T h e r e has been considerable v a i i e t y of opinion as to the place of Popotvia amongst
t h e genera of Anonaceoe. The genus was founded by Endlicher (Genus No. 4710) to
accommodate the specics which had been named Bocagca pisocarpa by Blnme \_Flora
Javoe [Anonaceoe] 90, t. 45]. Endlicher placed it next to Orophea, from which it is distinguished
by its inner row of petals being free and having then- apices iuflexed in
oestivation, while those of Orophea arc clawed, vaulted, attached by their edges, and
not inflexed in estivation. In their Flora Indica Hooker filius and Thomson added
t h e species F. ramosissima to the original plant of Endlicher, with a remark to the effect
that Ucaria Vogelii, II. f., should be included in the geims. Fui-ther they associated
I'opozBia with the genera Orophea, Mifrephora and Goniotkalamus in the tiibe Mirtephorece.
In their Genera PLantarum Mr. Bcnthani and Sir Joseph Hooker take a different
view of the position of Fopowia and, in the arrangement adopted in that great
work, Popowia is put amongst the Unonece ; Orophea is relegated to the tribe Miliuseoe ;
while Goniotkalamus and Mitrephora are retained side by side in the tribe Mitrephorece.
Now the character of the tribe Unonece is " petals flat, slightly unequal, or those of
t h e inner row smaller than those of the outer, or absent," while in several of the
Popo-wias (e.g., P. pisocarpd, P. rainosisdma) the inner petals are longer than the outer.
Bâillon, whose arrangement of tribes differs f r om that of Messrs. Bentliam and Hooker,
puts Popowia into Unonece, leaving Mitrephora and Orophea side b y side in his tribe
Dr. Schcffer differs from the opinion of the authors of the Genera Plantarim and of
Bâillon, and i-ather inclines to that of the authors of the Flora Indica. He points out
with much force that the proper place of Popowia, is in the tribe characterised by its
" o u t e r petals being open, the inner connivent over the andro-gynoecium, erecto-conniveut
or connate''—that is to say, in the tribe Mitrephoreoe of these authors. The stamens
of Popowia present considerable diversity, but on the whole t h e y have the character of
those of Uuarioe rather than those of Vnonece. As Scheffer remarks, there is little
difference between the genera Orophea and Mitrephora except that the outer petals
of Mitrephora are usually larger than those of Orophea. And, if M. Baillon's plan of
reducing the number of the genera in Anowicece were to be carried out, Dr. Scheffer
would suggest the union of these two and of Popowia into a single genus, from which
would be excluded, however, all the African spccies. Of these new genus Orophea
would be the tyi^ical form, and the other two would f o rm sub-genera.
T h e r e is no doubt that in externals many species of Popowia are like Orophea; and
t h e iion-unguiculate character of the inner petals is really the best character by which
to distinguish them from Orophea.
I venture to follow Dr. Scheffer and the authors of the Plora Indica in putting
Popowia, Orophea, and Mitrephora together in the tribo Mitrephorece.
