THE WILLOWS OF OHIO. 281 



The blue willow, Salix alba coerulea, has not yet been recog- 

 nized in Ohio. Indeed there are some willow students of high 

 authority who do not distinguish it at all in this country whatever 

 may be its status in the old world. 



As hinted above Salix alba hybridises with Salix fragilis 

 though not so frequently as might be supposed. It al 

 with S. lucida as described under that species. 



Salix babylonica L. Weeping Willow. 



The Weeping Willow -rows into a large graceful tree 20 25 

 m. tall, easily recognized by its very long drooping twigs, which 

 have a habit peculiar to themselves of -ending out numer 

 short branches at a very acute angle with the mam stem. Leaves 

 commonly rather small, 7-10 cm. long, about 1 cm. broad, nar- 

 rowly lanceolate, long acuminate and often fa! 1 the tip, 

 narrowed to the base, sharply serrate, glabrous unless very 

 young, greenish glaucous or at least paler beneath, petiole sh 

 stipules apparently absent; primary veins forming regular acute 

 loops which run together into a more or less straight marginal" 

 this together with the very fine reticulations caused by the rela- 

 tive prominence of the tertiaries often gives the leaf a more or 

 less cli semblance to that of S. nigra, which, however, is 

 newer glaucous as in the present species. Aments on rather sh< >rt 



leaved peduncles, rather dense, not more than '.', cm, long. 

 capsule short conic, glabrous, green, all but sessile, style short. 



h is a remarkable fact that the staminate plant of this species 

 is unknown in America. It i etimes that it does not 



ur at all and it i^ sufficiently rare to warrant such an ion 



but yet in the national herbarium is what 1 believe to be a gen- 

 uim en of tin- staminate flowers. It was collected by
