base of the spadix, a short distance above these isa ring 
of sessile anthers, occupying about a quarter of an inch, 
and both above these, and between them and the germens, 
about an equal space is occupied by filiform cirri or sterile 
stamens ; the upper part of the spadix is club-shaped, as in 
the common Arum, but always of a pale yellow colour. | 
‘It was in this species that M. Lamarck observed an 
extraordinary degree of heat, amounting almost to burning, 
in the spadix, at a certain epoque; probably that, when 
the fecundation of the germens takes place. This high tem-. 
perature continues only for a few hours, and when several 
spadices come from the same root, the heat is evolved from 
each, in succession, as they arrive at the proper epoque, 
while the rest remain at the same temperature as the sur- 
rounding atmosphere. This observation is said to have 
_ been confirmed by DesFonTaInEs. Peete 
We are not informed, however that the fact was proved 
by the thermometer ; and, if not, itis possible that some 
pungent vapour might occasion the sensation of heat in the 
fingers, without cabs increasing the temperature of the 
surrounding air. We hope some of our readers may be . 
induced to attend to this curios phenomenon.
