384 Mr. Hooxer’s Observations on Andrea. : 
Fhrhart has a different function assigned to it, surely it would 
be better to retain'the old name of operculum, to which it has 
full as much right as the part which occupies the same place in 
Phascum, and even more so; for in Andrea it is sometimes of a 
different colour, and is always of a different texture, from the 
capsule. Dr. Roth doubts whether the seeds may not, while in 
the capsule, be fixed to filaments of a similar nature to those of 
_ the Jungermannie; but, in all the species I have had an oppor- 
tunity of examining, I have not been able to observe any tbing 
of the kind. | : 
Thus was Andrea removed from one order to another, as if its 
parts of fructification were among the minutest of the vegetable 
kingdom, or among the most difficult to examine, till the late 
Dr. Mohr-in his Flora Germanica, (of which he sent an unedited 
copy to his friend Mr. Turner a little before his death,) by a con- 
cise definition of the two orders Musci and Hepatice, satisfac- 
torily established it as belonging to the former of these, which 
he calls ** operculate,"* but he has still peser in capes the 
valves of the capsule a peristomium. = se 
Having thus delivered my opinion as to the order to which 
Andrea properly belongs, it remains for me to say a few words 
upon the place which in that order it ought to occupy ; and here 
I trust no doubt can be entertained of the rs of ra 
-.* Dr. Mohr’s 6th order of the. class Cryptogamia, which he nuls; E casei is 
sde into 
a. Operculate, containing all the true Musci, among which ccr alate 
the last ; 
b. DIU aiuta; which includes all the Hepatice, 
. However excellent the definitions of these subdivisions may be, it seems hardly ne- 
cessary to alter the old terms of Musci and Hepatice. See Dr. Smith's on Bri- 
lannica, 1099; 1101,
