DESCRIPTION OF THE SPECIES. 325 



lobes; these latter sending off from near their base on the outer side two 

 strong branches, and tliese and the primaries higher up sending off slender 

 branches nearly at right angles that anastomose ; reticulation not seen. 



Locality : 72d mile-post, near Brooke ; only one specimen seen. 



This leaf also belongs to a comprehensive type, but does not combine 

 the features of so many different leaves as the preceding. It unites the 

 features of AmJkcphjllanu Hcdera, and Liriodendron. 



EUCALYPTOPHYLLUM, gen. nov. 



This genus contains onl}^ one species, whose character, owing to the 

 scantiness of material and the imperfection of the specimens, cannot be 

 further characterized than as having a near affinity with Eucalyptus. 



EuCALYPTOPHYLLUM OBLONGIFOLIUM, sp. nOV. 

 Plate CLXII, Fig. 4. 



Leaves small, oblong, base and summit not seen ; midnerve compara- 

 tively strong; lateral nerves very slender, crowded, going off obliquely, 

 flexuous, and branching copiously ; the ultimate branches form a closely 

 crowded reticulation, composed of elongate, subrhombic meshes, that stand 

 nearly at right angles with the midrib ; all the nerves are very slender. 



Locality: 72d mile-post, near Brooke; very rare. 



This leaf is something like Trisfania laurina, R. Brown. 



PHYLLITES Brongn. 

 Phyllites pachyphyllus, sp. nov. 



Plate CXLIX, Fig. 2. 



Leaf small, apparently spatulate in shape, flared out a little below the 

 middle, broad, and rounded at the summit, and gradually narrowed towards 

 tliebase; leaf-substance very thick; midnerve quite strong ; nervation not 

 seen. 



Locality: Fredericksburg; only one specimen found. 



Tiiis leaf shows no characters that can serve to place it in any par- 

 ticular jjenus.
