Betulaceae

CAYUGA FLORA (1926) NOTES: Upland or damp lowland thickets ; occasional. Apr. 20-May 20. Knoll near D., L. & W. switchback, Six Mile Creek ; Beebe Lake ; Turkey Hill; woods n. of Cayuga Heights ; Taughannock Gorge ; Fox Ridge ; s. end of Westbury Prairie ; and elsewhere. Native: Que. to Alaska, southw. to Me., Ill., and Man. Found also in Eurasia. A circumpolar species of the Far North, coming south locally in the U.S. Many forms are in cultivation as ornamental trees, and escape occasionally to woods and%0D%0Athickets. At all the above stations the plant is unquestionably introduced. At Fox Ridge, where it forms a forest of several acres, it seems to have been planted or sown on previously cultivated ground. The cut-leaved forms of this species are var. dalecarlica Schneid. and var. gracilis Rehd. Apparently these forms have not escaped from cultivation. B. pendula differs from B. populifolia in the more rounded-ovate, less acuminate leaves, less glandular twigs, longer pistillate catkins with longer (3-5 mm.), less divaricate scales, and clustered staminate catkins. The New York State specimens of B. pendula have puberulent pistillate scales.
