﻿44 BiCKNELL : Ferns and flowering plants of Nantucket 



from Nantucket, the northern limit of its then known range. 

 Mrs. Owen remarks of this in her catalogue that the Nantucket 

 locality is unknown and that the plant had never been "found by 

 collectors of the present day." Quite possibly the station east 

 of the town had been discovered by some botanist over half a 

 century ago and was the basis of Dr. Gray's record. 

 KoELLiA virginiana (L.) MacM. 



Frequent in Squam, at scattered stations, extending towards 

 Pocomo and south to Sachacha Pond, also sparingly near Siascon- 

 set. Nearly in bloom July 8, 1912; still in flower September 16, 

 1899; no flowers left September 21, 1907. 

 Koellia mutica (Michx.) Britton. 



Frequent at the eastern end of the island, in Squam, and in 

 "The Woods" on the western side; it is also found near the middle 

 of the island about the head of Miacomet Pond. First flowers 

 July 8, 1 9 12; in full flower in August and as late as the middle 

 of September. 



The Pycnanthemum incanum Michx. of Mrs. Owen's catalogue 

 doubtless refers to this species. 

 * KoELLiA verticillata (Michx.) Kuntze. 



Found sparingly at several stations in Squam, near Wauwinet 

 growing with Koellia virginiana. First flowers July 8, 1912, 

 The Nantucket plant is distinctively Koellia verticillata as set apart 

 from the more southern Koellia Torreyi (Benth.) Kuntze. Its 

 lanceolate leaves vary from entire to serrate with few but distinct 

 cartilaginous-tipped teeth, and the uppermost leaves, with the 

 floral bracts, are canescent. It seems to be always closely asso- 

 ciated in growth with K. virginiana in a part of the island in- 

 habited also by K. mutica, and its aspect and characters appear 

 to be so obviously intermediate between these two plants, tending 

 now towards the one and now towards the other, that its status 

 as an independent. species, at least on Nantucket, assuredly becomes 

 open to question. 

 ♦Thymus Serpyllum L. 



Collected on Nantucket in August, 1906, by Miss Mina K. 

 Goddard. A specimen in flower and fruit was kindly sent to me 

 for examination by Mrs. Flynn.
