The herbaceous vegetation is much the same as that which has 

 already been listed for the Clay Upland forests, and like it is poor 

 in individuals. 



Throughout the greater part of Caroline and Queen Anne's coun- 

 ties the Scrub Pine is more conspicuous than the Loblolly in the 

 first stage of reforestation, and there are many stands of Scrub 

 Pine north of Denton and Greensborough, that is, within the de- 

 ciduous forest area, but these are all destined to become replaced 

 by purely deciduous forest in the course of time. 



Deciduous Upland Forest. — The Deciduous Upland Forests of 

 the AVicomico formation in Queen Anne's, Kent and southern Cecil 

 counties are made up in part of the same species which accompany 

 the pines in the coniferous forest of the lower counties, but a few 

 new species are encountered here, such as are of much greater 

 abundance in the Midland Zone, and a few species which are quite 

 rare in the lower counties now become important constituents of 

 the forest. The most noticeable addition to the forest flora is the 

 Chestnut, and the most noticeable change in relative abundance 

 is that which brings the Hickories to the fore as very important 

 constituents of the oldest stands of forest. 



In a grove about 40 years old three miles west of Chestertown, 

 Kent County, the Mocker-nut Hickory, the Pig-nut Hickory and 

 the Bitter-nut Hickory formed 55% of the forest stand, the Black 

 Oak 20%, the Spanish Oak 10% and the Willow Oak, the Sweet 

 Gum and the Black Gum 5% each. A second stand was examined 

 near Schenk Corners, Queen Anne's County, in which the Hick- 

 ories did not predominate, the percentage of the various trees being 

 as follows :
