GENUS VIII. 
DRABA, Lin. THE WHITLOW GRASS. 
Lin. St/St. TETRADYNAMIA SILICULOSA. 
Generic Character— Silicic sessile, oral or oblong, with flat or convex valves. Seeds many, not margined. Calyx equal at the base. 
Petals entire. Stamens all toothless. ( G. Don. ) 
Description, &c. — Most of the species are little tufted evergreen plants, the leaves of which are generally 
ovate, and the flowers in terminal racemes. The flowers are white, or yellow. Generally only one species is 
cultivated in gardens ; though the British kind, D. aizoideg, has a very pretty effect in a tuft. D. pyrenaica, 
which looks like a miniature house-leek, and the flowers of which are either rose-coloured, or white tinged with 
pink, is now placed in a new genus called Petrocallis.
