N. Lat., and A. Grimme, in Germany, with regard to the seasons of the 
blooming (Bloom.) and the maturation of the fruits (Fruits.) of mosses in 
question, as also with regard to the time (expressed by the number of 
months) which these mosses require for the development of their fruits 
(Devel ). The days are expressed by the usual figures, the months by 
Roman numerals, as I (January), II (February), etc. 
From the above table it will be seen that the results to which Grimme 
and I have come are similar, if the differences due to latitude are considered. 
With regard to two mosses, Dicranella cerviculata and Stereodon polyan- 
thos, our results show greater difference: acording to my experience in 
Sweden, Dicranella cerviculata requires about twenty months and Stereo- 
don polyanthos eleven months for the development of the sporophytes, while 
these mosses require in Germany, according to Grimme, the former species 
only twelve months and the latter species fifteen to nineteen months for the 
same purpose. The dates contained in the table afford material for many 
interesting comparisons, and I hope they will induce some readers of The 
Bryologist to examine the phaenological relations of the same mosses in 
their locality and by publishing the result procure more material for com- 
parison. Upsala, Sweden. 
NOTES ON THE FRUITING SEASON OF CATHARINEA. 
Phebe M. Towle, 
During the season of 1903 some attention was given to the fruiting sea- 
son of the Hair-cap moss, and the report was published in The Bryologist 
of March, 1904. 
Observations for the sake of verification were repeated on the Hair-caps 
in 1904, with the same conclusions as were noted for 1903. 
This same line of observations was followed during the season of 1904 
with reference to Catharinea undulata. 
This Catharinea is abundant about Burlington. The stations visited 
were in the ravine north of Colchester avenue and along the brook which 
runs through the woods of Fair Holt. Another station was along the bank 
of the Missisquoi River. 
On the first trip afield, the last of March, Catharinea was found with the 
capsules shedding their spores freely when disturbed. This continued 
through April, the spores coming out in clouds. 
On April 29th Catharinea rosettes were conspicuous. The antheridia 
were green in color, but had a narrow, clear space at the top. None of them 
were ready to shed their contents. 
May 3d, Catharinea tufts contained archegonia of different heights but 
none were open. 
May 7th, the antheridia were discharging sperm mother-cells, and 
three of the five archegonia of a female plant were open. There were five 
archegonia in each of the Catharinea tufts examined. When the archegonia 
were open they presented a well spread border around the top of the tube.
