MEGACEROS DENTICULATUS (Lehmann) Stephani
Presumably? leg. Raoul, Nr* 6it, Akaroa, Bank's Peninsula,
New Zealand.
At first sight it looks as if this material is from the
same collection as the type material of Anthoceros den-
ticulatus Lehmann, of unknown detailed provenance. Red,
white, and blue textile fibers (see pencilled arrows and
patch of isolated fibers), possibly from the sweater of the
collector, are caught between the thalli; similar blue
fibers are associated with the type fragment. On detailed
comparison I rejected this possibility for a variety of
reasons, including state of convolution of the unistratose
wing of the thallus, behavior of the chloroplasts on soaking,
the fact that in this Mitten material it was not possible to
prove that the plant is monoecious, and particle size of
adhering silica grains. (Two other Raoul homwort collection^
are extant, Nr. 62 -Phaeoceros sp.- at Kew, where I have
been unable to locate any more of this Nr. 61*, and Nr. 61
at Paris -Megaceros leptohymenius.)
The present material exhibits extensive leaf miner damage.
A pupa was found imbedded in the thallus tissue at the pointj
marked "A" by me. I removed it and sent it to Prof. E.M.
Hering, Berlin, with whom I am cooperating on a liverwort
and hornwort leaf miner study. This specimen, determined by !
him as Liriomyza sp. (Diptera, Agromyzidae), is in the
attached pocket.
