HIBISCUS 



larger than calyx: caps, ovoid, pointed and hispid; 

 seeds glabrous Trop. Afr., Pacific islands, and Aus- 

 tral., and cult, in E. India. B.R. 381. -Offered in 

 S. Calif. 



8. aculeatus, Walt. Herbaceous perennial, not very 

 stout, 2-6 ft. tall, hispid all over but not tomentose 

 nor whitish: Ivs. roundish or roundish-ovate in out- 

 line, 3-5-lobed or -parted into linear or oblanceolate 

 cut or toothed blunt segms., the sinuses often rounded 

 and enlarging: bracteoles 10-12, linear, forking and 

 bristly, not so long as the calyx: fls. 3-4 in. across, 

 yellow or cream-colored with purple in the base, the 

 petals about 3 in. long and the calyx-lobes lanceolate 

 and bristly. S. C. south in sand, frequently near 

 swamps. Not hardy N. 



9. militaris, Cav. Herbaceous perennial, 4-6 ft., 

 strong-growing, glabrous or very nearly so: Ivs. rather 

 small, usually hastate (2 short lobes at base), the mid- 

 dle lobe ovate-lanceolate or triangular-lanceolate, long- 

 acuminate, equally crenate-toothed; upper Ivs. hal- 

 berd-form : bracteoles linear or awl-like, nearly or quite 

 half as long as the calyx: fls. 3-5 in. across, white, 

 blush or pale rose, purple-eyed: fr. inclosed in inflated 

 calyx; seeds hairy. Wet places, Pa. to Minn, and south 

 to the Gulf. B.M. 2385. A hardy and fine species. 

 Forms occur with Ivs. not lobed. 



10. coccineus, Walt. (H. speciosus, Ait.). Perennial 

 herb, green and glabrous throughout, glaucous, 3-10 

 ft. : Ivs. palmately lobed, or the lowest and sometimes 

 all of them palmately compound, the divisions long- 

 linear-lanceolate and remotely toothed: bracteoles 

 about 1% in. long, curved: fls. very large (5-6 in. 

 across), rose-red, the petals obovate and conspicuously 

 narrowed at the base; column of stamens very long. 

 Ga. south in swamps. B.M. 360. R.H. 1858, p. 575; 

 1866:230. This fine species is apparently not hardy 

 in the northern states, although there are reports that 

 plants have lived in the open in the neighborhood of 

 Philadelphia. The roots should be stored in a cellar 

 in winter. Plants have been carried over winter under 

 glass when used in hybridizing. 



11. grandifldrus, Michx. Perennial herb, tall and 

 stout (3-8 ft.), the terete reddish st. becoming glabrous: 

 Ivs. large, 3-lobed, the lobes ovate-acuminate or ovate- 

 oblong-acuminate, the side ones widely spreading, 

 blunt-toothed or even again lobed: bracteoles linear, 1 

 in.: fls. very large (6-8 in. across), white or rose, with 

 deeper eye. Ga., Fla. west, in swamps. Aside from 

 the large fls. and lobed Ivs., this is very like H. Moscheu- 



tos. It is doubtful 

 whether the true H. 

 grandiflorus is in 

 the trade. 



12. lasiocarpos, 

 Cav. Fig. 1832. 

 Perennial herb, to 6 

 ft. : st. : and Ivs. pu- 

 bescent: Ivs. ovate, 

 more or less cor- 

 date, acuminate, 

 toothed, often an- 

 gular or slightly 

 3-lobed, the upper 

 ones narrower: 

 bracteoles linear- 

 subulate and 

 bristly: fls. white 

 or pale rose with 

 darker center, the 

 petals 3-4 in. long: 

 caps, very hairy. 

 Swamps, Ky., west 

 and south. G. F. 

 1 : 426 (reduced in 

 Fig. 1832). 



1832. Hibiscus lasiocarpos. ( X M) 



HIBISCUS 



Var. calif 6rnicus (H. calif ornicus, Kell. H. lasio- 

 carpos var. occidentalis, Gray). Lvs. more uniformly 

 cordate: caps, less hairy; seeds papillate: marshy places 

 along San Joaquin and Sacramento Rivers. It is strong- 

 growing, to 7 

 ft., the st. -te- 

 rete or slightly 

 grooved above, 

 more or less 

 pubescent: Ivs. 

 distinctly cor- 

 date, ovate, 

 acute, shallow- 

 toothed and 

 not lobed, dull 

 ashy gray beneath : 

 involucre-bracts 

 hairy: corolla white 

 or rose, with a pur- 

 ple eye, 3-5 in. across : 

 caps, pubescent. Al- 

 though the name H. 

 californicus is com- 

 mon in the trade, it 

 is a question how 

 much of the stock, if 

 any, is this species. 

 Certainly some of it 

 is H. Moscheutos. From H. 

 Moscheutos this species is distin- 

 guished by its cordate ashy- 

 tomentose Ivs. and hairy-ciliate 

 involucre - bracts. The plant 

 known to the trade as H. cali- 

 Jornicus is hardy. 



13. Moschefttos, Linn. (H. 

 palustris, Linn.). SWAMP ROSE- 

 MALLOW. Strong-growing peren- 

 nial 3-8 ft., the terete st. pubes- 

 cent or tomentose: Ivs. mostly 

 ovate, entire in general outline 

 or sometimes shallowly 3-lobed 



at the top, crenate-toothed, very soft-tomentose beneath 

 but becoming nearly or quite glabrous above, the long 

 petiole often joined to the peduncle: bracteoles linear, 

 nearly or quite as long as the tomentose calyx: calyx- 

 lobes triangular-ovate; fls. very large (4-7-8 in. broad), 

 light rose-color: caps, globose-ovoid, glabrous. Marshes 

 along the coast from Mass, to Fla. and west to Lake 

 Michigan. B.M. 882. B.R. 1463; 33:7. Mn. 

 2:161. Gng. 2:227. F.S. 12:1233. R.H. 1907, p. 203 

 (as var. palustris). G.W. 6, p. 63. H. roseus, Thore, of 

 Europe, is considered to be a naturalized form of this 

 American species. R.H. 1879:10. One of the best of 

 the rose-mallows, thriving in any good garden soil. Of 

 easiest cult, and perfectly hardy. Blooms in Aug. and 

 Sept. The foliage is strong and effective. The most 

 generally cult, of the hardy herbaceous kinds. 



14. oculirSseus, Brit. CRIMSON-EYE ROSE-MAL- 

 LOW. Resembles H. Moscheutos: differs in fls. being 

 white with dark crimson center, calyx-lobes triangular- 

 lanceolate and nearly twice as long as broad, caps, 

 ovoid-conic and long-pointed. Marshes near the coast, 

 N. J. southward. 



15. incanus, Wendl. Much like H. Moscheutos, and 

 probably sometimes passing for it in the trade: Ivs. 

 smaller 'and narrower, ovate-lanceolate, rarely lobed, 

 serrate-toothed : fls. sulfur-yellow, pink or white with a 

 crimson eye: caps, ovoid and beaked, stellate-tomentose 

 and loosely hairy. Md. and south in swamps. Seems 

 to be hardy in the N. with a mulch protection. 



16. radiatus, Willd. (not Cav.). Woody shrub, 3-4 

 ft., armed on branches and petioles with small prickles: 

 Ivs. rather narrow, deeply palmately divided, 3-5- 

 lobed, or uppermost simple, the lobes broad-lanceo- 



1833. Hibiscus schizo- 



petalus. (X 1 A)
