(Sp. PL, 1753, P- 202.) 



Hedera obliqua, Newb. 



Hcdera obliqua Newb., Fl. An.boy Clays, 113, pi. 3/, f. 8; pi. 

 38, f. 5, 1896. 



Description. — Leaves large, obliquely elliptical in outline, 

 markedly uns>Tnmetrical, 9 cm. to 15 cm. in length by 8 cm. to 11 

 cm. in width. Margins somewhat undulate, especially distad. 

 Petiole stout, 2.3 cm. or more in length. Apex broadly rounded 

 or emarginate. Base rounded or truncate. Primaries 5 or 

 more, palmate, diverging at acute angles from the top of the 

 thickened petiole, the midrib the stoutest ; the balance fork or 

 soon curve to join branches from the midrib, forming a somewhat 

 irregular and open network of camptodrome arches. 



This species may be nothing more than a variant of Hedera 

 primordialis Saporta, which it greatly resembles, since it is much 

 less abundant. It is, however, generally larger in size, strikingly 

 unsymmetrical and lacks the cordate base of that species. It is 

 confined to the Woodbridge locality. 



Occurrence. — Woodbridge.
