is a plant with bright yellow flowers (Hudsonia ericoides), while with 
it we find associated the grayish patches of the reindeer moss (Cladonta 
rangiferina), hair moss (Polytrichum), goat’s rue (Tephrosia virginiana), 
extensive masses of trailing arbutus (Epigaea repens), and patches of 
Anaphalis margaritacea (Fig. 1). Clumps of the bayberry (Myrica 
carolinensis) of a dark green color break the monotonous level of the 
heath (Figs. 1 and 3). Patches of an irregular rounded form of the 
huckleberry (Gaylussacia resinosa) and sweet fern (Comptonia asplent- 
folia) are common. A few other flowering plants relieve the flat

Some parts of Nantucket, notably the southeastern, are covered 
by two low oaks, namely, the bear oak (Quercus nana) (Fig. 2), and

Nantucket and in central Marthas Vineyard, this growth of oaks 
and associated plants suggests the dwarf elfin wood, or chaparral, of 
the California coast. The other constituents of these low oak thickets 
are the bayberry (Myrica carolinensis), sweet fern (Comptonia asplent- 
folia) and the low spreading carpets of the bearberry (Arctostaphylos
