1883.<br />
Scandent shrub (?); tendrils few or none; branches terete, finely<br />
puberulent, glaucescent; petioles 1 to 3 cm. long, glandless, finely<br />
puberulent; leaves narrowly oblong, 10 to 20 cm. long, 4 to 7 cm.<br />
wide, short-acuminate, rounded or slightly narrowed at base, entire,<br />
penninerved (principal lateral nerves 10 to 15 to a side, rather prominent,<br />
the intermediate secondary nerves fainter, the midnerve<br />
biglandular near base), reticulate-veined, subcoriaceous, light green,<br />
sublustrous, glabrous; peduncles solitary, 3 to 4 cm. long, slender,<br />
articulate above middle, puberulent; bracts setaceous, 1 to 1.5 mm.<br />
long, deciduous, borne at point of articulation; calyx tube shortcampanulate,<br />
2 to 4 mm. long, 5 to 7 mm. wide at throat, introrse;<br />
sepals oblong, 2 to 2.5 cm. long, 0.8 to 1 cm. wide, obtuse; petals<br />
similar to the sepals; outer corona filaments 2 to 2.5 cm. long, falcatedolabriform<br />
(dilated portion shallowly lobed or deeply cleft at inner<br />
margin), smooth at margin, the inner filaments in 4 or 5 series,<br />
to about 4 mm. (lower),<br />
decreasing in length from 7 mm. (upper)<br />
capillary, capitellate, erect; operculum arising about 3 mm. above<br />
base of tube, about 1 mm. long, dependent, crenulate; ovary oblong,<br />
rufo-tomentellous; styles hirsutulous.<br />

In describing this interesting species Masters comments on the<br />
deep tubular "basal corona" and on the absence of a "middle corona."<br />
As mentioned elsewhere, the use of the terms "middle" and "basal"<br />
for the two interior corona-like processes of Passiflora was not wholly<br />
satisfactory. In the case of P. deficiens the interior membrane is<br />
borne very close to the floor of the calyx tube, much below its middle.<br />
However, from its structure it is far more like the operculum of other<br />
species of Astrophea than like the true limen (basal corona) in Plectostemma,<br />
Dysosmia, and Granadilla.<br />
