which place Mr. Bebb has received it. as well as sparingly from X. 

 J., Ohio, and Mich. Flowers from June 10-30 and matures fruits 

 slowly, the writer obtaining pods still in excellent condition, Sept. 

 9. 1880. 

 841. S. fragilis, L. Brittle Willow. (H.) 



Form, (cultivated) ; "near true S. fragilis ," according to Mr. 

 Bebb. May 10-20. 



Planted near the south, barn on Univ. Farm. Near Hibbards Cor- 

 ners. Near Fleming S. H. King's Ferry Sta. At water's Sta., etc. 

 This form is not pure S. fragilis, L. but probably the result of a 

 crossing several times over with already mixed forms of.S". a/da, I., 

 in which result S. fragilis, L. decidedly predominates. It is exten- 

 sively propagated from cuttings and planted as a wind-break — pas- 

 sing under the name of " Black Willow." Specimens which cannot 

 be clearly distinguished from the cultivated are found on Fall Cr. 

 Marsh, on Myers Pt. and elsewhere growing spontaneously. 



S42. S. fragilis, L,. X S. alba, L. 



Spontaneous forms with yellowish twigs from Negundo Woods- 

 and by the R. R. near the woods ; also by the R. R. east of Free- 

 ville and east of McLean ; Cayuga Lake shore at Taughaunock, on 

 Myer's Point, Lockw T oods Flats and elsewhere, are here included, 

 and are pretty clearly hybrids between the above so-called species, 

 having characteristic traces of their flowers and leaves. 



843. * S. alba, L. var. vitEU.ina, Koch. — (? form. Probably a hy- 

 brid derived from the true var. vilellina, Koch, and S. fragilis, L. Its 

 branchlets are usually yellow.) Yellow Willow. (H. and C.) 



Planted to protect creek and R. R. embankments. May 10-20. 



Willow Pond. Willow Ave. Ithaca along Six Mile Creek, and 

 elsewhere. Also frequently wild along streams and shores. Always 

 pistillate. The hybrids mentioned above, between S. fragilis and 

 5". alba are no doubt derived on the 5". alba side from the present 

 form, which has been long in cultivation ; but the history and ori- 

 gin of the American hybrids, between these two species, are admit- 

 ted by the best authorities to be involved in the greatest obscurity. 



844. S. alba, L. var. vitellina, Koch, X S. lucida, Muhl, (probably.) 

 Neguaena Creek ; marshes north of Ithaca, along the Cayuga So. 



R. R. ; and Cayuga L. to Union Springs ; not uncommon. May 10-20- 

 An arborescent form of luxuriant growth, sometimes its trunk and 

 branches are quite yellow, sometimes gray-green. Its wood is 

 everywhere brittle. Both staminate and pistillate plants occur ; and 

 when in flower, the former are as striking as the best marked spec- 

 ies of willow. Catkins are very abundant, bright yellow, 6-7 cm. 

 long, and fill the air with their peculiar balsamic fragrance. The 

 stamens, — usually 4-5 in each flower, — leaves and stipules suggest 

 -S". lucida, while the long catkins, color of twigs in many, and the 

 habit of the plant, are like S. a/ba-viie/lina. (Also grows in 

 Wayne Co., N. Y. , E. L. Hankenson.)

leaves and young twigs ; and S. alba, L. var. vitellina, Koch, are
