THE OXALIS. 139 



but little water at this time, though they must never be 

 allowed to get perfectly dry. 



Their propagation is by seed for those sorts from 

 which it can be had, and by division of the root of the 

 perennial species, and offsets of the bulbous kinds. Sow 

 the seed on the surface of pans or pots filled with peat, 

 leaf-mould, and maiden soil, slightly covered, and set 

 in a mild heat, being a little shaded. 



The CExothera. — By seed sown in the spring, and 

 by cuttings during the summer. 0. macrocarpa, yellow, 

 and O. taraxacifolia, white. Both are procumbent 

 varieties. By cuttings of the young growth, inserted 

 in pots of peat and pulverised manure. 



The Hepatica. — This is a species of Anemone, and 

 may be treated in a similar manner. Each crown may 

 be planted singly in the early autumn, but instead of 

 frequently removing them, let them remain. Seed may 

 be obtained from foreign merchants. Sow it in the 

 spring in deep seed-pans, and set in a cold frame till 

 up, then transplant out. 



The Echevaria (Crassulacea*) . — These are a pretty 

 tribe of hardy dwarf plants. The natural order ( Cras- 

 sulacece) conveys no idea of what the flowers of this 

 genus are. As I have said before, the term means 

 thick-leaved, and no more. The flowers of the Eche- 

 varias are very beautiful, and the plants themselves are 

 handsome-growing, and admirably adapted for a very 

 small bed on dry places, or for edgings, rockwork, &c. 

 They may be had from seed sown in seed-pans well 

 drained and filled with peat, leaf-mould, and maiden 

 soil of equal parts, with some sand added. Make the 

 soil firm and even, then sow the seed on the surface, 

 and slightly cover it with fine soil, and set in a mild 

 heat ; use the dewpot when water is required. They 

 may be readily propagated by offsets in the autumn. 



The Sedum [Crassulacew). — Although similar in some 

 instances to the Echevaria, the flowers are quite dif- 

 ferent. The Sedums are a hardy genus, flourishing on 

 stone walls, rocks, &c, and are most useful, many of 

 them being even beautiful. The leaves of some of them
