1922] Fernald—Notes on the Flora of Nova Scotia 179 
described by Roth, might be discussed, but enough has already been 
emphasized to indicate that Roth's detailed description of O. tetragona 
departs in very many points from O. hybrida and that those who 
wish to throw out Michaux's specific name must find an earlier name 
which is more clearly synonymous with it than is O. tetragona Roth. 
MYRIOPHYLLUM HUMILE (Raf.) Morong. YanMwovrH Co.: Vaughan 
(Tusket) Lake. LUNENBURG Co.: Feindel’s Lake, west of Bridge- 
water; Rhodeniser Lake. Hants Co.: Uniacke Lake. 
M. TENELLUM Bigel. The tremendous veriation in the stat ire of 
this species is illustrated by our collections. At the gravelly margin 
of Uniacke Lake (Hants) the plant was flowering when 2.5-5 cm. 
high; but in a peaty cove of Little Meteghan Lake the coarse stems 
reached a height of 5.5 dm. 
PROSERPINACA PALUSTRIS L. At various stations from Yarmouth 
Co. to Annapolis and Lunenburg Cos.: in the latter region sometimes 
reaching remarkable development: 0.5 m. high, with emersed leaves 
up to 8.5 em. long and 1.3 em. broad. 
P. PECTINATA Lam. Additional stations, for YARMOUTH Co: wet 
sevannahs bordering Goven and Kegeshook Lakes and South Branch 
by Tusket River, Quinan. LUNENBURG Co.: sphagnous swale west 
of Italy Cross; sandy and gravelly beach of Blystner Lake; peaty 
bottom of dried-out mill-pond north of Blockhouse. 
** HYDROCOTYLE UMBELLATA L. YARMOUTH Co.: wet sandy and 
gravelly margin of St. John (Wilson's) Lake; first time east of Massa- 
chusetts. Very rare and local and appearing like a waif washed down 
from some as yet undiscovered station farther up the valley of the 
Tusket. 
H. americana L. Frequent eastward at least to Annapolis and 
Lunenburg Cos. 
* Aethusa Cynapium L. Waste ground in barn-yard, Shelburne. 
CORNUS STOLONIFERA Michx. Westward to Annapolis Co. 
PYROLA CHLORANTHA Sw. At various stations in Digby, Annapolis 
and Hants Cos. Var. paucifolia Fernald seems hardly worth main- 
taining. 
P. ROTUNDIFOLIA L., var. ARENARIA Mert. & Koch. Additional 
stations eastward to Hants Co.
