transitional zone, but less well developed. Others (e. g., 

 Umbilicaria flocculosa)^ skip the transitional region entirely. 



Few strictly typical southern lichens have been recorded 

 from Maine, but it is very probable that a careful exploration 

 of York County would bring southern species to light. This 

 is suggested as a promising field for local collectors. 



Recent Additions to the Flora of Maine. 



Prof. M. h. Fernai^d. 



[Abstract of lecture.] 



Since the meeting of the Society, in July, 1909, many 

 plants have been added to the flora of the state. Of these 

 about twenty-five are not only new to the state, but additions 

 to the range covered by Gray's Manual. 



Among some of these interesting plants exhibited were 

 Limosclla aquatica, var. tcnniflolia, 3. little plant of brackish 

 or saline mud, which was long ago reported from Scarboro, 

 but the occurrence of which in Maine has been doubted. 

 This was found in 1909, at Winnegance. 



Elsholtzia Patrini is a little blue-flowered mint, with the 

 fragrance of lemon verbena, native of Japan and China, 

 which became in some way introduced and established in 

 1887, about Lake Temiscouata, in Quebec. It has now 

 spread along the Canadian Pacific Railway and the Bangor 

 & Aroostook, and is common near the station at New 

 Limerick. 



Barbarea vulgaris, var. hirsuta, a variety of the yellow 

 rocket with hairy, instead of smooth leaves, is found in fields 

 at North Berwick, the only place known for it in America. 



Brassica alba, the white mustard, differing from our 

 other mustards in having the pod very bristly and the upper 

 half flat and beak-like, is a common weed about Eastport, 

 but unknown as a wild plant elsewhere in the state.
