272 THE POTOMAC OR TOUNGEE MESOZOIO FLOEA. 



Ament of angiosperm ?, sp. I 



Plate CXXXV, Fig. 16. 



This may have been the pollen-bearing catkin of some unknown 

 Angiosperm. As only one specimen was found, and it was very imper- 

 fectly preserved, nothing definite can be said as to its true place. 



Locality : Fishing hut above Dutch Gap Canal. 



Fruit capsules, sp. ? 



Plate CXXXV, Fig. 14. 



This figure shows two capsules of some fruit apparently united at 

 base and borne on a short pedicel. They are elongate-elliptical in shape, 

 having at the summit tooth-like projections, as if due to incipient dehis- 

 cence. 



Locality : Occurs in only one species, at the fishing hut above Dutch 



Gap Canal 



Cone of callitris ? sp. ? 



Plate CLXIX, Fig. 8. 



This fossil, which appears to be nearer Callitris than any other, seems 

 to be a broadly oblong cone, truncate at the summit. It is attached by a 

 very stout pedicel to a thick twig, and appears to be split into several 

 portions, which are narrowly oblong. 



Locality: It was found in only one specimen, at the fishing hut above 



Dutch Gap Canal. 



Seed of pinus !, sp. I 



Plate CLXX, Fig. 4. 



The figure represents what seems to be a seed of Pinus. It is of 

 small size, elliptical in form, and has attached to it a large scale. 



Locality : One specimen only found at Covington street, Baltimore. 



Pollen sacs ?. 



Plate CXXXVI, Fig. 7. 



Fig. 7 gives a number of small capsules, natural size, grouj^ed in a 

 radiate manner, that resemble the pollen sacs of Taxus. They may belong 

 to Athrotaxopsis. 



Locality: A single specimen found at the 72d mile-post.
