THE WATER TUBES OF CONOCEPHALUM CONICUM. 
151 
The hairs arise in large yellow-brown cells which form a cap 
over the stem. The top of this cap is excentric with the stem, 
being, as shewn, nearer to the growing end of the frond. 
I find no trace of similar hairs in the fructification of Lunularia 
cruciata : but the young carpophore as it emerges is entangled 
with hairs from the surrounding bracts — these hairs are, however, 
of a different nature, being chains of cells. Similar hairs are 
given off from the stem which has no tube running through it. 
See Fig. 5. 
Chains of cells forming hairs are also found on the under side 
of Reboulia hemispherica, but its stalk has a tube and it appears 
to carry hairs from the cap somewhat as Marchantia does. My 
material is insufficient to work it out thoroughly.

Water-tubes of Conocephalum conicum : —

cephallum conicum. A, cap of chlorophyllaceous tissue ; B, 
sporangia with spores and elaters ; C, hairs with peg-like 
intrusions.

it ; C, stalks of separate sporangia.
