ACCOUNT OF GENUS SEDUM AS FOUND IN CULTIVATION. 179 
It was collected in Spain by F. Sundermann of Lindau (see his 
Catalogue for 1913), and distributed under the name S. nvulare ; but 
S. rivulare Boissier (= S. melanantherum DC.) is a different plant, 
resembling a slender 5. anglicum (for illustration see Boissier, " Voyage 
Midi d'Espagne," tab. 63). 
I have grown a large series of dasyphyllum forms, collected mainly 
from garden sources, and find them puzzHng. They vary much, in 
the first place, in size (from type to macrophyllum) ; next, in hairiness, 
from quite glabrous (sub-var. glabratum Rouy and Camus), sent by 
Dr. ScHROETER from Zurich, and collected on a wall at Midleton^Co.

Cork, to the densely hairy glanduliferum. Then one very hairy form 
has leaves which readily drop off, so that after heavy rain the stems 
are almost bare and the fallen leaves soon form a dense mat of young 
plants ; while in other hairy forms the leaves are firmly attached. 
According to Kerner, the flowers are sometimes replaced by 
leaf-buds.

Synonyms. — S.farinosum of gardens (not of Lowe, which is a Madeira plant 
allied to album, and not in cultivation so far as I am aware). 5. Pittoni (a nomen 
nudum) of gardens.

A delightful, tiny plant, known at once by its sub-globular mealy 
reddish leaves, arranged in four close vertical rows, and small white 
flowers.
