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. V'lKGixiAN Anemonv. Principal stem-leaves 3 in a whorl, on long footstalks, 3-parted and cut- 



lobed, hairy; middle flower-stalk leafless, the others 2-lcaved 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. Vivyiniana. 



2. LoNG-FKUiTED A. Stcm-lcaves 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. cylindrica. 



3. Pexnsylvanian 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. Fennsykdnica. 



4. Grove A. Smooth, low, one-flowered; stem-leaves 3 in a whorl, on long footstalks, divided into 3 



or 5 leaflets; sepals white or purplish ; akenes only 15 to 20, narrow. A. nemorosa. 



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 Anemony, except for its 

 ribbed akenes, and has a few handsome and perfect flowers in an umbel. The other two have small 

 and mostly dioecious flowers in a compound panicle, and decompound leaves ; one of the lower leaves 

 is shown in Fig. 133. 



1. Anemony M. Low, dehcate ; 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. anemonmdes. 



2. Early 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. diuicum. 



3. Late M. Much like the last, but '3° to 6° high; leaflets 3-lobed; flowers white, in summer. Com- 



mon in meadows and along streains. T. Cornuii. 



Crowfoot. Ranuncnhts. 

 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. White WATEE-CRO^yFOOT. Leaves made up of many delicate thread-like divisions. R. aqudlilis. 



* * Petals yellow, and with a little scale on the inside at the bottom. (Fig. 239.)

4. Cursed C. Very smooth, stouter ; leaves all cleft or lobed ; head of fruits oblong. R. sceleratus.
