CRASSULACE.^. 12/ 



grows only a few inches high. Like the last, it has prostrate 

 barren shoots clothed with opposite wedge-shaped leaves, flat 

 and toothed. The flowers are in corymbs, are dull white, and 

 appear in summer and autumn. Native of the Caucasus. A 

 useful border species. 



S. populifolium (Foplar-kai'cd Stonccrop). — This is one of 

 the most distinct, though not the most beautiful, of the group. 

 It assumes rather a shrubby habit, about i foot high. The 

 leaves are flat, heart-shaped, toothed, and supported on stalks 

 that are lengthy for a Sedum. The flowers are in terminal 

 corymbs, and dull white, with purplish carpels and pistils. 

 Flowers in July and August. Native of Siberia. 



S. Rhodiola, syn. Rhodiola rosea (Roseroot Stonecrop). — This 

 is a well-known old-fashioned border-plant, common in many 

 cottage gardens in the country. It is not highly ornamental, 

 but has a good deal of distinctiveness about it. The stems 

 are leafy, stout, and erect, about i foot high. The leaves are 

 oblong, toothed, and slightly glaucous. The flowers are in 

 temiinal close corymbs, and each flower contains only one sex, 

 either male or female; and in colour they are in different indi- 

 viduals either yellow or purplish, the former in nature being 

 the most prevalent. Native of the mountains of Britain and 

 the mountainous countries of Europe and Asia. 



S. nipestre [Rock Sto7iecrop). — This is a dwarf creeping 

 species, forming lowly masses of barren stems, and branches 

 clothed with awl-shaped cylindrical leaves, more or less glau- 

 cous in hue. The flowers are in terminal cymes, composed of 

 several recurved branches, and bright yellow, appearing in July 

 and August. Native of Britain and various countries of 

 Europe. Two slightly - differing varieties are circulated in 

 gardens as species under the names reflexwji and Fojstei-i- 

 anum, but they are not desirable in any good collection to- 

 gether. 



S. sempervivoides {H ousel eek-Uke Stonecrop). — This species 

 differs from all the preceding. The leaves are thick and suc- 

 culent, egg-shaped, with an abrupt sharp point, and somewhat 

 hairy above and below, and arranged in close compressed 

 rosettes. The flowers, in terminal corymbs on erect stems, 

 are dark purple, appearing in July and August. Height from 

 9 inches to i foot. Native of Iberia. 



S. sexangulare {Six-angled Stonecrop). — This is near in aspect 

 to S. acre, but is quite distinct. It has the same close mat- 

 like growth, but the leaves are longer, narrower, and darker 

 green. The flowers are bright yellow, in the manner of those 

 of acre^ but begin to open as the latter become exhausted, and
