114 POPULAR FLORA. 
following are the common wild species: they grow in woods and low meadows; the first three blossom 
in summer; the fourth in early spring. 
1. Vireinian ANEMONY. Principal stem-leaves 3 in a whorl, on long footstalks, 3-parted and cut- 
lobed, hairy; middle flower-stalk leafless, the others 2-leaved in the middle, new ones rising from 
their axils, and so producing the blossoms all summer; sepals greenish white, acute; pistils very 
many, in an oval woolly head. A. Virginiana. 
2. LonG-FRUITED A. Stem-leaves many in a whorl; flower-stalks 2 to 6, all leafless, very long; sepals 
blunt; head of fruit (an inch) long: otherwise like the last. N. & W. A. cylindréea. 
8. Pennsytvantan A. Hairy; stem-leaves sessile; main ones 3 in a whorl, but only a pair of smaller 
ones on each of the side flowering branches; sepals large, white or purplish; akenes flat, many in 
a round head. A. Pennsylvdnica. 
4. Grove A. Smooth, low, one-flowered; stem-leaves 3 in a whorl, on long footstalks, divided into 3 
or 5 ppetetss sepals white or purplish; akenes.only 15 to 20, narrow. A. nemorésa. 
Meadow-Rue. Thalictrum. 
Sepals 4 or more, petal-like or greenish. Real petals none. Pistils 4 to 15, becoming ribbed or 
grooved akenes. — Perennials, with compound leaves. No. 1 is almost an Auemony, except for its 
ribbed akenes, and has a few handsome and perfect flowers in an umbel. The other two have small 
and mostly dicecious flowers in a compound panicle, and decompound leaves; one of the lower leaves 
is shown in Fig. 138. 
1. Anemony M. Low, delicate ; stem-leaves all in a whorl at the top; sepals 7 to 10, white or pink- 
ish, like those of Grove Anemony, with which it generally grows. Fl. spring. T. anemonoides. 
2. Earty M. Plant 1° or 2° high; leaves all alternate, the rounded leaflets with 5 to 7 roundish lobes; 
flowers greenish, in early spring. Woods. T. diotcum. 
8. Late M. Much like the last, but 8° to 6° high; leaflets 3-lobed; flowers white, in summer. Com- 
mon in meadows and along streams. T. Corniti. 
Crowfoot. Raninculus. 
Sepals 5, falling early. Petals 5 (sometimes accidentally more), flat. Akenes many in a head, flat. 
* Petals white, with a round spot at the base : herbage all under water. 
1, Weitz Warer-Crowroor. Leaves made up of many delicate thread-like divisions. R. aqudtilis, 
* * Petals yellow, and with a little scale on the inside at the bottom. (Fig. 239.) 
++ Herbage all or nearly all under water. : 
2. YELLow Warer-C. Like the last, but larger in all its parts, and yellow-flowered, the upper leaves 
often out of water and much less cut. N. & W. R. Pirshii.

8. SMALL-FLOWERED CRowroot. Very smooth, slender ; first root-leaves crenate. R. abortivus. 
4. CursED C. Very smooth, stouter ; leaves all cleft or lobed; head of fruits oblong. RR. sceleratus. 
5. Hoox-BEAKED C. Hairy; leaves all 8-cleft, lobes broad; akenes with long and hooked beaks, col- 
lected into a round head. R. recurvatus.
