 ceeding the calyx. — Enum. 716; A. Eastwood, Erythea, iv. 145. — California, Mt. Tamal- 

 pais, Congdon, Duncan's Mills, Davy. (Adv. from So. Pacific Ids.) Probably not separable

 villous with purple-glandular long white hairs : petals entire, small : fruit and seed nearly 

 as in G. dissectum. — Spec. ii. 683; Trelease, 1. c. 77. — Michigan and about New York

 in the second. 



G. pusillum, BuRM. f. Slender, spreading, soft-pubescent or the calyx, etc., somewhat 

 glandular-villous or with short glands : leaves small, round-reniform or the cauline truncate 

 at base, equally cleft into about 7 cuneate oblong lobes each more or less regularly 3-toothed 

 at apex : peduncles distributed along the stem : petals pale to deep violet, somewhat notched : 

 antheriferous stamens only 5 (exceptional in the genus) : fruit very small with puberulent

G. PtrenAicum, Burm. f. (Spec. Geran. 27), a European perennial with the aspect, fruit, 

 and seed of the last, but with obcordate petals twice as long as the calyx, appears to have been 

 collected many years ago at Bethlehem, Pennsylvania, Wolle. 



G. MOLLE, L. Resembling G. pusillum, but lower, the leaves shorter-lobed and the flowers 

 fewer, more numerous toward the top: softly and densely glandular-villous: petals deep 

 purple, obcordate : fruit as large as in the last, but the carpels glabrous and conspicu- 

 ously transversely wrinkled ; seeds slightly striate. — Spec. ii. 682 ; Trelease, 1. c. 77 ; A. 

 Eastwood, Erythea, iv. 151. — Canada to Vancouver Island, south to California, Ohio, and 

 New York. (Sparingly introd. from Eu.) Specimens with unwrinkled carpels have been
