HIBISCUS 



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. 



— 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.

Reasoner. Evergreen. Sprouts from the base if frozen.

17 heterophyllua, Vent. Tall shrub of Australia, int. 

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

 glabrous: lvs. 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 tomeutose: capsule hairy. 



18. calycinuB, Willd. {ff. clirysdnthus, Hort.). Small 

 shrub from S. Africa, and sparingly known in this 

 country: pubescent: lvs. long-stalked, round-cordate, 

 somewhat 3-5-angled and 5-7-nerved, crenate, hairy or 

 velvety: fls. on axillary peduncles which are shorter 

 than the petioles, large, yellow, with a dark center: in- 

 volucre bracts 5, bristle-pointed: capsule tomentose. 



— To be grown indoors, but may be planted out in the 

 • with good results. Probably valuable for per- 



; planting in the extreme S. 



19. cispUtinuB, St. Hil. Bushy, 3-5 ft.: stems gla- 

 brous but prickly: lvs. deltciid-lauceolate or dt'ltoid- 

 ovate, 3-lobed, coarsely toothed, sparsely hairy on the 

 veins: fls. solitary, 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 the specific 

 name). R.H. 1898:480. Gng. 7:.50. — Little known in this 

 country. It is a 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. 

 Handsome. 



20. DSnisoni, Burb. Small glasshouse shrub, flower- 

 ing when very small, glabrous: lvs. thick and rather 

 stiff, slender-stalked, elliptic-ovate, entire or obscurely 

 crenulate, acuminate, dull green: fls. terminal, large, 

 white, 4-5 in. across. Nativity unknown, but int. from 

 Austral. P.M. 1876:2.32. — A good greenhouse plant, re- 

 quiring warm temperature. 



21. Edsa- Sinensis, Linn. (B. Sinensis, Hort.). Chi- 

 nese Hibiscus. Shoeblack Plant. Pig. 1058. In glass- 

 houses a shrub 3-8 ft. high, but reaching 20 ft. in sub- 

 tropical regions, glabrous: lvs. rather large, thin and 

 shining green, broad-ovate to lance-ovate, somewhat 

 tapering to the base, acuminate, coarsely and unequally 

 toothed: involucre bracts linear, free, as long as che 

 calyx tube: fls. solitary in the upper axils of the new

growth, on peduncles which exceed the petioles, bright 

 rose-red, 4-5 in. across, with a projecting red column of 

 stamens and pistil. Asia, probably China: now dis- 

 tributed in warm countries, and one of the best known 

 old-fashioned conservatory pot-plants. B.M. 158. I.H. 

 29:441. G.C. III. 2:529. Gn. 53, p. 127.-It is now im- 

 mensely variable. Forms are double-fld., and others are 

 orange, yellow, bright red, magenta, and parti-colored. 

 Var. Codperi, Hort. (H. Cnoperi, Hort.), has narrow 

 white-marked lvs. and distorted scarlet fls. Trade names 

 belonging to this species are H. brillidntissimus, H. 

 carniinAtus, H. chrysdnthus. H. fulgidus, M. fiiJgens, 

 H. kermeslnus, H. liiteiis, H. miniitus, S. sub-viold- 

 ceus, H. zebrXnus. Hibiscus Kosa-Sinensis is a sum- 

 mer-flowering shrub which always attracts attention. 

 It is often plunged in the open with other subtropical 

 stuff. It is easy to grow in ordinary potting soil. In 

 winter keep it slow by witholdiug water and keeping in 

 a temperature not above 50°. In spring head the plants 

 in and start them up to get the new wood on which the 

 flowers are borne. Give plenty of water when growing, 

 and syringe frequently. Prop, readily by softwood cut- 

 tings in spring, or by hard cuttings in fall.

HICKOKY-NUT. Notwithstanding the high esteem 

 in which the nuts of several species of Hickory have 

 been held since the settlement of America by the white 

 men, but little progress has been made in their domes- 

 tication and improvement. Out of the 9 or 10 species 

 recognized by botanists, not more than 3 or 4 have been 

 found sufficiently promising from an economic stand- 

 point to justify conspicuous effort at amelioration. Of 

 these the Pecan {H. Pecan) stands easily first, followed 

 in order of apparent value by the Shagbark (Little 

 Shellbark), fi^. oraM; the Shellbark (Big Shellbark), 

 U. lariiii.isii, and the Pignut, H. glabra. The Pecan 

 differs in its requirements of soil and climate from the 

 other species, and is . las, -lilied separately under P«can. 

 For the botany ,.i il,.- H Mk..rifs, see Bicoria. 



In flavor lunl .|iialiiy .d' kernel the Shagbark is 

 esteemed l>v iiai-i Aujrn, ans as the choicest of native 

 nuts, thou:;ii in ihr-a i, -la.-ts the ShnllliMrk is but lit-

the latter in in.,~t (ailtuiaii .-iraits; thuu-h the thriftv 

 growth, syrniuttiical foiiu and luxuriant f.iliage of the 

 latter render it one of the most handsome and useful of 

 native trees for roadside or lawn planting. The Shag- 

 bark has the broader area of natural distribution, being 

 found in localities throughout most of the United States 

 to the eastward of the Great Plains, except on the low- 

 lands of the South Atlantic coast and Gulf states. The 

 Shellbark is mainly confined to the vailey of the Mis- 

 sissippi and its larger tributaries, extending eastward, 

 however, into eastern Pennsylvania and western New 

 York. 



The Pignut, which is similar to the Shagbark in area 

 of distribution, is much inferior to the others in quality, 

 but shows wider variation than either in this respect, 

 and has disclosed at least one variety of distinct cul- 

 tural merit. 



As the Hickories, other than the Pecan, are slow-
