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 />
