Needham. 
D. canadense (L.) DC. Dry soil, common. 
D. canescens (L.) DC. Dry open woods, rare; Ipswich, Natick, 
Winchester, W. Cambridge, Revere, Waltham; roadside, Arlington, 
August, 1853 and 1869 (Wm. Boott), according to Dame & Collins,

D. Dillenii Darl. Dry open woods; numerous stations in Middle- 
sex and Norfolk counties. Not reported from Suffolk and Plymouth 
counties, and only collected from Georgetown and Wenham in Essex 
County. 
D. grandiflorum (Walt.) DC. Rich woods, frequent. 
[D. glabellum (Michx.) DC. Reported from “ Mass.” in Gray’s 
Manual, 7th ed. Investigation at the Gray Herbarium shows that 
this report is based on a specimen collected by J. W. B. (John Wright 
Boott) in 1832. The label is in Francis Boott’s writing. The sheet 
went to the Herb. Benthamianum in 1854, thence to the Gray Her- 
barium. On the herbarium sheet some unknown hand, evidently 
English, has written in pencil “ Boston, U. S. A.” There is therefore 
no reliable information as to where this plant of John Wright Boott’s 
was collected.]

ently rare in Essex county. 
D. nudiflorum (L.) DC. Dry open woods, common.
