BLAKE—-NEW PLANTS FROM VENEZUELA, 529 
exaristate, 1.2 mm. long, the 2 tubules 1.5 mm. long; ovary 4-celled; style 4.5 
mm. long. . 
Type in the U. S. National Herbarium, no, 703598, collected on the Piramo de 
Piedras Blancas, Mérida, Venezuela, altitude 3,800 meters, March 27, 1915, 
by Alfredo Jahn (no, 427). 
Closely related to Vaccinium floribundum H. B. K., in which the filaments 
are densely pilose-ciliate. Evidently allied also to V. thymifolium and V. 
moritzianum Klotzsch, both of which are included by Klotzsch in the section 
Vitis-Idaea, to which pilose filaments are ascribed in his synopsis. 
Thibaudia jahnii Blake, sp. nov. 
Shrub; stem angulate, essentially glabrous; petioles stout, glabrous, 8 to 8 
mm. long; leaf blades elliptic or obovate-elliptic, 5 to 8 em. long, 2 to 3.8 em. 
wide, short-pointed with obtuse apex, cuneate at base, entire, thick-coriaceous, 
above glabrous, somewhat shining and pustulate, beneath dull brownish green, 
sparsely hispidulous with brownish hairs, narrowly revolute-margined, feather- 
veined, the chief veins about 3 pairs, impressed or obscure above, bluntly 
prominulous beneath; racemes axillary, solitary, subsessile, glabrous, about 10 
to 16-flowered, the axis 2 to 3 cm. long; bracts ovate, deciduous, about 1.8 
mm. long; pedicels 10 to 12 mm. long, glabrous, thickened at apex and articu- 
late with calyx, bearing near base 2 subopposite ovate acute bractlets about 
1.8 mm. long; calyx glabrous, campanulate, 4.5 mm. long, the limb with 5 very 
short, depressed-deltoid, acute or obtuse teeth; corolla subcylindric, fleshy, gla- 
brous, 12 mm. long, the teeth 5, ovate, erect, obtusish; stamens 10, equal, 10 
mm. long, the filaments linear-lanceolate, glabrous, 5.5 mm. long, the anther 
sacs finely granular, apiculate at base, 4 mm. long, the 2 tubules 5 mm. long; 
ovary 5-celled; style 11 mm. long. 
Type in the U. S. National Herbarium, no. 703595, collected on the Paramo de 
Pifiango, Mérida, Venezuela, altitude 2,600 meters, March 17, 1915, by Alfredo 
Jahn (no. 424). 
A member of the section Hurygania, nearest Thibaudia formosa (Ilotzsch ) 
Hérold, from Mount Roraima, which has much shorter racemes (axis 6 to 8 
mm. long), longer pedicels (12 to 18 mm.), and shorter corolla (8 to 10 mm.). 
The vernacular name of T. jahnii is given as “ eoralito,” referring doubtless tc 
the color of the flowers. 
APOCYNACEAE. 
Forsteronia elachista Blake, sp. nov. PuaTeE 41 
High-climbing shrub; branches gray, glabrous, the younger fuscous, very 
obscurely hirtellous, glabrescent; leaves opposite; petioles 5 to 7 mm. long, 
obscurely hirtellous; blades cval or oblong-oval, 6.5 to 12 cm. long, 3 to 5.7 
cm. wide, obtusely short-pointed, at base broadly rounded, subcoriaceous, above 
dull green, glabrous, beneath brownish green, barbate in the axils, the veins 
about 8 pairs, like the costa impressed above, prominulous beneath, the second- 
aries obscure; panicles terminal, finely hirtellous, on peduncles 4 to 12.5 cm, 
long, pyramidal, 12.5 to 23 cm. long, 18 to 30 cm. wide, the branches spreading 
at right angles, with innumerable flowers, these cymose-paniculate toward the 
tips of the dichotomous ultimate branchlets; bracts triangular, griseous- 
hirtellous, 1 mm. long or less; pedicels abont 1 mm. long; calyx 1.1 mm, long, 
densely griseous-hirtellous, the sepals oval, obtuse, about 3-glandular at base; 
corolla brownish black in drying, 1.5 mm. long, the tube 0.6 mm. long, glabrous, 
the lobes oblong-ovate, obtuse, 0.9 mm. long, griseous-hirtellous outside, 
hispidulous within; stamens exserted, 0.8 mm. long, the filaments 0.15 mm. 
long, the basal appendages of the anthers obovoid, obtuse, the apex acutish and
