STREPTOCARPUS 



polyantha, Hook. Hairy: as compared with S. Saun- 

 dersii, the leaf is smaller and the lis. bluer and borne 

 in a compound racemose panicle: corolla-tube curved, 

 shorter than the large, wide-spreading toothed pale blue 

 limb. Natal, Orange Colony. B.M. 4850. 



Galpini, Hook. f. Hairy: leaf ovate-oblong, obtuse, 

 entire : scapes several to many, glandular-pubescent: 

 fls. short and broad, being nearly or quite bell-shaped, 

 the limb broad and subequal, rich mauve, with a white 

 eye. Transvaal. B.M. 7230. G.C. III. 11:139. -Named 

 for Ernest E. Galpin, who discovered the plant. 



Wendlandii, Damman. Pig. 2433. Hairy, usually 

 bearing a rosette of very small lvs. at the base of the 

 radical one: leaf broad, often becoming 24x30 in., some- 

 times narrower, rounded at both ends, crenate-undu- 

 late, red-purple beneath: scapes several, forking, bear- 

 ing paniculate racemes : corolla-tube about 1 iu. long, 

 curved, pubescent, the limb large and oblique, with 

 broad entire lobes, the whole effect violet-blue and 

 whitish. Transvaal, Natal. B.M. 7447 (part of which 

 is copied in Fig. 2433). (4.0.111.22:275. On. 45, p. 511; 

 50, p. 394. J.H. III. 28:223. -Probably the finest species 

 yet introduced. 



bb. Leaves several, rising from the crown. 



Rexii, Lindl. Fig. 2434. Hairy: lvs. ovate-oblong, 

 6-9 in. long, short-stalked, obtuse, crenate: scapes sev- 

 eral, 3-8 in. tall, 1-fld. or rarely 2-nd.: fls. 2 in. long, 

 2-3 in. wide, the tube downy and nearly white, the large 

 spreading limb pale blue to purple. S. Afr. B.R. 

 14:1173. B.M. 3005. L.B.C. 14:1305. 



parvifldra, E. Mey. Soft-hairy all over except the co- 

 rolla: lvs. ovate, obtuse, sessile or nearly so, crenate, 

 appressed to the ground: scapes several, G— 10 in. tall, 

 reddish, bearing corymbose racemes: fls. small, the co- 

 rolla-tube about % in. long and purplish and curved, 

 the spreading broad limb nearly white and with orbicu- 

 lar lobes. Cape. B.M. 703G.

2435. Streptocarpus K 



lutea, Clarke. Lvs. erect, and elongate-oblong: fls 

 smaller and usually fewer, yellowish, the corolla-lobes 

 narrower and the tube relatively broader. Transvaal. 

 B.M. 6636 (as 8. parviflora). -Perhaps only a form of 

 5. parviflora. The two species were confused until 

 separated by Clarke in 1883. It appears that this plant, 

 rather than the true *S". parviflora, was one of the par- 

 ents of the hybrid S. Watsoni (see W. Watson, G.P. 3, 

 p. 609). 



AA. Streptocarpus hybrids, of garden origin. (For col- 

 ored pictures of modern hybrid types, see Gn. 

 29:545; 41:843; 50:1092.) 

 Kewensis (S. Itexiix pollen of S. Dunnii). Fig. 2435. 



"It has two or three large oblong or elongate-ovate 



STREPTOSOLEN 



bright green leaves, which, however, do not attain such 

 large dimensions as in S. Dunnii; flower-stems numer- 

 ous, and 6-8-fld., forming a tolerably compact mass of 

 fls.; corolla about 2 in. long and 1'4-1% in. in diam., of 

 a bright mauve-purple, striped with dark brownish pur- 

 ple in the throat." N. E. Brown. G. C. 111.2:247. I.H. 

 38:133. 



Watsoni (S. lutea x pollen of S. Dunnii). "The sin- 

 gle leaf is similar to but rather smaller than that of S. 

 Kewensis. It is exceedingly floriferous, having numer- 

 ous flower-stems, bearing 10-16 fls. about 1J4 in. long 

 and 1 in. in diam., of a bright rose-purple, with a white 

 throat striped with brownish purple." N. E. Brown. 

 G.C. III. 2:215. I.H. 38: 134. -One of the finest of gar- 

 den forms. Said to be sterile with its own pollen. 



Dyeri(S. Wendlandii x S. Dunnii). Leaf single, 2ft. 

 long and 15 in. wide, olive-green above and vinous pur- 

 ple beneath, soft-hairy : scapes 1-2 ft. or more tall, 

 bearing many long -tubular red-purple flowers. G.F. 

 8:5. — One of W. Watson's hybrids. 



Bruanti (S. RexiixS. polyantha). Fls. larger than 

 those of S. Rexii, 4-6 on each scape, mauve-blue, with 

 whitish yellow throat. 



5. biflbra, Duch., mentioned only iu horticultural literature, 

 and perhaps a garden form. It is of the S. polyantha type, 

 with several blue tls. — ,S'. MHoro-polydnthus, Duch., is a hy- 

 brid of S. biflora and S. polyantha, with several large light 

 blue fls. F.S. 23:2429.— S. caulescent. Vatke. One of the cau- 

 lescent species, with opposite elliptic-oblong entire hairy lvs., 

 the stem swollen, the tls. small ('■-. in. across) and pale lilac. 

 Trop. eastern Afr. B.SI. 6814— X. Q&rdeni, Hook. Allied to S. 

 Rexii: scapes several, bearing 2 nodding pale lilac fls., with 

 corolla 2J4 in. long. S. Afr. B.M. 4802. F.S. 12: 1214. -S. Greenii, 

 Hort., is a hybrid of S. Saundersii X pollen of S. Rexii: 

 dwarfer and more compact than S. Saundersii, the scapes 

 many-fld.: fls. pale lilac-blue. G.C. II. 17:303. Said to have 

 been the first hybrid Streptocarpus. Raised by Mr. Green, 

 Pendall Court, Surrey, England, iu the garden of Sir George 

 Macleay. — S. Kirhii. Hook. t\, is one of the caulescent section, 

 with opposite petiolate cordate -ovate subcrenate lvs., and 

 many-fld. clusters of pale lilac fls., the corolla being about % 

 in. long. Trop. eastern Afr. B.M. 07.82.— S. Lichtensteinensis, 

 Hort. Hybrid of S. WendlandiiXS. Watsoni. Lvs. 2, one pros- 

 trate and the other smaller and erect: fls. numerous, lilac-blue. 

 —S. mxdtiflbra, Hort. One of Laing's (England) types, a seed- 

 ling of S. Rexii. with several large bluish purple fls. with 

 darker lines in the throat. G.C. III. 18:211. I.H. 43, p. 87.

 peduncles). Lili&cece. Twisted Stalk. A genus of 

 3 or 4 species of perennial herbs, from the temperate

 ern states. B.B. 1:433. 



aa. Els. greenish white. 

 amplexifolius, DC. Rootstock short, stout: stem usu- 

 ally taller than 5. roseus: lvs. clasping, 3-6 in. long: 

 peduncles 1-2 in. long, usually 2-fld. : fls. about % in.
