STR, 
N my laft letter I mentioned I had fown fome of the fine duft 
L or farina from the MISSIS of Lycopodium cernuum, and 
that from the capitula, generally called antherz, of Bryum cefpi- 
titium, or a fpecies very s it, pat I then thought their fuccefs 
fomewhat doubtful. 1 have fince repeatedly fown them both, andi 
in a proper fituation find they grow very readily. 
Encouraged by this, I fowed that curious part of the fruétifica- 
tion of Marchantia polymorpha, compofed of fine elaftic filaments: 
and {mall globules (commonly confidered as the male parts), where: 
none of thefe plants had ever been before. In a fhort time I 
found there feveral young Marchantia, which are now growing 
freely. I lament I could not get any of the genus Egui/etum, for a. 
fimilar trial; but am much inclined to believe that the farina,. 
from its fruétification, will likewife produce young plants. - 
From thefe inftances of young plants being prodüced from 
thofe parts of the fructification of Cryptogamous plants which 
‘have been, as far as I have been informed, hitherto confidered:
