The Flora of the Cayuga Lake Basin 255 



The leaves vary from slightly to sharply lobed. This form was at first interpreted 

 as C. macrosperma or C. coccinea x C. pruinosa, as it combines characters of these 

 species without any pronounced new ones. However, the anthers are of a deeper pur- 

 ple than those of any other species, and the flowers are larger than those of either 

 supposed parent. The plant was found to be fairly abundant about Pulaski, N. Y., 

 where extended search failed to reveal a single specimen of C. pruinosa. For the 

 present it has seemed best to treat C. bcata as a species, but it should receive further 

 study. Certain specimens seem to indicate that it, itself, may hybridize with other 

 species. 



15. C. filipes Ashe. (C. silvicola Beadle?) 



Upland pastures and thickets, if not too dry, in gravelly soils mixed with clay; 

 frequent, and locally abundant. May 10-25, rarely to June 10; fr. Sept. 20-Oct. 



Inlet Valley, near Strattons; Michigan Hollow; V/z miles s. of Kennedy Corners; 

 n. e. slope of South Hill, frequent ; Six Mile Creek, abundant ; near Barnes Hall ; 

 Dwyer Pond (?); Ellis Hollow, n. of swamp (abundant); and perhaps elsewhere 

 nearer the lake. 



W. N. E. to cent. Mich., southw. to Pa. (Eggleston) . 



Anthers purple; fruit oval-oblong; cymes and fruit glabrous. Plants referred to this 

 species are variable, and quite possibly represent a hybrid of C. pruinosa with the vari- 

 ous forms of C. macrosperma, as the leaves have the texture of C. pruinosa and the 

 outline of C. macrosperma, while the fruit is like that of the latter species. The 

 abundance of this form, especially in certain localities where C. pruinosa is rare, as at 

 Ellis Hollow, and the general uncertainty as to its status, have led to its retention 

 here as a provisional species. The outline of the fruit of C. filipes and C. bcata in 

 this region does not agree with that stated by Eggleston. 



16. C. macrosperma Ashe. 



Upland pastures, hedgerows, and thickets, widely distributed, but more often in light 

 soils, rarely on the heavy' clay ; common. May 10-25, rarely June 5 ; f r. Sept. 10 or 

 later. 



In almost all parts of the Cayuga Lake Basin, and, with the occasional exception 

 of C. Boyntoni, the only species found in sandy chestnut soils. In gravelly soils, 

 usually associated with C. coccinea, with C. Holmesiana, and, if the soil is not too dry, 

 with C. punctata. 



N. S. and Me. to s. e. Minn., southw. to N. C. and Tenn. (Eggleston) ; occasional 

 on the Coastal Plain. 



Flowers 15-17 mm. in diam. ; fresh, unopened anthers 1.5-1.7 mm. long; disk 3-4 

 mm. in diam. ; corymbs and fruit usually glabrous ; fruit ellipsoidal to globose-oval. 

 This species as locally understood is highly variable. Several strains have been 

 detected which probably represent good varieties. C. macrosperma apparently hybrid- 

 izes with C. punctata, C. pruinosa, and probably other species. 



17. C. Holmesiana Ashe. (C. villipes Ashe.) 



Thickets and pastures, in gravelly soil but apparently not associated with chestnut 

 and Vaccinium ; frequent. May 10-30 ; fr. Sept. 



Michigan Hollow, abundant; slope of South Hill; Coy Glen and vicinity; Water- 

 burg to Mecklenburg ; s. of Trumansburg ; Cayuga Heights ; Esty ; Ellis Hollow ; 

 e. of Chicago Bog (frequent) ; Pleasant Valley, Groton; Shurger Glen; n. of Union 

 Springs. 



Me. and Que. to cent. Mich., southw. in the mts. to N. C. (Eggleston). 



Flowers few, 25-27 mm. in diam.; fresh, unopened anthers 1.9-2.5 mm. long; 

 disk 4-5 mm. in diam. Apparently a valid species, though closely related to C. 

 coccinea, and at first thought to be a hybrid of that species and C. macrosperma. 

 Opposed to this latter view are the broad sepals, more dilated than in C. coccinea.
