322 DECANDFJA— PENTAGYNIA. Oxalis. 



Perennial. Julij, 



Rather smaller than the last. Leafy branches very numerous, erect, 

 crowded, obtuse, thickly clothed with upright, awl-shaped, 

 shortish, acute, very glaucous leaves, imbricated in o rows ; 

 spurred and unconnected at the base : those on the flowering 

 stems scattered, broader and more tumid, often red. The stem 

 also is mostly red, especially its lower recumbent part. Fl. ra- 

 ther corymbose than cymose. Cal. very glaucous, with a tinge 

 of red ; its segments short, rounded, obtuse. Petals bright yel- 

 low, as well as the stamens and pistils. All the parts oi'ihejiower 

 are liable to an increase of number, even in wild specimens. 



U.S. Forsterianiim, Welsh Rock Stonecrop. 



Leaves spurred at the base, those of the branches semicy- 

 lindrical, bluntish, pointed, spreading, in many rows. 

 Flowers cymose. Segments of the calyx elliptical, ob- 

 tuse.

 valley of Nant-phrancon. Dr. Richardson and Mr. Llivyd. 



Perennial. Jidij. 



Very distinct from <S'. riipestre, with which it has been confounded, 

 in the bright-green colour of its foliage, v/hich is even less glau- 

 cous than represented in Engl. Bot. ; but the short rosaceous 

 tufts of spreading leaves, which are blunt, with a small bristly 

 point, more essentially distinguish it. The Jlowers grow in a true 

 ci/me, all the primary stalks springing from one point. The calyx 

 in this and the last has more shallow, short, elliptical and obtuse 

 segments, than in either of the tv/o preceding. Each leaf of 

 S^ Forsterianum has a dark spot, or pore, at the back, just below 

 the point, as in the uncoloured separate figure of Engl. Bot. But 

 of this there are also traces, even in dried specimens of ^S'. rw- 

 peslre. Mr. Griffith and Mr. Forster are of opinion that the 

 present is the only one_, of these two species^ ever found in 

 Wales.
