208 Rhodora [DECEMBER 
PUCCINELLIA DISTANS (L.) Parl., var. TENUIS (Uechtr.) Fernald € 
Weatherby, Ruopora, xviii. 12 (1916). Saline clay about the salt 
sheds, south of Liverpool, Syracuse, Onondaga County. 
An addition to the list of semi-halophytic plants of the Onondaga 
region. The coarser typical form of P. distans has already been 
recorded from there (Fernald € Weatherby, l. c.). 
ELyMus ROBUSTUS Scrib. € Sm., var. vestirus Wiegand, RHODORA, 
xx. 90 (1918). . Sand dunes overlying Silurian shales and schists by 
Lake Ontario, Selkirk, Oswego County; damp ledges of Trenton lime- 
stone, bank of Black River, Dexter, Jefferson County. 
ELEOCHARIS OLIVACEA Torr. Quaking peaty margin of Mud 
Pond, Oswego, Oswego County. 
SCIRPUS SUBTERMINALIS Torr. Quaking peaty margin of Mud 
Pond; Oswego, Oswego County. 
S. HETEROCHAETUS Chase. Deadwater at mouth of Salmon 
River, flowing over Silurian shales and schists, Selkirk, Oswego 
County. i 
Beautifully distinct and forming extensive colonies at the margin 
of the deadwater, where it is associated with S. fluviatilis (Torr.) 
Gray and Typha angustifolia, var. longispicata Peck. 
CAREX TRISPERMA Dew., var. BiLLINGsi Knight. Knolls in peat 
bog by Mud Pond, Oswego, Oswego County. 
C. LONGIROSTRIS Torr. Rich woods on Silurian limestone near 
Natural Bridge, Limerick, Jefferson County. 
Juncus BALTICUS Willd., var. LITTORALIS Engelm., forma dissiti- 
florus Engelm. in herb., caulibus 0.4-1.1 m. altis; inflorescentiis dis- 
sitifloris diffusis 0.4-1.5 dm. longis. 
Culms 0.4-1.1 m. high: inflorescences remotely flowered, diffuse, 
0.4-1.5 dm. long. 
A very characteristic form of the American var. littoralis designated 
by Engelmann in the Gray Herbarium but apparently not published 
by him. The form in its most extreme development is very 
typical of the sands of the Great Lakes, but perfectly characteristic 
var. littoralis, with less diffuse inflorescences and somewhat approxi- 
mate flowers, also occurs there; conversely, although the common 
plant of the Atlantic coast is typical var. littoralis, the forma dissiti- 
florus is occasionally collected near the sea. The following are 
representative of forma dissitiflorus.
