114 POPULAK FLORA. 



following are the common wild species : they grow in woods and low meadows ; the first three blossoni 

 in summer; the fourth in early spring. 



1. ViuGiNiAN Akkmony. 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 tiie middle, new ones rising from 

 (heir axils, and so producing the blossoms all summer; sepals greenish white, acute; pistils very 

 many, in an oval woolly head. A. Vh'fjiniana. 



2. LoxG-FKUiTED 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. cylindrica. 



8. rENNSYLVANiAN 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. Pcnnsyhdnica. 



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



■or 6 leaflets; sepals white or purplish; akenes only 15 to 20, narrow. A. nemorosa. 



Meadow-Rue. Thalktrum. 



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 luis 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. 133. 



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. aneviono\de&. 



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. dioKum. 



5. Late ^L Much like the last, but 3° to 6" high; leaflets 3-lobed; flowers white, in summer. Com- 



mon in meadows and along streams. T. CornidL 



Crowfoot. Ranuncidus. 

 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 Avater. 



1. White Water-Crowfoot. 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.) 



H- Herbage all or nearly all under water. 



2. Yellow Water-C. Like the last, but larger in all its parts, and yellow-flowered, the upper leaves 



«ften out of water and much less cut. N. & W. E. Fdrshu. 



-t- -!- Not growing under water.

3. SiiALL-FLOWERED Crowfoot. Very smooth, slender ; first root-leaves crenate. B. abortivus. 



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

 b. Hook-beaked C. Hairy; leaves all 3-cleft, lobes broad; akenes with long and hooked benks, col- 

 lected into a round head. R. recurvdttcs.
