VOL. XVII. 



22. Quercus velutina. Rather common. 



23. Quercusjyalustris. Common. 



*24. Castanea dentafa. The most aliun- 



dant tree on higher grounds. 

 *25. Castanea pumila. AV>undant. 



*26. Junipemst Virginiana. Abundant.

 covering almost exchisively con- 

 siderable areas. 



The species marked with au asteiisk are not iiichided in any of the 

 western lists. Two of them (Nos. 9 and 25) did not assume tlie size and 

 scarcely the habit of trees, and ought, in fairness, to be omitted. 



(2) Bottoms of the Fafuxent River, Maryland, from Laurel 4 miles southward.

The above seemingly large list includes every species of tree which 

 I was able to recognize in any portion of the extensive area (at least 5 

 square miles), which included besides ordinary bottom land, swamps 

 and uplands, with varying conditions of soil. If the count had been 

 restricted to an area of say 100 acres, in any portion of the larger area, 

 the list would have been reduced about one-third. The district haviag 

 been carefully explored on very numerous occasions (much more thor- 

 oughly than I have been able to explore any western tract of equal 

 extent), it is probable that the list is very nearly complete.
