526 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM, 
ADDITIONAL SPECIMENS EXAMINED! 
VENEZUELA: Cultivated, Borburata, near Puerto Cabello, July 15, 1913, 
Pittier 6464. Cultivated, Valencia, January, 1919, Pittier 8411. 
A member of the section Hucouwmarouna, related to Coumarouna alata (Vog.) 
Taub., which may be distinguished by its nearly glabrous calyx wings only 6 
mm. long. Also close to C. odorata Aubl., to which two of the specimens ahove 
cited have been referred. In that species, however, according to Bentham’s 
description,’ the leaflets (usually 6 to 8) are impunctate, and the petiole is 
terminated by a long acumination. In Ducke 12185, in the National Herbarium, 
which agrees in these characters with Bentham’s description, the pubescence of 
the panicle is of a much deeper brown than in the specimens of C. punctata. 
GERANIACEAE. 
Geranium sebosum Blake, sp. nov. 
Perennial, about 25 em. high or more, multicipital, the caudex 7 mm. thick 
below, at apex about 1.5 em. thick (including the stipules and leaf bases) ; basal 
leaves numerous; stipules ovate-oblong, acute, brown, scarious, pilose, about 8 
mi. long; petioles slender, 8 to 12 cm. long, densely spreading-pilose with lax 
1-celled hairs 1.5 to 3 mm. long and between them densely stipitate-glandular 
with several-celled hairs about 0.56 mm, long; blades reniform-orbicular, 3 to 
4 cm. wide, pergamentaceous, densely subsericeous-pubescent and stipitate- 
glandular like the petioles and also sessile-glandular, 5-lobed about halfway to 
base, the lobes broadly cuneate or cuneate-quadrate, the central one (sometimes 
also the two lateral) 3-toothed with obtuse teeth, or sometimes shortly 3-lobed 
with entire or 1 to 3-dentate Icbes, the two basal and often the two lateral 
2-lobed about half their length, the lobes with 2 or 8 blunt teeth; stem stoutish, 
erect, similarly pubescent, naked below the inflorescence; stem leaves opposite, 
similar to the basal but smaller, 2.2 cm. wide, their petioles about 7 mm. 
long, the stipules about 5 mm.; inflorescence short, trichotomous with di- or 
trichotomous branches, pubescent like the stem but more conspicuously 
stipitate-glandular ; central peduncle 2 em. long, the others usually suppressed, 
the pedicels paired, 1.5 to 2 em. long; calyx densely spreading-pubescent with 
several-celled, mostly gland-tipped hairs about 0.8 mm. long, the sepals oval, 6 
mm. long, 3 mm. wide, 3-nerved, obtusely apiculate at the broadly rounded apex 
(mucro 0.3 mm. long) ; petals apparently magenta, 9 mm. long (claw 2.5 mm.), 
6 mm. wide, the limb cuneate-suborbicular, subtruncate, minutely stipitate- 
glandular on margin above, otherwise glabrous; filaments lance-subulate, not 
denticulate, pilose-cilate and stipitate-glandular on margin nearly to apex; fruit 
(including styles) 15 mm, long, the beak 1 em. long, densely pubescent like the 
sepals, the carpel bodies pilose with chiefly eglandular hairs; seeds (immature) 
minutely areolate, 2 mm. long. 
Type in the U. 8S. National Herbarium, no. 602198, collected on the PAéramo 
de Timotes, Mérida, Venezuela, altitude 4,000 meters, March, 1910, by Alfredo 
Jahn (no. 5). 
A member of the section Gracilia R. Knuth, and nearest Geranium holoser- 
iceum Willd. In that species, according to Knuth’s monograph, the stem is 
glabrescent below, and merely puberulous above; the leaves are more deeply 
lobed ; the stipules are much longer, and the lowest are glabrous: the peduncles 
are much longer and only sparsely pubescent; the sepals are larger, and the 
petals much larger. The specific name refers to the greasy feeling of the 
entire plant.
