Geum & Sieversia, R. Br.
Calyx rather flat or obconic at the base, deeply 5-cleft, usually with 5
exterior alternate segments or bracteoles. Petals 5, obtuse or emarginate.
Stamens numerous, inserted into the disk which lines the base of the calyx
in nearly a single or in several rows: filaments somewhat persistent.
Achenia numerous, aggregated on the conical or cylindrical dry (glabrous or
hairy) receptacle, caudate with terminal persistent styles: stigmas simple or
retuse. Seed erect. Radicle inferior.—Perennial herbs, with variously
pinnately divided leaves. Flowers white, yellow, or purplish.
§ 1. Flowers erect (mostly small): segments of the calyx rejlexed: head of
carpels sessile: styles articulated and geniculate above the middle; the
lower portion glabrous, persistent, uncinate at the apex after the dejlexed
and mostly hairy terminal portion falls away.—E ugeum. (Caryophyl-
lastrum & Calligeum, Fisch. Sf Meyer.
1. G. Vifginianum (Linn.) : stem somewhat hirsute or sometimes nearlv
glabrous above ; radical leaves pinnate, or lyrately pinnate with the lateral
leaflets minute, or rarely simple and undivided ; cauline ones 3-5-foliolate or
lobed, toothed or serrate, softly pubescent or somewhat glabrous; stipules
mostly toothed; peduncles diverging and elongated in fruit; bracteoles
minute; petals (white) about the length of the calyx, cuneate-obovate;
carpels sparingly hispid ; style glabrous, the upper joint hairy at the base;
receptacles densely hirsute.—Linn.! spec. 1. p. 500 ; Murr. in comm. Gostt.

Woods and along streams, Canada! to Georgia! Missouri! and Arkansas
! June-Aug.—Stem 1—3 feet high. Leaves exceedingly various in
their mode of division; the radical ones on long petioles; the upper cauline
nearly sessile; the stipules also vary much in size.—We are not acquainted
with any white-flowered American species that has a glabrous receptacle.
Perhaps the G. Virginianum of Fischer & Meyer (G. heterophyllum, Desf.)
is not a native of this country. It certainly is not the original Linnaean
plant.— White Avehs.
2. G. macrophyllum (Willd.): hispid; stem stout; radical leaves lyrately
and interruptedly pinhate; the lateral leaflets obovate or roundish, unequally
toothed; the terminal one much larger, roundish-cordate; cauline leaves
with 2-4 mostly minute lateral leaflets, the terminal one large, roundish,
3-lobed 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 slightly hispid at the apex; style glabrous, the
upper joint a little hairy; receptacle nearly glabrous.— Willd. ! enum. 1. p.

July.—Stem 1-2 feet high, very hispid, as well as the leaves, when young,
the hairs often reflexed, leafy often to the summit. Carpels minutely hairy
or pubescent when young, 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, incisely lobed and serrate; cauline 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.
