BACCHARIS HALIMIFOLIA L. 
Very local, and confined to the eastern side of the island. As 
long ago as 1849 it was rather numerous on Coskaty, according to 
Mrs. Owen, and it is abundant there today. It occurs also on 
Coatue, and extends sparingly from Polpis southeasterly towards 
Siasconset, well away from any direct saline influence. A single 
small plant was seen in one of the higher bogs on Saul’s Hills, 
and a shrub nearly seven feet tall in Gibb’s Swamp. In 1904 a 
large clump grew in dry open ground about a mile northwest of 
Siasconset. Not yet in bloom September 6, 1904; in full flower 
September 17, 1899.

plants were in bloom; mostly gone to seed by June 15, 1910. 
forms with broad rounded leaves, and 
forms with narrowly oblanceolate leaves on elongated petioles 
(var. petiolata Fernald) often growing side by side. A small form 
having narrow and acute leaves, collected in the Miacomet pines, 
is especially noteworthy by reason of reddish glandular hairs 
scattered along the stems, these being oe aa 
examples. More noteworthy still is a very small form foun 
also among the Miacomet pines. It is at once set apart from
