346. Passiflora cauliflora Harms, Verhandl. Bot. Verein. Brandenburg
48: 185. 1906.
Scandent shrub, glabrescent throughout except the ovary;
petioles about 3 cm. long, biglandular near apex; leaves oblong,
15 to 18 cm. long, 6 to 10 cm. wide, obtusely acuminate or acute,
rounded at base, penninerved (principal lateral nerves 9 to 11 to a
side, prominent beneath), thick-coriaceous, with a dark, thickened
band at the margin; flowers "brown-yellow," borne in axillary
fascicles, the rachis nodulose, up to 2 cm. long, the pedicels about
3 mm. long; calyx tube cylindric, 1.5 to 2 cm. long, 3 to 4 mm. in
diameter; sepals oblong, about 2 cm. long and 6 mm. wide, obtuse;
petals similar to the sepals; corona filaments in 3 series, the outermost
subdolabriform, 1.2 to 1.5 cm. long, those of the 2 inner series narrowly
linear, 2 to 3 mm. long; operculum borne at middle of tube,
erect, about 1 cm. high, cleft in the upper third into 5 linear segments;
ovary narrowly obovoid, finely and softly ferruginoustomentellous.
TYPE LOCALITY: Cerro de Escalera, Department of Loreto, Peru.
DISTRIBUTION: Amazonian Peru.
PERU: San Martin: Zepelacio, King 3469 (N). Loreto: Cerro
de Escalera, near Tarapoto, Ule 6679 (B, type, Go). Mouth of
Rio Santiago, Tessmann 4588 (B).
This is very similar to P. skiantha, described from the same
general locality. Both have an unusual operculum, this being longer
than in most species of Botryastrophea, and cleft into five linear
segments. In P. cauliflora the operculum
is tubular in the lower
two-thirds, cleft only at the apex, whereas in P. skiantha the operculum
is cleft nearly to its base. Other differences between the two are
the shorter calyx tube and pubescent ovary of P. cauliflora.

but slightly narrower than the sepals; corona filaments in 4 series,
