180 ALPINE PLANTS 
generally glaucous. Flowers large, singly or few on a 
short stem. Whiteor yellow. Well-drained gritty soil suits 
best in fairly dry positions. Examples: S. apiculata, 
S. burseriana, etc. 
Miscopetalum.—Foliage round, undivided, stalked. Pani- 
cled flower stems bespangled with white or spotted flowers. 
Prefer light sandy soil, and shady positions. Example: 
S. rotundifolia. 
Nephrophyllum.—Of tufted growth, with stalked leaves 
from base, and erect flower stalks branching into panicles 
of white- and sometimes yellow-tinted flowers. Require 
moist fibrous soil, some shade. Example: S. granulata. 
Peltiphyllum.—F lower spikes strong and carrying round 
heads of pink, or sometimes white flowers which appear 
before the leaves. Foliage broad-spreading on top of sub- 
stantial stalks, umbrella-like in form. Suited for stream- 
side planting or among spirzas, etc., around pond margins. 
Example: S. peltata. 
Porphyrion.—Prostrate in growth, the stems thickly 
clothed with tiny closely-set foliage. Flowers wide open, 
practically stalkless, generally rosy or purple. Delight

and gritty soil, but love sun so longas roots are kept moist. 
Example: S. oppositifolia. 
Robertsonia.—Rounded foliage, notched or toothed at 
edges, glossy, tall panicles of small starry flowers, sometimes 
pink, often spotted on white ground. Generally very easily 
grown in any well-drained soil, preferring some shade. 
Example: S. umbrosa.
