sessile stigma. It differs from the sectional character in 
the spathe being neither white nor green; but so do some 
of the species placed in it by Engler himself, notably a 
subsection iii., which he describes as having green or red 
spathes, and to two species of which Dr. Masters thinks 
A, Chamberlaini is allied, namely A. formosum, Schott, and 
A. bogotense, Schott. Both these however should have, in — 
accordance with the character of subsection ui., the spadix 
much longer than the spathe; but here again is an in- 
consistency, for of A. formosum the spathe is described as 
two diameters long, and the spadix as only one and a half. 
Another character of sect. Cardiophyllum is to have the 
fruiting sepals very acute, which is hardly consistent with 
the truncate flowering sepals of A. Chamberlaini. In short 
I am obliged to confess that I cannot make this plant fit 
mto any of Engler’s sections, and can give no better guess 
at its affinities than did Dr. Masters, to which I may add 
that it differs from formosum (which has a rosy spathe), 
in the stipitate spadix, and from bogotense in the spathe 
being longer than the spadix. 
The native country of A. Chamberlaini is not known, 
but presumed to be Venezuela, as it was imported with 
Catileya Gaskelliana, which comes from that country. The 
Specimen here figured was presented by Mr. Chamberlain 
to the Royal Gardens in 1892, and flowered in February, 
1893.—J. D. H.
