A gemmiparous pterigynandrum 
by J. A. WueznoN F. L. $. 
An interesting moss was recently sent to me by Sir James” 
_ Stirling, labelled Pterigynandrum filiforme (?). It was apparently 
a somewhat slender state of that species, with a peculiar facies 
_ due to its elongated branches, and delicate colouring-pale green 
on the surface of the tufts, light reddish brown in their interior. 
On microscopical examination the axils of the leaves were 
= found to be filled with gemmæ, large numbers of which became 
_ detached when the stems were wetted. So far as I have been 
_ able te discover, gemmæ have not been previously observed on 
this moss ; and it may therefore be desirable now to record 
their occurrence. à 
 Whether Sir James Stirling’s plant should be regarded as speci 
fically distinct from the ordinary form of P. filiforme is perhap 
open to discussion. The specimens collected are without capsules, 
_ and beyond the gemmæ they present only minor differences 
_ from the type. Nevertheless gemmæ are sufficiently rare in the 
_ generality of mosses, as to stamp those known to produce them 
with a distinct individuality; and M. Dixon, in the € Students
