the paper are the female flowers, the pistillidium (arche- 
gonium) before, during and after the fertilisation, the cole- 
sula (calyx}, the female bracts (folia perichætiala), the 
situation of the female flowers, the male flowers, the anthe- 
ridium, the male bracts (folia perigonalia), the paraphyses, 
the male inflorescences, the situation of the male inflores- 
cences, the distribution of the sexual organs, and the 
blooming-time of the Jungermanniæ foliosæ.

Jr Mniom medium the author has observed an interesting 
case of what be names acrosyncarpia monochætica ; one 
fruit was supported by two pedicells.

A very interesting paper. Necker’s old name colesula 18 
proposed for what bryologists generally name calyx or 
perianthiom in Hepaties. As for the formation of the calyptra 
in Hepatics there are two different cases to be seen; ina 
part the calyptra (c. gynomitriea) is formed exclusively 
out of the pistillidium (archegonium) ; in other Hepatics, 
as f. i, in Trichocolea, the apex of the stem takes an impor- : 
tant part in the formation of the calyptra (c. thalamomitriea). 
The situation of perichætia (female flowers) and androecia 
. (male flowers) are discussed. | — 
Further the author gives his opinion on the systematical 
_ arrangement of mosses. The Hepatics stand on a higher 
degree of development than Bryineæ. Amongst Hepatics 
Marchantiaceæ are to be placed in the first room ; the 
Anthocerotaceæ on the contrary in the last room. Amongst 
the Bryineæ the acrocarpous mosses are higher developed 
than the pleurocarpous mosses ; the Polytrichaceæ being 
the highest, the Andreæaceæ the lowest amongst ‘the 
_acrocarpous mosses. Amongst the pleurocarpous mosses 
the genus Thuyidium is considered as best developed ; these 
_ mosses are, however, rather monotonous, on which account 
their systematical arrangement is very dificult. He
