S. reflexum, /3 albescens, Bah. Man. Brit. Bot. ed. v. p. 130. 

 S. glaucum, Sm. Eng. Bot. No. 2477. 



Leaves glaucous, those on the flowering-stems not reflexed. 

 Flowers pale yellow. Want smaller in all its parts, and with the 

 leaves, especially on the barren shoots, more slender than in sub- 

 species I. 



Oq dry rough banks. Rare. About Mildenhall, Suffolk ; also 

 from Babbicombe, Devon. 



England. Perennial. Summer. 



The Mildenhall plant, which is tlie only one I have seen, I have 

 received from Dr. J. A. Power. This has the barren shoots short, 

 1 to 2 inches long, the flowering-stems 4 to 6 inches high, the leaves 

 -|- to -J inch long, the flowers \ inch across ; in other respects it agrees 

 with S. eu-reflexum. 



Glaucous Stone-crop. 



SPECIES X.— SEDUM RUPESTRE. Iluds. 

 Plates DXXXYI. DXXXVII. 



Stems laxly tufted, much-branched, producing numerous de- 

 cumbent barren shoots, rooting at the base and erect at the apex, 

 below the flowering-shoots. Leaves crowded, in about 14 very 

 irregularly-spiral longitudinal lines on the barren shoots at the 

 termination of which they form a rosette, more distant and spread- 

 ing or ascending on the flowering-stems, strap-shaped, flattened 

 above and beneath, acuminate or mucronate at the apex, pro- 

 duced at the base into a short obtuse or acute scale-like spur 

 applied to the stem. Plowers generally without bracts, yellow, 

 shortly stalked, numerous, in a corymbose cyme, with several 

 usually forked sub - scorpioid branches, which are spreading- 

 ascending when in flower, and connivent in fruit. Sepals oval, 

 rather blunt, not produced downwards at the base. Petals strap- 

 shaped, rather acute.
