Cult. C. tomentosum, grandiflorum, and Dahuricum, are the 

 only species of this genus worth cultivating as border flowers. 

 C. latifblium, C. alpinum, and C. glaciate, are well adapted for 

 rock-work, or to be grown in small pots, in a mixture of loam, 

 sand, and peat ; the rest are only worth preserving in general 

 collections. They only require the treatment of other hardy 

 plants. The perennial species are increased by dividing the 

 plants at the roots. The annual and biennial species by seeds, 

 which should be sown in the open ground in the spring. 



XXXV. BRACHYSTE'MMA (from /3pa X c, brachys, short,

 the petals. Styles 2, distinct. Capsules spherical, 1 -celled, 

 with 4 valves opening even to the base, 1 -seeded. A diffuse 

 branched, smoothish herb. Stems pentagonal, rather pilose at 

 the top. Leaves opposite, elliptical, oblong, mucronate, stalked, 

 with cartilaginous rather serrulated margins. Flowers panicu- 

 lately corymbose, terminal or axillary. Peduncles many-flower- 

 ed, and are as well as pedicels glandular, furnished with linear

XXXVI. CHERLE'RIA (in honour of John Henry Cherler, 

 who assisted John Bauhin in his general history of plants.) Hall,

 densely-crowded leaves, and small solitary white or rose-coloured 

 flowers. Nos. 5 and 6 differ from the rest in the petals being 

 much longer than the sepals. Perhaps they belong to Arenaria.
