180 1)1 CANDUIA — PENTAGYNIA. [Oxulis. 



Walls, rocks, and saiuly ground, frequent, Fl. June. V-. — Distin- 

 guished among our yellow-Howered species, by its upright, short and 

 very succulent leaves, closely imbricated on the barren shoots. Very 

 biting when chewed; and hence its name of Wall pepper. 



7. S. sexanguldre, L. (tasteless yellow Stotiecrop) ; leaves gener- 

 ally in 6 rows whorled on the barren shoots cylindrical fleshy 

 spreading produced at the base, cymes trifid. E. Bot. t. 1946. 



Old walls in the east of England, rare. Isle of Sheppey; Greenwich 

 Park ; in Cambridgeshire, and Old Sarum. Fl. July. If.— Well distin- 

 guished from the last by its spreading, larger and slenderer leaves, and 

 by their insertion. 



8. S. reflexum, L. (crooked yellow Stonecrop) ; leaves awl- 

 shaped scattered spurred at the base, the lowermost recurved, 

 flowers cymose, segments of the calyx ovate. Sm. — E.Bot. t. 695. 



Walls, roofs of houses and thatched buildings, frequent. Fl. July. l/I. 

 — Sterile branches with thickly placed leaves, often reflexed. Flower- 

 ing-stems 6 — 8 inches high. Cyme large, yellow. Flowers numerous, 

 often with 6 petals and 12 stamens. Very similar to this are the three 

 following species. 



9. S. glaucum, Donn, (glaucous yellow Stonecrop) ; " leaves 

 glaucous awl-shaped scattered produced at the base, those of 

 the branches thread-shaped, flowers cymose, segments of the 

 calyx lancieolate." E, Bot. t. 2477. 



Rough hills near Mildenhall, Sutiolk. Sunday's-well and Glaskeen, 

 Ireland. Fl. July. Aug. If. — " Differs from the last in being of a more 

 glaucous hue, with much slenderer leaves, especially on the radical 

 shoots. The branches of the cyme are more uniforudy spreading and 

 the segments of the calyx are narrower and more pointed." Sm. ^ 



10. S. riipestre, L. (St Vincent's Rock Sto7iecrop) ; "leaves 

 glaucous produced at the base, those of the branches awl-shaped 

 erect in five close rows, flowers imperfectly cymose, segments 

 of the calyx elliptical obtuse." E. Bot. t. 170. 



St Vincent and Cheddar rocks, Somersetshire. Walls about Dar- 

 lington, Yorkshire. Fl. July. If. 



11. S. Forsteridnutn, Sm. ( Welsh Rock Stonecrop) ; " leaves 

 produced at the base, those of the branches semicylindrical 

 bluntish pointed spreading in many rows, flowers cymose, seg- 

 ments of the calyx elliptical obtuse." E. Bot. t. 1802. 



Rocks in Wales ; fall of Rhydoll, Cardiganshire. Hisvjle, valley of 

 Nant-phrancon. Litlle Ormeshead. Fl. June, July. — " Perhaps the 

 compact, hemisphaerical or round-topped cyme is the best mark by which 

 to distinguish this from S. reflexum." 3Ir W. Wilson. » 



16. OxALis. Liiin, Wood-sorrel. 



1. O. Acetosella, L. (common Wood-sorrel); leaves all radical 

 ternate, leaflets inversely heart-shaped hairy, scape single- 

 flowered, root scaly. E. Bot. t. 762. 



Woods and shady places, frequent ; also at a great elevation on the 

 mountains, among shady rocks. Fl. May, and on the Alps, till August.
