SCHIZANTHUS (Greek, split and flower; from the 

 incised corolla). Solanacese. BUTTERFLY FLOWER. 

 Erect half-hardy annual herbs, more or less glandular- 

 viscid, grown outdoors and also in the greenhouse for 

 bloom. They can be trained into immense pot subjects. 



Leaves frequently pinnatisect, the segms. incised or 

 dentate: cymes terminal and open: fls. incised, showy 

 and variously colored; calyx deeply 5-cleft, almost 5- 

 parted, the lobes linear; corolla-tube short or elongated, 

 cylindrical, the limb spreading, oblique, somewhat 2- 

 h'pped, laciniate; perfect stamens 2, exserted; disk in- 

 conspicuous; ovary oblong, 2-celled: caps, membrana- 

 ceous-chartaceous ; seeds numerous. About 7 species, 

 all from Chile. These choice plants are of easy cult, in 

 any. good garden soil. They are also useful as pot- 

 plants for spring flowering, the seed being sown in 

 early fall and the plants kept in a light house and given 

 plenty of root-room as they need it. There is a strain 

 offered in trade under the name of S. hybridus, Hort., 

 which is not readily placed botanically. It does not 

 appear to be specific in rank and apparently consists of 

 a series of large-fld. garden hybrids. It is offered in 

 several variations. 



A. Corollas-tube as long as the calyx; stamens short-exserted. 

 B. Middle segm. of the anterior Up of the corolla 



notched at summit. 



rettlsus, Hook. St. 2 ft. high: Ivs. pinnatisect, with 

 the segms. entire, dentate, or pinnatifid: fls. in the type 

 deep rose, with the large middle segm. of the upper h'p 

 orange except at the tip; the lateral segms. of the pos- 

 terior lip falcate, acute, linear, longer than the middle 

 segm. B.M.3045. B.R. 1544. G. 5:361; 23:35. G.M. 

 51:416. H.F. 1:136. Var. albo-maculatus, Hort., is a 

 form with white -spotted fls. Var. albus, Hort., has 

 the fls. white with the middle segm. of the upper lip 

 suffused with yellow. Gn. W. 17:458. Var. lilacinus, 

 Hort., has lilac fls. Var. nanus, Hort., a dwarf form, is 

 offered in the trade. Var. trimaculatus, Hort. (S. 

 trimaculatus, Hort.), has the fls. purple-crimson with 

 3 distinct golden yellow spots bordered with bright 

 purple. R.B. 32, p. 61. 



BB. Middle segm. of the anterior lip not notched 



at apex. 



Grahamii, Gill. Lvs. 1-2-pinnatisect; segms. entire 

 or dentately pinnatifid: fls. typically lilac or rose, with 

 the middle half of the middle segm. of the anterior lip 

 yellow or orange; the lateral segms. of the posterior lip 

 falcate, linear, acute, shorter than the middle segm. 

 B.M. 3044. R.H. 1843:529. H.F. 1:136. Var. albus, 

 Hort., has white fls. Var. carmineus, Hort., has carmine 

 fls. Var. carneus, Hort., is offered in the trade and has 

 flesh-colored fls. Var. lilacinus, Hort., has lilac fls. Var. 

 niveus, Hort., has pure white fls. Var. roseus, Hort., 

 has rose-colored fls. 



AA. Corolla-tube shorter than the calyx; stamens long- 

 exserted (not noticeably so in S. wisetonensis). 



wisetonensis, Hort. (S. pinnatus x S. Grahamii). 

 Apparently intermediate between the two parents, the 

 fl. resembling that of the latter parent in outline, the 

 corolla-tube seemingly shorter than the calyx, the 

 stamens usually rather short-exserted, the fls. vary in 

 color from white through bluish and pink to carmine- 

 brown, the midlobe of upper lip often suffused with 

 yellow. A hybrid of garden origin now very generally 

 cult. G. 25:161; 28:225; 33:351. G.M. 43:332; 53: 

 164. Gn.M. 13:76. Gt. 53, p. 326; 54:1544. G.W. 6, 

 pp. 38, 39. J.H. III. 64:321. R.B. 27:169. C.L.A. 

 19:166. F.E. 23:646. Var. compacta, Hort., is only 

 a more compact form than the type. 



pinnatus, Ruiz & Pav. (S. porrigens, Graham. S. 

 Priestii, Paxt.). Fig. 3569. The most variable of the 

 species, with many horticultural forms distinguished 

 by height of st. and color-markings of the fls. Typically 

 2 ft. high: Ivs. 1-2-pinnatisect; the segms. entire, den- 

 tate or incisely pinnatifid: fls. varying in depth of color, 

 the lower lip usually violet or lilac; the upper paler, its 

 middle section with a yellow blotch at its base and 

 spotted with purple or violet. B.M. 2404; 2521. B.R. 

 725; 1562 (as var. humilis). Gng. 

 12:613. G.W. 3, p. 497. The plant 

 known horticulturally and in trade- 

 lists as S. grandiflorus, Hort., and 

 variations, undoubtedly belongs here. 

 Var. albus, Hort. 

 (S. grandiflorus albus, 

 Hort.), has fls. 

 slightly larger than 

 the type, white or 

 yellowish. Var. can- 

 didissimus, Hort., 

 has pure white fls. 

 Var. compactus, 

 Hort., is a compact 

 form similar to var. 

 nanus, and offered in 

 several forms in the 

 trade. Var. lilacinus, 

 Hort., has lilac fls. 

 Var. nanus, Hort., is 

 dwarfer than the 

 type, offered in sev- 

 eral colors in the 

 trade. Var. niveus, 

 Hort., has pure white 

 fls. Var. oculatus, 

 Hort. (S. grandiflorus 

 oculatus, Hort.), has 

 a purplish black 

 blotch surrounded 

 with yellow at the 

 base of the middle 

 segm. of the upper 

 h'p or with the typi- 

 cal yellow portion 

 dotted with small 

 dark purple spots. B.H. 1862:451. H.F. II. 2:264. 

 Var. papilionaceus, Hort., has a central coloring some- 

 what as var. oculatus, with the general color of the fl. 

 marbled in various shades. Var. roseus, Hort., has 

 rose-colored fls. Var. tigridioides, Hort., is also cult.
