l.c. (1942):5, Lloyd said literally:
"
I myself included it (i.e. _Roridula_) among the carnivores in an
account published in 1933. Since that time, on receiving material
preserved in formalin from Munich, it was at once apparent that the
secretion which appears as glistening droplets in the living plant,
was intact and still adherent to the glands, and could therefore not
be a mucilage. (...) Examination showed (...) that they exude a
resinous secretion. There are no other glands, so that on this
evidence (sic!) the carnivorous habit seems to be quite excluded.
"

Lloyd (1942) does not cite the paper by A.N.Bruce (in Not. Roy. Bot.
Gard. Edinb. 17:83-98, 1907) in which digestion of albumin by
_Roridula_ was described.

Not old enough, I'm afraid.

Someone from Germany (Munich; apparently from the group of Goebel,
who was Lloyd's former boss) has even sent material to Lloyd (v.s.).

Not only. Lloyd (1942) mentions also own observations (v.s.). Any
further comments, anyone?

Kind regards
