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. Malcomia Cliia, maritima, incrassata, 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 pdtula, 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. 



LV. HE'SPERIS (from tairtpos, hesperos, the evening ; be- 



cause the flowers of most of the species are sweet-scented in the 

 evening.) Lin. gen. no. 817. D. C. syst. 2. p. 446. prod. 1. 

 p. 188. 



LIN. SYST. Tetradynamia, Siliquosa. Silique roundish <or 

 somewhat 4-sided (f. 46. p.). Stigmas 2, erect, connivent.

 trous (f. 46. p.). Stamens all toothless. Annual, biennial or 

 perennial herbs, with fibrous roots, and erect or diffuse stems. 

 Leaves ovate -lanceolate or oblong, toothed or lyrately-runcinate. 

 The plants are for the most part furnished with simple or 

 branched lymphatic hairs, and others are furnished, especially at 

 the top, with glandular hairs, and from thence as if it were bi- 

 tuminous or clammy. Racemes terminal, bractless, erect ; pe- 

 dicels' filiform, never thickening after flowering. Flowers white 

 or purplish, often party-coloured, usually sweet-scented, parti- 

 cularly towards evening.

 grossly toothed, smooth or pubescent, 2 or 4 inches long ; hairs
