7. S, sexangulu'rCf Linn, (Fig. 757.) Tasteless yellow Stonecrop, 

 Stem procumbent at the base, and rooting; leaves round, linear, 

 obtuse, spurred at the base, sessile; cymes smooth, leafy; petals 

 lanceolate, acute, twice as long as the calyx segments.

Boot of slender branched fibres. Stem roundish, smooth, succu- 

 lent, branched, somewhat tufted, procumbent and rooting at the base, 

 from two to three inches high. Leaves of a cheerful grass green, 

 round, linear, with an obtuse point, sessile, with a short obtuse spur at 

 the base, those of the stem in alternate whorls of three or four together 

 on the branches, crowded in a somewhat imbricated manner. Inflo- 

 rescence a terminal cyme, mostly of three spreading branches, with a 

 solitary flower iu the axis of divarication. Flowers mostly less nume- 

 rous than in S. acrcj nearly sessile. Calyx of oblong obtuse segments, 

 half as long as the lanceolate acute petals, of a bright palish yellow 

 colour. Stamens with slender awl-shaped filaments, shorter than the 

 petals. Anthers small, of two cells. Styles with small obtuse stigmas. 

 Capsules pale, thin, membranous. 



Habitat. — Oldi walls in the eastern parts of England ; rare. Isle of 

 Sheppey ; Greenwich Park wall ; in Cambridgeshire ; and the walls of 

 Old Sarum, Wiltshire. 



Perennial ; flowering in July. 



This species has a great resemblance to the former, from which, 

 however, it is readily distinguished by its linear obtuse leaves, its less 

 spreading habit ; and the bitterness of the whole plant is, though 

 austere, far less pungent and acrid than those of <S. acre. The dis- 

 position of the leaves upon the stems and branches is not materially 

 difi"erent from those of S. acre. Their insertion in opposite whorls of 

 three or four, gives it the sexangular appearance, from which circum- 

 stance Linnseusgave it the name, by which it is distinguished ; but this 

 disposition of them is often even more remarkable in S. acre than in 

 this species. 



Though a rare plant in England it is common in various parts of 

 the Continent, and in many parts of Italy much more frequent, 

 especially on old walls, than *S\ acre. 



8. S. reflex*um, Linn. (Fig. 758.) Crooked Yellow Stonecrop. 

 Leaves linear, awl-shaped, acute, with a bristly point, sessile, with a 

 short spur at the base, fleshy, scattered, the lower ones reflexed ; cyme 

 smooth ; calyx segments acute, much shorter than the lanceolate 

 petals.

Root of branched spreading fibres. Stem round, smooth, from six 

 to twelve inches high, procumbent at the base, and more or less 

 branched and spreading, flowering stems erect, scattered over with
