HIBISCUS 



HIBISCUS 



1487 



1834. Hibiscus Rosa-sinensis. (XH) 



late and serrate; stipules linear: bracteoles 8-10, linear, 

 forked: fls. axillary and solitary, yellow with crimson 

 center; calyx not glandular. India, Java. Widely cult. 

 in tropics. Var. fldre-purptlreo, Hook., has rose-purple 



fls. B. M. 5098. 

 Var. Lindlei (H. 

 Lindlei, Wall.) has 

 deep purple fls. 

 B.R. 1395. 



17. cisplatinus, 

 St. Hil. Bushy, 

 3-5 ft.: sts. gla- 

 brous but prickly: 

 Ivs. deltoid - lan- 

 ceolate or deltoid- 

 ovate, 3-lobed, 

 coarsely toothed, 

 sparsely hairy on 

 the veins: fls. soli- 

 tary, 4-5 in. 

 across, light pink, 

 with darker color 

 in the eye and 

 sometimes darker 

 on the margins. 

 Brazil (this side the Platte River, whence apparently the 

 specific name). R.H. 1898:480. Gng. 7:50. Little 

 known in this country. It is a handsome late fall 

 bloomer, and may be planted out in summer. It seeds 

 freely, and these, sown as soon as ripe, will give blooming 

 plants for the following fall. 



18. heterophyllus, Vent. Tall shrub, glabrous except 

 on inn. and very young shoots, the branches often 

 prickly: Ivs. varying from linear to lanceolate and 

 elliptic-oblong and from entire to 3-lobed, 5-6 in. long, 

 usually serrulate and sometimes white beneath: fls. 

 large (3-4 in. long), white with a deep crimson eye, the 

 calyx tomentose: caps, hairy; seeds glabrous. Austral.; 

 intro. in S. Calif., where it is a free and showy bloomer. 



19. Hamabo, Sieb. & Zucc. Shrub, 6-10 ft. high, 

 closely pubescent: Ivs. roundish, with an abrupt short 

 point, irregularly shallowly toothed, or wavy, white 

 tomentose beneath and green or grayish hairy above: 

 involucre of scales united at the base: fls. solitary in 

 the upper axils, large, yellow, with a darker base, about 

 3 in. across. A Japanese species offered by importers 

 but not yet tested in this country, and probably not 

 hardy south of the southern-middle states. Said to be 

 cult, in Japan. 



20. elatus, Swartz (Paritium elatum, Don). MOUN- 

 TAIN MAHOE. Spreading small tree: Ivs. round-cordate, 

 short-cuspidate, entire, hoary beneath: involucre 

 deciduous with the calyx, 8-10-toothed : fls. 4 in. long, 

 opening primrose-color in the morning, then changing, 

 as the day advances, to orange and deep red: seeds 

 hairy. W. Indies. This species, the next, and probably 

 others, yield the Cuba bast, used for tying cigars and 

 for other purposes. Lvs. and shoots medicinal: wood 

 durable. 



21. tiliaceus, Linn. (Paritium tiliaceum, Juss.). 

 Round-headed tree, 20-30 ft. high, sometimes a tall 

 shrub: Ivs. round-cordate and short-acuminate, entire 

 or obscurely crenate, hoary beneath: involucre per- 

 sistent with the calyx, 10-toothed or -cut: fls. 2-3 in. 

 long, yellow: seeds glabrous or very nearly so. Fla. 

 keys and W. Indies, but widespread in tropics and 

 probably of Old World origin. Sprouts from the base 

 if frozen. 



22. calycinus, Willd. (H. chrysdnthus, Hort.). Small 

 slender shrub: pubescent: Ivs. long-stalked, round- 

 cordate, somewhat 3-5-angled and 5-7-nerved, cre- 

 nate, hairy or velvety: stipules subulate: fls. on axillary 

 peduncles which are shorter than the petioles, large, 

 yellow, with a dark center: involucre bracts 5, bristle- 



pointed: caps, tomentose. S. Afr. To be grown 

 indoors, but may be planted out in the summer with 

 good results. Probably valuable for permanent plant- 

 ing in the extreme S. 



23. schizopetalus, Hook. f. Fig. 1833. Tall gla- 

 brous shrub with slender drooping branches: Ivs. 

 ovate-elliptic, toothed: bracteoles minute: fls. pendu- 

 lous, on long jointed peduncles, red or orange-red, the 

 recurved petals beautifully and deeply cut; calyx 

 tubular; stamens long-exserted : fr. long, bearing 

 smooth seeds. E. Trop. Afr. B.M. 6524. F.S. 23:2397, 

 2398. G.Z. 25, p. 241. A beautiful species, for the 

 warmhouse; grown in the American tropics. 



24. liliifldrus, Cav. (H. Genevii, Bojer). Shrub, gla- 

 brous: Ivs. petioled, ovate, 24 in. long, entire or cre- 

 nate, often few-toothed at apex, obtuse or acute, 

 rounded at base, the young ones sometimes deeply 

 parted: bracteoles 5, linear, connate at base: fls. soli- 

 tary in upper axils, long-peduncled, bright red; sepals 

 1^2 in. or less long, lanceolate, connate above the mid- 

 dle; corolla funnel-shaped; stamens equaling corolla 

 or somewhat exserted. Mauritius and Seychelles 

 Islands. B.M. 3144. An excellent glasshouse spe- 

 cies, of several 



varieties. 



25. Arnottia- 

 nus, Gray (H. 

 Fauriei, Leveil.) 

 Tree, 20-30 ft.: 

 Ivs. large, ovate, 

 short-acumi- 

 nate, entire, 3- 

 nerved, stiffish, 

 shining : brae- 

 teoles 5-7, tri- 

 angular to lan- 

 ceolate: fls. axil- 

 lary and soli- 

 tary, very large, 

 white, some- 

 times with pink- 

 ish veins; calyx 

 tubular, 5 - 

 toothed; sta- 

 mens long - ex- 

 serted, white or 

 red. Hawaii; 

 cult, there, and 

 intro. in S. Calif. 



26. Denisonii, 

 Burb. Small 

 glasshouse 

 shrub, flowering 

 when very small, 

 glabrous: Ivs. 

 thick and rather 

 stiff, slender- 

 stalked, elliptic- 

 ovate, entire or 

 obscurely crenu- 

 late, acuminate, 

 dull green : fls. 

 terminal, large, 

 white, 4-5 in. 

 across. Nativity 

 unknown, but 

 intro. from Aus- 

 tral. F.M.1876: 

 232. G.Z. 22: 

 217. A good 

 greenhouse 

 plant, requiring 

 warm tempera- 

 ture; apparently 



little grown. 183S. Hibiscus syriacus. (XH)
