is a plant with bright yellow flowers {Hndsonia ericoides), while with 

 it we find associated the grayish patches of the reindeer moss {Cladonia 

 rangiferina), hair moss (Polytriclnim), goat's rue {Tephrosia virginiana), 

 extensive masses of trailing arbutus {Epigaea repens), and patches of 

 Anaphalis margaritacea (Fig. i). Clumps of the bayberry (Myrica 

 carolinensis) of a dark green color break the monotonous level of the 

 heath (Figs, i and 3). Patches of an irregular rounded form of the 

 huckleberry (GayJussacia resinosa) and sweet fern (Comptonia aspleni- 

 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 {Querciis 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 hsLyhevvy {Myrica carolinensis), sweet iern {Comptonia as pleni- 

 folia) and the low spreading carpets of the bearberry {Arctostaphylos
