420 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
characters of Linum sulcatum Riddell, and its bracteal leaves some- 
times show a submarginal thickening that recalls the trinerved 
leaves of that species. Linum sulcatum has been attributed to 
Nantucket, and I suppose there is no doubt at all that this species 
was mistaken for it. 
In addition to numerous specimens collected on Nantucket, 
Marthas Vineyard, and Long Island the following collections may 
be cited: Georgia, Cobb County, dry woods, elevation 1,020 ft., 
July 12, 1900, Roland M. Harper 213. Alabama, Clay County, 
Sept. 24, 1897, F. S. Earle 947; Coosa County, Sept. 29, 1897, F. 
S. Earle 1035. These specimens are the only ones I have seen 
from south of New Jersey, where I collected the plant at 
Wildwood, Cape May County, May 31, 1897, just in flower, 
and where Mr. Norman Taylor has more recently collected it at 
New Brunswick, Middlesex County, and also in Monmouth 
County. 
The purport of the evidence would seem to be that Linum 
intercursum is a plant of the coastal plain from. Massachusetts to 
New Jersey, extending southwestward in the hilly country into 
Alabama, while Linum floridanum is a coastwise species of the 
southern states, passing inland at low elevations and ranging from 
North Carolina to Mississippi. The most northern specimens 
I have seen of the latter are from Craven County, North Caro- 
lina, collected at Newbern, Aug. 1, 1898, Thos. H. Kearney, Jr., 
1978. Apparently it is a plant of wet pine barrens and low 
grounds, whereas Linum intercursum inhabits preferably dry 
sandy places. 
SIMARUBACEAE 
*AILANTHUS GLANDULOSA Desf. : 
In 1899 this tree had become established at several places 
the neighborhood of the town. It has not since greatly increased 
its foothold and though slowly spreading scarcely strays away from 
places where it was originally planted. It is also spontaneous se 
Siasconset. It comes into leaf later in the season perhaps than 
any other Nantucket tree. As late as June 7, 1911, it appear 
nearly naked, showing only small tufts of coppery red leaves at 
the tips of the branchlets.
