36 CROWFOOT FAMILY. 



§ I . Long hairy styles form feaihery tails to the aJcenes, like those of Virgin's- 

 Bower: fl. large, purple, in early spring. The genus Pdlsatilla of some 

 authors. 

 A. Pulsatilla, Pasque-flower, of Europe. Cnlt. in some flower-gar- 

 dens ; has the root-leaves finely thrice-pinnately divided or cut ; otherwise much 

 like the next. 



A. p&tens, var. Nuttallitoa, Wild p. On the plains N. W. ; the 

 handsome purple or purplish flower (2' or more across when open) rising fiom 

 the ground on a low soft-hairy stem (3' -6' high), with an involucre of many 

 very narrow divisions ; the leaves from the root appearing later, and twice or 

 thrice-ternately divided and cut. 



§ 2. Short styles not mak'ing long tails, hut only naked or hairy tips. 

 # Garden ANEMOiHES,y)'om S. Eu., with tuberous roots and very large flowers. 



A. COron^ia, with leaves cut into many fine lobes, and 6 or more broad 

 oval sepals, also 



A. nort^nsis, with leaves less cut into broader wedge-shaped divisions and 

 lobes, and many longer and narrow sepals, — are the originals of the showy, 

 mostly double or semi-double, great-flowered Gakden Anemonies, of all col- 

 ors, red in the wild state, — not fully hardy, treated like bulbs. 

 * * Wild species, smallerflowered. 

 1-. Pistils very many, forming a dense woolly head in fruit : leaves of the involucre 

 lortg-petiolea, compound : flowers of 5 small greenish-white sepals, sillcy beneath : 

 stem 2° -3° high. 



A. oylindrica, Long-pruited A. Involucre severaHeaved surrounding 

 several long naked peduncles; fl. late in spring (in dry soil N. & W.), followed 

 by a cylindrical head of fruit. 



A. Virgini^na, Virgikian A. Involucre 3-leaved ; peduncles formed in 

 succession all summer, the middle or first one naked, the others bearing 2 leaves 

 (involucel) at the middle, from which proceed two more peduncles, and so on : 

 head of fruit oval or oblong. Common in woods and meadows. 



-I- ^- Pistils fewer, not woolly in fruit : flower V or more broad. 

 • A. Pennsylv&nlea, Penh-stltanian A. Stem \° high, bearing an invo- 

 lucre of 3 wedge-shaped 3-cleft and cut sessile leaves, and a naked peduncle, then 

 2 or 3 peduncles with a pair of smaller leaves at their middle, and'so on ; fl. white, 

 in summer. (Lessons, fig. 179.) Alluvial ground, N. & W. 



A. uemordsa. Wood A. Stem 4' -10' high, bearing an involucre of 3 

 long-petioled leaves of 3 oi: 5 leaflets, and a single short-ped uncled flower ; sepals 

 white, or purple outside. Woodlands, early spring. 



4. THALICTRTJM, MEADOW-RUE. (Old name, of obscure deriva- 

 tion.) The following are the common wild species, in woodlands and low 

 grounds. 



§ 1. Flowers perfect,few, in an umbel: resembling an Anemone: sepals 5-10. 



T. anemonoides, Rue-Anemone, a very smooth and delicate little 

 plant, growing with Wood Anemone, which it resembles in having no stem- 

 leaves except those that form an involucre around the umbel of white (rarely 

 pinkish) flowers, appearing in early spring ; leaflets roundish, 3-lobed at the 

 end, long-stalked ; ovaries many-grooved, and with a flat-topped sessile stigma : 

 otherwise it would rank as an Anemone. 



§ 2. Flowers mostly diacious and not handsome, smcdl, in loose compound panicles ; 

 the 4 or 5 sepals falling early : stigmas slender : akeiies several-grooved and 

 ' angled: leaves ternately decompo>md\jjessoJis, &g. 138), all alternate; theitpper- 

 most not forming an involucre. 



T. dioicum, Early Meadow-Rue. Herb glaucous, l°-20high; flow- 

 ers greenish, in early spring ; the yellowish linear anthers of the sterile plant 

 hanging on long capillary filaments : leaves all on general petioles. Rocky 

 woods. 



T. purpuriscens, Pukpush M. Later, often a little downy, 2° -4°
