 mm. long; blades oval or obovate-oval, 7 to 11 cm. 
long, 3.5 to 6 cm. wide, acutely short-pointed, at base cuneate to rounded, 
serrulate, papery, hirtellous on costa and veins above, beneath hirtellous on 
all the veins and veinlets; racemes 5 to 10.5 em. long, densely hirtellous, 
densely flowered; pedicels 2 mm. long, strongly deflexed ; sepals oval to orbic- 
ular-ovate, 1.6 mm. long, obtuse or rounded, ciliolate, more or less puberu- 
lous on back, not striate; petals ovate, 3.3 mm. long, narrowed to an obtuse 
reflexed apex, ciliolate above or glabrous; stamens 2.7 mm. long, inserted 
on the inner side of a short sparsely pilose disk, the filaments 0.3 mm. long, 
shorter than the triangular glands, the anthers 1.1 mm. long, unappendaged, 
the connective scales narrowly oblong-ovate, 2.4 mm. long, narrowed to an 
obtuse apex, glabrous, entire or obscurely erose; ovary and base of style 
densely hispidulous, the placentae 2-ovulate; capsule puberulous, 12 to 18 
mm. long; seeds solitary on the valves, about 4 mm. thick, glabrous. 
TYPE LOCALITY : Junction of the Rivers Beni and Madre de Diés, Bolivia. 
SPECIMENS EXAMINED: 
Bortvia: Junction of the Rivers Beni and Madre de Diés, August, 1886, 
Rusby 1916 (type collection; G, N, Y). 
This species is well marked by its oval hirtellous leaves and dense conic- 
cylindric racemes of very small, strongly deflexed flowers. The original de- 
scription of the leaves as glabrous is incorrect.
