Lower leaves expanding, reflexed, upper one about the length of the joints. 
Stamens four, five, or seven. Petals purple. Seeds flat, between half 
heart-shaped and kidney-shaped, the circular edge downy, with an ele¬ 
vated rounded border, the straight edge plain, dark brown; some com¬ 
passed with a membranous border, deeper than half the breadth of the 
. seed, white, with radiated, scores, toothed at the edge. So remarkable 
a difference in structure one might have expected to afford a mark of 
specific distinction, but though generally the two kinds of seeds are 
found on different plants, yet they are sometimes seen in the same seed- 
vessel. St. Spergula maritima Jlore parvo cceruleo , semine vario. Ray

It is not clear that this plant of Ray and Hudson is the A. media of Linn. 
It may be only a var. of A. marina. (A further examination of speci¬ 
mens and figures induces me to suspect it may prove A. marina /3, 
FI. Brit, instead of the first variety as Smith seems to imagine. E.) 
A. ver'na. Leaves awl-shaped, bluntish: stems panicled: (petals 
obovate, longer than the remotely three-nerved calyx. E.)

A.juniperina and laricifolia have no pretensions to be considered British

has the peculiar power of resisting the deleterious effects of the metallic oxides which usually 
pervade the refuse heaps thrown out from mines, and is found to flourish in such situations, 
usually destructive to vegetable life. JE.)
