THE CAYUGA FLORA. 33 



290. C. coccinea, L. var. macracantha. (C glandulosa, Willd. of 

 most earl}' American works. C. macracantha, Lodd, probably. Re- 

 ferred by Torr. and Gray, (1840,) to C. coccinea, F. ; see Flora, I, 

 p. 465.) 



Hillsides and stony soil ; frequent. May 20-30. 



Near the Campus Brook. South Hill, beyond the " Incline," and 

 beyond S. S. 420. Both shores of Cayuga L., from Rocky Point, 

 north. Specimens from Union Springs are intermediate between 

 this form and the true C. coccinea ; nevertheless, this form, as seen 

 in Central N. Y. and elsewhere,' is so distinct from the type, that to 

 fail to distinguish it by name in some way, gives rise to more or 

 less confusion. It differs from the ordinary thin-leaved C. coccinea, 

 F., in the following particulars : Branches usually long, straggling ; 

 branchlets stout, reddish, with globose or oblate, red shining buds. 

 Thorns very long, 8-12 cm., rarely more, Leaves broadly obovate- 

 cuneiform, lobed and doubly-serrate above, tapering by a wedge- 

 shaped base into a stout petiole, coriaceous, smooth, shining, veins 

 prominent. Calyx-lobes narrowly oblong or lanceolate, pectinately- 

 glandular, while the broader calyx-lobes of C. coccinea are only 

 sparsely glandular. Flowers are smaller and more abundant than 

 in C. coccinea. Fruits smaller, not so flesh}', seeds bony and larger. 



291. C. tomentosa, F. Black Thorn. (H. and C.) 

 Hedges and moist soil ; frequent. June 5-15. 



Frequently without thorns, its calyx-lobes glandular-pinnatifid. 



292. C. tomentosa, L,., var. pyrifolia, Gray. 



Fedyard, 1827. (Herb. J. J. Thomas,) " Near Auburn" (/. Carey in 

 Flora oj N. Y. I, p. 222.) North and South of Union Springs. Its 

 leaves are rather ample, spatulate, long-petioled, somewhat shining 

 and almost regularly serrate. It is distinct from the type in time of 

 flowering (May 25-Juue 5), and in the entire glandless calyx-lobes 

 (agreeing in both these points with the following variety.) 



293. C. tomentosa, F. var. punctata, Gray. (C.) 

 Hillsides, fields, more rarely in woods ; abundant. May 25-June 5. 

 Fruit usually a dull crimson, but yellow pomes occur near Etna, 



and Forest Home; in White Church valley and near Cayuta F. 



294. C. Crus-galli, L. Cock-spur Thorn. (H. and C.) 

 Pastures and fences. 



Frequent near Cayuga F. from a region south and east of Fudlow- 

 ville to Montezuma ; also west and north of Sheldrake and Canoga ; 

 elsewhere absent. 



118. Ameeanchier, Medic. 



295. *A. Canadensis, Torr. and Gray, (including var. botryapium.) 

 June-berry. Shad-bush. (H. and C.) 



Ravines and woods ; frequent. May 1-20. 



On Univ. farm (a large tree, the young leaves hairy.) Fall Cr., 

 Case. Cr., Eddy Pond, Six Mile Cr., Big Gully, etc., (all with young 

 leaves nearly glabrous.) 



296. A. Canadensis, Torr. and Gray. var. oblongifolia, Gray. (C.) 

 Ravines and woods ; common. May 1-20.
