BLAKE—-NEW PLANTS FROM VENEZUELA, 541 
lanate-tomentose with ochroleucous or griseous hairs, feather-veined, the lateral 
veins 7 to 9 pairs, impressed or prominulous above, prominulous beneath ; scapes 
solitary, monocephalous, densely ochroleucous-lanate-tomentose, glabrescent, 
bearing scattered minute bracts similar to the outer phyllaries; head 2.5 cm. 
wide; disk turbinate, 1 to 1.2 em, high, 1.2 to 1.6 cm. thick; involucre about 6- 
seriate, graduate, 1.1 to 1.3 cm. high, appressed, glabrous, the 3 outer series of 
pliylaries lance-linear or linear, acuminate, 4.5 mm. long or less, olive-green, 
2-ribbed and with 2 central vittae, firm and somewhat rigid, the 2 innermost 
series broader and thinner, linear, acute or acuminate, with narrow subscarious 
margin, few-nerved above, the fourth series intermediate in length and char- 
acters; rays 2-seriate, bilabiate, pistillate, those of the outer series about 22, 
erect, apparently whitish, glabrous, the tube 2.5 mm. long, the outer lip nar- 
rowly elliptic, tridenticulate, 9 mm. long, 2 mm, wide, 4-nerved, the inner lip of 
2 small erect teeth about 0.5 mm. long; those of the inner series few, similar 
but with shorter outer lip, this surpassing or slightly shorter than the style, 3.5 
to 6 mm. long, tridentate with elongate central tooth or bidenticulate, in the 
latter case with a short supplementary third tooth to the inner lip; disk flowers 
hermaphrodite, their corollas glabrous, 7.5 mm. long, bilabiate, their lips erect, 
the outer tridenticulate, 3.5 mm. long, the inner equal, 2-parted to base into 
erect linear-lanceolate lobes; receptacle naked, glabrous, flattish; ray achenes 
(submature) fusiform, subrostrate, glabrous, not papillose, 5-nerved, 4.2 mm. 
long; disk achenes (immature) apparently similar; pappus of numerous, about 
2-seriate, equal, slender, hispidulous, whitish or purplish-tinged setae 5 to 6.5 
mm. long, irregularly and slightly connate at extreme base; anther tails sub- 
ulate-acuminate, subentire, 1.2 mm. long; style branches (hermaphrodite 
flowers) very short, rounded, erect, minutely hispidulous, 0.4 mm. long. 
Type in the U. S. National Herbarium, po. 1,069,625, collected on the Péiramo 
del Molino, Mérida, Venezuela, altitude 2.200 meters, February 19, 1922, by 
Alfredo Jahn (no. 954). 
Although this plant, which is very similar to species of Trichocline in ap- 
pearance, is certainly referable to Chaptalia by virtue of its subrostrate achenes 
and the presence of reduced inner pistillate flowers, it departs from the 
definitions of that genus given by Bentham and Hooker and by O. Hoffmann in 
its bilabiate pistillate corollas. Several species having pistillate corollas with a 
short inner lip have been described, however, and among them the Peruvian 
Chaptalia rotundifolia D. Don seems to be the closest ally of C. meridensis. 
C. cordata Hieron., of Colombia and Peru, is also related to C. meridensis, but 
from description appears to differ decidedly in the narrower, cordate-ovate or 
cordate-elliptic leaves, only 2.5 to 2.8 cm. wide, the broader bracts of the scape 
(up to 2 mm. wide nt base), the broader phylaries, and the 3-nerved, bidentate 
ligules.
