tite.—An erect herb, with a habit between Séseli and Gindnthe, 
but differs from the first in the teeth of the calyx being obso- 
lete, in the petals being broad-ovate, not obovate, and in the 
ribs of the fruit being less prominent; and from the last in the 
shape of the petals, in the styles and in the carpophore being 
present. 
1 S. Meve'‘rs (Led. 1. c.). %.H. Native of Siberia, at the 
river Irtysch, not far from the lake called Noor-Saisan; and at 
the river Bekin, in sandy places. Root fusiform. Stem erect, 
striated, simple at the base, and usually bearing 3-4 verticillate 
branches at the apex ; branches leafless, or furnished with mem- 
branous scales in the middle. Radical leaves 3-4, tripinnate: 
leaflets linear; cauline leaves 1-2. Umbels of 10-15 rays, of 
these 4 are longer than the rest. Involucra wanting, rarely 
of 1 leaf; involucels of 6-8 leaves, which are ovate-lanceolate, 
pilose on the outside, and ciliated, shorter than the umbellules. 
Flowers sessile in the umbellules: outer ones female: interme- 
diate ones hermaphrodite : central ones male.

Lin. syst. Pentandria, Digynia. Margin of calyx 5-toothed ; 
teeth short, thickish, and sometimes obliterated. Petals ob- 
ovate, coarctate into an inflexed point at the apex, emarginate or

nate or ternately decompound. Involucrum wanting or almost so; 
involucels of many leaves. Flowers white, very rarely yellow.
