Dear All, May 27, 2010
While reviewing some 1975 plant records recently I came across a long
forgotten remark re Buxbaumia aphylla (Flatiron Moss, for those who have
heard of flatirons).
The remark being-- "Of 15 setae, all but 4 had capsules missing. Does
something eat (these) capsules ?"
If capsules were entirely absent, in a stand of this moss, then one
would never notice the short setae. And I recall having noticed this plant
only twice in 60 years.
John Erskine (An introductory moss flora of NS) observed-- They
"...appear and disappear for years. In 1946-48 I found four stations, and in
the nineteen years since I have not seen any."
So the question is renewed. Does this moss develop capsules
infrequently, does something frequently eat them before they are noticed or
are they commonly present but overlooked ?
