Woods and along streams, Canada! to Georgia! Missouri! and Ar- 

 kansas ! June-Aug. — Stem 1-3 feet high. Leaves exceedingly various in 

 their mode of division; the radical ones on long petioles; the upper eauline 

 nearly sessile ; the stipules also vary much in size. — We are not accjuainted 

 with any white-flowered American species that has a glabrous recej)tacle. 

 Perhaps the G. Virginianum of Fischer (a Meyer (G. heterophyllum, Desf.') 

 is not a native of this country. It certainly is not the original Linnsan 

 plant. — White Avens. 



•^ 2. G.macrophijllwnl^\\\(\.): hispid; stem stout ; radical leaves lyrately 

 and interruptedly pinnate ; tlie lateral leaflets obovate or roundish, unequally 

 toothed ; the terminal one much larger, roundisli-cordate ; eauline leaves 

 •with 2-4 mostly minute lateral leaflets, the terminal one large, roundish, 

 3-lobcd or parted ; the lobes rounded and very obtuse, cuneiform at the base, 

 unequally toothed ; stipules toothed or nearly entire ; pedicels rather short ; 

 bracteoles often wanting; petals (yellow) orbicular-obovate, rather longer 

 than the calyx ; carpels slightl)^ hispid at the apex ; style glabrous, the 

 upper joint a little hairy; receptacle nearly glabrous. — Willd. ! enum. 1. p.

 the hairs often reflexed, leafy often to the summit. Caqjels minutely hairy 

 or pubescent when voung, "and with a few long bristly hairs towards the 

 apex. — A wholly distinct species. Flowers intermediate in size between G. 

 Virginianum and the following. The pubescence is variable in degree ; the 

 leaves being sometimes almost glabrous. 



-^- 3. G. strictum (Ait.) : stem and petioles hirsute (hispid at the base), with 

 'spreading hairs; radical leaves interruptedly and somewhat lyrately pinnate; 

 the leaflets cuneiform-obovate, ineisely lobed and serrate; eauline leaves 

 3-5-foliolate ; the leaflets rhombic-ovate or oblong, acute, sharply toothed 

 and incised ; stipules large, incised ; flowers numerous ; bracteoles shorter 

 than the calyx-segments; petals (yellow) roundish-oval, longer than the 

 calyx ; carpels hispid at the apex ; style glabrous, the upper joint hairy ; 

 receptacle densely pubescent. — Ait. Kew. {ed. 1.) 2. p. 207 ; Willd. ! spec.
