THE CAYUGA FLORA. 83 



Occurs in all our ravines, and near the cliffs of the lake shore. 

 "Ithaca," {Herb. Sartwell.) 



337. Cannabis, Touru. 



805. C. sativa, L. Hemp. (H. and C.) 

 Rich, waste soil ; scarce. July- Aug. 



Near Cascadilla Place. Six Mile Creek, near Ithaca. Forest 



Home. 



338. Humueus, Linn. 



806. H. Lupulus, L. Hop. (H.andC.) 

 Along banks of streams, and in swamps ; scarce. July. 



Island in Beebe Pond. Near mouth of Coy Glen. Near Fall 

 Creek, east of Freeville. Round Marsh and several places in the 

 interior of Beaver Creek Swamp, where it is manifestly native. 



PLATANACE^E. 



339. PeaTanus, Linn. 



807. * P. occidentalis, L. BuTTONWOOD. SYCAMORE. (H. and C.) 

 Woods, especially in alluvial soil ; frequent. June. 



Along Cascadilla and other creeks. These trees — some of them 

 of great size — formerly gave to Negundo Woods the aspect of the 

 western bottom-land woods. 



JUGLANDACE.E. 



340. JUGEANS, Linn. 



808. *J. cinerea, L. Butternut. (H.andC.) 

 Ravines and rich uplands ; frequent. May 15-30. 



809. *J. nigra, L. Beack Waenut. (H. and C.) 

 Roadsides, fields ; rarely in ravines ; scarce. May 15-30. 

 Scattered trees have been observed in about a dozen localities 



within limits, but in none is the species clearly indigenous except 

 possibly a station along a creek in Fayette. The tree nearest the 

 Campus is on Factory street. 



341. Carya, Nutt. 



810. *C. alba, Nutt. Shagbark-Hickory. (H. and C.) 

 Woods and slopes ; common. May 15-June 10. 



Campus, northwest of the chapel, and west of the Engineering 

 Building ; and elsewhere, in woods. 



811. C. microcarpa, Nutt. White Hickory. (Dr. Wright in C.) 

 Hillsides ; not uncommon. May 15-June 10. 



Frequent on the Campus, (excellent examples in front of Dr. 

 Law's residence.) Cayuga L. west shore, in Stevens' woods; also 

 near Crobar Point and in Wayne's Woods near Canoga. Woods 

 near Eagle Hill and Snyder Hill. 



This species is reduced to C. alba, Nutt, by some. In this region 

 it is clearly distinct from that species ; its affinities being with C. 

 tomentosa, Nutt., and C porcina, Nutt. It also agrees clearly with a 

 large series of specimens of C. microcarpa, at the U. S. G. Herb. 

 at Washington, received from different parts of the Union, and is 

 not essentially different from Nuttall's figure and description. I re- 

 retain it as a distinct species, because its suppression would be con- 

 fusing to any student of our local plants.
