THE CAYUGA FLORA. 87 



According to Mr. Lewis of W. Hill, "Red Beech" is the form 

 growing in drier soil and somewhat dwarfed ; " White Beech," the 

 form — larger, and of more rapid growth — occurring in richer soil. 



SALICACE^. 

 351. Salix, Tourn. Willow. Osier. 



837. S. nigra, Marshall. Black Willow. (H. and C.) 



Along streams and low shores ; common. Flowers May 20-June 1. 



Case. Cr. Especially abundant Six Mile Cr. and Neguaena Cr. and 

 at the head of Cayuga Lake, where it grows in great masses. Its 

 slender bright, green leaves, borne in great abundance help to re- 

 lieve the flat, shore lines more than any other willow. A form with 

 thick, elliptical leaves more woolly on the petiole and branchlets is 

 found near Canoga and elsewhere. The form known as var. falcata 

 is occasional. 

 S38. S. amygdaloides, Andersson. {Salices Boreali-Americance,va.Proc. 

 Amer. Acad, of Arts and Set., Vol. IV.) (S. nigra, Marsh, var- 

 amygdaloides, Anderss. Mon. Sal. p; 21.) Peach Willow. 



" Leaves broadly lanceolate, 3 / -6 / long, J^-iK' wide, with a long, 

 tapering point, glaucous beneath, closely serrate, petioles long and 

 slender, stipules minute and very early deciduous. Aments, leafy 

 peduucled, elongated-cylindrical, pendulous ; the fertile, when in 

 fruit, lax, 3 / -4 / long, y^' thick ; scales in the male anient ovate, 

 villous with crisp hairs, in the female narrower, somewhat smooth, 

 fugacious : Capsules globose-conical, glabrous, long-pedicelled ; 

 Style very short or obsolete ; stigmas notched," (Bebb, in the Botany 

 of the Wheeler Survey, West of the 100th Meridian, p. 240.) Anders- 

 son says the flowers are triandrous, but ours usually have 5 or 6 

 stamens. The older trees attain a height of 9-12 meters and the 

 bark resembles that of S. nigra, but the large lanceolate leaves, 

 whitish below, and the reddish young shoots give it an entirely dif- 

 ferent aspect. From form of leaf and color of twig it is well-named 

 the ' ' Peach -leaved Willow. ' ' Its twigs are somewhat tough at the 

 base while those of S. nigra disarticulate very readily. Professor 

 Sargent in " Forest Trees of Nor. Amer.,' 1 ' 1 {Census Rep., Vol. IX. 

 1880,) gives the eastern limits of distribution, as Wayne Co., N. Y. 

 We have observed it in stations 30 or 40 miles east of this range. 



Low grounds, streams and shores; abundant. Flowers May 10-30. 



Case. Cr. north of Eddy Pond. Six Mile Cr. Neguaena valley, — 

 abund. Cayuga Lake, whole length. Cayuga Marshes. Montezuma 

 Marshes. Near Waterloo. (Watkins, Seneca L. ) Venice, west of 

 Cascade. Scarce near Freeville and Cortland. 



839. S. lucida, Muhl. Shining Willow. (H. and C.) 

 Streams and shores ; frequent. May 20-30. 



Case. Cr. below Eddy Pond. Frequent along the low points of 

 Cayuga Lake. In Ca)-uga Marshes. Near Freeville, McLean, 

 Beaver Cr. Dryden Lake valley, Bear Swamp, and elsewhere. 



840. S. lucida, Muhl. var. with beautiful shining, coriaceous, 



very finely serrate leaves, larger, light-brown pods, and flowers and 

 fruits very much later than in the type, occurs in the Round- 

 Marshes. I have also collected it in Bergen Swamp, N. Y., from
