ucuminate, at base acutely cuneate, remotely and obscurely serrulate, papery, 
glabrous on both sides or obscurely strigillose on costa beneath ; racemes about 
8 cm. long, sordid-puberulous, the pedicels deflexed, 3 mm. long; sepals oval or 
oval-ovate, rounded, 1.6 to 2.3 mm. long, ciliolate, along midline somewhat 
puberulous or subglabrous; petals “ yellow,” elliptic-ovate, 4 mm. long, obtuse, 
reflexed at apex, glabrous; stamens 3.2 mm. long, the filaments 0.7 mm. long, 
usually much longer than the basal gland or rarely equaled by it, the anthers 
1.2 mm. long, 2-cuspidate, the connective scales ovate, 2.56 mm. long, obtuse, 
somewhat erose below; ovary densely pilose, the placentae 2-ovulate; “ capsule 
2 cm. long, glabrate; seeds 2 to each valve, glabrous.” 
TYPE LOCALITY: Forests along the Rio Yapura, Province of Alto Amazonas, 
Brazil. Type collected by Martius.

Kichler records this species from along the Rio Negro between Barcellos and 
Santa Isabel, and from near Mandos, as well as from the type locality. He 
describes also a variety grandifolia, with leaves 15 to 20 cm. long, 6 to 10 cm. 
wide, from woods near Ega, where it was collected by Martius. My description 
is drawn from the excellent specimen in the Gray Herbarium collected by Traill.

Branchlets puberulous and hispid, glabrate; leaves opposite; petioles densely 
puberulous and somewhat hispid, 4 mm. long; blades elliptic or elliptic-oval, 5 
to 8 cm. long, 2 to 2.8 cm. wide, obtusely short-pointed, at base cuneate or 
rounded-cuneate, pergamentaceous, crenate-serrulate, puberulous on costa above, 
beneath strigose on costa and often on veins, sometimes also on surface, some- 
times barbate in the axils of the veins; racemes about 4 cm. long or less, densely 
sordid-puberulous; pedicels 8 mm. long, or obsolescent ; sepals oval or oval- 
ovate, 2.4 to 2.7 mm. long, acutish to obtusish, ciliolate, on back sparsely or 
usually densely puberulous, strongly striate; petals eHiptic or lance-elliptic, 
4.5 to 6 mm. long, obtuse, shortly reflexed, glabrous except for the ciliolate- 
tufted apex ; stamens 3.8 to 4 mm. long, the filaments 0.6 to 0.8 mm. long, about 
twice as long as the sometimes pubescent apically free glands, the anthers 1.8 
to 16 mm. long, unappendaged or rarely bearing at apex one or two filiform 
setae, the connective scales 3 to 3.2 mm. long, oblong-ovate, obtuse, finely erose; 
ovary densely hispid, the placentae 1 or 2-ovulate.

Hichler considered Bentham’s two species to represent two varieties of 
Alsodeia guianensis (R. passoura), distinguished in common from the typical 
form by their small leaves, and from one another chiefly by the difference in 
length of the pedicels. Fortunately both species are represented in the U. 8.

cisely in all features except the inflorescence. The specimen of A. brevipes
