Stem thick, red, lateral, sometimes wanting. BuLurarp ; 
whose admirable drawings should be consulted in order 
to gain a good idea of the structure of this very singu- 
lar plant. When grown toa good size it looks exactly 
like a piece of beeve’s liver. In the different figures 
cited above the under surface appears of very different 
“colours, which Mr. Bulliard attributes to the presence or 
absence of pink coloured roses which close up the mouths 
of the tubes, but are detached before the seeds are poured 
out. This may in part account for the change, but it 
may be observed that the tubes themselves are also of 
different colours, viz. greén, and brown red, Butt. +64, 
. 407, Bott. 79, Micu. 60, and Scuzrr. 117, 118; 
forming the green tubed, and the others the red tubed 
species or variety. Not having had sufficient opportuni- 
‘ties of examining the plants in a recent state, 1 mention 
these circumstances in Hopes that others who more fre- 
quently meet with them, will attend to them at diffe- 
rent ages, and determine the matter. The figure of Mi- 
cheli is excellent, and the structure of the tubes did not 
escape his penetrating eye, as appears by: the dissected 
figures at the bottom. He remarks that the pileus 1s 
rusty red, the flesh blood red, the tubes dirty dull yellow, 
bordered at the mouth. Micw. p.119. This plant at- 
tains its growth in a few days, and is of short duration. 
Buri. Lobes elliptical, generally issuing from a short 
stem. In infancy it is-viscid, pulpy, and exsuding on 
being pricked a bloody water: colour deep red. When 
mature the upper side gets rough and hairy, and turns 
blackish red or deep chocolate.’ ‘The under side does not 
assume the form of pores tilla late period. It appears 
at * cream coloured, and is studded very co eb 
wit r-coloured pimples, interspersed with some of a 
bl id vod. PHNpsess ei gaete : 
The pores and tubes are extremely minute, being like so 
many needles huddled together, nor is the aperture of the tubes 
very discernible without being magnified, They are hardly z
