AMERICAN PASSIFLORACEAE 539 This species presents such an assemblage of unusual characters that it seems best to place it in a monotypic section of Astrophea. The inflorescence is racemose, but the flowers are borne on long, very slender pedicels. The sepals, petals, and outermost corona filaments are very slender for Astrophea; the densely plumose threads constituting the inner filaments suggest the genus Dilkea. Section 5. Pseudoastrophea 327. Passiflora Candida (Poepp. & Endl.) Mast. Trans. Linn. Soc. 27: 629. 1871; in Mart. Fl. Bras. 13, pt. 1: 573. 1872. Tacsonia Candida Poepp. & Endl. Nov.

High-climbing shrub with stout tendrils, the stem terete or subangular, ferruginous-tomentulous; stipules soon deciduous; petioles stout, 2 to 2.5 cm. long, biglandular at apex, the glands sessile, ovate, 2.5 to 3 mm. long; leaves broadly ovate or ovate-oblong, 8 to 18 cm. long, 7 to 14 cm. wide, rounded, truncate, or short-acuminate at apex, rounded at base, remotely and obscurely callous-denticulate in upper half, penninerved (lateral nerves about 10 to a side), coriaceous, glabrous above, rufo-hirsutulous beneath on the prominent nerves and veins; peduncles solitary or in pairs, stout, clavate, 5 to 8 mm. long, tomentulous; flowers white, very fragrant; calyx tube broadly funnel-shaped, 2.5 to 3.5 cm. long, 1 to 1.5 cm. in diameter at the throat, tomentulous; sepals oblong, 3 to 4 cm. long, 1 to 1.5 cm. wide, fleshy; petals subequal to the sepals, membranous; corona filaments in 4 series, the outermost liguliform, 1.5 to 2.5 cm. long, verrucose at margin in upper half, bearing near middle of one side a short (about 1.5 mm.) appendage, the succeeding filaments filiform, diminishing from 4 to 1 mm. long; operculum borne about 7 mm. above base of tube, membranous, erect, 4 to 5 mm. high, lobulate and irregularly lacerate-fimbrillate; ovary narrowly ellipsoidal, rufo-tomentose.
