The moss-like covering of the "bedeguars" of the wild rose, the galls of a Cynipid, Rhodites rosae, represents leaves which have been developed with scarcely any parenchyma between their fibro-vascular bundles; and the " artichoke-galls " or " oak-strobile," produced by Aphilothrix L., which insect arrests the development of the acorn, consists of a cupule to which more or less modified leaf-scales are attached, with a peduncular, oviform, inner ga11.4 E.
Thus the Jerusalem artichoke, though able to produce stems and tubers abundantly, only flowers in exceptionally hot seasons.
The more important are treated under their individual headings (see Artichoke, Asparagus, Bean, &c. &c.).
Protect endive, celery, artichoke and sea-kale with stable-litter or fern, or by planting the former in frames; take up late cauliflower, early broccoli and lettuces, and place them in sheltered pits or lay them in an open shed; earth up celery; manure and dress up asparagus beds.
2 Of ordinary table vegetables a considerable quantity and variety are grown: such are the cabbage, cauliflower, solanum (egg-plant), cucumber, hibiscus (bamieh), lettuce, carrot, artichoke, &c. The potato is also grown in considerable quantities.
The Berber diet largely consists of cucumbers, gourds, water-melons and onions, and a small artichoke (Cynara humilis) which grows wild.
Among the nine hundred species of Solanum less than a dozen have this property of forming tubers, but similar growths are formed at the ends of the shoots of the common bramble, of Convolvulus sepium, of Helianthus tuberoses, the so-called Jerusalem artichoke, of Sagittaria, and other plants.
