BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 425 
Common in low thickets. _ In'full flower June 1, 1909; June 8, 
1910; corolla broadly cylindric, variable in size, becoming 8-9 
mm. long and 5-7 mm. wide, sometimes considerably smaller; 
ripe fruit Aug. 6, 1906, Aug. 9, 1908; berry blue and very glaucous, 
becoming as large as a half inch in diameter. 
The handsomest of our high bush blueberries. In its typical 
form the thick entire leaves, bright green above and often glau- 
cescent, are whitened on the lower surface, and are wholly glabrous 
even in vernation, except sometimes for a minute pubescence 
along the midvein on the upper face. Quite possibly intergrades 
or hybridizes with V. corymbosum. 
VACCINIUM ATROCOcCCUM (A. Gray) Heller. 
Common in the dense thickets of low grounds, often associating 
with V. corymbosum. Last flowers, and young fruit, June 10, 
1908; some ripe fruit July 11, 1912. 
At Coskaty on Aug. 14, 1906, a form was collected bearing the 
characteristic dark shining fruit, but with the leaves very acute 
and more or less serrulate, or some of them entire, thus answering 
to Michaux’s description of his V. disomorphum. Bigelow, long 
ago (FI. Bost. ed. 2, 151. 1824) correlated this name with the shrub 
we now call V. atrococcum, and it comes out pretty clearly that his 
judgment was correct, unless a distinction is to be discovered 
between those shrubs having strictly entire leaves and those with 
the leaves subserrulate or sometimes entire as Michaux described 
them. His Latin, ‘‘folia . . . subtus pubentia, interdum integri- 
uscula . . . corolla albido-purpurascens, oblonga, ovoideo-urceolata”’ 
quite definitely excludes V. corymbosum as well as all other 
northern species at present recognized, except V. atrococcum. 
* Vaccinium vicinum sp. nov. 
Characterized by a close soft pubescence, similar to that of V. 
atrococcum, and large flowers as well as glaucous fruit, more like 
that of V. corymbosum; the leaves, more or less serrulate, but 
often entire, are commonly narrower than in either of those species 
and of marked oblanceolate or obovate-oblong tendency. 
An openly branched shrub 1-2 m. or more high; branch- 
lets and young leaves beneath tomentulose-canescent or villous-
