452 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
The tenacity with which this rose keeps its foothold when once 
rooted is well shown by a vigorous cluster, which was found in 
1907 flowering on the exposed ocean front on the south shore of 
the island, at the site of the old Surfside hotel. The hotel, I am 
told, was demolished in 1901 and had been abandoned some years 
earlier, and this rose remained the sole vestige of the planting 
that had brightened the wind-swept and barren spot nearly a 
decade before. 
*PyRUS COMMUNIS L. 
Occasionally met with in a wild state, sometimes in far out of 
the way places. Small trees are frequent in pine scrub south and 
southeast of the town. A single tree, about seven feet high, grows 
in a wild thicket towards Quidnet, and a small tree similarly iso- 
lated was found in Squam. The only wild tree met with, bearing 
fruit, grows among scattered pines on the commons, perhaps two 
miles east of the town; on June 14, 1911, it was about nine feet 
in height and measured eighteen inches around, six inches above 
the base. 
*Matus Matus (L.) Britton. 
Frequent among the pines along the old south road, where, 
I was told, it produces an abundance of small fruit; occasional by 
roadsides and in old fields, often in a dwarfed or straggling condi- 
tion; Squam; Surfside road; on the bluff at Siasconset; a tree 
about fifteen feet high in woodland at Beechwood. Still in blossom 
June I, 1909. 
ARONIA ARBUTIFOLIA (L.) Medic. 
Common in low thickets and pond borders as well as in per- 
fectly dry soils, even in pine woodland. Just in bloom May 30, 
1909; everywhere in conspicuous blossom June 17, 1911. 
*ARONIA ATROPURPUREA Britton. 
Common in dry open places as well as in low grounds. Often 
untypical, indicating an involved relationship with the preceding. 
First flowers May 30, 1909; some blossoms remaining June 15, 
IQIO. 
*ARONIA NIGRA (Willd.) Britton. 
Infrequent, boggy spots near Gibbs Pond; Wigwam Pond; west 
of Sachacha Pond; near Long Pond; Quaise; Siasconset; a solitary
