entire or with a few teeth in the bottom of the sinus, the 

 under surface slightly glaucous: fl. about 3 in. across, 

 the petals and sepals lilac-pink inside (sepals ending in 

 a long spur), the numerous filaments of the corona 



2773. Passiflora (Tacsonia) Van 

 Volzemii. Central leaflet broader 

 than common. ( X H) 



white-tipped and barred with violet and white. Brazil. 

 B.M. 6997. R.H. 1885:468. G.W. 14, p. 151. 



24. caerillea, Linn. Fig. 2772. Slender, but a strong 

 grower, glabrous and somewhat glaucous: Ivs. divided 

 nearly to the petiole into 5 lanceolate or lance-elliptic 

 entire sharp-pointed segms. of which the 2 lower ones 

 are sometimes again lobed: fl. 3-4 in. across, slightly 

 fragrant, greenish white, the sepals tipped with a short 

 point, the rays of the corona in 2 series, blue at the 

 tip, white in the middle and purple at the base, the 

 styles light purple. Brazil. B.M. 28. Gn. 31, p. 421;

 The commonest of passion-flowers in American green- 

 houses, and now represented by several 



named forms and hybrids. It can be grown 

 in the open in the S. and in Calif, as far 

 north as San Francisco. Var. grandiflora, 

 Hort., is only a somewhat larger-fld. form. 

 Constance Elliott (P. caeriilea var. dlba), 

 is a white-fld. fragrant form. G.C. III. 

 43:186. Gn. 31:420. There are hybrids 

 with P. Raddiana, P. racemosa, P. alata, 

 and others. P. caerulea grows readily from 

 seeds. 



II. TACSONIA, the hypanthium or calyx-tube 



long (}4in. long and usually much more). 



A. Fls. orange or rosy orange. 



25. Parritae, Bailey (Tacsonia Pdrri- 

 tse, Mast.). Lvs. deeply 3-lobed, glabrous 

 above, pilose beneath, 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 ("better known as Parrita"), through 

 whom it was intro. 



AA. Fls. scarlet or rose-colored. 



B. Bracts beneath thefl. not united. 



c. Lvs. simple or not lobed. 



26. insignis, Hook. (Tacsonia insignis, Mast.). 

 Pilose: Ivs. ovate-lanceolate, subcordate, 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; 

 sepals about twice longer than the tube, lance-oblong, 

 spurred at the end; petals similar in shape, obtuse; 

 corona of one series of short threads, blue and white. 

 Probably Peruvian. G.C. 1873:1113. F.S. 20:2083, 

 2084. B.M. 6069. 



cc. Lvs. 3-lobed or divided. 

 D. Foliage glabrous at maturity. 



27. Van Volxemii, Triana & Planch. (Tacsonia Van 

 Volxemii, Hook.). Fig. 2773. Sts. slender and slightly 

 pubescent: Ivs. 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 inconspicuous toothed rim. 

 Colombia. B.M. 5571. G.C. 1866:171. G.Z. 9:144. 

 Less showy than some others, but a well-known species. 



28. Jamesonii, Bailey (Tacsonia Jdmesonii, Mast.). 

 Lvs. suborbicular, 3-lobed, glabrous: fl. large, bright 

 rose or coral-red, with a cylindrical tube 4 in. long: fr. 

 said to be green at maturity, oval. Peru. 



DD. Foliage downy beneath at maturity. 



29. exoniensis, Hort. (hybrid of P. Van Volxemii 

 and P. moUissima). Fig. 2774. Lvs. downy, cordate, 

 ovate-oblong, divided nearly to base into 3 lanceolate, 

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

 side, brilliant rose-pink within; throat violet; tube 

 white inside, 2^ in. long. Resembles P. Van Volxemii 

 in having peduncles as long as Ivs., linear stipules, free 

 downy bracts, filamentous corona near base of tube 



2774. Passiflora (Tacsonia) exoniensis.
