AMERICAN PASSIFLORACEAE 341
sometimes only two, petiolar glands and narrower stipules, and the
leaves usually are smaller, with nerves farther apart and more
strongly arcuate. Constant coronal differences between the two are
not apparent in the herbarium material at hand, though Masters
has noted that an "intermediary corona" is present between the
operculum and the true (faucial) corona in P. quadrangularis and
absent in P. alata.
Passiflora alata evidently is quite variable; some of the names
here listed in synonymy may refer to plants that are sufficiently
distinct from typical P. alata to constitute at least valid varieties.
In Masters' variety brasiliana the stipules are very narrow, scarcely
more than 2 mm. wide; in his variety mauritiana, known only from
the islands of Mauritius and Bourbon, the leaves are minutely
denticulate.
Passiflora latifolia, having four glands and broad leaves,
is perhaps a hybrid of P. quadrangularis and P. alata.
The following are probably horticultural hybrids of this species:
P. Decaisneana (P. alataXP. quadrangularis), P. Lawsoniana Hort.,
not Mast. (P. alataXP. racemosa).
