HEATHWORTS. Lindley's name lor 

 the Ericacem. 



HEAUMIER. (Fr.) Cerasus vulgaris. 



HEBECLADT7S. A genus of Solanacece, 

 closely allied to Atropa. The name is given 

 in allusion to the downy branches of the 

 species. The corolla is funnel-shaped, 

 with a large tube, longer than the calyx, 

 the limb spreading, wavy, five-cleft, fre- 

 quently with small teeth intermediate be- 

 tween the lobes. The species are natives 

 of tropical America, and one of them, H. 

 biflorus, with yellow flowers, is cultivated 

 in our greenhouses. [M. T. M.] 



HEBECLINIUM. A South American 

 genus of Composite, closely allied to Eupa- 

 torium, differing chiefly in the elevated 

 and villous instead of flat and naked 

 receptacles on which the florets are seated. 

 -The species are herbaceous or somewhat 

 shrubby plants with opposite leaves, and 

 the twigs are terminated by corymbs of 

 numerous white, purple, or rose-coloured 

 flower-heads containing tubular florets 

 with protruding styles. One of the most 

 handsome is the Mexican H. ianiliinum, a 

 good-sized bush, having the stems and 

 branches clothed with rusty down, and the 

 numerous flower-heads disposed in co- 

 rymbs, and of a fine mauve colour. [A.A.B.] 

 HEBENSTREITIA. A genus of Sela- 

 giuacece, containing sixteen species, na- 

 tives of the Cape of Good Hope. They are 

 undershrubs with alternate or scattered 

 leaves, and membranaceous bracts sur- 

 rounding the flowers. The calyx is mono- 

 sepalous, and the corolla tubular at the 

 base, with a somewhat one-lipped limb ; 

 there are four exserted stamens ; and the 

 deflexed style passes through a Assure of 

 the corolla. [W. C] 



HECASTOPHYLLUM. The same as 



Ecastap h y Hum. 



HECUBJEA. A genus of Composite 

 peculiar to Mexico, and there represented 

 by a single species, H. scorzonerce/olia, a 

 smooth unbranched herb about a foot 

 high, furnished with a few alternate entire 

 lance-shaped leaves, and terminal solitary 

 long-stalked yellow-rayed flower-heads an 

 inch or more across. The ray florets are 

 strap-shaped and female, the strap deeply 

 divided into three or five parts; and the 

 disk florets are tubular, five-toothed, and 

 perfect. The relationship of the genus is 

 with the North American Helenium, from 

 which it differs in the achenes being de- 

 stitute of pappus. The analogy of the two 

 genera is curiously expressed in the names 

 they bear : Hecuba was the daughter of Di- 

 mas, king of Thrace, and Helcnus {Hele- 

 nium) was one of her sons. [A. A. B.] 



HEDAROMA. A name sometimes given 

 to some iuvolucrate species of Genetyllis. 



HEDEOMA. A genus of labiates al- 

 most confined to the American continent, 

 but found in various countries from Brazil 

 to Canada. They are annual or perennial 



herbs or dwarf shrubs, with small leaves 

 and whorls of flowers borne towards the 

 tops of the branches. The genus is prin- 

 cipally distinguished from its allies by 

 having only the two lower stamens fertile, 

 the two upper ones being either short and 

 sterile, or altogether wanting ; and by the 

 corolla being short and never of a scarlet 

 colour. H. pulegioides, the Penny-royal of 

 America, is an annual, with numerous 

 branches, small opposite egg-shaped leaves, 

 and small pale-blue flowers. It is found in 

 the United States from Carolina to Canada, 

 and is extensively used for medical pur- 

 poses, particularly in domestic practice, 

 large quantities of it being brought to the 

 markets for sale. An infusion or tea of it 

 is a popular remedy for colds and pains in 

 the legs. The whole plant has a strong 

 pungent but pleasant scent, and a mint- 

 like taste. [A. S.] 



HEDERACE^E. Another name for the 

 order Araliacem. 



HEDERA. A genus of Araliaeece, con- 

 sisting of evergreen climbing shrubs, with 

 simple exstipulate leaves, and an umbellate 

 inflorescence. The margin of the calyx is 

 elevated and five-toothed, the petals five, 

 not cohering at the apex, the stamens five, 

 the style single with five obscure stigmas, 

 and the berries five-celled. The common 

 Ivy, H. Helix, one of our wild plants, is the 

 badge of the Gordons. This well-known 

 evergreen climber, which mantles and ca- 

 nopies the picturesque ruin, adorns in 

 winter the bare trunks of deciduous timber 

 trees, clothes the hedge-row banks of our 

 rural lanes, is admitted to various uses in 

 the decoration of our gardens, and is made 

 by poets the emblem of friendship. Its 

 steins cling by means of little rootlets to 

 the walls or tree-trunks with which they 

 come in contact, throwing out right and 

 left their shining five-angled leaves, but 

 after they have reached the summit of the 

 object to which they cling, they branch 

 out into woody bushy heads with simple 

 leaves, bearing at the end of every twig a 

 little umbel of yellowish flowers succeeded 

 by dark-coloured berries. The plant is 

 liable to much variation, and many interest- 

 ing varieties are in cultivation. Many tro- 

 pical species once referred here now form 

 the genera Oreopanax, Dendropanax, Agal- 

 ina, Sciadophullum, &c. An ivy-clad ruin 

 is shown in Plate 20. [T. M.] 



HEDGEBELLS. Calystegia sepium. 



HEDGEBERRY Cerasus avium. 



HEDGEHOG. Medicago intertexta. 



HEDGEMAIDS. Glechoma hederacea. 



HEDWIGIA. A "West Indian tree, 

 abounding in resin. It forms a genus of 

 Amyridacew, among which it may be dis- 

 tinguished by its four-parted flowers, and 

 by its fruit, which is fleshy externally, 

 furrowed, with four one-seeded stones in 

 the interior. [M. T. M.]
