502 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
The reasons for the reference of Conohoria castanefolia to the synonymy of 
this species are given under R. guianensis (no. 6).

TYPE Locality; Near Lake Teffé and elsewhere on the shore of the Solimoes, 
Brazil. Type collected by Martius, 
SPECIMEN EXAMINED: 
Brazi_: Near Panuré, on the Rio Uaupés, 1852-53, Spruce 2519 (G). 
The above description is drawn up partly from the original and from 
Kichler, and partly from the single specimen examined, which is not in good 
condition for description. This collection (Spruce 2519) is referred to by 
Kichler as a variety with firmer, more veiny leaves and shorter racemes. 
11. Rinorea sprucei (Hichl.) Kuntze, Rey. Gen. Pl. 1:42. 1891. 
Alsodeta sprucei Kichl, in Mart. Fl. Bras, 18': 385. 1871. 
Branchlets sordid-puberulous; leaves opposite ; petioles 4 to 7 mm. long, 
incurved-puberulous ; blades elliptic or elliptic-oval, 12 to 23 cm. long, 3 to 8 
cm. wide, long-attenuate and cuspidulate, at base acutely cuneate, papyra- 
ceous, entire or slightly repand, above deep green, incurved-puberulous along 
costa and sometimes along veins, beneath paler or glaucescent, uniformly 
strigillose, sometimes pilose-tufted in the axils; panicles subspiciform, about 
13 cm. long or less, about 12 mm. thick, rufidulous-puberulous, the cymules 3 
to 6-flowered ; sepals oval or ovate, obtuse, ciliolate and puberulous, 1.5 mm. 
long; petals ovate, 3.2 to 3.5 mm. long, narrowed to a rounded somewhat 
reflexed apex, puberulous along middle of back; stamens 2.8 mm. long, the 
filaments 0.38 mm. long, inserted inside a pubescent disk, the anthers 0.8 mm. 
long, not appendaged, the connective scales lance-ovate, 2.5 mm, long, narrowed 
to apex, entire, glabrous; ovary glabrous, the placentae 2-ovulate; “seeds 2 to 
each placentae, 3.5 mm. long.” 
TYPE LOCALITY: Along the Rio Negro and Rio Uaupés, Brazil. Types collected 
by Spruce (nos. 1834, 1947, 2633). 
SPECIMENS EXAMINED: 
BritisH GUIANA: Along the Rio Negro, 1840, Schomburgk 947 (N). 
BraziL; Along the Rio Negro, between Barra and Barcellos, 1851, Spruce 
“1834 & 1947” (type collection ?; G). 
This species is distinguished from its only close relative, R. racemosa, by its 
long-attenuate léaves, which are distinctly paler beneath, and its longer petals, 
as well as by the different number of ovules. The difference in venation indi- 
cated by Eichler does not seem to be of much consequence. LTichler describes 
the anthers as similar to those of R. racemosa, except that their appendages
