386 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
belongs to the wild flora of the island. How long it has grown 
there and by what agency it became established may never be 
known, but it is to be hoped that its station will be rediscovered 
and careful observations made to ascertain if there be not in the 
surroundings some hint as to its origin there. 
Mrs. Owen has told us that in days now long past persistent 
efforts were made to increase the heather on Nantucket, and that 
seeds of both purple and white heather had been sown on the— 
commons. Presumably these seeds came from Great Britain 
and the white heather referred to was the white-flowered form of 
the Scotch heather or ling. Erica vagans, sometimes called the 
Cornish heath, is a species more especially of the Mediterranean 
region, and is of local occurrence only as far north as the British 
Isles. It has occasionally been offered here in tradesmen’s cata- 
logues. 
*Cuscuta EpirayMumM Murr. 
Specimens in full flower have been sent to me by Miss Gardner, 
collected by her in Squam August 19, 1915, growing on Laciniaria 
scariosa (Willd.) Hill. 
Note.—In a paper by the late Professor John H. Sears (see 
Rhodora 10: 43. 1908) is a list of plants of more southern dis- 
tribution that occur in Essex County, Massachusetts, with mention 
of their nearest known stations south of Boston. Included in this 
list is Cuscuta arvensis Beyrich, its nearest station south being 
given as Nantucket. 
GALEoPSIS TETRAHIT L. 
Mrs. Flynn has sent mea specimen of this species collected in a 
waste place west of the town August 14, 1911, a much branched 
and well-seeded plant bearing some late flowers. Both this species 
and Galeopsis Ladanum L. have already been mentioned in this 
list, having been admitted into Mrs. Owen’s catalogue. No other 
evidence has appeared respecting the latter as.a Nantucket plant. 
*CLINOPODIUM VULGARE L. 
Satureta vulgaris Fritsch. 
Miss Alice O. Albertson has sent some flowering specimensof this 
mint collected by her September 16, 1916, in a field opposite the 
Franklin Fountain where it was first discovered by Professor
