DESCRIPTION OF THE SPECIES. 295 



FlCUS VlRGINIENSIS, S[). IIOV. 

 Plato CXLIII, Figs. 1,3; Tlato CXUV, Fig. 1. 



Leaves small, elongate-oblong, obtuse, gradually narrowed towards 

 the base into the petiole, so as to form a long, narrow wing along the 

 petiole ; midrib distinct to the sunnnit ; lateral nerves slender, but very 

 sharply defined, making a large angle with the petiole and going off at reg- 

 ular and equal intervals, opposite or subopposite, arching over in a flex- 

 uous manner to unite with those next above, forming a series of well-defined 

 arches not fnr from the niiirgin ; branches on the outer side from the arches 

 form a flexuous nerve, which runs parallel \\ith and near to the margin, and 

 wliich, by sending branches to the principal arches, forms a series of subor- 

 dinate ones ; branches sent off from the primaries and from the midrib 

 unite under lai'ge angles to make a series of meshes irregular in size and 

 polygonal in form ; these are filled by the ultimate reticulation, which is. 

 as are all the nerves, sharply defined. 



Locality : Fredericksburg ; rare. 



This plant, in shape of leaf and nervation, is like some forms of Siipi)i- 

 dus. It is much like Lesquereux's Ficus laurophjlla,^ but tlie primary 

 nerves are not so strong and the arches are more pronounced. 



Ficus Fkedericksburgensis, sj). nov. 



Plato C'XLVIII, Fi};s. 3, 5. 



Leaves of medium size, oblong or elliptical, subacute ; midnerve very 

 strong; primary nerves rather strong, leaving the midnerve alternately at 

 an angle of about 45°, at regular and nearly equal intervals, arching back- 

 wards and then forwards until near the margin, where they bend abruptly 

 forwards, forming arches by union with the primaries next above ; I'eticula- 

 tion not seen. 



Locality : Fredericksburg ; I'are. 



The plant is a good deal like Sapindopsis elliptica, but the nervation is 

 stronger, and tlie leaves are larger.
