 a recent introduction, has shorter flowers and a different 

 calyx, otherwise it generally resembles B. grandiflora. The 

 plants are all the better for an annual pruning on short- 

 spur lines. 



BERBERIDOPSIS 



A monotypic genus related to the Barberry. B. cor- 

 allina, a native of Chili, with spiny-margined leaves, and

 in addition, it is worthy of a place in the cool greenhouse. 

 It is propagated from seeds, sown in spring, by layering in 

 autumn, or by cuttings of new wood. 



BIGNONIA 



A large genus of handsome American, free-growing, 

 usually scandent shrubs, some of which have tendrils. B.

 is the hardiest, and may be grown on a south wall. It has 

 orange-brown tubular flowers produced in summer, and 

 slender shoots, as much as 20 feet in length. Those that 

 are grown under glass are only suitable for large houses ; 

 they should be planted out, and trained up the back wall of 

 a lean-to structure, or on trellis wires near the glass. 

 Thinning the shoots so as to assist ripening of the wood

 B. magnificat, B. regalis, B. speciqsa, and B. venusta are 

 favourites for stove cultivation. A compost of two parts
