aries stout, prominent; seven or eight alternate pairs diverge from 

 the midrib at angles of about 45°, sweep upward in long ascending 

 curves, and are camptodrome in the marginal region. Tertiaries 

 comprise arches along the margins and prevailingly percurrent veins 

 between the secondaries. 



This exceedingly well-marked species is named for the collector, 

 Dr. Wendell P. Woodring. It is most remarkably like the existing 

 Nectandra antillana Meissner, a common woodland and river bank 

 form throughout both the Greater and Lesser Antilles. A nature 

 print of a leaf of the latter is introduced beside that of the fossil 

 species for comparison. I have not searched herbaria to determine 

 whether Nectandra antillana occurs on the mainland of Central 

 America nor whether there are similar leafed Nectandras in the 

 existing flora of Costa Kica, but presumably such is the case. 



Among fossil forms the present Costa Rican species stands nearest 

 to Nectandra antiManafolia Berry MSS., a rather common form of 

 the Jackson Eocene deposits of Texas. It is also similar to two 

 closely related species of the Wilcox Eocene of the Mississippi embay- 

 ment region, namely, Nectandra lancifolia (Lesquereux) Berry 5 and 

 Nectandra glenni Berry. 6

Description. — It has been impossible to determine the botanical 

 affinity of this very characteristic small leaf. It may be described 

 as follows: Outline broadly spatulate, widest above the middle, with 

 a rounded tip and a broad sessile sheathing base. Margins full and 

 entire. Texture subcoriaceous. Length, about 5.5 cm. Maximum 

 width, about 2.5 cm. Midrib extremely stout and prominent, ex- 

 panded and flattened at the base. Secondaries subopposite, stout, 

 numerous, and ascending except in the narrowed base, camptodrome. 

 Tertiaries thin, but well marked, percurrent. 



This form invites comparisons with a variety of recent forms. In 

 the prominent venation it suggests a juvenile leaf or one in proximity 

 to flowers. It is well marked and easily recognized, and should 

 prove useful for purposes of correlation if subsequent collections are 

 made. It suggests the family Moraceae to me, but I do not feel at 

 all certain on this point.
