Native of Mexico, near Real de Moran. The colour of the flowers 

 is unknown, but the plant is said to be very like S. A'nglicum, 

 and the flowers are therefore perhaps white.

 181.) stem erectish, puberulous ; leaves nearly terete, glaucous, 

 alternate ; sterile branches crowded, erect ; cymes trifid, few-

 on sandy hills. Willd. enum. p. 486. S. Hungaricum, Poir. 

 S. Andersonii, G. Don in Loud. hort. brit. p. 184. According 

 to Willd. this species differs from S. sexfidum in the stem being 

 a little branched at the base, in the petals being 1 -nerved, not 

 finely 3-nerved. Flowers sometimes hexandrous.

 nicled ; flowers sessile along the branches ; petals 6, acuminated.

 Flowers white ; anthers bay-coloured. The flowers contain also 

 1 2 stamens, and are allied to S, rubens. The petals are said to be 

 3-nerved, the lateral nerves very fine.

49 S. ANDEGAVE'NSE (D. C. prod. 3. p. 406.) stem erect, 

 simple at the base, trichotomous at the apex ; leaves ovate, ob- 

 tuse, erect, fleshy, glabrous : lower leaves opposite, the rest 

 alternate ; flowers pentandrous in the forks, and scattered and 

 sessile along the branches ; petals ovate, acutish. O- H. Na- 

 tive of Andegavany, on walls and on schistous rocks. S. atra- 

 tum, Bast. ess. fl. p. 167. exclusive of the synonyme. Crassula. 

 Andegavensis, D. C. suppl. fl. fr. p. 522. Truly distinct from 



S. atratum, but perhaps only a pentandrous variety of S. dasy- 

 phyllum, and the flowers are probably white like it.

 rarely alternate ; sterile branches rather imbricated ; cymes pu- 

 berulous, few-flowered, terminal ; petals bluntish. If.. H. Na- 

 tive of Europe, on walls and rocks. In England plentiful about 

 London, as at Hammersmith, Kew,Chelsea, &c. ; on walls at Mai-
