In a female flower 72 cM. across, the diaphragm had a diameter 
of 33 and 35 cM.; and its central opening was 16 and 19 cM. 
wide in opposite directions. The inner side of the diaphragm 
possesses the same warm purple colour as the perigoneal tube, 
but it does not carry ramenta. Instead of these we find on the 
under side of it a rather large number of slightly elevated but 
not pedunculated, snow white patches, really the most beautiful 
and positively charming feature of the whole flower. 
These white patches seem to be a sort of disguised ramenta; 
in any case at the base of the diaphragm there are often to be 
found intermediate forms between ramenta and white patches. 
The upper side of the diaphragm is of a light brick red color 
and has a very irregular surface. The most striking feature of 
it is a multitude of rather deep impressions, as if made with 
the top of a finger but with secondary small impressions upon 
their bottom. These impressions are simply negatives of the 
warts of the perigoneal lobes, which have rested against the 
diaphragm, before the bud opened. Upon the bridges left be- 
tween the impressions we find scattered small elevations of 
regular form with a rounded top, of light brick red colour, at 
their base surrounded by a purple coloured line. 
Around the base of the diaphragm are disposed the five lobes 
of the perigony. The colour of their upper surface is a warm 
purple, with exception of a rather large number of low, mam- 
milated warts, about 1 to 2 cM. long which are light brick 
red in colour. The warts are of more or less oval form and do 
not anastomose with eath other. The under side of the lobes 
is of a light brick red colour and covered with innumerable 
white spots, smaller than pinheads. They are generally covered 
with impressions, which are the exact negatives of the warts, 
showing upon the upper surface of the lobes, and they are sim- 
ply due to the fact, that the upper surface of a more supertfi- 
cially situated lobe impresses its elevations into the under sur- 
face of the more deeply placed one. As a consequence the 3 
innermost lobes (numbers 5, 4 and 3) are covered with impres- 
sions all over their surface whereas number 2, which is only 
_partially covered by number 1, has half its surface quite grits:
