Bri/um.] MUSCI-ACROCARPI-PERISTOMI. 57
B. Internal peristome formed of a membrane more or less divided
into lacinicE.
27. BrYUM. Linn. Thread-Moss.
Seta terminal. Peristome double : the outer of 16 teeth; the
inner of a membrane cut into 16 equal segments, with filiform
processes frequently placed between them. Calyptra dimidiate.
(Muse. Brit. t. 3.)—An ancient name of Dioscorides, given by
Dillenius to this Genus and its affinities.
1. Capsules sulcated. (Milium, Brid. not Sm.)
1. B. androcj;/num, Hedw. (narrow-leaved Thread-Moss);
stems nearly simple, leaves lanceolate serrated their margins
recurved, capsule nearly erect cylindrical sulcated, lid conical.

In woods and on banks. Fr. ? very rare.— Surface of the leaf
papillose. The colour pale green. The male flowers, as Hedwig calls
them, form a granular head, terminating an elongated and almost leafless
portion of the stem : but these assuredly are gemmae and quite different
from the anthers (so called) in other mosses, which Mr. Wilson finds
mixed with the pistils. Hence the name is peculiarly applicable,
though Linnaeus could not have understood it in this sense.
2. B. palustre, S\v. (Marsh Thread-Moss); stems much
branched, leaves lanceolate obtuse entire their margins involute,
capsule ovate oblique sulcated, lid conical. Swart:. Muse.

discoid. These are besides powdery or granulated heads on elongated
naked Btems -.!• branches, similar to those of the preceding species: but
here, they are looked upon as gemnus. The inner peristome o£ both
