BRYANTHUS 



BEYOPHYLLUJl 



of N. Eu. and N. Asia, in N. Amer. in the Rooky Mts. 

 southward to California. Heath-like prostrate shrubs, 

 quite hardy, with handsome, delicate fls., but rarely cul- 

 tivated. They thrive best in peaty and sandy soil, and 

 can only be grown, successfully in localities where the 

 air is moist and cool, but B. ereetus is less particular. 

 Prop, by seeds, sown in spring in peaty soil or cut 



monoecious, fascicled: fr. about the size of a cherry, 

 spherical, green, with pretty white markings. Asia, 

 Afr., Austral. F.S.12:1202.

 Has red fr. with white marks. I.H.12:431. F.S. 21:2237.

 and trained to rafters. Prop, by seeds. w. M.

ERYdNIA (Greek, to sprout, referring to the annual 

 growth from the tuber). Cucurbit&cece. A genus of 

 7 species of perennial cucurbits, natives of Europe and 

 W. Asia. They are herbaceous perennial climbers, with 

 the staminate fls. in racemes, while Bryonopsis is an 

 annual plant, with the staminate fls. in fascicles. All spe- 

 cies of Bryonia are dioecious except B. alia. Bryonopsis 

 is monoecious. See Cogniaux, in DC. Mon. Phan. 2:469. 



A. Fls . dicecious : stigmas rough : fruits red. 



di6ica, Jacq. Bryony. Height 6-12 ft. : root long, 

 fleshy, branching, white, a finger's thickness: Ivs. ovate 

 or roundish in outline, 5-lobed, margin wavy-toothed, 

 rough with callous points, paler beneath : pistillate fls. 

 greenish white, corymbose, short-peduncled. Common 

 in Eng. and in central and S. Eu. Rarer in W. Asia and 

 N. Afr. Not sold in Amer., but a common sight along 

 English highways. It grows rapidly over hedges and 

 fences. 

 AA. Fls. Wkoncecious : stigmas smooth : fni its black. 



Alba, Linn. Height 6-12 ft. : roots thick, tuberculate, 

 yellowish outside, white within: Ivs. long-petioled : pis- 

 tillate fls. in long-pedunoled racemose corymbs. Eu., 

 Caucasus, Persia.

BEYONdPSIS (Greek, Bryony-like). Cuctirbltdceo!.

 Bryonia for generic differences.

 deeply 5-lobed, rough, light green above, paler beneath; 

 segments oblong-lanceolate, acuminate, serrate : fls.

BKYOPH'S'LLIJM (Greek, sprouting leaf). Crassu- 

 Idcece. A small genus of succulent plants in the same 

 order with stonecrops, houseleeks and Cotyledon. The 

 only species in cult, is a rapid-growing window-plant, 

 and, like the Begonias, a familiar example of plants that 

 are propagated by leaf -cuttings. It is hardly a decora- 

 tive plant, but is very odd and interesting. It is only 

 necessary to lay the leaves on moist sand or moss, and 

 at the indentations new plants will appear after a time 

 (see Pig. 274). It is even possible to pin leaves on the 

 wall, and without water new plants will come. Useful 

 in botanical demonstrations.
