HYDRASTIS (name of doubtful meaning). Banuncn- 

 lAcea. Two species of hardy herbaceous perennials, 

 one from Japan and one from N. Amer. Stem erect, 

 pubescent: Ivs. palmately 5-7-lobed, serrate: fls. green- 

 ish white, small, solitary; sepals 3, petal-like, falling 

 early; petals none; stamens many; carpels 2-ovuIed, in 

 fruit becoming aggregated berries. Requires moist 

 situations in good, rich loam and leaf-mold. Prop, by 

 division of the root, and by seed. 



Canadensis, Linn. Orange Root. Golden-seal. 

 Stem "t-IO in. long, from a thick, yellow rootstock: 

 basal Ivs. 5-8 in. broad; stem Ivs. 2, lower one petioled, 

 upper sessile and near the small flower: fr. in ovoid 

 head, the 8-12 fleshy carpels tipped with a short, curved 

 beak. April. Eastern U. S., in rich woods. B.M. 3019 

 (in flower); 3232 (in fruit). -Used in gardens for the 

 showy leaves and beautiful red fruit ; root used in 

 medicine. K. C. Davis.

1.1. hty ..t sharp sand and good drainage. The seeds and 

 seedlings should be treated more like the commercial 

 Areca, i.e., Chrysalidocarpiis tutescens. It forms a sin- 

 gle stem when only 3 ft. high, and grows to a height of 

 20 ft. or more in cult. It is at its best when 10 to 15 ft. 

 high. When well established and pot-bound it loves 

 high feeding, as does Cliryscilidocarpus lutescens. This 

 palm has a bright future commercially.

Morsus-rinae, Liim., has floating stems resembling run- 

 ners, and tufts of radical leaves, and submerged roots. 

 Lvs. stalked, roundish, with a heart-shaped base, rather 

 thick, about 2 in. across: peduncles of the staminate 

 plant bearing 2-3 fls. on long pedicels, which spring from 

 a spathe of 2 thiTi bracts: petals 3, white, stamens 3-12: 

 spathe of the pistillate fls. sessile among the lvs.: styles 

 6, with 2-cleft stigmas. For American Frogbit, see iim- 

 nobiiim. 



Hydrocharis dies in the fall, but winter buds (see 

 similar buds of Elodea, Pig. 759) break off and sink 

 when the old plants die. In spring, or in the green- 

 house or aquarium under genial conditions, they start 

 early into growth, the scales bursting and a young leaf de- 

 veloping and then the whole rises to the surface. It is a 

 very interesting plant. Its fine, silky roots are beauti- 

 ful and attractive in the aquarium, as well as the soft, 

 tender leaves and delicate flowers. '^jj, Tricker.

HYDKOCOTYLE (Greek, water and beaker; the 

 plants thrive in moistplaces, and the roundish lvs. have 

 a cup-like depression in the middle). Umbell'iferce.

 considerably used at Washington, D.C., for carpet bed-
