88 Rhodora (APRIL 
larity of Falmouth (of which Woods Hole is a part) as a summer 
resort, and the corresponding decrease in the amount of neglected 
and waste land has brought about some changes in the flora, some 
species once common having become rare, while many new ones 
have been introduced. It has seemed worth while to publish these 
notes, not only to record the introduced forms, but also several 
species not previously reported east of Rhode Island. While the 
geographic position of Woods Hole is such that the occurrence of 
these species is by no means surprising, it is none the less worthy of 
note. It will be interesting to observe how many and which of the 
introduced species persist. The plants marked with an asterisk (*) 
were kindly identified for me at the Gray Herbarium. 
Bromus hordaceus L. Not rare along roadsides. 
Bromus tectorum L. Found once, in 1899. 
Scirpus olneyi Gray. Abundant in some of the salt marshes along 
the Sound between Woods Hole and Falmouth. 
Habenaria clavellata Spreng. (H. tridentata Hook.) A single 
small specimen of this orchid was found on the edge of the salt 
marsh between Eel Pond and Buzzards Bay. 
* Chenopodium anthelminticum L. Found August 9, 1899, at a 
dumping place on Penzance, but not observed in 1900. 
* Tetragonia expansa Murr. Growing with the preceding in 1899, 
but not found in 1900. 
Myriophyllum pinnatum (Walt.) B. S. P. (M. scabratum Michx.) 
Not rare. 
Dianthus barbatus L. Found on low waste land on Penzance in 
1900, not previously noted there. 
Lunaria annua L. Found once in 1899 in a waste place beside a 
woodland road. 
Genista tinctoria L. While not seen at Woods Hole this species 
occurs across the “ Hole " on Naushon Island. 
Cytisus scoparius L. Common in the field back of the Fish Com- 
mission work-shop, where firmly established. 
Foeniculum foeniculum (L.) Karst. (F. vulgare Gaertn.). Found at 
a dumping ground on Penzance in 1899 and persisting at the same 
place in 1900.

found there in 19oo. It has also been noted in a lawn at Tempest 
Knob, Wareham in 1899.
