1242. Cborozemas are subject to attacks of red-spider and mildew. The 

 best remedy is sulpliur-and-water vigorously and plentifully supplied. Take 

 a plant and lay it on its side in the open air, then with the syringe wash it 

 thoroughly : after watering, dust it with sulphxir, and repeat the dressing until 

 the pest is destroyed. 



1243. The following are some of the most distinct and beautiful of the series 

 ■which are met with in cultivation : — 



C. anpustifolia, — a remarkably graceful 



shrub, with long, slender, and some- 

 what scrambling stems, having linear 



acute leaves with recurved margins, and 



racemes of pretty flowers, of which the

April. New Holland. Introduced 1830 : 



formerly called Dillwynia glyeinefolia . 

 C. cordata,— an elegant dwarf shrub, with 



many slender branches, clothed with 



sessiii-cordate, obtuse, spiny -toothed 



leaves, and bearing the flowers in more 



or less drooping racemes. They are 



orange in the standard, with scarlet or 



crimson wings, sometimes scarlet with 



purple. Flowers in March and April.

 growing shrub, furnished with narrow 



leaves, and bearing a profusion of

short twiggy branches, covered with

1244. Shade regularly in bright weather, placing such plants that bear a 

 pretty free exposm-e to the sun's rays in the lightest part of the house. Make 

 it a rule to examine plants in baskets, &c., that the necessary dampness of the 

 growing material may be uniform, for nothing tends more to check the growth of 

 orchids than want of attention to this in the growing season. Pharus, zygo- 

 petalums, cyrtopodiums, and other terrestrial genera, will be benefitted by 

 being plunged in bottom-heat during the season of active growth. 



1245. About the second week, conservatory and stove climbers will require 

 attention to keep the current year's shoots within proper limits. Avoid any-
