BOTANICAL EXPLORATION IN VENEZUELA - I 123<br />

6-7 cm. longis, 4- vel 5-costatis,. tortis, dense breviterque pubescentibus<br />

dein praeter apicera glabrescentibus.<br />

Caulescent herb; stems slender, to about 10 cm. long, branched,<br />

very leafy; leaves firm and tough, elongate lanceolate, somewhat<br />

twisted or falcate-conduplicate in age, 2.5-4 cm. long, 3-7 mm. wide<br />

at the mid-point, acute at the apex, many-striate, not fenestrate,<br />

spreading, sheathing the stem at the base, densely white-villous with<br />

tangled white hair when young on the upper surface, glabrescent in<br />

age, obscurely subappressed-pilose on the lower surface (densely so<br />

when very young, sparsely so in age); sheaths cylindric, rather loose,<br />

about equaling the uppermost leaves, 1.5-2 cm. long, rather densely<br />

short-pubescent with appressed antrorse hairs, less so in age, obliquely<br />

split at the apex, the blade lanceolate, erect or the tip<br />

spreading or recurved, 5-7 mm. long, more or less long-ciliate on the<br />

margins; peduncles slender, 5-15 per plant, 6-7 cm. long, 4- or 5-<br />

c estate, twisted, densely short-pubescent with subappressed antrorse<br />

hairs, glabrescent in age except for the very tip; heads hemispheric,<br />

6-7 mm. in diameter; involucral bractlets broadly triangular- ovate,<br />

dark-brown, about 2 mm. long, about 1.5 mm. wide at the base, shortacuminate<br />

at the apex, ciliolate-margined, otherwise glabrous; receptacle<br />

densely long-villous; receptacular bractlets absent; staminate<br />

florets: sepals 3, separate to the base, firm, erect, brownish,<br />

darkest toward the apex, oblanceolate, about 1.4 mm. long and 0.5<br />

mm. wide, acute, the margins more or less involute, densely bearded<br />

at the apex on the back, otherwise glabrous, not glanduliferous;<br />

petals 3i united into a hyaline infundibular tube about 1.7 mm. long,<br />

glabrous, narrow-cylindric for about the lower half of its length,<br />

abruptly ampliate to 0.8 mm. at the apex, its rim 3-apiculate; stamens<br />

3, opposite the corolla-apiculations, inserted on the corolla-tube<br />

about 0.4 mm. below its apex; filaments slender, about 0.4 mm. long,<br />

glabrous, equaling the corolla-apiculations; anthers white, versatile,<br />

oblong, about 0.3 mm. long, composed of 2 separate thecae, each<br />

dehiscing by means of a longitudinal slit; style about 1.3 mm. long,<br />

the upper 0.4 mm. trifid; ovary absent; pistillate florets few: sepals<br />

3, lingulate, firm, erect, about 1.2 mm. long, rather uniformly about<br />

0.6 mm. wide throughout, obtuse at the apex, light-brown toward the<br />

apex and in a median band to the base, hyaline-margined toward the<br />

base, more or less densely long-villous on the back and shortbearded<br />

at the apex, or only densely bearded, not glanduliferous;<br />

petals 3, separate almost to the base, subhyaline, erect, ellipticoblong,<br />

about 13 mm. long and 0.4 mm. wide, subacute at apex,<br />

glabrous on the back, very densely long-villous on the inner surface<br />

with white hairs surpassing the petals in length, not bearded, not<br />

glanduliferous; style about 0.6 mm. long, glabrous, terminated by 3<br />

clavate style -appendages and 3 bifid stigmas, all 0.4-0.5 mm. long;<br />

ovary small, subglobose, about 0.4 mm. long and wide, glabrous,<br />

3-celled.<br />
