 short-stalked, purple when young, but becoming beau- 

 tifully veined and blotched with white : fls. purple.

 outdoor use. Good for covering walls. Sometimes 

 grown in conservatories. A cross-section of the stem 

 presents a cross-form appearance, whence one of the 

 common names.

 fls. in liotb terminal and axillary panicles ; corolla gla- 

 brous, trumpet-shaped, 2H in. long, purple, with dark 

 rose stripes (but said in garden books to be yellow); 

 fls. sometimes only in 2's. W. Ind. and S. Amer. — Per- 

 haps not the plant known under this name in the trade. 



Chamberlaynii, Sims. Glabrous : leaflets ovate-acu- 

 min:itc', t;lal)iiais, shining above, paler beneath, more or 

 less tapering at base: fls. tubular, contracted below, 

 3—1 in. long, the limb comparatively short and spread- 

 ing, bright yellow ; cluster many-fld. Braz. B.M. 2148. 

 — Perhaps a form of the last. This species and B. 

 (pqiiioctialis are referred to the genus Anemopcpgma by 

 some.

 what angular, the young ones pubescent : leaflets usu- 

 ally 3, glabrous, ovate-acuminate, more or less tapering

BiUbergias can be cultivated best in greenhouses, 

 planted in pans, pots, wooden cribs, or wire baskets, 

 with loose, light material about their roots, such as 

 pieces of charcoal, roots of very fibrous plants, or fern 

 roots and sphagnum moss, and such material. They 

 require little water at the roots in winter, and nothing 

 but light sprinkling over the foliage is required to keep 

 them alive during that time. But in summer, when the 

 heat is great and they are making their growth, they
