530 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX slender sepals and petals. Unfortunately the structure of the operculum is not evident in the few flowers preserved with the specimens, or in the painting. 317. Passiflora ovata Martin ex DC. Prodr. 3: 322. 1828. Astrophea ovata M. Roemer, Fam. Nat. Syn. 2: 151. 1846. Tree or shrub (?) with a few weak tendrils, glabrous throughout except the ovary; stipules linear, about 2 mm. long; petioles up to 3 cm. long, purplish, biglandular at the junction with the blade; leaves oblong, 6.5 to 11 cm. long, 3.5 to 5.5 cm. wide, rounded or almost truncate at the apex, rounded or subacute at base, penninerved (about 6 nerves to a side), subcoriaceous, bright green on both surfaces, sublustrous above; peduncles about 2 cm. long, bifurcate, the pedicels 5 to 8 mm. long; bracts linear, about 2 mm. long; calyx tube very short, campanulate-funnel-shaped, 2 to 3 mm. long, 8 to 10 mm. wide at the throat; sepals lanceolate, about 2 cm. long, 1 cm. wide at base, obtuse; petals slightly shorter than the sepals; corona 2-ranked, the outer series subdolabriform, about 1 cm. long, enlarged at the middle, the inner about 2 mm. long; operculum(?); ovary white-tomentose. TYPE LOCALITY: French Guiana. Known only from the type locality. FRENCH GUIANA: Cayenne: Martin (BM, type). This species is known only from the single specimen preserved in the British Museum. In the Flora Brasiliensis Masters referred to it several collections from western South America, but subsequently he adopted (Journ. Linn. Soc. 20: 33. 1883) the views of Triana and Planchon that all of these represented other species, and he presented a redescription of P. ovata based solely upon the Martin specimen. He also pointed out, quite correctly, that Triana and Planchon had wrongly identified a plant of P. costata as this, and that their detailed description of the flower structure of P. ovata was for that reason erroneous. The type specimen is in good condition, but its flowers have never been dissected sufficiently to permit a view of the operculum. The shape and texture of the leaves suggest P. deficiens, of the section Pseudoastrophea, and perhaps this species should be placed there. The single peduncle is definitely forked, however, and until additional material is collected, it seems best to refer the species to Euastrophea.
AMERICAN PASSIFLORACEAE 531 318. Passiflora grandis <strong>Killip</strong>, sp. nov. Frutex; petioli hirsutuli vel fere tomentulosi ; folia late ovata vel ovato-oblonga, ad apicem rotundata et emarginata, subcoriacea, supra glabra, subtus in nervis venisque dense hirsutula et ad basin 5-6-glandulosa, glandulis crateriformibus, flavidulis; pedunculi dichotomi, hirsutuli; calycis tubus campanulatus, sepalis petalisque oblongis; coronae filamenta 3-seriata, extima falcata, anguste dilatata, interioria filiformia; operculum subtiliter erosum; ovarium tomentosum. Shrub, 1.5 meters high, the branchlets terete, the cortex dark brown, minutely tomentulous with black hairs, at length glabrescent; stipules soon deciduous; petioles stout, 2.5 to 3 cm. long, densely and minutely hirsutulous or nearly tomentulous, glandless; leaves broadly ovate or ovate-oblong, 20 to 28 cm. long, 12 to 17 cm. wide, rounded and emarginate at apex, rounded or subtruncate at base, entire, penninerved (lateral nerves about 14 to a side), subcoriaceous, glabrous above, pale beneath, densely hirsutulous on the strongly elevated nerves and veins beneath, the under surface bearing near its base and close to the costa 5 or 6 crateriform, yellowish glands about 1 mm. in diameter; peduncles 5 to 7 cm. long, hirsutulous with blackish hairs, twice dichotomous, the common peduncle and the branched portion subequal; bracts subulate, soon deciduous; calyx tube campanulate, about 7 mm. long, 6 mm. wide at throat; sepals oblong, 1.5 to 2 cm. long, about 6 mm. wide, obtuse, white, redspotted; petals subequal and similar to the sepals; corona filaments in 3 series, the outer falcate, narrowed, dilated above middle, 7 to 9 mm. long, laterally compressed, those of the inner 2 filiform, 1 mm. long; operculum membranous, erect, about 1 mm. high, shallowly erose; ovary short-ovoid, densely whitish-tomentose. collected in Type in the herbarium of the Royal Botanic Gardens, Kew, the Province of Ocana, Department of Norte de Santander, Colombia, altitude 1,135 meters, by L. Schlim (No. 585). Duplicates at Bo, Brux, Gen, and P. This collection was cited by Masters in the Flora Brasiliensis as P.. emarginata. Triana and Planchon likewise referred it to that species and their redescription of P. emarginata was doubtless in part derived from this collection. Though I am reluctant to create another close segregate in this highly complex group, the specimens of Schlim 585 do not well fit into P. emarginata or its segregates, though in gross characters they bear a general resemblance. Masters has written on the type sheet "See numerous glands at base of leaf,
