Cult. Arenaria is a genus of dwarf herbaceous plants, for 
the most part perennial, the most of which are well adapted for 
ornamenting rock-work, but some of the rarer species should be 
grown in small pots well drained with potsherds, in a mixture of 
sand, loam, and peat, and placed among other alpine plants. 
Those species marked frame only require to be sheltered during 
frost. ‘The perennial species may be either increased by divid- 
ing the plants at the root, by seeds, or cuttings planted under a 
hand-glass will root freely. The annual kinds are not so shewy 
as the perennials, therefore they are not worth cultivating, except 
in botanical gardens ; they may be either sown on the rock-work 
or in the annual arrangement.

what globose. Styles 3. Capsule sessile, inflated, depressedly- 
globose, furrowed, imperfectly 3-celled, 3-valved, with the
