PASSIFLORA 



2483 



reddish purple band along each of the 3 midribs: 

 fls. yellowish, fragrant, small. Brazil. I.H. 15:544. 

 G.Z. 12:96. Interesting for its ornamental foliage.

6. maculiffilia, Mast. Notable for its spotted 

 or variegated foliage : branches slender and wiry, 

 puberulous: Ivs. short-stalked, roundish cordate, 

 3-nerved, with 3 shallow lobes at the truncate 

 apex, green and yellow-blotched above, purplish

 below, tall, branchy: Ivs. large, cordate, ovate- 

 acuminate, neither lobed nor toothed: fls. soli- 

 tary, the petals and sepals greenish, the corona 

 white, with zones of red-purple: fr. as grown in 

 S. Calif . described as oval, larger and more oblong

 in. or more across, the narrow petals deep red and wide- 

 spreading, the short, upright crown purplish; calyx 

 keeled on the lower side; fls. solitary, but the peduncles 

 usually 2 from an axil, becoming racemose on the ends 

 of the shoots: bracts 3: fr. described in cult, as cylindri- 

 cal-ovate, greenish vellow at maturity. Brazil. B.M. 

 2001. B.R. 285. L.B.C.1:84. Gn. 39:168. G.L. 24: 222. 

 A fine old species and a parent of various garden 

 hybrids. One of the best of the red-fld. passifloras. 

 Summer and fall. 



9. Raddiana, DC. (P. kermesina, Link & Otto). 

 Rather slender climber, glabrous: Ivs. shallow-cordate, 

 3-lobed and sparingly dentate, purplish beneath: fls. 

 solitary, with very narrow distinct sepals and petals of 

 a bright crimson-red, which are wide-spreading at first 

 but finally turning almost straight back; crown black- 

 purple, upright, with smaller whitish filaments inside. 

 Summer and fall. Brazil. B.M. 3503. B.R. 1633. G. 

 1:453. F.W. 1874:161. An old and well-known spe- 

 cies: said to prop, from cuttings of old well-formed 

 wood. P. Loudonii, Hort., is considered to be a hybrid 

 of this and P. racemosa. 



10. Watsoniana, Mast. Sts. wiry, purplish, with 

 leafy dentate stipules: Ivs. shallow-cordate, rather 

 broader than long, 3-lobed to the middle, with a few 

 teeth: peduncles 1-fld.; fls. about 3 in. across, the sepals 

 linear and shaded with violet ; petals also very narrow, 

 lilac ; crown of many rows of filaments, violet with bars 

 of white below the middle, the inner and shorter set 



deep violet. Probably Brazilian. G.C. II. 26:648, 649. 

 I.H. 36:74. Gn. 33:194. A.F. 6:571. Good grower. 



cc. Tube of fl. very short, thick or fleshy in substance. 



D. Sts. and branches strongly l^-angled or even winged: 



Ivs. simple. 



11. quadrangularis, Linn. GRANADILLA. Fig. 2770. 

 Tall strong cumber, glabrous: Ivs. ovate or round-ovate, 



cordate at base, mu- 

 cronate, entire, the 

 petiole with 2 or 3 

 pairs of glands: stip- 

 ules large: fl. large 

 (3-5 in. across) and 

 interesting, fragrant, 



2771. Passiflora edulis. (XJi) with ovate sepals and 

 petals (the former 



white within and the latter reddish), the crown 

 composed of 5 series of white-and-purple parti- 

 colored filaments, of which the outermost exceed the 

 floral envelopes: fr. oblong, 5-9 in. long, yellowish 

 green, pulpy and edible. Trop. Amer. B.R. 14. R.H. 

 1898, p. 569. Gn. 51, p. 313; 59, pp. 4, 7. G. 33:161. 

 Widely grown in the tropics, and variable, both as a 

 vine and for its edible frs. Frequent in collections of 

 economic plants in the N. It is a good cumber for 

 covering a greenhouse roof. Best results are secured if 

 the temperature does not fall below 50. The fr. ripens 

 in summer. The fls. usually need to be hand-pollinated 

 if fr. is wanted on house-grown plants. Var. variegate, 

 Hort. (P. variegata, Hort. P. aucubifolia, Hort.), has 

 foliage blotched with yellow. 



12. alata, Dry. St. winged: Ivs. glabrous, oval to 

 ovate, somewhat cordate at base, the margin often 

 undulate but otherwise entire, the petiole with 2 pairs 

 of glands: fl. 3-4 in. across, very fragrant, the interior of 

 the sepals and petals carmine; corona nearly or quite as 

 long as the envelopes, the numerous filaments parti- 

 colored with red, purple, and white: fr. yellow, ovoid- 

 pointed, about 5 in. long, very fragrant and one of the 

 most edible. S. Amer. B.M. 66. G.C. III. 15:19; 

 22:449-51; 43:187. R.B. 20, p. 104 (see R.H. 1902, 

 pp. 287-9, for taxonomic discussion). An excellent old 

 species, ripening its fr. in midsummer. It is very vari- 

 able, and is perhaps one form of a polymorphous spe- 

 cies including the granadilla. P. pheenicea, Lindl. 

 (B.R. 1603), P. brasiliana, Desf., P. onformis, Roem., 

 P. latifolia, DC., P. mauritiana, Thouars, and P. 

 mascarensis, Presl., are all considered to be forms of 

 this species. P. Lawsoniana, Hort., not Mast., is a 

 hybrid of P. alata and P. racemosa: Ivs. oblong-oval, 

 somewhat peltate, entire: fls. 3-4 in. across, brownish 

 inside, the corona with filaments in several series. 



13. Decaisneana, Hort., is perhaps a hybrid of P. 

 quadrangularis and P. alata: fls. bright carmine inside, 

 about 4 in. across; corona as long as or longer than the
