180 ON MONOTROPA HYPOPITYS, 
dead, and shrivelled, often for a length of an inch or more. All the 
younger parts of the rhizome and its ramifications are whitish on the 
surface, which is the result of a close felt 4 iMeohe, with very small, 
globular, and uneoloured spores; this covering is especially con- 
spicuous in places where the branches of the rhizome have been 
lying against some hard object, as stones, . &c. 
Microscopical investigation shows that the rhizome is for the most 
part built up of rounded cells, without any thickening, and containing 
no starch, but filled with a watery and somewhat viscous juice, sur- 
rounding a very conspicuous nucleus and nucleolus. Many of these 
cells, especially those surrounding the central fibro-vasoular fascicle 
i d 
is constructed of distinctly smaller cells, without any thickening, and 
shows no trace of corky tissue. I wasalso unable to find anywhere 
root-fibrils or a terminal root-cap. The fully-developed plant thus 
seems to want all roots, and to absorb its food by the whole surface of 
evidence both of the rapid gr f the 
anterior extremity, and of the quick decay of the posterior end of the 
hi é peduncle agrees with the rhizome in all essential points 
of structure, and it j is impossible to detect any stomata on it or its 
bracts, or on the calyx ; their absence explains the total absence of 
chlorophyll in the whole plant. 
In the fresh state Monotropa smells very much like the Tonca- 
bean, the Meliloti, &c. ; ; ie taste is that of raw peapods, mingled with 
a slightly aromatic flav, 
Any part i the plait from which by pressure in the living state 
most of the juice has been squeezed assumes very. slowly and im- 
pea he dark-ue olour. In Monotropa this Dear airy which 
is foun: more or less true parasites, seems to be occasioned 
iy the Gotibite of the sulle during desiccation depositing the above- 
m freon ned small dark granules on the inside of (also in ?) the cell- 
membrane
