206 GERANIACEiE. Geraniom. 



1. GERANIUM. Linn, (in part) ; VHer.; Gcertn. fr. t. 79. 



Sepals equal. Petals 5, equal. Stamens 10, all fertile; alternate ones 

 larger, with a nectariferous gland at their base. Persistent styles at length 

 circinately revolute, glabrous within. — Herbaceous or rarely suffrutescent. 

 Peduncles 1-2-ilowered (2- rarely 3-tiowered in the North American species). 



♦ Pere7inial. (Pubescence of the stem and petioles rttrorse in the North American 



species.) 



'^' 1. G. maculatimi (Linn.) : stem erect, (often nearly glabrous below) di- 

 chotomous, somewhat angled, pubescent ; leaves 3-5-parted ; the segments 

 acute, cuneiform below, incisely serrate above ; the radical leaves on long 

 petioles; uppermost opposite; petals entire; filaments scarcely ciliate at the 

 base. Hook.—Michx. I ji. 2. p. 157 ; Ell. sk. 2. p. 157 ; Bigel. med. bot. t. 8 ;

In open woods, &c. Canada! to Florida; Avest to the Mississippi. April- 

 June. — Stem 1-2 feet high. Leaves hirsutely pubescent ; the lobes incisely 

 toothed or cleft. Pedicels unequal. Sepals oblong or oval-lanceolate, mucro- 

 nate-awned, sparsely clothed with long white hairs: pubescence not glandu- 

 lar. Petals large, purple (sometimes almost white), cuneiform-obovate, 

 densely villous with short hairs at the base. Seeds minutely reticulated. — 

 Crow-foot. Spoiled Cranes-bill. 



n 2. G. albifiorum (Hook.) : stem erect, dichotomous, somewhat angled, 

 glabrous below; glandular-pilose above; leaves deeply .5-parted; segments 

 ovate, acuminate, incisely subpinnatifid, rather hairy ; radical ones on long 

 petioles ; the uppermost opposite, on short petioles, 3-parted, rather acuminate ; 

 sepals glandular-pilose ; petals (entire, white) as well as filaments hirsute at 

 the base. Hook. I. c. p. 116, t. 40, f in bot. mag. t. 3124. 



13.7 incisum : leaves almost 5-divided; segments narrower; flowers pur- 

 ple. — G. incisum, Null.! mss. 



Vallies of the Rocky Mountains, Drummond ! — Nearly allied to G. macu- 

 latum and G. pratense. Hook. — /?. VaUies of the Rocky Mountains and 

 Oregon, Nutlall ! — A portion only of the hairs on the peduncles, sepals, &c. 

 is glandular; and the pubescence is much denser and shorter than in G. 

 maculatum. We have the same plant from Altaic Siberia, sent by Prof. 

 Fischer. Thevar. 0.1 which we doubt not is wholly distinct from G. macula- 

 tum, may perhaps prove to be distinct from G. albiflorum. The petals have 

 a lateral tuft of hairs at the base. 



' 3. G. erianthum (DC.) : stem erect, angled, (terete, DC.) sparingly dicho- 

 tomous, minutely pubescent or nearly glabrous below ; leaves deeply 5-7- 

 lobed ; lobes 3-cleft ; segments laciniate-incised ; radical ones on long pe- 

 tioles ; the uppermost subsessile ; peduncles short and crowded; sepals and 

 base of the petals and stamens densely villous. — DC. prodr. 1. p. 641 ;

N. W. Coast & Kamtschatka, De Cand. Hook. ^ Am. Sitcha, Bon- 

 gard I — Flowers purple ("perhaps blue," Bongard\ the size of G. macula- 

 tum. Sepals narrower than in the 2 preceding species, verv hirsute ex- 

 ternally with long white hairs; the same kind of pubescence also on the base 

 of the filaments. — These 3 species, it would seem from our specimens, may 

 be further distinguished by the villosity of the petals ; which in G. macula- 

 Jum forms a small and very dense white tuft on the claw inside ; in G. albi-
