AMERICAN PASSIFLORACEAE 205
Passiflora Andersonii is glabrous throughout, and the leaves are
broader than long; P. rotundifolia is densely pubescent, and the
leaves are nearly orbicular. The Duss specimens are confusing, as
he distributed specimens of both species with a single label bearing
two or more collection numbers.
100. Passiflora micropetala Mast, in Mart. Fl. Bras. 13, pt. 1:
585. 1872.
Stem compressed, flexuous, glabrous; petioles 4 to 6 mm. long,
glandless; leaves semi-orbicular, about 6.5 cm. long and 9 cm. wide,
truncate at apex, obsoletely 3-lobed, mucronate, cordate at base,
ocellate with 2 glands near base, membranous, green above, winered
beneath, glabrous(?); peduncles solitary or in pairs; bracts
unknown; flowers white; sepals triangular, broad, erect; petals ovate,
small, white; corona filaments in 2 series, the outer clavate, obtuse,
white, green at base, the inner ones few, filiform; operculum plicate,
fimbriate at the apex; ovary globose; fruit globose, about 1.5 cm.
in
diameter.
TYPE LOCALITY: Rio Japura, State of Amazonas, Brazil (type
collected by Martius).
This is one of the few species maintained as valid by Masters in
the Flora Brasiliensis that I know only from description. The semiorbicular,
obscurely 3-lobed leaves suggest several species in Plectostemma,
but all these differ in one or more details from other characters
given by Masters. The position it should occupy in the present
treatment is doubtful.
101. Passiflora rotundifolia L. Sp.
PI. 957. 1753.
Decaloba rotundifolia M. Roemer, Fam. Nat. Syn. 2: 159. 1846.
Plant densely ferruginous-tomentose nearly throughout, or the
older portions becoming merely pilosulous; stem angulate; stipules
setaceous, 2 to 3 mm. long, deciduous; petioles 1 to 3 cm. long, glandless;
leaves suborbicular, 3 to 7 cm. long and wide, obscurely 3-lobed
at apex (lobes rounded, mucronulate, the middle one subequaling
or shorter than the lateral), rounded or subtruncate at base, 3-nerved,
ocellate, membranous or subcoriaceous, minutely pilosulous and
dull above, densely pilosulous beneath, especially on nerves, or
ferruginous-tomentose; peduncles usually in pairs, 1 to 2.5 cm.
long, articulate near apex; bracts setaceous, 2 to 3 mm. long, at
length deciduous; flowers 2.5 to 3 cm. wide, white; sepals linearlanceolate,
4 to 5 mm. wide at base, obtuse, dorsally green at center,
