HILLEBRANDIA 



HIPPEASTRUM 



HILLEBRANDIA, (Wm. Hillebrand, author of a 

 flora of Hawaii) . Begoniacese. One of the 4 genera of the 

 family, represented by a single Hawaiian species, H. 

 sandwicensis, Oliver. It is a begonia-like succulent herb 

 with alternate long-petioled obliquely cordate 5- to 9- 

 lobed Ivs. and bright pink or rose^colored showy fls. in 

 a peduncled corymb: from Begonia it differs in having 

 the ovary free in its upper third, and bearing petaloid 

 organs in the female fls.: petals 5 in both male and 

 female fls.; stamens many; styles 5, fleshy: caps, globose, 

 opening at apex, not winged. The plant grows 2-5 ft. 

 high, from a tuberous rhizome, sparsely hairy or gla- 

 brate. It inhabits deep ravines or near waterfalls in 

 different islands of the Hawaiian group. B.M. 6953. 

 G.C. III. 44 : suppl. Dec. 12. Requires the treatment of 

 shrubby or branching begonias, as in all regards but its 

 technical botanical characters it is a begonia.

HILLIA (Sir John Hill, 1716-1775, British botanist). 

 Rubiaceae. Shrubs of Trop. Amer., sometimes epiphytic, 

 2 of which are rarely grown as greenhouse or warmhouse 

 evergreen subjects. Smooth, branches often rooting: 

 Ivs. opposite, simple, more or less fleshy: fls. large and 

 rather showy, terminal and solitary, white and fra- 

 grant; corolla, salverform, the tube long; stamens 4-7, 

 inserted at the throat of the corolla: fr. a follicle. 

 Species about 10, W. Indies to S. Amer. H. tetrandra, 

 Swartz. Plant 3-4 ft., the root bearing tubers: Ivs. 

 obovate to lanceolate, cuneate at base and rounded 

 at top: lobes of corolla 4, roundish-oboyate, not more 

 than one-third length of tube. Mountains of Jamaica, 

 Cuba; June in cult. B.M. 7355. H. longifibra, Swartz, 

 has elliptical pointed Ivs., and 6-7 lanceolate bluntish 

 reflexed corolla-lobes. W. Indies; apparently not now 

 in the trade. L. H. B. 



HIMALAYA BERRY. The Himalaya berry is one 

 of the evergreen blackberries of Asiatic origin. It is 

 reported to have been introduced by Luther Burbank 

 in the early nineties, the seed being received by him 

 from an English traveler who secured it from the 

 Himalaya Mountains. The vine is heavily thorned 

 and a vigorous grower, making from 20 to 40 or 50 feet 

 in a season and continues to grow until cold weather. It 

 is of a trailing habit of growth, like the dewberry. The 

 fruit begins to ripen in midsummer and gradually 

 matures during a long period. As fruited in the Middle 

 West, the berries are medium or below medium in size, 

 decidedly tart unless dead ripe and with a more tender 

 core than is usually found in the blackberry. The 

 quality of the fruit is fair though not delicate in flavor. 

 The fruit is of firm texture and on the Pacific coast it 

 is reported as being a good shipper. 



The Himalaya berry, like ah 1 of the evergreen black- 

 berries, does not properly ripen its wood for winter and 

 is not sufficiently hardy to be adapted for planting in 

 the Upper Mississippi Valley and the other sections in 

 which the winters are severe. Where covered with a 

 heavy blanket of snow, the vines come through the 

 winter in fair condition but in open winters they are 

 completely killed back. 



The Himalaya berry has been widely planted in the 

 last three or four years, but it has not as yet established 

 itself as a commercial berry in competition with several 

 of the best standard varieties of blackberries with which 

 it would be compared. See Rubus. A. T. ERWIN. 



HIMANTOGL6SSUM: Orchis. 

 HlMANTOPHtLLUM: Imantoph V Uum=Clima. 



HIPPEASTRUM (knight or horse and star, from some 

 fancied resemblance in H. equestre, perhaps of the 

 equitant leaves and the star-shaped corolla-opening). 

 Amarylliddcese. Includes Habrdnthus. Showy bulbous 

 plants, blooming in late winter to early summer; 

 handled under glass in frosty climates. Some of them 



are frequently grown as spring- or summer-blooming 

 house-plants. 



Bulb tunicate: scape hollow: Ivs. linear or strap- 

 shaped: fls. large and showy, usually two to several 

 being borne on a stout, leafless scape; perianth-tube 

 evident, often long, dilated in the throat; segms. erect- 

 spreading, nearly or quite equal; filaments (6) distinct, 

 often with small scales between; throat of perianth often 

 closed or provided with scales or a corona: fr. a loculi- 

 cidally 3-valved caps.; seeds black, usually flattened 

 or compressed. From 60 to 70 Trop. American bul- 

 bous plants, much cult, and now much hybridized. 

 Closely allied genera are Amaryllis (African), Crinum, 

 Sprekelia, Brunsvigia, Zephyranthes, Lycoris, Stern- 

 bergia, Vallota. The genus divides itself into the nar- 

 row-lvd. (Ivs. linear) and broad-lvd. sections. All the 

 common garden sorts belong to the latter section. The 

 species chiefly known hi cult., or which have been 

 parents of hybrid races, are contrasted in this account, 

 although the kinds commonly seen are hybrids or 

 derivatives. In some species the fls. precede the Ivs. 



The hippeastrums are usually known in gardens 

 under the general name of amaryllis; and their culture 

 is given in full under that name. Many of them are 

 noble garden plants, but the high price of the bulbs 

 prevents them from becoming popular. Most of the 

 species were first described in the genus Amaryllis, but 

 that genus differs in its solid scape and absence of scales 

 between the filaments. Gardeners sometimes secure 

 blooming plants hi two years from seeds, by keeping the 

 plants growing nearly continuously. The seeds are sown 

 in flats and pricked off into small pots at the two-leaf 

 stage. By the close of summer, they are shifted into 4- 

 or 5-inch pots and grown through the winter. They go 

 into about 6-inch pots when one year old, where they 

 grow till the second winter, when they are then partially 

 rested; in late winter, they begin active growth again, 

 and can be brought into flower in spring. 



Very many of the names in trade catalogues are of 

 horticultural forms; and many of them cannot be 

 referred positively to any of the original species. For the 

 Belladonna lily, see Amaryllis; for Atamasco lily, see 

 Zephyranthes; for Josephine lily, see Brunsvigia. For 

 Amaryllis aurea, see Lycoris; for A. Candida, see 

 Zephyranthes; for A. formossissima, see Sprekelia; 

 for A. gigantea, see Brunsvigia; for A. longifolia, see 

 Crinum; for A. lutea, see Sternbergia; for A. Nerine, 

 see Nerine; for A. orientalis, see Brunsvigia (B. gigantea) ; 

 for A. ornata, see Crinum; for A. speciosa or purpurea, 

 see Vallota. Following are Latin-form trade names, 

 probably of hybrids: atrosanguineum, cardinalis, crocea, 

 delicata, formosa, Lindenii, macrantha, refulgens, rubis 

 (hybrid), rubra striata, Williamsii. Other trade names 

 may be expected in the lists of dealers.
