538 PASSIFLORACEiE. Passiflora. 



surrounded by a pulpy arillus. Embryo straight, in the centre of a 

 thin fleshy albumen. — Usually climbing herbaceous or shrubby 

 plants, with alternate mostly stipulate leaves. Flowers showy, 

 often involucrate. 



The inner series of floral envelopes, which we, following Lindley, consider as 

 the corolla, is by most botanists termed a second series of sepals, and thus Passiflora 

 is deemed apetalous. 



1. PA.SSIFLORA. Linn. ; Juss. gen. p. 397. 



Calyx urceolate or campanulate at the base, 5- (rarely 4-) cleft ; the throat 

 with a conspicuous often double or triple filamentous crown (transformed pe- 

 tals ?) ; the inner portion often a membranous disk. Petals 5 (rarely 4), 

 sometimes none. Stamens 5 (rarely 4), connate with the stipe of the ovary, 

 free or diverging at the summit. Anthers large, elongated, at length reversed 

 and turned outwards. Stigmas 3 (sometimes 4), large, clavate-capitate. 

 Berry pulpy, rarely somewhat membranaceous. — Herbs or shrubby plants, 

 climbing by tendrils. Leaves undivided or variously lobed : petiole often 

 bearing glands. Stipules occasionally wanting or minute. Peduncles axil- 

 lary, solitary or sometimes several together, mostly 1-flowered, articulated 

 above. — Passion-flower. 



§ 1. Pedicels 1-flowered, with a 3-bracteolate involucre near the floicer : ten' 

 drils simple, from the same axils. — Granadilla, DC. 



1. P. incarnata (Linn.) : leaves deeply 3-lobed, membranaceous, gla- 

 brous, or somewhat pubescent beneath, serrate ; the lobes ovate-lanceolate, 

 mostly acuminate ; petioles with 2 glands near the summit ; stipules minute ; 

 involucral bracts obovate, glandular ; ovary villous-canescent. — Linn. ! spec.

In dry soil, Virginia ! to Florida ! and Arkansas ! May-July. — H Root 

 sometimes tuberiferous. Stem often climbing to the height of 20 or 30 feet. 

 Flowers large, on long pedicels. Segments of the calyx cuspidate below 

 the summit. Petals oval-oblong, white. Crown triple ; the 2 outer series 

 composed of long radiating filaments, purple, with a nearly white band ; the 

 inner of short erect flesh-colored rays. Berry as large as a hen's egg, oval, 

 glabrous, with a leathery coat, pale-yellow when ripe, eatable ; sometimes 

 with 4 placentas and as many styles. 



§ 2. Pedicels 1-floivered ; tvith a simple tendril from the same axils : involu- 

 cre none, or minute. — Cieca, DC. 



2. P. lutea (Linn.) : leaves broad, somewhat cordate at the base, obtusely 

 3-lobed at the summit, entire, glabrous, not glandular ; the lobes short and 

 rounded, mucronulate ; petiole glandless ; stijiailes minute ; pedicels mostly 

 geminate ; petals much narrower than the sepals. — Linn. ! spec. 2. p. 958 ;
