Cult. The greater part of the species of Malcomia being 
hardy annuals, they only require to be sown in the open ground, 
and if sown at various times throughout the summer and autumn, 
a succession of flowering plants may be kept up, until the frost 
kills them. Malcdmia Chia, maritima, incrassdta, and are- 
naria, are the most elegant of the annual kinds ; the other annual 
kinds possess no beauty, and therefore are only fit to be pre- 
served in botanic gardens. The perennial species, Malcomia, 
alyssoides, and patula, can only be increased by seeds ; they are 
very well adapted for ornamenting rock-work, All the species 
of this genus thrive best in a light dry sandy soil.

dicels filiform, never thickening after flowering. Flowers white
