H. 



HAB 



Habena'ria. Rein Orchis. From habena, a 

 rein or thoug; referring to the long, strap- 

 shaped spur. Nat. Ord. Orehidacece. 



A well-known and somewhat extensive 

 genus of terrestrial Orchids, pretty generally 

 distributed. Our native species have very 

 curiously-shaped flowers, which are generally 

 yellow, but sometimes purple, and occasion- 

 ally white. They grow well in moist, shady 

 situations. Several of the species are to be 

 found in marshy places on the south side of 

 Long Island. 



Habe'rlea. Named after Karl Haberle, Professor 

 of Botany at Pesth. Nat. Ord. Gesneracem, 



H. rhodopensis, the only species, is an 

 elegant little hardy herbaceous perennial, not 

 unlike a miniature Gloxinia. Flowers pale 

 lilac, drooping. Admirably adapted for pot 

 or cold-frame culture. Introduced from Rou- 

 melia in 1880. 



Habit. The general appearance of a plant ; its 

 manner of growth, without reference to details 

 of structure. 



Habitat. The situation in which a plant grows 

 in a wild state. 



Habra'nthus. From /laftros, delicate, andanthos, 

 a flower. Nat. Ord. Amaryllidacece. 



Very handsome South American bulbs, 

 which like the rest of the order, should have 

 a decided season of rest. They grow best in 

 a rich soil composed of loam, rotted manure, 

 and sand, should be well-drained and have 

 plenty of water when growing or flowering. 

 These plants are found growing in dry, grav- 

 elly places, and are half hardy. They will win- 

 ter in a cold frame with slight protection ; in- 

 troduced in 1821. A number of the plants, 

 formerlj' included in this genus, are now 

 referred by the authors of the "Genera Plan- 

 tarum" to Hippeastrum and Zephyrantnes. 



Habrotha'ninus. From habros, gay, and tham- 

 no8, a shrub. Nat. Ord. Solana<:e(je. 



A genus of Mexican shrubs, closely allied to 

 Oestrum, and one of the gayest productions of 

 that country. The panicles of red or purple 

 flowers are borne in abundance, and justify 

 the name applied to them. They are propa- 

 gated by cuttings and were first introduced in 

 1814. Syn. Cestrum. 



Hackberry. See Celtis. 



Hackmatack. A local name for Larix Ameri- 

 cayia, the American or Black Larch. 



Hacque'tea. In honor of B. Hacquet, a German 

 botanist. Nat. Ord. UmbellifercB. 



H. Epipactis, the only species, is a hardy 

 herbaceous perennial plant, of very dwarf 

 habit, having digitate three-lobed leaves, and 

 a single umbel of small yellow flowers. It is 

 a native of the Alps, and, like most Alpine 

 plants, diffieult to manage here. Syn. Dondia. 



Haema'nthus. From haima, blood, and anthon, 

 a flower ; referring to the color of the spathe 

 and filaments of some species. Nat. Ord. 

 AmaryllidacetR. 



A genus of South American bulbous plants, 

 producing large scarlet, orange, and yeUow 



HAL 



flowers of very singular appearance. H. 

 coccinea, a beautiful species, does well in the 

 green-house and should be grown in sandy 

 loam and leaf mould. It is a strong grower, 

 requiring considerable room. After making 

 its growth it requires a season of perfect rest, 

 after which it throws up its flower stalk, and 

 should have plenty of water. They grow in 

 fall and winter, and rest during spring and 

 summer. They are propagated by offsets, and 

 were introduced in 1629. 



Heemato'xylon. Logwood. From haima, blood 

 and xylon, wood ; Logwood is well-known for 

 its red color. Nat. Ord. LeguminoscB. 



H. Campechianum, the well-known Log^vood 

 of commerce, is the only representative of this 

 genus. It is a handsome evergreen tree, grow- 

 ing about forty feet high, with a trunk about 

 a foot and a half in diameter. It was first 

 found on the Bay of Campeachy, in Yucatan, 

 whence its specific name. It is also found in 

 other parts of Central America, and has been 

 introduced into and become naturalized in 

 many of the West Indian Islands. Its impor- 

 tance consist in its value as a dye-wood, for 

 which purpose it forms an important article 

 of commerce. 



Haemodora'ceae. A natural order of perennial 

 herbs with fibrous roots, sword shaped equit- 

 ant leaves, and bearing wooly hairs or scurf 

 on their stems, and flowers. Natives of the 

 Cape of Good Hope, America and New Hol- 

 land. The roots of some of them yield a red 

 color, hence the name of the order. Anigosan- 

 thus, Alelris, Barbacenia and Hcemodorum, are 

 well known genera. 



Haemodo'rum. Blood-root. From haima, blood, 

 and doron, a gift ; probably in reference to the 

 roots serving as food for the natives of Aus- 

 tralia. Nat. Ord. HoBmodoracece. 



A genus of pretty green-house perennials, 

 all natives of Australia, with fascicled tubers, 

 and black, red, livid-green, or orange-colored 

 fiowers. Increased by division ; first intro- 

 duced in 1810. 



HairbeU. See Campanula. 



Hair Grass. See Aira. 



Ha'kea. Named after Baron Hake, a German 

 patron of botany. Nat. Ord. ProteacecB. 



A genus of green-house evergreen shrubs, 

 containing more than a hundred species, all 

 natives of New Holland. The flowers of 

 nearly all are white, produced in axillary 

 clusters. None of the species has sufficient 

 beauty, either in flower or foliage, to give it a 

 place in ordinary collections. 



Hale'sia. Silver Bell, or Snowdrop Tree. Named 

 after Dr. Hales, author of "Vegetable Statics." 

 Nat. Ord. Styracaceoe. 



A small genus of hardy deciduous shrubs or 

 low-growing trees. One of the species, H. 

 tetraptera, is found on the banks of the Ohio, 

 from Virginia westward, usually in very poor, 

 rocky soil. It is a free flowering shrub, or 

 small tree with beautiful pure white, showy, 

 drooping fiowers, on long slender pedicels, 

 much resembling the Snow-drop, whence its
