* Comparatively little has been published about the occurrence of this rather 

 unique plant on Cape Cod. G. B. Emerson, in his classic report on the trees 

 and shrubs of Massachusetts (1846), had no record of it from east of Plymouth, 

 but Thoreau found it about that time in Provincetown and near Highland 

 Light in Truro. J. H. Redfield, in summing up the known distribution of the 

 species in 1884 (Bull. Torrey Bot. Club 11: 99), stated that Dr. Watson had 

 seen it near Truro and one of the coves of Buzzard Bay. Dr. Hollick reported 

 it from Provincetown in 1902 in the paper cited, and Mr. Collins (Rhodora 

 11: 128. 1909) mentioned it as frequent and showy in spring in Eastham. 

 Mr. Knowlton showed me a considerable quantity of it beside the main road 

 in the northern edge of Eastham.
