THE MOSSES OF THE AZORES. 55 
laxis magnis, quadrangulis, inanibus, caeteris e cellulis parvis, incras- 
satis, stereidis intermixtis formatis. Caetera ignota.— Pl. 2.—a, entire 
plant, nat. size; b,b, b, leaves X 14; ¢, basal areolation of a leaf < 130; 
d, marginal areolation in the middle of a leaf X 260; e, e, leaf point 
>< 130; J, portion of a transverse section of a leaf < 260. 
Closely allied to C. Boryanus Besch. from Reunion Island, which has 
exactly the same structure of the costa; but C. setaceus has the stems and 
branches more slender and the leaves less crowded, with a much longer 
and thinner subula.

Mitten’s views, we consider this as a synonym of 
C. introflexus Brid. 
The moss from San Miguel is a very peculiar form, with long, slender 
innovations, suddenly clavate at apex. Several female flowers are found 
in the terminal bunch of the comal leaves, which are rather abruptly 
constricted to the point and with rather well defined and often excavate 
auricles.

The plant from Sta. Maria is a small form, with very narrow leaves, 
much resembling L.molle C. Miull., from Madagascar.
