his own hand-writing, so it may be taken that he named the specimen. 

 Miss Lawless cannot say where she gathered the plant. Not seen since.] 



Hieracium hypochaeroides, Gibs., var. saxorum, F. J. H. — In good quantity 

 on the Croaghmore cliffs at about 1,100-1,300 feet. 



H. anglicum, Fr. — With the last, and also on low sea-cliffs at Doontraneen. 



Leontodon autumnalis, L., var. simplex, Duby. — Frequent at the west end of 

 the island. A very small glabrous plant with unbranched flower-stems 

 and almost entire leaves. 



Taraxacum officinale, Weber, var., crythrospermum (DC). — On sand at the bay 

 beside the Harbour. 



Erica mediterranea, L. — Abundant on boulder-clay slopes (no trace of peat) 

 facing north-east, from storm-level to about 70 feet, between Portlea and 

 Ooghcorragaun ; flowers very pale, the corolla being practically white, 

 with a pink edge. A couple of outlying plants on top of the low cliff at 

 east end of Portlea. 



I was interested to discover what insects were fertilizing the flowers of 

 this plant on these sunless northern banks in March, and spent half an 

 hour capturing the insects which came to the blossoms. They numbered 

 four flies and one bee, which Messrs. Grimshaw and Halbert identify as 

 Scatophaga stercoraria 3 and 2 , Fucellia fucorum ? , Pseudopyrillia. 

 cornicina ? , Eristalis tenax 2 ■ No mention of this Heath or its 

 fertilization occurs in the well-known works of Muller or Knuth. 



Euphrasia officinalis, L. — E. brevipila, Burn. & Gremli, and E. gracilis, Fr. are 

 common; E. occidentalis, Wettst. ; E. curia, Fr., var. glabrescens, Wettst.; 

 and E. scottica, Wettst., are rarer. 



Bliinanthus Crista-galli, L. — The prevailing form is R. stenophyllv.s, Schur. 



Orelianche rubra, Sm. — This interesting plant was added to the flora on the 

 occasion of my last visit to Clare Island. It was descried from the light- 

 house yard growing sparingly on the cliff below; and Mr. Duffy, -head 

 light-keeper, kindly went down on a rope and procured a specimen. 



Thymus Chamaedrys, Fr. — In several spots, but much rarer than T. Serpyllum. 



Salix herbacea, L. — A couple of patches on Croaghmore at 1,000 feet, and 

 another at about 1,400 feet. 



Juniperus nana, Willd. — One patch on a small inaccessible sea-stack near 

 Doontraneen, about 70 feet elevation. 



Cephalanthera ensifolia, Eieh. — A few small plants, flowering sparingly, on a 

 boulder-clay slope facing north-east, 50 feet above the sea, between 

 Portlea and Ooghcorragaun. Found by D. J. Scourfield. Listera oraia 

 also has here its only station, and Erica mediterranea is close at hand. A 

 curious habitat for all three plants.
