REVUE BRYOLOGIQUE 19 
from my own experience, For getting such dates I have 
found it connected with the least labour to collect small spe- 
cimina of the moss that I desired to examine frorr. different 
parts of a year, for instance one specimen from each fort- 
night, and afterwards to examine all the collected specimina 
at once in the winter. It is, however, of course even only in 
the first year in which these observations are made in a sta- 
tion, that it is necessary to collect specimina from every sea- 
son, as it in following years is clear from the researches of 
preceding years about which time the blooming begins, on 
which account it is then sufficient to collect specimina for 
examination only from about this time. The fructification 
is, on the contrary, much better adapted to phænological ob- 
servations in mosses, at least in stegocarpous mosse 
which the time of the detachment of the lids is s0 easily: 
served, than in phanerogams, on which account I do not 
think any further pleading my proposing observations on 
this phenomenon necessary. 
Both the aboye-mentioned kinds of phenomena, the bl 
ming and the fructification, I think, are most properly to b 
observed in mosses, as is also most commoniy the case iu 
phanerogames, at their beginning ; this stage of forination 
ing considered to have entered at the blooming, when in 
a species in at least ? flowers only one or two archegonia 
are opeued, while,on the contrary, the other archegonia are 
still closed and uncoloured, or, if archegonia are not acces- 
ee ET 
antneridia are Op! and uncoliqurea or DrOWH, W} » y: 
the contrary, all he other antheridia are still closed. In de- 
termining the blooming-time ought, however, if archegonia 
are at hand, these in the first place to be consulted ; because 
we are less subjected to errors when determiuing the bloo- 
ming-time.of a moss according toarchegonia than a 1 
to antheridia, Especially I dare warn observers of belie- 
ying the blooming to have entered in a moss only because 
its antheridia may appear fully developed, if not ai the same 
time gny antheridium is opened, as antheridia may oflen 
appear fully developed many months before their being 
opened and before Hier anthergoids begin to swarm. The 
fructification I have, on the contrary, believed be 
sidered to haye begun when in a sREcIE Île
