DIPCADI (meaning uncertain). Zilidce<r. Tender 

 bulbous plants of minor importance, allied to Galtonia, 

 with radical, thickish, narrowly linear Ivs. and loose 

 racemes of odd-colored fls. on leafless scapes. About 20 

 species in southern Europe, tropical and south Africa 

 and India. During the winter, their resting time, the 

 bulbs should be kept dry. A compost of light, sandy 

 loam and leaf -mold has been recommended. Latest mon-

 Umbrella Leaf. An interesting hardy perennial herb 

 with thick, creeping, jointed, knotty rootstocks, send-

 like, radical leaf on a stout sfiil!-. i- :i fn;.;,.ring stem

terminal cyme of white fls. : m [ li ' . ; iis: petals 



and stamens 6: ovules 5 or G: IjMin - ^l"Liuse, few- 

 seeded. This is one of many gi-nera having only 2 spe- 

 cies, one of which is found in N. E. North America, the 

 other in Japan. There is awonderful similarity between 

 the floras of these 2 regions, and few areas have pro- 

 duced so many plants esteemed in cultivation.

DIPLADfiNIA (Greek, double gland, referring to the 

 glands of the ovary, which distinguish this genus 

 from Echites). Apocynhcece. A 

 charming genus of coolhouse twiners, 

 mostly from Brazil, with large, showy 

 more or less funnel-shaped fls. having 

 a remarkable range of color, rarely 

 white or dark red, but especiallv rich

 ^ 1 ^niiie species are naturally erect 

 I ushes, at least when young, and 

 many can be trained to the bush 

 form. The group is a most tempting 

 one to the hybridizer. An all-yellow- 

 flowered kind is desirable. Many names

 Although Dipladenias are natives of the tropics, they 

 grow at high altitudes, and it is a mistake to keep them 

 in close, steaming hothouses, as many gardeners do in 

 the Old World. The writer has kept them in a house 

 whose temperature was never above 50° P., and fre- 

 quently went down to 40° on winter niglits. Cuttings 

 should be rooted in winter, and the youiiL' I'laiito ,,];,„tr.ri

 fine specimen may be grown in a pan 2 ft. across and

 the nights get cooler, the water supply maybe gradually
