HEMITELIA 



HERACLEUM 



bi-tripinnate, the secondary rachis distinctly winged, 

 especially at the upper portion: sori few in each segm., 

 usually 2-4; indusium ciliate and often lobed. Var. 

 Paradae, Hort., is the form commonly in cult. British 

 Guiana. I.H. 24:280. 



Lindenii, Hook. Lys. pinnate, the pinnae distant and 

 slightly stalked, 6-12 in. long, 1-1 M m - broad, the base 

 truncate or wedge-shaped: sori in 2-3 irregular lines 

 near the margin. Venezuela. I.H. 42:46.

HEMLOCK in Old World literature is what is 

 known as poison hemlock, an umbelliferous herb, Con- 

 ium maculatum. By hemlock, Americans mean hem- 

 lock spruce, an evergreen tree, Tsuga canadensis, 



HEMP: common hemp is Cannabis sativa (which see); Bow- 

 string H., Sansevieria; Manilla H., Musa textilis; Sisal H., Agave 

 rigida var. Sisalana. 



HEN-AND-CHICKENS. A proliferous form of the 

 English daisy, Bellis perennis; also the thick-leaved 

 rosettes of Cotyledon, used in carpet-bedding, usually 

 as Echeveria. 



HENBANE: Hyoscyamus niger. 

 HENFREYA: Asystasia. 



HEPATICA (liver-like, from the shape of the leaves). 

 Ranunculdcese. HEPATICA. LIVER-LEAP. MAYFLOWER 

 (incorrectly). Stemless low perennials sometimes 

 grown in the wild border for very early spring bloom. 

 Leaves 3-lobed and sometimes toothed, appearing 

 after the fls. and remaining green over winter: scapes 

 1-fld., with an involucre of 3 small sessile Ivs. simu- 

 lating a calyx; sepals petal-like, white, pink or purple: 

 achenes short-beaked, pubescent. (Fig. 1808.) A 

 genus of 3 species, natives of the north temperate 

 zone, grown in open flower-beds for their attractive 

 fls., which appear in early spring; the peculiar foliage is 

 also much admired. 



The plants prefer shade, but do fairly well in open 

 places. They should remain undisturbed from year to 

 year, in rich well-drained loam. Well suited to the 

 north or east slope of a rockery. Plants kept in pots 

 in a coldframe until midwinter will quickly bloom at any 

 time desired if removed to a warm room or greenhouse. 

 Propagation of old plants is easily accomplished by 

 division of the roots. Seeds may be sown very shallow 

 in a moist, shaded soil. The seed is sometimes started 

 in frames in very early spring and the plants trans- 

 planted to the garden later, but little is gained by this 

 as the flowers will not show until the next season. 



triloba, Choix (Hepdtica 

 Hepdtica, Karsten. Ane- 

 mone Hepatica, Linn. A. 

 triloba, Hort.). Scapes 4-6 

 in.: lobes of Ivs. obtuse: fls. 

 J^j-1 in. across; sepals oval 

 or oblong, obtuse. Earliest 

 spring. E. U. S., Eu., and 

 Asia. B.M. 10. B.R. 387 

 (as H. americana). White-, 

 blue-, and pink-fld. forms 

 have been fixed in cult., 

 and are known as var. alba, 

 Hort.; var. caeriilea fl.-pl., 

 Hort.; var. riibra fl.-pl., 

 Hort. Gn. 26:24. Gn. M. 

 15:306. G.C. 1873, p. 645 

 (var. marmorata, Moore). 



acutfloba, DC. (H. triloba 

 var. acuta, Pursh. Ane- 

 mone acutiloba, Laws, H. 



1808. Flower of Hepatica. acuta, Brit.). Fig. 1809. 

 (Natural size) Much like H. triloba, but 



with the lobes of the Ivs. ovate and acute, occasion- 

 ally the lateral lobes 2-cleft (rarely the middle one): 

 achenes slightly stipitate. E. U. S. 



angulosa, DC. (Anemone angulosa, Lam.). Plant 

 tufted as in the other hepaticas, hairy: Ivs. 3-5-lobed, 

 lobes often serrate: involucre near the fl. toothed; 

 fls. large, blue, whitish or reddish. Hungary. B.M. 



1809. Hepatica acuti- 

 loba. The flowers of 

 hepatica droop and close 

 at night.

 G. 2:551. Var. alba, Hort. Fls. large, pure white, 

 var. rdsea, Hort. A rose-colored form. Var. lilacina, 

 Hort. A free-flowering variety with lilac-colored fls.

HEPTAPLEURUM: Schefflera. 



HERACLEUM (dedicated to Hercules, who used it in 

 medicine, according to Pliny). Umbelliferae. COW- 

 PARSNIP. Perennial or biennial herbs, some of which 

 are used in bold planting effects where there is ample 

 space. 



Mostly tall and coarse herbs, with prominent and 

 often very large lobed or pinnate or dissected Ivs.: fls. 

 in large umbels, white or purplish, with mostly obcor- 

 date petals and the outer ones often larger and cleft and 

 forming rays: fr. obovate, oval or orbicular, dorsally 

 flattened, the oil-tubes extending scarcely below the 

 middle. Probably 70 species, in the northern hemis- 

 phere, one reaching Abyssinia. 



Heracleums are not suited for general gardening, but 

 are sometimes grown in wild gardens or parks, or as 

 single specimens on lawns, where a very bold and 

 striking object is desired. The garden species are 

 coarse herbs, growing 5 to 10 feet high, with broad foli- 

 age, which is their chief beauty. They are adapted to
