Cumberland Hills. 



Following the road toward Cumberland, after crossing the west 

 valley, there is a hill known as Martin Mountain, upon the slope 

 of which there is an outcrop of limestone. In the vicinity of this 

 outcrop, the following species were noted : 



Pellaea atroparpurca 

 Camptosorus rhizophyllus 

 Saxifraga virginica 

 Aquilegia canadensis 

 Hydrangea arborescens 

 Acer saccharinum 

 Cercis canadensis 

 Woodsia obtusa 

 Campanula americana 

 Anemone virginiana 

 Allium cernuum 

 Asimina triloba 

 Acer saccharum 

 Sanguinaria canadensis. 



On account of the steepness of many of the stream valleys, the 

 lower portion of the slopes are often clamp and support a luxuriant 

 vegetation, but the species present are not often of conspicuous dif- 

 ference from those of the somewhat dryer but otherwise similar 

 habitats. The differences in the humidity are often shown in the 

 development of the lower forms, like the Liverworts, Mosses, and 

 damp soil Algae, especially of the blue-green group. Of the higher 

 forms the low and moist places show such plants as Spathyema, 

 Veratrum and Sagittaria or Alisma, although none of these are as 

 common as in the localities at less elevations. 



Between Martin Mountain and Cumberland there is but little of 

 note: the region is a rolling one, with the more gentle slopes and 

 the uplands tilled, the steeper slopes and the steep valleys in general 

 left in forest. The rugged character of the country encourages the 

 washing of the roadsides by the rains, and thus there is less of that 

 tvpe of vegetation through this territory than was the case to the 

 east of Sideling Hill. As in the region discussed in connection with
