ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 30I 



Var. minus, var. nov.* (fig. 178, b). 



Perennial. Smaller in all its parts, with many crowded barren 

 shoots densely clothed with glaucous leaves J inch long, flowering 

 stems about 2 inches high, floral parts in sixes, carpels hairy. 



This is the small, glaucous form long used for carpet-bedding under 

 the name of 5. glaucum or 5. Lydium glaucum. The latter name, 

 though erroneous, is apt, as out of flower the plant much resembles 

 a glaucous S. Lydium. Quite perennial. There is a form of it with 

 yellowish foUage, known in gardens as S. Lydium aureum. Though 

 long in cultivation and most distinct, this plant appears to be 

 undescribed. I have no information as to its native habitat. 



Regarding the " S. Wightmannianum, or 5. Whitmanni oi ^2sd&ns," 

 of which an incomplete description is given by Masters [Gard. Chron. 

 1878, ii. 751), I have no information ; the names do not appear to be 

 found in gardens now. His " 5. Witmanni of some gardens " (p. 685) 

 refers to S. hispanicum ; and as in the index to his paper Witmanni 

 is corrected to Whitmanni, the presumption is that all three names 

 represent that species. 



Not infrequent in gardens, mostly as S. glaucum. The oldest 

 name, hispanicum, is not an appropriate one, as the plant does not 

 occur in Spain, though originally believed to do so.

A small downy biennial, with fleshy, linear-oblong leaves and 

 small pink flowers, and stems usually much branched near the base. 



Description. — Biennial, downy. Stem erect, red, downy, leafy, 2 to 6 inches 

 high, usually emitting ascending branches below, some of which flower. Leaves 

 alternate, linear-oblong, blunt, downy, sessile, not spurred, fleshy, flat above, 

 rounded below, J to ^ inch long. Inflorescence a lax. corymbose cyme with erect 

 branches. Buds ovate, blunt. Flowers \ inch across, shorter than the pedicels. 

 Sepals very fleshy, lanceolate, blunt, hairy. Petals pale purple, ovate, apiculate, 

 twice the sepals, with a hairy back and often a purple keel, concave longitudinally 

 and transversely. Stamens shorter than the petals, filaments white, anthers dull 

 purple. Scales small, yellowish, emarginate. Carpels bright green, oblong, erect, 

 shorter than the stamens ; styles short. 



Flowers June-July. Hardy. 



Habitat. — From Greenland and Iceland across Europe to Serbia 

 and Algeria. Frequent on damp roadsides in many districts in 

 Scotland and N. England. 



A little biennial plant of no horticultural interest, and seldom 

 seen in gardens. It is very exceptional among Sedums in inhabiting
