CAYUGA FLORA (1926) NOTES: Damp sandy or gravelly banks and shores; frequent. Aug.-Sept. Widely distributed in N. A. except in the colder parts of Canada. Found also in Eu. and Cent. Am., and perhaps in other countries. The following forms are found in the Cayuga Lake Basin: (1) Burs glabrous or minutely puberulent and atomiferous, fusiform, averaging somewhat smaller than in the other forms (X. chinense Mill., X. pungens Wallr., X. glabratum Britton, X. americanum Britton & Br., possibly Walt., X. canadense of Grays Man., ed. 7, and of Cayuga Fl. (2) Burs more or less hispid, the body ellipsoidal with generally prominent beaks (X. italicum Mor., X. pennsylvanicum Wallr., X. commune Britton and of Grays Man., ed. 7, X. canadense var. echinatum, in part, of Cayuga Fl.). (3) Burs hispid, the body ovoid, broadly elliptic-ovoid, or oval, the beaks less prominent (X. glanduliferum Greene?, X. canadense var. echinatum, in part, of Cayuga Fl., X. echinatum, in part, of Grays Man., ed. 7). (4) Spines far apart and few in number, otherwise generally as in no. 2 (X. Wootoni Cockll.). The spines in this last-named form vary in number toward the normal, and the plants occur as individuals in otherwise normal colonies. In each of the above-named forms the spines vary greatly in shape and abundance.
