544 FIELD MUSEUM OF NATURAL HISTORY BOTANY, VOL. XIX 7600 (EG, N, Y), 7622 (B, BG), 7642 (EG, N). Corembyne River, Im Thurn (K, type of P. eminula); Jenman 327 (BG).

Rio de Janeiro: Quinta de Sao Christovao, Glaziou 13912a (K, P). No differences are discernible between P. eminula and P. costata. Masters states that P. costata is "glaberrima," but some of the specimens he cites, such as the "Wullschlagel" collection, have the leaves and stem finely puberulous, similar to the type of P. eminula. This fine puberulence differs in degree in the material cited above, being more prominent in the Guiana specimens than in the Brazilian ones. Passiflora hydrophila, based upon a Rio Negro plant, I know only from the description and detailed illustration accompanying it, but it unquestionably is the same as P. costata. Type material of P. inundata I have compared directly with the type of P. costata, and find no differences other than the slightly larger flowers and longer peduncles and petioles of the former. Barbosa gives as a local name "maracuya do igapo." this is known as "marcusa." In Surinam 332. Passiflora faroana Harms, Notizbl. Bot. Gart. Berlin 10: 809. 1929. Subscandent shrub, glabrous throughout except the ovary; petioles 5 to 10 mm. long, biglandular at junction with blade, the glands scarlike; leaves ovate or broadly ovate-oblong, 4 to 10 cm. long, 3 to 6 cm. wide, obtuse and sometimes emarginate at apex, rounded at base, subcoriaceous, conspicuously reticulate-veined and sublustrous on both surfaces; peduncles solitary, 1 to 5 mm. long at anthesis, up to 15 mm. long in fruit, corrugate; flowers white, redmaculate; calyx tube funnelform, about 1 cm. long; sepals linearoblong, 1.5 cm. long, 4 mm. wide, carinate distally; petals linear, slightly shorter than the sepals, about 2 mm. wide; corona filaments in 2 well defined and several poorly defined series, the outermost narrowly linear, 1 cm. long, falcate-dilated above middle and vermcose along margin, those of the second series adjacent to the preceding, liguliform, about 2 mm. long, the succeeding filaments borne in 3
AMERICAN PASSIFLORACEAE 545 or 4 irregular rows at middle of tube; operculum erect, below middle of tube, about 3 mm. high, borne just cleft in upper third into broadly clavate segments; ovary ovoid, hexagonal, puberulent; fruit subglobose, 2 cm. in diameter sparingly puberulent; seeds obovate, 5 mm. long, 3 mm. wide, coarsely reticulate. TYPE LOCALITY: Campina do Jupiry, near Lago de Faro, State of Para, Brazil. DISTRIBUTION: Known only from the type locality, in lower Amazonian Brazil. BRAZIL: Para: Campina de Jupiry, near Lago de Faro, Ducke 825 (B, type, K, N). Campos de Tigre, Faro, Ducke 675 (B, Bo, K, P, N). Excellent material deposited in the United States National Herbarium by Ducke permits a more detailed diagnosis of the flowers and fruit than that given by Harms. Although the foliage is suggestive of P. sclerophylla and P. phaeocaula, the multiple corona indicates probably that it is more closely related to P. costata. 333. Passiflora sclerophylla Harms, Notizbl. Bot. Gart Berlin 6: 347. 1917. Scandent shrub, 1 to 2 meters high, the branches glabrous or the younger puberulent; petioles 5 to 10 mm. long, biglandular at apex; leaves suborbicular, oval, obovate, or oblong, 4 to 7 cm. long, 3 to 7 cm. wide, rounded, emarginate, or subacute at apex, rounded at base, reticulate-veined (veins elevated beneath), thick-coriaceous, glabrous and shining above, short-villosulous beneath; peduncles solitary in the axils or in 2's or in 3's, 1 to 1.5 cm. long, appressed-pubescent; calyx tube broadly funnel-shaped, nearly 1 cm. long, 1 cm. in diameter at the throat; sepals narrowly oblong, 2.3 to 2.5 cm. long, obtuse; petals lanceolate, 1.8 to 2 cm. long; corona filaments in 2 series, the outer about 2 cm. long, laterally compressed, geniculate at middle, the upper half narrowly linear-attenuate, verrucose along margin, the inner filaments filiform, about 3 mm. long; operculum cleft nearly to the base into linear-clavate segments about 3 mm. long; ovary narrowly oblong, densely ferruginous-tomentose. TYPE LOCALITY: "Guyana, Venezuela: Roraima." DISTRIBUTION: Southern Venezuela and southern British Guiana. BRITISH GUIANA: Mt. Roraima, Uk 8667 (B, type, Go, Ut)- Im Thurn 110 (EG, EM, K, N); Schomburgk 986 (B); G. H H Tale 323 (Y).
