RtCCIA (P. F. Rieci, Italian nobleman, patron of the 

 botanist Micheli). Miccidceig. Riccia flititans, Linn., 

 is one of the few flowerless or cryptogamous plants in 

 cultivation aside from the ferns, mushrooms and se- 

 laginellas. It is cultivated by one specialist in aquatics 

 presumably for the benefit of students of botany. It is 

 not generally advertised among aquarium plants. In 

 this family of plants the plant-body is a thallus (i. e., a 

 green, flattish body not differentiated into root, stem 

 and leaves). The thallus of Riccia spreads out in green 

 patches which are at first radiately divided, and the 

 center of the plant often decays quickly. B. fluilans is 

 distinguished from other species by the linear, dichot- 

 oraous, floating thallus, with the capsule protuberant 

 from the lower surface. For full description, see Gray's 

 Manual.

BICHAEDIA (L. C. Richard, 1754-1821, French 

 botanist). ArAcece. Calla Lily. Perennial herbs 

 with many long-petioled leaves from a thick rhizome: 

 peduncles appearing with the leaves: petioles spongy, 

 often bristly below ; blade sagittate or lanceolate, 

 the numerous primary and secondary nerves ex- 

 current: peduncle as long or longer than the leaves; 

 spathe large, open, with a flaring, pointed, recurved 

 tip: spadix staminate above and pistillate below (Fig. 

 2127). Diffe-s from Peltandra in floral characters. So. 

 Africa. Species 10-12. See Gn. 46:446: R.B. 23:13. 

 Engler, DC. Monogr. Phaner, vol. 2. The true Calla 

 is not of this genus; see Calla. For the Black Calla, 

 see Arum. 



When grown for the flowers only, Ricbardias may be 

 planted out permanently on a bench, using very rich 

 soil and giving an abundance of water while growing. 

 They may be kept growing continually or given a sea- 

 son of rest as desired. Plants in pots are usually 

 started late in summer from dry tubers. The species 

 having yellow and pink spathes seem to do best when 

 grown without a resting period. 



A. Jjeaves lanceolate. 

 B^hmannl, Engler. Pink or Rose Calla. Dwarf 

 perennial: Ivs. lanceolate: spathes about 4 in. long, 

 erect, trumpet-shaped, with a caudate tip 1 inch long. 

 B.M. 7436. -In Natal the spathes are said to be dull 

 rose without, rose-purple within, with a dark crimson 

 blotch at the base inside. In cultivation the spathes are 

 white, with a faint rose tinge to the back and margins.
