204 Rhodora [NOVEMBER 
Of the seven species and two varieties of 4nfennaría now known in 
Massachusetts (see RHODORA, 1: 160), I have thus far distinguished 
six in Worcester County, as follows : — 
A, Parlinii, Fernald. This handsome species is usually found in 
partially shaded situations, often on a sloping bank by the roadside, or 
occasionaly in moist meadows, not common, Southbridge, May 7 
(in flower) ; Sturbridge, May 28; Warren, May 30; Leicester and 
Charlton, June 4 (akenes beginning to fall). Extends southward into 
Connecticut. Only pistillate specimens found. 
A. Canadensis, Greene. Gravelly shore of Lead Mine Pond, Stur- 
bridge, May 28 (pistillate only) ; also seen without flowers along un- 
frequented roads or in dry open places, Charlton, August 13 ; Sturbridge, 
September 4 ; Southbridge, September ro. 
A. plantaginea, R. Br. Dry fields, woods, roadsides, etc., very 
common and variable. (Staminate and pistillate.) 
A. plantaginea, var. petiolata, Fernald. Fields and roadsides, South- 
bridge, often with the type. (Staminate and pistillate.) 
A. neodioica, Greene. In dry fields, woods, etc., especially among 
rocks. Pistillate plant quite common. Staminate plants found only 
once, in a cluster of about twenty individuals or flowering stems, 
spreading over an area of one or two square feet, by a roadside in 
Southbridge, with some pistillate plants in close proximity. This is the 
first and only known station for staminate A. neodíoica in New England. 
A. neglecta, Greene. Dry pastures, roadsides, or even in sphagnous 
wet meadows, common. The wet meadow form usually has larger 
leaves (sometimes 5.5 cm. long), smooth or nearly so above, and fewer 
stolons. 
Further study of this interesting genus will no doubt reveal other 
species in the county than those listed above. 
The following plants of my previous article have been collected this 
year in additional stations : — 
Spirodela polyrrhiza. Southbridge, August 13; Brookfield, August 
20. 
Glyceria elongata. Royalston, July 2. 
Glyceria pallida. Southbridge, June 27. 
Panicum proliferum. Shore of Quaboag Lake, Brookfield, August 20. 
Carex laxiculmis. Dudley, July 30. 
Cladium mariscoides. Quaboag River marshes, Brookfield, June 18. 
Lleocharis Robbinsti. Shallow water, Douglas, August 6.
