DESCRIPTION OF THE SPECIES. 201 



Nageiopsis acuminata, sp. IIOV. 



Plat.^ LXXXV, Fig. 11. 



Leaves narrowly ovate, widest at base and slightly acuminate, abruptly 

 rounded off at base and attached by a short strong pedicel, graduallA' nar- 

 rowed towards tips ; nerves not seen. 



Locality : Near Telegraph Station ; very rare. 



Only one good specimen seen. It shows a small bit of the stem still 

 attached. As no large amount of material was obtained at this place the 

 rarity of the plant may be apparent rather than real. It is possible tliat 

 the plant may be a Zamites. 



Nageiopsis heterophylla, sp. nov. 



Pliite LXXXIV, Fig. t; Plate LXXXVI, Figs, (i, 7; Plate LXXXVIII, Figs. 2, 5. 



Stems large, branching freely ; leaves small, narrowly ovate to oblong- 

 linear, widest near the base and usually ratlier abruptly rounded off there, 

 attached by a very short slightly twisted pedicel, gradually narrowed to 

 acute tips ; leaves sometimes vai-ying irregularly in size, larger and smaller 

 ones being intermingled or placed on opposite sides of the stem ; leafy 

 branches terminating in a leaf similar to the lower ones ; nerves forking 

 once or twice near the base of the leaves, then parallel to near the sum- 

 mit, where they are more approximate, the outer ones ending in the mar- 

 gins below the summit. 



Localities : Fredericksburg ; lishiiig hut above Dutch Gap Canal. 



This pretty little plant is not uncommon at Fredericksburg. It shows 

 the peculiar feature (as in PI. LXXXVI, Fig. 7, and PI. LXXXVIII, 

 Fig. 2) of having the leaves at tiie bases of the twigs very unequal on 

 opposite sides, and also, as in the first-named figure, the peculiarity of hav- 

 ing small leaves intermingled with large ones. In PI. LXXXIV, Fig. 4, 

 the tips of the leaves have been removed by accidents of preservation. 



Nageiopsis microphylla, sp. nov. 



Plate LXXXIV, Fig. 0; Plate LXXXV, Fig. 14: Plate LXXXVI, Fig.s. 1-3, 5. 



Leafy twigs piimately arranged, terminating in a leaf larger than 

 those lower down ; leaves very small, narrowed to the base and apex, ellip-
