314 Ma, Linpsay's Leiter te Sir "fofepb Banks, 
as the male parts, I have little doubt but it would be found on a 
fair trial that, in a very great proportion of Cryptogamous plants, 
the real female parts have been miftaken for the male. 
In this view thé Marchantia bearing feeds of another kind in 
fmall feflile cups, which alfo readily grow, may give the appear- 
ance of unneceflary fuperfluity; but in this refpect the Marchantia 
is not fingular. May not this daft kind of feeds be confidered 
as in fome meafure analogous to thofe luxuriant. productions 
of young plants in many vegetables (hence called Viviparous) in 
place of feeds, rather than as a neceflary part of the genuine fruc- 
tification? Such examples are frequent in the tribe of Graming, 
in the genus Æ/ium, and others, and alfo among the Cryptogamous 
plants. There is à fern here, feeming a Péeris, growing by 
the edges of ponds, which is plentifully propagated by the fall- 
ing of the leaves loaded with young plants into the water; yet 
this has its fruétification and feeds in the ufual manner, and the 
feeds readily grow.

THE foregoing obfervations of Mr. Lindfay are highly worthy 
-of attention, as confirming the Hedwigian theory of the fructifi- 
cation of mofles; and the refult of his experiment on the Bryum 
was the fame with thofe made on the fame genus by Hedwig. 
The raifing of any fpecies of Lycopodium from. its farina has not 
to my knowledge been defcribed as practicable; Mr. Lindfay,
