1917] Additions to the Flora of Connecticut 109 
* LEERSIA ORYZOIDES (L.) Sw., forma CLANDESTINA Eames. Ruo- 
DORA, xviii. 239 (1916). Rare. Stratford (Eames, |. ¢.).  Distin- 
guished from the typical form by having the terminal as well as the 
lateral panicles included in the sheaths. 
HIEROoCHLOË oporata (L.) Wahlenb. A form with very large 
spreading panicles occurs at Fairfield (Eames). 
* Mitium errusum L. Millet Grass. Rare. Rich, rocky woods, 
Hartland (Bissell & Weatherby). 
Oryzopsis PUNGENS (Torr.) Hitche. Suffield and Simsbury 
(Weatherby), Morris (J. P. Brace about 1820; specimen in Herb. 
Williams College. Am. Journ. Sci. Ser. 1, iv. 73; Ropora, xvi. 90). 
In the Catalogue not reported from west of the Connecticut River. 
In the Catalogue the ranges of three species of Muhlenbergia of the 
mexicana group were necessarily left somewhat indefinite because of 
lack of data. It is now possible to make a more definite statement, as 
follows :— 
-MUHLENBERGIA SYLVATICA Torr. Occasional. Woods, borders of 
thickets and banks of streams. 
M. routosa (R. & S.) Trin. Open bogs, wet woods, or rarely in 
drier ground. Frequent in the northern part of the state, becoming 
occasional near the coast. 
The awned form has been collected at Guilford (W. R. Dudley, 
1872; specimen in Herb. Yale University). 
M. mexicana (L.) Trin. Fields, dooryards, roadsides and waste 
places, preferring moist, rich soil: Scotland (Weatherby), Litchfield 
(J. P. Brace about 1820; specimen in Herb. Williams College: R#o- 
DORA, xvi. 90), New Milford (Eames) and frequent or locally common 
in the central and southern parts of the state. Not reported from 
Tolland Co. 
The awned form occurs with the typical form, but less commonly. 
These three species, though offering, as defined by Prof. Scribner, 
a much more natural classification than the old one based on the 
presence or absence of the awn, are closely related, variable and not 
always easy to distinguish clearly. As between M. mexicana and the 
other two, a serviceable and constant character is found in the culm, 
which in the former, is glabrous throughout and in the two latter, 
minutely puberulent below the nodes.— C. A. WEATHERBY. 
M. CAPILLARIS (Lam.) Trin. Cheshire (A. E. Blewitt). Otherwise 
known only from New Haven.
