and Juncus roemerianus prevail. The abundance of Loblolly Pirn:' 

 here is partly cine to proximity to its center of distribution. 



Of a still different type are the rather precipitous small islands 

 in Rhode River, Anne Arundel County. On these the arboreal 

 growth is abundant and varied with oaks dominating. Besides the 

 more common oaks (Quercus velutina, Quercus digitata and Quercus 

 alba) Quercus michauxii is found here. This species occurs also 

 on the adjacent mainland. Other trees found on the higher parts 

 of these islands are: hickories, Ash, Red Maple, Dogwood, Huckle- 

 berry, Sweet Gum, Beech, Scrub Pine, with thickets of Smilax. 

 These islands seem to be fragments of the mainland cut off by the 

 wave action which is much in evidence in this vicinity. Hence one 

 is not surprised to find vegetation similar to that on the mainland 

 but lacking in a few species which find the exposed conditions too 

 trying. 



PLANTS OE CULTIVATED GROUND. 



This title is used in a broad sense, to include the vegetation of all 

 areas which have been frequently disturbed by man. 



Roadsides. — In many parts of the district these are given scant 

 attention, and hence are well supplied with trees of quick-growing 

 habit, the kinds depending on the nature of the adjacent forests. 

 In Idealities where the roads are better cared for, certain trees are 

 left on account of their value for fruit or shade and may reach a 

 great size. Owing to the ease with which Scrub Pine distributes its 

 .seed, and the capability it possesses of enduring insolation, it readily 

 establishes itself along roadsides. The Red Cedar has been planted 

 by birds so extensively along fences that in some localities living 

 fence posts have come to replace the old decayed ones. This tree 

 occurs in two rather distinct forms, one a tall spindle shaped tree, 

 almost as slender as a Lombardy poplar, the other a much broader 

 rounder tree. The two forms occur in different sections of the state, 

 but just what determines the difference in form remains to be found 

 cut. Taxcmomists do not recognize any varietal difference; possibly 

 it is merely a difference in age, the round form being older. The 

 next commonest tree of roadsides, especially towards the coast, is
