120 Rhodora [JUNE 
this species in New England, as it has not been reported from Rhode 
Island or Connecticut. 
Lycopodium inundatum, L. Sandy shore of Lead Mine Pond, 
Sturbridge, July 31, 1898; also in a wet sandy place in another part 
of the same town, August 28, 1898. 
Jsoefes echinospora, var. Braunii, Engelm. During last July and 
August I found this interesting and comparatively little-known plant 
in Worcester County in a number of stations and under a variety of 
conditions. I have seen it in muddy, sandy, and rocky bottoms of 
brooks and rivers, in Southbridge, Sturbridge, Dudley, and Brookfield, 
at altitudes ranging from 395 feet in the Quinebaug River in Dudley 
to 640 feet in Cohasse Brook in Southbridge. Some of the specimens 
observed grew above low-water mark, and were left high and dry by 
the natural subsidence of the water in dry weather. This plant has 
been previously reported in Worcester County only from Lake Quin- 
sigamond, by Dr. Stone. 
Sagittaria graminea, Mx. In muddy places or under water, 
Dudley, Southbridge, and Brookfield. I found the flowering, leaf- 
bearing form near the Quinebaug River in Dudley, July 3o, but else- 
where I have seen only the submersed sterile form with phyllodia. 
On September 4, in company with Dr. Stone, I found this form on 
the sandy bottom of Quaboag Lake, about three feet below the surface. 
How the plant perpetuates itself in such a situation is an interesting 
question. 
Panicum xanthophysum, Gray. Dry open woods, etc. South- 
bridge. This plant is also unknown in Rhode Island and Connecti. 
cut, and has been reported in Massachusetts only from Princeton and 
Framingham. : 
Oryzopsis asperifolia, Mx. In woods, Oxford, Southbridge, Stur- 
bridge, and Brookfield. Previously known in Worcester County only 
on Mount Wachusett. 
Oryzopsis melanocarpa, Muhl. Rocky woods, Sturbridge, July 23 
(altitude 920 feet). Previously reported from Princeton. 
Muhlenbergia Willdenovii, Trin. Rich woods, Dudley, August 27. 
Muhlenbergia diffusa, Schreber. Dry fields, Southbridge, Au- 
gust 31. 
Glyceria acutiflora, Torr. Muddy ditch in meadow, Southbridge, 
June 23 (altitude 660 feet).
