Mrs. Gepp to whom I showed my plant during åa visit to London 
in October 1907 then agreed with me; later on after having seen 
an original specimen of Avr. levis Howe, I have some doubt if my 
plant really could be referred to this species; but having only one 
specimen and therefore not being able to form any opinion as to

and further the increasing of the diameter of the outmost branches. 
Also the habitus of the plant is rather different from A. Jemis, my 
form being much larger, of a looser consistency and the flabellum 
with a lacerated and lobed margin.
