as at outlying points and was met with in such uninhabited quarters 

 as the "Woods" and east of Hummock Pond. It is well estab- 

 lished on and below the bluff at 'Sconset, where groups of vigorous 

 young trees were observed in 1904 and 1906, the larger being ten 

 feet or more in height. In trees of this age the bark of the trunk 

 and branches is smooth and pale greenish-gray, the younger twigs 

 pale green and yellowish. That the tree was early planted in 

 Nantucket is shown by some old trees in the outskirts of the town, 

 in which the trunks are seamed and furrowed and gray with 

 lichens. Not observed in flower or in fruit. The foliage of the

as a hybrid, and as such has maintained itself and increased its 

 foothold, it is of particular interest to find that its parent species, 

 Salix cincrea L. and Salix vwimalts L., are also present on the 

 island. A single tree of each was met with at points about six 

 miles apart on opposite sides of the island. The detailed record 

 of each follows.

A single tree grows by a pond in a low field on the western 

 side of the town. The tree is a very old one and is of large size 

 for the species, the gnarled and sloping trunk thickly clothed with 

 young shoots. It stands close to the rear yard of an old dwelling, 

 where it may be supposed to have been originally planted, and it is 

 referred to here only on account of its interest as one of the alleged 

 parents of Salix Smithiana. 



* Salix cinerea L. 



A single thriving shrub of several stout stems about ten feet 

 high on the border of Tom Never's Swamp, growing with Salix Beb- 

 hiana and Salix petiolaris. Bark of the stems smooth, and pale 

 yellowish-gray. This shrub was first observed Sept 15, 1907; 

 on June 13, 1908, it bore many mature fertile catkins. Specimens 

 collected agree closely with a sheet of Seringe's Swiss Willows 

 in the herbarium of the New York Botanical Garden labeled as 

 folio
