Woolly Bean-caper. Pl. ? 
Cult. Zygophyllum is a genus of herbaceous plants and shrubs, 
bearing very pretty flowers. The greenhouse, stove, and frame 
species will thrive in a mixture of loam, peat, and sand ; and 
cuttings of the perennial and shrubby kinds will root freely 
in a pot of sand under a hand-glass, but as a few of them 
ripen their seeds this will be unnecessary. The annual species 
should be sown in pots in the same kind of soil, and placed in a 
hot-bed, where they may remain until they have seeded, or they 
may be removed to the greenhouse. Z. Fabago is the only 
hardy herbaceous kind ; it will grow well in any light soil, in a 
dry situation, otherwise it is apt to rot; it is only to be increased 
by seeds, which sometimes ripen in this country; these require 
to be sown in a pot, and placed in a frame, and when the plants 
are about 4 inches high, they may be planted out in the open 
border in a warm, dry, sheltered situation,
