angles of the cells, or in the middle . . . Ec Dus Ea

PTERIGYNANDRUM FILIFORME (Timm) Hedw. According to Dr. 
Grout! this moss is not uncommon, but it had apparently been 
overlooked in Connecticut until the fall of 1909 when the writer 
happened to discover a few sterile, depauperate specimens growing on 
a dry ledge in the town of Bethany. In its general aspect, as remarked 
by Grout, P. filiforme resembles some of the species of Leskea. The 
plants ordinarily have, however, a marked vellowish cast, the branches 
are usually numerous and are all curved at the tip, pointing in the 
same direction, while frequently slender flagelliform branches are 
developed. The leaf cells are considerably longer than in Leskea, 
except on the flagelliform branches where they are often quite short. 
POGONATUM BRACHYPHYLLUM (Michx.) Beauv. This typically 
southern seaboard species has been collected in most of the states 
bordering on the coast from ‘Texas to New Jersey, but heretofore it 
has not been reported from New England. During the past fall the 
writer had the good fortune to find it in the town of Branford. The 
plants grew on earth underneath a large bowlder near the shore of 
Long Island Sound, the entire colony being restricted to an area less 
than five feet in length by one in width. A search of the adjacent 
shore line for several miles has as yet failed to reveal further traces of 
this interesting form. The plants first collected bore either immature 
or old sporophytes, but a recent collection shows that the spores are 
ripe in this latitude about the middle of April. P. brachyphyllum 
resembles somewhat the common P. tenue (Menz.) E. G. Britton, 
but it is readily distinguished by its blunt, entire leaves. 
DREPANOCLADUS ADUNCUS (L.) Warnst. 
All specimens listed in ** The Bryophytes of Connecticut" as Drepan- 
ocladus aduncus (L.) Warnst. (p. 168) must be referred to D. sub- 
aduncus Warnst. (p. 168). D. aduncus has not yet been found 
Connecticut, although it is probable that it occurs in the more northern,
