Order Lxxi
PORTULACEÆ.
With the exception of Turnéra, Támarix, Talínum, and a few species of Claytónia, the whole of this order consists of insignificant weedy plants, of no beauty, and little use. Claytónia perfoliáta and common purslane, which are occasionally used as salads, being the only species of a useful kind. They are chiefly herbaceous plants, frequenting dry barren situations, or the sea-shore of all parts of the world; all are insipid and inodorous, and destitute, as far as is known, of medicinal properties. Some of the kinds of Támarix have an astringent tonic bark, and yield, when burnt, a large proportion of sulphate of soda. Turnéra resembles a Cístus. 224 Móntia W. 537 Claytónia W. 689 Teléphium W. 1091 Portuláca W. 1092 Talínum Haw. 1093 Anacampséros L. 1036 Triánthema W. 871 Límeum W. 692 Portulacária W. 1037 Scleránthus W. 690 Corrigíola W. 686 Turnéra W. 685 Támarix W.
