Bauhinia gigantea Newb. 



Bauhinia ? gigantea Newb., Fl. Amboy Clays, 93, pi. 20, f. i, 

 1896. 



Description. — Leaves of immense size for this genus, appar- 

 ently very similar to the preceding in general appearance, but 

 about 20 cm. in diameter. Lobes deeply cleft, more so than in 

 Bauhinia cretacea, and possibly reaching quite to the base. The 

 single nearly complete lobe collected is oblong, unsymmetrical in 

 outline, 20 cm. long by 7 cm. to 8 cm. in width, with an almost 

 straight inner margin. Apex obtuse. The venation is stout, the 

 principal vein starting at the basal inner margin runs almost 

 straight to the apex, dividing the lobe in the ratio of about i to 

 5, it gives off three camptodroine secondaries internally, the lowest 

 of which branches slightly below the middle of the lobe. 

 Externally there are six approximately equidistant and parallel 

 camptodrome secondaries decreasing regularly in size from the 

 base upward. 



Only two specimens O'f this species have been discovered, the 

 more complete one being the single lobe which Prof. Newberry 

 figured. However, there can be no* question as to its generic re- 

 lations. It is very similar to the preceding species, but may be 

 distinguished by its much larger size, more deeply cut lobes, 

 undulate outer margin and by the details O'f venation, one feature 

 of which is the marked unsymmietrical position of the principal 

 vein. 



Occurrence. — Woodbridge.
