 S. glaucnm, An. Eng. Bot. No. 2477. 



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

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

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

 species I. 



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

 from Babbicombe, Devon. 



England. Perennial. Summer. 



The Mildenhall plant, which is the 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 G inches high, the leaves 

 \ to i inch long^the flowers \ inch across ; in other respects it agrees 

 with S. eu-reflexum. 



Glaucous Stone-crop. 



SPECIES X.— SEDUM RUPESTRE. Iluds. 

 Plates DXXXVI. 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, 

 short./ stalked, numerous, in a corymbose cyme, with several 

 usually forked sub - scorpioid branches, which arc spreading- 

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

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

 shaped, rather acute.
