Bicknell: Ferns and flowering plants of Nantucket 27 



oak remains to be determined. 



Q 



prinoides or it may be a distinct although vzvy closely related 

 species. 



Note. — Several species of introduced oaks, some appearing 

 like native trees, grow in the long-neglected lot, near the present 

 Benjamin Coffin farm west of the town, which has already been 

 referred to as a station for the European birches, Betiila pubescens 

 and Betiila pendida. These oaks are the following, there being 

 from one to several small trees of each species : Querctts bkolor 

 Willd. ; Quercus rubra L. ; Quercns paliistris Muench. ; Querciis 

 Robur L- 



ULMACEAE 



* UlMUS AMERICANA L. 



A few small scattered trees have sprung up among the pines 

 on the Surfside road, where they appear to be wholly spontaneous. 

 Two trees estimated to be about thirty feet in height grow to- 

 gether on the edge of Trot's Swamp on the north side. This part 

 of the island is now quite uninhabited and these trees appear like 

 part of the native vegetation, but they are not far from a long- 

 abandoned farm, and some trees of Popuhts candicans near them, 

 of considerable size, are unmistakable evidence of man's handiwork 

 in generations gone. All of these elms are the form with pubes- 

 cent branchlets with the leaves very scabrous on the upper surface. 



Elms were early planted in the town, where they have thriven 

 well and become a very beautiful feature of some of the main 

 streets. 



Note. — Some small trees and shoots of the European elm 

 {Ulmtis campestris L.) are found along the road to Surfside, be- 

 yond the outskirts of the town, but they are only sparingly spon- 

 taneous about trees that must have been originally planted. 



MORACEAE 



* HUMULUS LUPULUS L. 



Along an old roadside fence and in an adjoining field west of 

 the town ; also on Crooked Lane, and at several places near culti- 

 vated ground, where it is less clearly spontaneous. First noticed 

 in a wild state in 1906.
