torted, clothed with short bristly hairs. Calyx-segments slightly 
hairy inside. Plant otherwise glabrous, deep-green. 
Dropwort. 
French, Spirée Filipendule. German, Knollentragendes Madesiiss. 
Dr. Withering says that the common name of this plant is suggested by the 
tuberous pea-like roots hanging by slender threads, which, when dried and reduced to 
powder, make a kind of bread, which in times of scarcity is not to be despised. Hogs 
are very fond of these roots. In cultivation this plant is a pretty addition to the 
flower-garden, and will grow in any kind of soil, preferring, however, a moist situation. 
Trips II—SANGUISORBESA. 
Herbs, rarely undershrubs or shrubs, with simple, digitate, or 
more commonly pinnate leaves. Calyx bell-shaped or funnel-shaped, 
contracted at the throat; segments persistent. Petals none, or 
rarely present and then yellow. Stamens definite, 1, 2, or 4 in 
number, or indefinite. Carpels 1 to 4, enclosed in the tube of the 
calyx, but not adhering to it. Style lateral or terminal. Fruit of 
1 to 4 dry achenes, enclosed in the indurated tube of the calyx. 
GENUS TTTI—AGRIMONIA. Tournef. 
Flowers perfect. Calyx-tube turbinate, with an annular con" 
traction at the throat extending on the outside into a ring bearing 
numerous rows of slender hooked spines, 10-furrowed and indurated 
at maturity; segments 5, connivent after flowering, in a single 
row. Petals 5, inserted in the throat of the calyx. Stamens 12 
to 20, inserted immediately within the petals. Ovaries 2, rarely 3. 
Styles terminal, exserted. Achenes 1 or 2, rarely 3, enclosed in the 
hardened tube of the calyx. 
Perennial herbs, with alternate interruptedly-pinnate leaves, 
and foliaceous stipules adnate to the petiole. Flowers yellow, in 
terminal spike-like racemes. 
The derivation of the name of this genus is variously given by different writers. 
Perhaps the most reliable statement is that it comes from the word aypvoc, wild, from 
its abundance in fields and hedges. It is said also to be a corruption of argemone, a 
name given by the Greeks to a plant which was supposed to cure cataract of the eye, 
from apyoc (argos), white, the cataract of the eye being a white film.
