plants are covered with large yellow fls. until hard 

 frost. The plants have bushy habit and beautiful, 

 feathery, glaucous foliage; 2 ft. The fls. at times stand

HUNTLEYA (personal name). Orchiddcese. Epiphy- 

 tal orchids without pseudobulbs, like Zygopetalum. 



Leaves several: fls. solitary on long peduncles in the 

 If .-axils ; sepals and petals similar, spreading, the lateral 

 sepals forming a slight chin; hp articulated to the foot 

 of the column, the upper part ovate, concave, narrowed 

 into a broad claw below with a fringed callus; column 

 broadly winged at apex; pollinia 4, upon an ovate 

 stalk. — Species 2, in Trop. Amer.

 exceeding the peduncles: fls. about 3 in. across; sepals

 white, the middle portion yellow, the upper part red-

HURA (South American name). Euphorbiacex. 

 Trees, cultivated in the tropics and sometimes in 

 greenhouses as curious or ornamental plants. 



Leaves simple, alternate, broad, petioled, hairy: fls. 

 monoecious, apetalous; staminate calyx cupulate, 

 truncate or denticulate; stamens generally numerous, 

 in 2-3 whorls; style long, with flat, radiate stigma; 

 ovules 1 to each of the 5-20 cells: fr. large, flat. — Two 

 species of Trop. Amer. 



The sandbox tree, H. crepitans, is noted for its 

 explosive capsules which, when ripe, throw the seed 

 many feet with a loud noise. The large poplar-like 

 leaves on long petioles give it quite an ornamental 

 aspect, and it is often planted in the tropics of both 

 hemispheres. It may be grown in Florida and Califor- 

 nia. The abundant milky juice is poisonous. The tree 

 is suited to light loam soil and is propagated by cut- 

 tings in sand with heat, under glass. 



crepitans, Linn. Sandbox Tree. Monkey Dinner- 

 bell. Fig. 1923. A tree up to 100 ft. high: lvs. broad- 

 ovate, cordate, acuminate, distantly repand-dentate: 

 fls. small, reddish: caps. 3 in. wide, li,'2 in. thick, deeply 

 many-ribbed. Trop. Amer. Lyon Horticole, 1907:125.

HUTCHINSIA (named for Miss Hutchins, of Ire- 

 land, who was sldlled in cryptogamic botany). Syn. 

 Hymenolobus. Cruciferse. Low, annual or perennial 

 herbs with entire or pinnate lvs. : fls. white, small, sub- 

 corymbose; pedicels elongated: fr. long-oval or lance- 

 shaped; seeds many or only 2. — Eight species in the 

 Medit. region and the colder parts of the Old World, 

 one species being very widely spread. According to 

 some authorities, Hutchinsia is hmited to one species. 

 H. alpina, Ait., is a good subject for the alpine garden 

 and is also occasionally used as a border plant. It 

 grows from 1-4 in. high: lvs. pinnate, shining: fls. 

 .snow-white, in clusters, blooming from May to June 

 and often through the summer. Cult, in moist half- 

 shadv places and prop, by seeds or cuttings. Gn. 72, 

 pp. 31, 278. 



HYACINTH: Hyacinthus. Hyacinth Bean: Dolichos. Hyacinth, 

 Grape: Muscari. Hyacinth, Water: Eichhornia. 



HYACINTHUS (name from Greek mythology). Lilv- 

 acex. Hyacinth. Popular hardy spring-flowering 

 bulbs, producing flowers in shades of blue and red, also 

 white; also grown under glass for winter bloom. 



Bulbs tunicated: stemless, the lvs. all radical, linear 

 or strap-shaped, the scape simple: fls. in a simple 

 terminal raceme or spike, erect or spreading or pendu- 

 lous; perianth funnel-shaped to campanulate, nearly or 

 quite equally 6-lobed ; stamens 6, attached at the throat 

 or in the tube: caps, nearly globular, 3-grooved or 3- 

 lobed, dehiscent loeuhcidally; seeds rather few. — Of hya- 

 cinths there are something over 30 species, the greater 

 part S. .\frican. Others inhabit the Medit. region, and 

 from this source come the common garden kinds. From 

 related genera, Hyacinthus is distinguished by the fun- 

 nel-shaped or bell-shaped fl., the throat not constricted, 

 the lobes shorter than or at most not much exceeding the 

 tube, the 6 stamens attached to the tube or throat and 

 the filaments thread-like or dilated at the base. For 

 the general cultural requirements, see Bulbs. 

 ' orientalis, Linn. Common Hyacinth. Fig. 1926. 

 Lvs. 8-12 in. long, }^-lJ^ in. wide, thick and green: 

 scape 8-18 in. tall, stout, bearing an elongated and dense 

 raceme: perianth about 1 in. long, the tube usually 

 ventricose or swollen, the lobes oblong-spatulate, as

long as the tube, in many colors, often double in cult. 

 B.M. 937. B.R. 995. F.S.23:2.399-2400.— The hyacinth 

 has been cult, for some centuries, and it shared some of 

 the early popularity of the tulip in the Netherlands. 

 It is wild in Syria, Asia Minor, Greece and Dalmatia. 

 It is extensively grown in Holland for export to this 

 and other countries, and consequently is commonly 

 known as the Dutch hyacinth. The Roman hyacinth
