416 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX nerved, subcoriaceous or membranous, often glaucous beneath; peduncles 1.5 to 3 cm. long, slender; bracts cordate-ovate or cordatelanceolate, 1.5 to 2.5 cm. long, 1 to 1.5 cm. wide, acute at apex, mucronulate, sessile, verticillate, thin-membranous, glaucous; flowers up to 9 cm. wide (expanded); calyx tube campanulate; sepals oblonglanceolate, up to 1.5 cm. wide, obtuse, ecorniculate, green without, white within; petals about a fourth longer than the sepals, about 1 cm. wide, white; corona filaments in 4 or 5 series, those of the 2 outer series terete, equaling or slightly longer than the petals, white at tips, followed by a wide band of blue, the lower three-quarters alternately banded with red and white, the 2 or 3 inner series consisting of minute tuberculiform filaments barely 1 mm. long; pperculum membranous, about 2 mm. high, with numerous dentiform processes at margin; nectar ring a low ridge; limen tubular, about 6 mm. high, closely surrounding base of gynophore, flaring at margin; ovary ovoid, glabrous. TYPE LOCALITY: Organ Mountains, in southeastern Brazil (type collected by Lobb). ILLUSTRATIONS: Bot. Mag. 69: pi. 4009; Fl. des Serres 2: pi. 10. April, 1846; Gard. Chron. III. 32: 15. /. 8. 1902. DISTRIBUTION: Southeastern Brazil. BRAZIL: Martins (Brux). Villa Thuret, collector uncertain, in 1889 (A). Rio de Janeiro: Theresopolis, Erode 9493 (B). Sao Paulo: Apiahy, Puiggari in 1883 (P, type of P. paulensis). Parana: Curityba, cultivated, Dusen 8809 (B, BM, Gen, N, S). Ponta Grossa, Dusen 10928 (S). Ypiranga, Dusen 6672 (S), 12128 (S); Jonsson 834a (S). Jaguariahyba, Dusen 17463 (B, S). From P. Jileki, the only Brazilian species of this immediate relationship, P. actinia is readily distinguished by the shorter, oval, obtuse leaves. It is sometimes confused with P. sidaefolia (P. tetraden Veil.), but the leaves of that species are 3-lobed, though sometimes obscurely so, and the bracts are different. Passiflora paulensis appears to be a form of this with smaller, thinner leaves and smaller flowers. 254. Passiflora canescens <strong>Killip</strong>, sp. nov. Herba scandens; caulis glaber; stipulae semi-oblongae vel subreniformes; petioli 6-glandulosi, glandulis filiformibus, subcurvatis; folia cordato-ovata vel ovato-lanceolata, subcoriacea, supra glabra, subtus dense et minute cinereo-puberula; bracteae cordato-ovatae; sepala petalaque oblonga, subaequalia, sepalis extus dense et minute
AMERICAN PASSIFLORACEAE 417 puberulis, late carinatis; coronae filamenta 3-4-seriata, extima quam altera longiora; operculum erectum, minute fimbrillatum ; ovarium ovoideum, cano-tomentosum. Herbaceous vine; stem subterete, glabrous, dark brown; stipules semi-oblong or subreniform, 2 to 2.5 cm. long, 8 to 10 mm. wide, entire, subcoriaceous, persistent; petioles 2.5 to 3.5 cm. long, stout, bearing 3 pairs of filiform, slightly curved glands 1.5 to 2 mm. long; leaves cordate-ovate or ovate-lanceolate, 9 to 11 cm. long, 5 to 6.5 cm. wide, obtuse, subpeltate, cordulate, entire, 3-5-nerved, subcoriaceous, bright green, glabrous, and conspicuously reticulate above, densely puberulent beneath with a minute, soft, grayish white indument, which likewise clothes the base of the tendrils and the peduncles, the under side of the stipules, the inside of the bracts, and the outside of the sepals and calyx tube; peduncles in pairs, slenderer than the petioles, 3.5 to 4 cm. long; bracts cordate-ovate, about 1.5 cm. long and 1 cm. wide, obtuse, mucronulate, membranous, borne at the apex of the peduncle; calyx tube patelliform, about 5 mm. long, 1 cm. wide at the throat; sepals oblong, 1.5 to 2 cm. long, 7 to 9 mm. wide, obtuse, dorsally broad-keeled, the keel up to 4 mm. wide? terminating in a short horn; petals oblong, subequaling the sepals, obtuse, white, minutely spotted with red; corona in 3 or 4 series, filiform, outermost filaments about 1.5 cm. long, radiate, purplish(?), the succeeding ones subulate, 1 to 2 mm. long, erect; operculum about 1.5 mm. high, erect, minutely fimbrillate; limen membranous, about 2 mm. high, closely surrounding the gynophore; ovary ovoid, white-tomentose. Type in the U. S. National Herbarium, No. 1,593,569, collected at Serra do Caraca, Municipio Santa Barbara, State of Minas Geraes, Brazil, April 13, 1933, by Mello Barreto (No. 874; Herb. Jard. Bot. Betto Horizonte No. 5465). This plant is remarkable for its dense, fine indument, which gives a decided ashy color to the under side of the leaves and to the outside of the flowers. The sepals are broadly keeled, almost as broadly as in P. Parritae, a species of the wholly unrelated subgenus Tacsonia. 255. Passiflora praeacuta Mast. Bot. Jahrb. 8: 220. 1887. Stem terete or subquadrangulate, glabrous below, pilose above; stipules foliaceous, obliquely ovate, 1.5 to 2.5 cm. long, 0.7 to 1 cm. wide, acuminate, aristate, glandular-serrulate; petioles 2 to 3 cm. long, pilose, bearing 4 to 6 curved, filiform glands 2.5 to 4 mm. long; leaves ovate-lanceolate, 10 to 16 cm. long, 6 to 8 cm. wide,
