STBEPTOSOLEN 



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

 dersii, the leaf is smaller and the fls. 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. ll:139.-Named 

 for Ernest E. Galpin, who discovered the plant. 



W6ndlandii, Damman. Fig. 2433. Hairy, usually 

 bearing a rosette of very small Ivs. 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 in. 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). G.C. III. 22:275. Gn. 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: Ivs. ovate-oblong, 

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

 eral, 3-8 in. tall, 1-fld. or rarely 2-fld. : 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: Ivs. ovate, obtuse, sessile or nearly so, crenate, 

 appressed to the ground: scapes several, 6-10 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. 7036. 



2435. Streptocarpus Kewensis (X l /a). 



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

 smaller and usually fewer, yellowish, the corolla-l^bes 

 narrower and the tube relatively broader. Transvaal. 

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

 S. 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.F. 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. Rexiixpollen of S. Dunnil). Fig. 2435. 

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



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

 large dimensions as in . Dunnil ; flower-stems numer- 

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

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

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

 ple in the throat." N.JS.Brown. G. C. (11.2:247. 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. 

 Keivensis. It is exceedingly floriferous, having numer- 

 ous flower-stems, bearing 10-16 fls. about \% 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. 



S. biflbra, Duch., mentioned only in horticultural literature, 

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

 with several blue fls. -S. bifloro-polyanthus, Duch., is a hy- 

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

 blue fls. F.S. 23:2429. S. caulescens, Vatke. One of the cau- 

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

 the stem swollen, the fls. small (> in. across) and pale lilac. 

 Trop. eastern Afr. B.M. 6814. S. Gdrdeni, Hook. Allied to S. 

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

 corolla 2>4 in. long. S. Afr. B.M. 4862. F.S. 12:1214. S. Oreenii, 

 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, in the garden of Sir George 

 Macleay. S. Kirkii, Hook, f., is one of the caulescent section, 

 with opposite petiolate cordate - ovate subcrenate Ivs., and 

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

 in. long. Trop. eastern Afr. B.M. 6782. S. Lichtensteinensis, 

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

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

 S. multifldra, 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. 67.

STREPTOPUS (Greek, twisted stalk,- referringto the 

 peduncles). Liliacece. TWISTED STALK. A genus of 

 3 or 4 species of perennial herbs, from the temperate

 gonatum, from which it differs in having a 3-cleft style 

 and perianth in separate segments. Woodland plants 

 with slender branching stems: Ivs. alternate, thin, 

 clasping or sessile, prominently nerved: fls. rather 

 small, rose or white, nodding, slender-pediceled; soli- 

 tary or in pairs in the axils of the leaves: fr. a many-

 terminal flowers, while those of Streptopus are axillary. 



A. Fls. purple or rose. 



rdseus, Michx. Rootstock short, stout: stem 1-2 ft.

 long, mostly 1-fld.: fls. about % in. long: berry red, 

 Vi in. thick. May-July. Moist, rich woods in the north- 

 ern states. B.B. 1:433. 



AA. Fls. greenish white. 



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

 ally taller than S. roseus: Ivs. clasping, 3-C in. long: 

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

 long: berry red. May-July. Moist rich woods, north- 

 ern U. S. and Canada south to N. C. and 'New Mex.

STREPTOSOLEN (Greek, streptos, twisted, solcn, 

 tube, with reference to the form of the corolla-tube). 

 Solandcece. Lvs. on long petioles, ovate, acute at both

 pedicellate, in terminal corymbose panicles; calyx

 gated, widening above, spirally twisted below; petals 5,
