1910] Flora of the Boston District,— VII 95 
REPORTS ON THE FLORA OF THE BOSTON 
DISTRICT,— VII. 
IN preparing this list, the committee has continued the practice of 
giving records of existing specimens collected. more than fifty. vears 
ago, that is, before 1860. There are, however, numerous specimens 
collected by William Oakes, in and around Ipswich for the most part, 
without any dates. ‘These have not been quoted, except where the 
plants are very rare. Of course they were all collected before July 31, 
1848, when William Oakes met his tragic death. Another old-time 
collector who noted few dates was €. J. Sprague. 
Where lists of towns are given for the rarer plants, the alphabetical 
order has been changed to the geographical order of north to south and 
east to west. We feel that this will be more satisfactory, and give a 
much better idea of plant distribution. ‘The committee has worked 
from rather limited data in regard to some of the species, and if any 
readers of Ruopora can add anything to the facts stated here, the 
knowledge will be gladly received. 
JUNCACEAE. 
JUNCUS. 
J. acuminatus Michx. Wet sandy and muddy places; common 
throughout. Collected by John A. Lowell in Danvers, July 1, 1846, 
and in Beverly, August, 1849, and by Wm. Boott in Milton, Aug. 29, 
1833. 
J. articulatus L. Wet soil; Stoneham, Medford, Cambridge, 
Mattapan [Dorchester]. There are various printed records for this 
species, but since the variety has been segregated, it is impossible to 
know just what is meant by them. The type is apparently rare in our 
territory. 
J. articulatus L., var. obtusatus Engelm. Wet soil; Lowell, Stone- 
ham, Malden, Milton and Blue Hill Reservation. Collected by 
Wm. Boott in ‘‘wet field near Tavern, Spot Pond, Stoneham, July 11, 
1853,” and at Edgeworth [Malden], July 19, 1853. 
J. balticus Willd., var. littoralis Engelm. Moist sand, mostly 
brackish, all along the coast.
