1921] Long, — Rare Plants from Knox County, Maine 199 



Coronilla varia L. A rare introduction, growing profusely by 

 the side of the old road to Thomaston 



Salix purpurea L. A rare willow in Maine. Established and pro- 

 lifically spreading, at roadside in Rockport. 



Lemna trisulca L. In "Lily Pond" and brook running there- 

 from in Rockport. Second station in Maine. Formerly known 

 from Houlton, where it was collected by Fernald and B. Long. 



Xyris Montana Ries. Found growing in "Meadow Bog," an 

 extensive peat bog near Rockland. A northern species, very rare in 

 Maine. 



Scirpus cespitosus L., var. callosus Bigelow. Another far 

 northern plant growing abundantly in "Meadow Bog." This is a 

 coastwise south-western extension of range from the Mount Desert 

 region. The above named bog needs further exploration. 



Carex aurea Nutt. Wet meadow near " Lily Pond," Rockport. 

 Also abundant in another meadow in Rockland near lime quarries. 

 Rare near the coast, indicating lime. 



Carex granularis Muh'., var. Haleana (Olney) Porter. Shaded 

 banks near "Lily Pond." Another calciphile which is rare near the 

 coast. 



Carex trichocarpa Muhl., var. aristata (R. Br.) Bailey. Pro- 

 fessor Fernald writes: "First east of western New York. A really 

 startling find, for it is so conspicuous that if it occurs between the 

 Knox Co. limestone region and western New York someone ought to 

 have seen it." I find it plentiful on the banks of a brook flowing 

 through a meadow, in a valley between two ranges of hills, in Rock- 

 land. 



Ruppia maritima L., var. subcapitata Fernald & Wiegand. Near 

 the railroad station at Damariscotta Mills in Lincoln Co., not far 

 from Knox Co. Growing abundantly in a small brackish pond 

 where the tide flows and ebbs. First station in Maine, but known 

 both east and west. On the edges of the same pond there is a thick 

 stand of Typha angustifolia L., a somewhat northern station for this 

 cat-tail. 



I am indebted to Prof. Fernald for verifying the determinations of 

 the above named plants. 



Matinicus, Maine.
