 Parritse, Mast. Lvs. deeply 3-loberl, glabrous above 

 and pilose beneath, the lobes narrow and entire; stipules 

 entire, subulate-acuminate: fl. "with a long and slender 

 tube, glabrous, swollen at the base ; sepals winged and 

 with points, rosy-orange; petals oblong and flat, shorter 

 than the sepals, orange; corona double, the outer row 

 of tooth-like projections. Colombia. G.C. II. 17:225. 

 I.H. 35:41. — Named for Senor Parra, through whom it 

 was introduced. 



aa. Fls. scarlet or rose-colored. 

 B. Bracts beneath the flower not united. 

 c. Lvs. simple or not lobed. 

 insignis, Mast. Pilose: lvs. ovate-lanceolate, sub- 

 cordate, dentate, rugose or blistered above and red- 

 downy beneath, the stipules dissected: fl. 

 about 6 in. across, violet, rose or crimson; 

 tube cylindrical, swollen at the base, downy j 

 sepals about twice longer than the tube, 

 lance-oblong, spurred at the end; petals simi- 

 lar in shape, obtuse; corona of one series 

 of short threads, blue and white. Probably 

 Peruvian. G. C. 1873:1113. F. S. 20:20S3-4. 

 B.M. 60C9. 



CO. Lvs. S-lobed or divided. 

 D. Foliage glabrous at maturity. 

 Van Volxemii, Hook. Fig. 2457. Stems 

 slender and slightly pubescent: lvs. cordate- 

 ovate in outline, deeply 3-lobed, the lobes 

 long-lanceolate-acuminate, serrate: fls. 5-7 

 in. across, bright red with short green 

 calyx-tube that has a swollen base, the acute 

 calyx-lobes green externally; corona an in- 

 conspicuous toothed rim. Colombia. B.M. 

 5571. G.C. 1806:171. -Probably the best known 

 species and handsome, but less showy than 

 some others. 



Jamesoni, Mast. Lvs. sub-orbicular, 3-lobed, gla- 

 brous: fl. large, bright rose or cherry red, with a cylin-

 Exoniensis, Hort. (hybrid of T. Van Volxemii and T. 

 mollis sima). Fig. 2458. Lvs. downy, cordate, ovate- 

 oblong, divided nearly to base into 3 lanceolate, serrate 

 segments: fls. 4J^-5 in. across; sepals brick red out- 

 side, brilliant rose pink within; throat violet; tube 

 white inside, 2% in. long. Resembles T. Van Volxemii 

 in having peduncles as long as lvs.: linear stipules: 

 free downy bracts, filamentous corona near base of tube 

 and violet color of throat. — Resembles T. mollissima in 

 having downy lvs., long flower tube, color of fl. and 

 aristate sepals. 



bb. Bracts beneath the flower more or less united. 

 C. Leaf-lobes short and obtuse. 



manicata, Juss. Pubescent, lvs. broad-ovate to or- 

 bicular-ovate in outline, about 4 in. long, the oblong 

 obtuse serrate lobes reaching to the middle of the blade: 

 fl. 4 in. across, bright scarlet; tube Vi in. long, inflated 

 and ribbed at the base; corona double, the outer series 

 composed of blue hairs. Colombia and Peru. B.M. 

 G129. — P. ignea, Hort., is a form of this species. 



cc. Leaf-lobes long-acute. 



mixta, Juss. Glabrous or somewhat pubescent: lvs. 

 orbicular-ovate, thick, 3-lobed to the middle, the lobes 

 long-acute and serrate: fl. 3-4 in. across, rose-pink, the 

 oblong sepals not equaling the green scarcely saccate 

 tube; corona a short multiple rim or disk. Andes. 



mollissima, HBK. Pubescent: lvs. cordate-ovate in 

 outline, very pubescent beneath, the lobes extending 

 nearly to the base of the blade and ovate-lanceolate in 

 shape aud serrate, the stipules laeiniate: fl. about 3 in. 

 across, rose-color, the green tube exceeding the sepals 

 and swollen at the base; corona a short rim. Andes. 

 B.M. 4187. B.R. 32:11. F.S. 2:78.-5'. tubiflora, offered 

 in California, is said to be similar to this, but of deeper 

 shade. 



Smythiana, Hort. Seedling of T. mollissima or hy- 

 brid with it, with very brilliant orange-scarlet or rosy- 

 crimson fls. G.C. III. 12:704. 



T. Buchanani, Lem. See Passiflora vitifolia, p. 1222. I.H. 

 14:519. — T. floribuuda was once advertised in the American 

 trade, hut it was probably not the T. floribuuda, Masters, of 

 Colombia.— T. pinnatistipula, Juss. Resembles T. mollissima, 

 but the bracts are free: stipules pinnatisect: fls. rose-colored.
