Spec. Char., §c. Leaves obovate, obtuse, indistinctly 
3-lobed, inconspicuously 3-nerved, glaucous beneath, 
Flowers in lateral sessile umbels. A native of the 
alps of Dahuria. (Dec. Prod., ii. p. 543.) De Can- 
dolle asks whether this may not be a variety of S. 
hypericifolia ; which, we think, it most probably is. 
In Martyn’s Miller, it is said to be an intermediate 
species between S. crenata and S. triloba. Pallas 
says that it is found in Dahuria, along with S. chame- 
drifolia and S. alpina (No. 11. p. 726. fig, 432.). 
The name signifies that a leaf of this species of .. 
Spirz‘a resembles a leaflet of some kind of T'halic- fa 
trum.

corymbs of white flowers, and its distinctness in external 
character.
