FLOWERING PLANTS OF NANTUCKET 3/1 
revive a growth of P. pallida in drying pond holes where it had 
earlier flowered as an aquatic, not infrequently bringing it to a 
second flowering period, and it is to be noted that this interruption 
of its course of growth has a repressive influence, sometimes very 
obvious, both on the plant as a whole and in its parts. Neverthe- 
less between P. pallida and authentic G. Fernaldii there is a certain 
difference of aspect not readily definable and this, together with 
the differing distribution of each as worked out by Dr. St. John, 
may well point to something in their diversity more fundamental 
than a mere response to casual seein in the conditions that 
immediately affect growth. 
Puccinellia distans (L.) Parl. At the only station for this 
grass known to me on Nantucket, where it is in abundance, well- 
developed plants possess all the characters of typical P. distans 
as defined by Fernald (Rhodora 18: 12-13. | 1916), while reduced 
examples, these the more numerous, correspond perfectly to the 
description of var. tenuis (Uechtritz) Fernald; intermediate forms 
grow with the extremes. 
Festuca octoflora Walt. Not uncommon, and rather widely 
distributed: near the Cliff; Island View farm; Tom Never’s 
Swamp; Madequet. 
Festuca myuros L. Widely scattered and growing in close 
abundance at many places. 
Festuca capillata Lam. Common and well distributed, even 
far out on the plains and commons. 
Festuca ovina L. Abundant and widespread in dry sandy soils. 
Bromus tectorum L. Up to 1908 this grass had become estab- 
lished only sparingly, although growing freely on the low dunes 
near the bathing beach and observed at stations as far east as 
Polpis and Pocomo and west towards Madequet. In succeeding 
years it was found to be spreading freely and fast becoming com- 
mon. 
Bromus hordeaceus L. The prevailing grass in many lots and 
fields. 
Bromus secalinus L. Observed only at two stations in the 
town and in waste ground near Surfside.
