A.* sphenoph^Ua, P(epp. Habit and most of the characters of the last : leaves glabrate 

 or nearly so, 3-foliolate ; divisions commonly cleft into rather narrow sometimes even linear- 

 lanceolate acutish segments ; leaves of the involucre (with rare exceptions) sub-.similar to 

 the basal leaves in outline and segmentation, and not so strikingly reduced in size as in the 

 preceding : flowers sometimes solitary but more commonly 2-3(-4) from the same involu- 

 cre. — Frag. Syn. 27 ; Britton, 1. c. 220 ; Coville, Contrib. U. S. Nat. Herb. iv. 56. A. decapetala,

A. Caroliniana, Walt. A span or two high from a globular small tuber (which is pro- 

 duced at the apex of a flagelliform subterranean shoot) : slender stem one-ilowered, usually 

 bearing the simply palmatifid involucre much below the middle : sepals purple, blue, or 

 white: head of carpels short-oblong or barely cylindraceous in fruit (usually half inch 

 long) : style about the length of the ovate rather turgid akene, erect, its slender tip pro- 

 jecting from the wool, more deciduous. — Car. 157; Torr. & Gray, 1. c. 12 (excl. var. 

 heterophylla) ; Torr. in Marcy, Rep. t. 1 ; Meehan, Native Flowers, ser. 1, i. 165, t. 42. 

 A. tenella, Pursh, Fl. ii. 386. — Sandy soil, Florida to N. Carolina, Illinois, Dakota, and 

 soutliwest to Texas, thus partly accompanying the preceding but in different soil ; fl. early 

 spring. 

 A. WAlteri, Pursh, Fl. ii. 387, founded wholly on Walter's character of his Thalictrum 



Carolinianum, is quite obscure, no specimen being extant. If an Anemone it might be referred 



to A. Caroliniana, except for tiie pentasepalous flower. 



-1— -1— -1— Plants 1 to 3 feet high from a caudex, few-several-flowered : sepals mostly 5, oval 

 or obovate, seldom over half inch long, white or greenish white, sericeous-canescent out- 

 side : style subulate, shorter and stout, wholly or mainly persistent on the semi-obovate 

 akene : involucral leaves similar to the radical and petioled, palmately or pedately 3-5- 

 divided and the divisions 2-3-cleft and incisely toothed ; fl. summer. 



A. cylindrica, Gray. Somewhat silky-pubescent, strict : divisions and lobes of the leaves 

 mostly cuneate-lanceolate : involucre in depauperate plants 3-5-leaved and 1-2-flowered, but 

 usually 5-9-leaved and 2-6-flowered, with very long and naked umbellate peduncles (the 

 involucels if any being basal and making a part of the general involucre), or occasionally 

 one of the peduncles involucellate at the middle : head of carpels in fruit cylindrical, inch or 

 more long, very woolly; the short somewhat recurved styles slightly projecting. — Ann. 

 Lye. N. Y. iii. 220; Torr. & Gray, Fl. i. 13. — Dry ground. New Brunswick to Montana and 

 Saskatchewan, south to New Jersey and New Mexico, 



A. "Virginiana, L, More loosely pubescent or glabrate: divisions and lobes of the leaves 

 rliombic-ovate or ovate-lanceolate : involucre 2-3-leaved, subtending a solitary and elongated 

 naked peduncle and one or sometimes two proliferous ones, i. e. involucellate at the middle, 

 and tliese again often proliferous, thus continuing long in l)los.som : sepals usually greenish 

 white and only lialf inch long, sometimes enlarging and bright wliitc : head of carpels in 

 fruit ovate or oblong, tiiick, as it were muricate by the jjrojection of the conspicuous .stout 

 styles, the apex of the akenes also naked. — Spec. i. 540; (j!a;rtn. P'ruct. i. t. 74; Hook. V\. 

 Bor.-Am, i. 7, t. 4 ; Torr. & Gray, 1. c. ; Meehan, Native Flowers, ser. 2, i. 93, t. 23. A. hirsuta, 

 Moench, Meth. Suppl. 105. — Moist ground. New Brunswick to S. Carolina, and northwest to 

 the Rocky Mountains and lat. 55°. 



* * Akenes naked (when mature), orbicular, much compressed, wing-margined : sepals 

 5, obovate, wliite, lialf inch or more long : involucre closely sessile, palmately parted or 

 cleft.
