A BRITISH BOTANY. 
GENUS I.—THALICTRUM. Linn. 
Involucre none. Sepals 4or 5, petaloid, caducous. Petals none. 
Stamens definite or indefinite. Ovaries numerous. Achenes stipitate. 
Styles deciduous or none. Leaves alternate, ternately decompound. 
This genus is probably allied to the Helleboridee, and may be 
considered as a form of that group, having the ovules reduced to 
one, and the fruit indehiscent.

England, Scotland, Ireland. Perennial. Summer. 
The smallest species of the genus, with slender wiry stems, 3 to 
9 inches high, with short stolons at the base, and biternate-stalked 
leaves, which are mostly radical, though in luxuriant specimens 
there is often one or more situated on the lower part of the stem. 
Leaflets small, roundish, bluntly serrated, much less variable in 
shape than in the other British species, deep green above, whitish 
below. Flowers in a simple terminal raceme, which is drooping at 
the point before the flowers open, then becoming erect, while the 
individual flowers droop: these are small, with 4 pale purplish- 
brown sepals, and 8, 10, or more long pendent stamens, with yellow 
anthers. Fruit of 2 or 3 narrowly-oblong ribbed achenes, thick- 
ened at the point, which is bent outwards by the carpel bulging on 
the inner side near the end. Bracts small, lanceolate, entire.
