BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 385 
of a form found there that I was unable to place were submitted 
to Dr. Bartlett, who wrote me in regard to them under date of 
November 28, 1914: ‘‘ They appear to be my n. sp. Oe. rubescens, 
to be published shortly. The seeds came to me from Professor 
George F. Atkinson, at Ithaca, and were originally collected on 
Nantucket by Miss Grace B. Gardner. I drew up my description 
this summer from living plants.” 
*OENOTHERA. 
Miss Gardner has sent me specimens of an Oenothera collected 
by her on Nantucket, August 24, 1915, which differs strikingly 
from any form I have myself seen there. It is in full flower and 
early fruit and is notable from the perfectly glabrous axis of the 
inflorescence, glabrous capsules and small early deciduous subtend- 
ing bracts; the hypanthium is slender and glabrous, becoming 
over 3.cm. long, and the tips of the calyx lobes are hispid with trans- 
lucent diverging hairs. The leaves subtending the branches, these 
being the only ones seen, are thin, oblong- to ovate-lanceolate 
on slender petioles and thinly short-pubescent, their margins 
distantly glandular-denticulate; the branches are thinly roughish- 
pubescent toward the base, the longer hairs flexuous and arising 
from minute red papillae. 
*HEDERA HELIX L. 
The European ivy flourishes on Nantucket and has become 
locally well-established away from cultivated grounds. On Sunset 
Hill it may be seen running through the grass in dense masses 
and clothing old fence posts and tree trunks with all the vigor and 
luxuriance of our native Virginia creeper. Flowers profusely in 
September. 
*ERICA VAGANS L,. 
Miss Alice O. Albertson has sent me flowering specimens of 
this European heath which were collected by Miss Eleanor Owen 
‘‘among pine trees north of Head of Hummock Pond,” August Io, 
1915. The specimens sent are two small sprays, each bearing 
three clusters of flowers. _ 
Much has been written about the three heaths common in the 
British Isles that have long been known to grow on Nantucket, 
but it seems never to have been suspected that a fourth species
