cluster of small shrubs but is in reality from a single root, the 

 lower branches at first widely spreading on and below the surface 

 of the ground. ' 



Myrica carolinensis Mill. 



Everywhere an exceedingly common shrub, much dwarfed in 

 dry open places, in low thickets becoming eight feet high. 



COMPTONIA PEREGRINA (L.) Coultcr. 



Common over the plains and in the oak barrens, mainly on the 

 southern and eastern sides of the island. ' 



JUGLANDACEAE 

 HicoRiA ALBA (L.) Britton. 



Frequent in thickets, mainly in the northeast quarter of the 

 island: Shawkemo ; Quaise; Polpis ; Pocomo ; Squam ; barrens 

 west of Sankaty. Sometimes fruiting well when not over six feet 

 high. No trees seen over fifteen feet in height. In full flower 

 June 1 1 ; fruit nearly full size the second week of September. 



HicoRiA MiCROCARPA (Nutt.) Britton. 



South of Wauwinet, in a dense thicket, Sept. 2, 1 904 — a 

 single stout tree perhaps ten feet high with wide-spreading 

 branches, the lowermost resting on the ground. Fruit abundant, 

 definitely compressed, suborbicular in outline and mostly broader 

 than long, the smaller, when dried, 18 mm. long and wide and 15 

 mm. thick, the larger 22 mm. long, 25 mm. wide, and 20 mm. 

 thick. The bark of this tree was very pale and smooth like that 

 of a beech, which seems to be a characteristic common to the 

 three hickories native to Nantucket. 



A single tree about seven feet high was found in a thicket in 

 Pocomo, Sept. 21, 1907. 



HicoRiA GLABRA (Mill.) Britton. 



Apparently^ rare, and certainly much less frequent than the 

 mockernut. Found only in Shawkemo, and in Pocomo, fruiting 

 rather sparingly. Fruit full size Sept. 11-21, 1907, obovoid- 

 oblong or pyriform, the largest 28 mm. long, 24 mm. wide, 21 

 mm. thick. On June 9, 1908, it was much less advanced in 

 foliage than was Hicoria alba growing with it and no aments
