106 CALYCIFLOR^ 



and very thick ; the flowers conspicuous for their star-like form, 

 their white petals spotted with red, and bright purple anthers. 

 Rocky and sandy places, especially near the sea. Fl. June, July. 

 Annual. 



4. 5. dasyphyllum (Thick-leaved Stonecrop). Very like the last ; 

 smaller, slightly viscid ; leaves mostly opposite, globular, and fleshy ; 

 flowers white, tinged pink. Old walls in the south ; an escape. 



5. 5. album (White Stonecrop). Rather taller than S. Anglicum 

 and more slender. Flowering-stems 4-6 inches high ; also barren, 

 prostrate stems ; leaves oblong, cylindrical, blunt, spreading, about 

 half an inch long ; cyme much branched, drooping when in bud. 

 Rocks and old walls. Supposed to be indigenous in the Malvern 

 Hills, and not uncommon as an escape. Fl. Jul}', August. Perennial. 



6. 5. villosum (Hairy Stonecrop). A small species, with hairy, 

 viscid stems and leaves and pinkish white flowers. Frequent in 

 Scotland and the north of England. Fl. June, July. Annual. 



7. S. acre (Biting Stonecrop). Leaves 

 egg-shaped, fleshy, spurred at the base, 

 sessile ; cymes 3-cleft. Very like S. Angli- 

 cum in habit, but with yellow flowers, and 

 growing in similar situations ; it may, how- 

 ever, be distinguished, when not in flower, 

 by its thicker and more crowded leaves, 

 which are very acrid, and have gained 

 for the plant the name of Wall-pepper. 

 Walls, rocks, and sandy ground ; frequent. 

 Fl. June, July. Perennial. 



8. S. sexangulare (Tasteless Stonecrop). 

 Sedum Acre Distinguished from the last by its longer 



(Biting Stonecrop) and more slender leaves, 6 in a whorl. Old 



walls. Found in the Isle of Sheppey and 

 elsewhere in the eastern counties, but not indigenous. Fl. July. 

 Perennial. 



9. S. rupestre (Rock Stonecrop). A species allied to S. reflexum, 

 with slightly flattened leaves, which are spurred below, and ter- 

 minal ; cymes of large yellow flowers. Found on St. Vincent's 

 Rocks and other limestone cliffs ; rare. Fl. June, July. Perennial. 



10. S. reflexum (Recurved Yellow Stonecrop). Leaves awl- 

 shaped, spurred at the base, nearly cylindrical, the lowermost 

 curved back. Easily distinguished from any of the preceding by 

 its slender but tough stems, 6-10 inches high, clothed with spreading 

 or reflexed leaves, which are cylindrical and pointed. Walls and 

 dry banks ; not uncommon, but probably not indigenous. Fl. July, 

 August. Perennial.
