114 POPULAK PLOKA. 



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. Virginian 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-FKUITED A. Stem-leaves many in a whofl ; 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. Pennsylvanian 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, Pennsyhdnica. 



4. Ghove 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 16 to 20, narrow. A. nemorosa. 



Meadow-Rne. Thalicirum. 

 Sepals 4 or more, petal-like or greenish. Keal 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. Ais'EMONY 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. anemonmdes. 



2. Eakly j\I. Plant 1° or 2° high ; leaves all alternate, the rounded leaflets with 5 to 7 roundish lobes; 



flowers greenish, in early spring. Woods. , T. dioicum. 



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 streams, T. Coimiiti, 



Crowfoot. Ranunculus. 



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 Watek-Ckowfoot. Leaves made up of many delicate thread-like divisions. R. aqudtilu. 



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

 ■i- Herbage all or nearly all under water. 



2. Yello-w Watek-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, Pilrsliii. 



t- ^- Not growing under water. 

 ,-► Petals not longer, but often shorter, than the calyx : plants erect, in wet places. 



3. Small-floweeed Crowfoot. Very smooth, slender ; first root-leaves crenate. R. abor&vm. 

 i. Cursed C. Very smooth, stouter ; leaves all cleft or lobed; head of fruits oblong. R. scela-aius. 

 6. Hook-beaked C. Hairy; leaves ail 3-cleft, lobes broad; akenes with long and hooked beaks, col- 

 lected into a round head. J2_ recurvdtVfS. 



6. Bristly C. Stout, bristly-hairy; leaves divided into 3 or B stalked leaflets, which are cleft and out 

 again into narrow lobes ; akenes straight-beaked, in an oblong liead. R. Pemisylvdnicus.
