1906] Fernald, A new Geum from Vermont and Quebec 1 1 



A NEW GEUM FROM VERMONT AND QUEBEC. 

 M. L. Fernald. 



In June, 1898, Mr. W. W. Eggleston collected at Mendon, Vermont, 

 a Geum which he sent without name to the Gray Herbarium. The 

 specimen was in anthesis, and without detailed examination was 

 passed as Geum inacropliyllurn Willd. 



On July 6 last, however, a Geum quite like Mr. Eggleston's Mendon 

 plant was found by Messrs. E. F. Williams, J. F. Collins and the 

 writer in a boggy meadow by the St. Lawrence at Bic in the County 

 of Rimouski, Quebec. At Bic the plant which was nearly past anthe- 

 sis attracted immediate attention by its large wide-spreading crimson 

 calyx, deep claret-colored styles, and the strongly contrasting broadly 

 obcor'date bright yellow petals; and only in the outline of the leaf did 

 it suggest the common Geum macroph/llum of the lower St. Lawrence 

 and northern New England. That well-known plant abounds at 

 Bic and a superficial examination was sufficient to show that, in its 

 small green recurved calyx, its greenish or barely crimson-tinged 

 styles, and its small narrow pale petals, it had little in common with 

 the plant now seen growing for the first time. 



Detailed study of the new plant shows that its only immediate alUes 

 in America are Geum rivale L. and G. geyiiculatum ISIichx., while in 

 many characters it is nearer the Scandinavian species, G. hispidum 

 Fries and G. intermedium Ehrh. To none of these species does the 

 plant of Bic and Mendon seem to be referable, and it has been impos- 

 sible to find any plant to which it is more closely allied. It is appar- 

 ently a somewhat local representative of Seringe's section Cariophyllata, 

 which may be sought with confidence elsewhere in New England and 

 eastern Canada, and which on account of the effective contrast of 

 colors in its flowers may be called 



Geum pulchrum sp. n. Caule erecto piloso-hispido apice glandu- 

 loso-puberulo 4-11-floro; foliis radicalibus interrupte pmnatisectis 

 subtus hispidis lobis obovatis dentatis, foliis cauhms trilobis lobis 

 obovatis; stipulis anguste ovatis argute serratis; pedunculis pur- 

 purascentibus tenuibus; floribus nutantibus; calyce purpurascente, 

 laciniis patentibus deltoideo-ovatis ; petalis suborbicularibus obcor- 

 datis flavis; filamentis badiis vel purpurascentibus ; carpelhs setosis, 

 stylis elongatis valde purpureis geniculatis, appendicibus plumosis 

 coccineis.
