OTHER MOSSES NEW TO CONNECTICUT. 
DicraNnum BonsEANI De Not. (D. palustre La Pyl.). Growing 
mixed with D. Drummondii in a spruce bog, altitude 120 m., New 
Fairfield (G. E. N., 1912). Determination verified by Mr. R. S. 
Williams. The Connecticut specimens seem to agree well with the 
typical form of the species. The leaves are bronze green in color, 
slightly secund, and decidedly undulate. They bear a marked 
resemblance to leaves of D. undulatum, but the serration both along 
the margin and at the back of the midrib is much less pronounced here 
than there. Fruit matures in late summer. D. Bonjeani has been 
accredited to Maine,! New Hampshire,? Vermont,’ and Massachusetts.* 
It is found throughout arctic North America, Canada, and the north- 
ern United States, extending southward along the mountains to 
Georgia, Colorado, and California; Europe, Asia. 
BARBULA CONVOLUTA Hedw., var. COMMUTATA (Jur.) Husn. Seri- 
cite schist bluffs bordering the Connecticut River, altitude 30 m., 
Portland (G. E. N., 1909). Determined by Mr. Williams. When 
in fruit B. convoluta is readily recognized by its long, convolute, sheath- 
ing perichaetial leaves Sterile plants might be mistaken for B. un- 
guiculata. It differs, however, in the character of the leaf margin 
which in that species is revolute nearly to the apex while here it is 
plane except near the base; also by the fact that in the present species 
the midrib, instead of being excurrent, vanishes in or below the apex. 
The variety is somewhat larger than the typical form of the species and 
has longer, firmer, slightly recurved leaves. Fruit matures in spring. B. 
convoluta is reported from Vermont * and Massachusetts 5; it is widely 
scattered through temperate North America; Europe, Asia, Africa.
