PERU: Loreto: La Victoria, Amazon River, L. Williams 3086 (F,
N, type).
This is most closely related to P. Oerstedii, and though the differences
seem slight when stated in a key, this single specimen of P.
loretensis appears much unlike any of the specimens of P. Oerstedii
at hand. The leaves are much thicker and are green on both surfaces.
The bracts are larger.
258. Passiflora Rojasii Hassl. ex Harms, Notizbl. Bot. Gart.
Berlin 10: 812. 1929.
Stem slender, sparsely pilosulous or puberulous; stipules semiovate-lanceolate,
1 to 2 cm. long, 0.3 to 0.4 cm. wide, cuspidateacuminate;
petioles 1.5 to 3.5 cm. long, bearing 4 to 8 filiform
glands about 1 mm. long; leaves oblong-lanceolate or ovate-lanceolate,
7 to 10 cm. long, 3.5 to 5 cm. wide, acute at apex, cordulate
or subtruncate at base, 5-nerved, glabrous above, puberulous or
pilosulous and glaucescent beneath; peduncles solitary, about 3.5
cm. long; bracts deltoid-ovate, 1 to 1.2 cm. long, 7 to 8 mm. wide,
cordate at base, sessile, borne about 6 mm. below base of flower;
flowers 7 to 8 cm. wide (expanded) ; calyx tube campanulate, 7 to 8
mm. long, about 12 mm. wide; sepals oblong-lanceolate, 3.5 to 4
cm. long, 7 to 8 mm. wide, dorsally awned just below apex, the awn
5 to 6 mm. long; petals linear, slightly shorter than sepals; corona
filaments in 5 series, those of the 2 outer series filiform, 2.5 to 3 cm.
long, those of the 3 inner ones about 5 mm. long, minutely capitellate;
operculum 6 to 7 mm. high, filamentose in upper third; nectar
ring annular; ovary ovoid, glabrous, pruinose.
TYPE LOCALITY: Sierra de Amambay, Paraguay.
DISTRIBUTION: Bolivia, central Brazil, and Paraguay.
BOLIVIA: Antahuacana, Espiritu Santo, 750 meters, Buchtien
4652 (N).
BRAZIL: Matto Grosso: Santa Anna, Malme in 1902 (S).
PARAGUAY: Sierra de Amambay, Rojas (Hassler 10305; B,
type, BM).
The differences between this species and P. Oerstedii are perhaps
too slight, but it is improbable that the species of northwestern
South America extends into Paraguay. The Bolivian specimen
seems intermediate between typical P. Rojasii and P. praeacuta,
having an indument somewhat similar to that of the latter.
