 whitish centre, the midrib and main 

 veins being red and surrounded 

 with a green network.

 ish, spotted with red and white.

The genus Caladium has been much 

 confused with other genera like 

 Alocasia, Colocasia, etc., to which 

 the reader is referred. For garden 

 varieties it is better to consult the 

 current catalogues of specialists. 



CALLA {hallos, beautiful). Nat. 

 Ord. Aroidese. — The only species of 

 the genus — C. palustris — is a pretty 

 little water plant found wild in parts 

 of Central and Northern Europe and 

 North America. It is popularly 

 known as the " Bog Arum." It grows 

 about 6 ins. high, and has smooth, 

 deep green, heart - shaped leaves 

 springing up above the water surface 

 from creeping root-stocks. The male 

 and female flowers on the same 

 spadix appear in May and June, and 

 are protected by a pure white spathe, 

 the outer surface of which is tinged 

 with yellow. (Bot. Mag. t. 1831.) 



This pretty little plant is natural- 

 ised in parts of Britain. It grows 

 freely on the sides of rivers, lakes, 

 ponds, etc., or in marshy places, and 

 is easily increased by division of the 

 root-stocks. 



Several other plants, popularly 

 known as "Oalla," belong to the 

 genus Richardia (which see). 



CALLIPHRUBIA {hallos, beauti- 

 ful ; phroura, prison ; in reference to 

 the beauty of the spathe enveloping 

 the flowers). Nat. Ord. Amaryllideae. 

 —A small genus closely related to 

 Eucharis, and containing only the two 

 species here mentioned. 



C. Hartwegiana. — A pretty bulbous 

 plant from the Andes of Bogota. 

 The ovoid bulbs, with brown mem- 

 branous tunics, are about an inch in 

 diameter, and produce stolons freely. 

 The bright green oblong-acute leaves 

 are about 4 to 5 ins. long, and about 

 2 ins. broad. The white funnel- 

 shaped flowers are borne in umbels 

 of sis to eight on slender peduncles 

 about a foot long, about May and 

 June. {Bot. Mag. t. 6259.) 



C. tenera. — A native of the Andes 

 of New Granada, with round bulbs 

 about I in. through. The white 

 flowers are smaller than those of B. 

 Hartwegiarwb, and are borne on shorter 

 peduncles. This species is not in 

 cultivation. 



OALLIPSYCHB {hallos, beautiful; 

 psyche, a butterfly). Nat. Ord. 

 Amaryllideae. — A genus closely 

 related to Eucharis and Eucrosia, 

 having only three species of bulbous 

 perennials, natives of the Andes of 

 Ecuador and Peru. The bulbs are 

 tunicated, and furnished with oblong- 

 stalked leaves which appear after the 

 blossoms. These are funnel-shaped, 

 with a short tube, and the stamens 

 are remarkable for the great length 

 of their filaments.
