ig2 The It ish Naturalist. September, 



Poa. IL may be noted that it is possible that the Atriplices 

 of the two lists are identical, these plants being far from 

 mature in July, the date of both our visits. 



Two or three plants in my list require more particular men- 

 tion, Isoetcs lacustris grew sparingly and very dwarf on peat 

 in a few inches of water on the south-west shore of lyougli 

 Ahooe}'. Cochlcaria graenlaiidica, a rare west coast plant in 

 Ireland, was in Donegal previousl}' known from a couple of 

 stations in the Rosses; it was seen in two spots on Tor}^ near 

 the edge of the cliffs. Of the Potainogetoii pcctinatus^ Mr. 

 Arthur Bennett writes :—"var. salrmis, Voch. = var. pscudo- 

 mai'bnis^ Ar. Benn. It is a form which has been frequently 

 named P. viarinus, !,■, by some Central European botanists, 

 and is, I believe, what is so named in some English floras." 



Four species which were recorded b}' Hyndman were not 

 seen b}' Barrington, namely, C^'avibe mai-itiina^ Erica Tetralix, 

 Gcntiana campestris^ and fitniperus cojiiviunis. None of them 

 were found b}' me either. The first is probably extinct, and 

 the last, no doubt, an error; the second and third ma\' 

 possibly still linger in some corner, though ver}' possibly 

 exterminated bv the cutlins: of sods.

MOSSES AND HEPATICS. 



BY RKV. CANON H, ^V. LETT, MA. 



Taking long drives through beautiful scenery to the accom- 

 paniment of agreeable companions is not the best way for 

 examining the flora of a district, though it is a most enjoyable 

 way of spending a holiday. And the all-too-short time 

 provided by each day's excursion from Rosapeuna for " moss- 

 trampmg," did not make it possible even for the most 

 enthusiastic to get into, or search thoroughly any of the most 

 likely places for mosses and hepatics. So that the record of 

 the.se plants collected during the Conference week, b}- H. W. 

 Eett, J. Glover, and R. El- Praeger, is not so large as might 

 otherwise have been anticipated from the localities that were 

 visited.
