518 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX by Masters in Granadilla, its true relationship seems to be with P. villosa and P. Vellozii. Passiflora Bolstadii is scarcely distinct from P. campanulata. Duse'n points out that in P. Bolstadii the leaves are glabrous except for hairs at the margin and on the nerves, their lobes are entire, the stipules are shorter, and the bracts are persistent, whereas in P. campanulata, with which he compares it, the leaves are villous, the lobes serrulate, and the bracts deciduous. Subgenus XXI. POLYANTHEA 307. Passiflora cirrhiflora Juss. Ann. Mus. Hist. Nat. 6: 115. pi. 41, f. 2. 1805. Passiflora septenata DC. Prodr. 3: 323. 1828. Decaloba cirrhiflora M. Roemer, Fam. Nat. Syn. 2: 164. 1846. Passiflora Jenmani Mast, in Hook. Icon. PI. 23: pi 2270. 1893. Stem terete, glabrous or puberulent; stipules setaceous; petioles up to 10 cm. long, biglandular about 1 cm. above base, the glands sessile, often scarcely more than a scar; leaves pedately 5-7-foliolate, the leaflets oblong, 5 to 8 cm. long, 3 to 4 cm. wide, acute or acuminate, and long-aristate at apex, narrowed at base to the petiolule, aristate-bidentate near base, membranous, glabrous throughout or finely puberulent beneath; peduncles solitary, stout, 1 to 4 cm. long, 2-flowered at apex, terminating in a stout tendril, the pedicels 2 to 5 cm. long; bractlets borne at base of flower, linear-subulate, about 1 cm. long, biglandular at base; flowers reddish purple, 6 to 8 cm. wide; calyx tube broadly campanulate, 5 to 10 mm. long; sepals oblong, about 3 cm. long, 7 to 8 mm. wide, obtuse, fleshy, puberulent without; petals linear-oblong, about 2.5 cm. long, 6 to 7 mm. wide, thin, manyveined; corona filaments in 3 series, the outermost liguliform, about 3 cm. long, crispate in upper half, verrucose or fimbrillate along the margin, white at base, yellow at middle, tipped with dark red, those of the 2 inner series narrowly linear, 1 cm. long, capitate; operculum membranous, closely plicate, fimbrillate; limen tubular, 6 to 8 mm. high, closely surrounding base of gynophore, 5-lobed; ovary ovoid, trigonous, truncate, densely tomentellous; styles thick, 2 mm. long, projecting at the top of the angles of the ovary; stigmas orbicular, 5 mm. in diameter; fruit globose, the pericarp coriaceous; seeds broadly obovate, about 7 mm. long and 4.5 mm. wide, transversely 5-6-sulcate. TYPE LOCALITY: French Guiana.
AMERICAN PASSIFLORACEAE 519 ILLUSTRATIONS: Ann. Mus. Hist. Nat. 6: pi. 41, f. 2; Hook. Icon. PI. 23: pi. 2270. DISTRIBUTION: Guianas. FRENCH GUIANA: Collector (?) (Gen, P, type of P. septenata); Richard (Gen, P, type). SURINAM: Upper Saramacca River, near Janbasigado, Pulle 200 (Ut). BRITISH GUIANA: Mazaruni River, Jen-man 5797 (EG, type collection of P. Jenmani), 6512 (Y); Waby in 1905 (B). Potaro, Jenman 7511 (BG). Yarikita, Hitchcock 17602 (G, N, Y). Waini River, De la Cruz 3621 (Y). The systematic position of this unique species is uncertain. Because of the plicate operculum it has usually been placed in Plectostemma. The truncate ovary, with the styles projecting from the angles at its top, and the verrucose outer corona filaments indicate a closer relationship with Astrophea. The stigmas are much larger than in any other species of Passiflora. This should be considered the type species of De Candolle's section Polyanthea; it is the first one cited and, moreover, the description of the section applies best to it. Two other American species, P. holosericea and P. sexflora, placed in the section by De Candolle, and P. multiflora, added to it by Masters, have little in common with P. cirrhiflora, and should be eliminated from Polyanthea. Subgenus XXII. ASTROPHEA Section 1. Dolichostemma 308. Passiflora Haughtii <strong>Killip</strong>, sp. nov. Frutex scandens, ecirrhatus, caule rufo-hirsutulo; folia oblanceolata, acuminata, ad basin angustata, penninervia, integerrima, membranacea, supra glabra, subtus dense hirsutula; pedunculi semel dichotomi, bracteis subulatis; calycis tubus campanulatus, sepalis petalisque lineari-oblongis; corona 5-seriata, filamentis extimis dolabriformibus, alteris brevioribus, ligulatis vel filiformibus; operculum longe tubulosum, exsertum, erosum; ovarium ovoideum, truncatum, dense hirsute-tomentosum. A large liana but apparently without tendrils, the stem densely rufo-hirsutulous; stipules linear-lanceolate, about 2.5 mm. long, soon deciduous; petioles 1 to 1.5 cm. long, stout, eglandular; leaves oblanceolate, 16 to 30 cm. long, 6 to 12 cm. wide, sharply acuminate,
