HEMITELIA 



HERACLEUM 



bi-tripiimate, 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. Lvs. pinnate, the pinnse distant and 

 shghtly stalked, 6-12 in. long, 1-1}4 hi. broad, the base 

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

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

HEMLOCK in Old World hterature is what is 

 known as poison hemlock, an umbeUiferous herb, Con- 

 ium maculalum. By hemlock, Americans mean hem- 

 lock spruce, an evergreen tree, Tsuga canadensis. 



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

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

 rigida var. Sisalana. 



HEN-AND-CmCKENS. A proUferous form of the 

 English daisy, Bdlis pcrennis; 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-Leaf. Mayflower 

 (incorrectly). Stemlesg 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 lvs. 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 pecuhar fohage 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 accompUshed 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 httle is gained by this 

 as the flowers will not show until the next season. 



tnloba, Choix (Hepatica 

 Hepdlica, Karsten. Ane- 

 mbne Hepatica, Linn. A. 

 triloba, Hort.). Scapes 4r-6 

 in.: lobes of lvs. obtuse: fls. 

 H-1 in. across; sepals oval 

 or oblong, obtuse. EarUest 

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

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

 (as H. amcricana). White-, 

 blue-, and pink-fld. forms 

 have been fixed in cult., 

 and are known as var. alba, 

 Hort.; var. caerillea 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. acida, Pursh. Ane- 

 mone acutiloba, Laws, H. 

 acuta, Brit.). Fig. 1809. 

 Much like H. triloba, but 



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

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

 achenes slightly stipitate. E. U. S. 



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

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

 lobes often serrate: involucre near the fl. toothed; 

 fls. large, blue, whitish or reddish. 



1808. Flower of Hepatica. 



(Natural size) 



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 PUny). Umbelliferx. 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 lvs.: fls. 

 in large umbels, white or purpUsh, 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 foh- 

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