Order ROSALES. 

 Family MIMOSACEAE. 



Genus INGA Willdenow. 



INGA SHERQLIENSIS, new species. 



Plate 25, fig. 2. 



Description. — Leaflets ovate and somewhat falcate, markedly 

 inequilateral in outline, particularly proximad. Apex acute. Mar- 

 gins entire. Texture subcoriaceous. Length, about 6.5 cm. Max- 

 imum width, about 2.25 cm. Petiolule stout, about 6 mm. in length. 

 Midrib curved, stout, and prominent. Secondaries thin, numerous, 

 subparallel, and camptodrome. Tertiaries subparallel with seconda- 

 ries, close set, connected by fine cross nervilles to form a close areo- 

 lation. 



This is a well-marked species of Inga, clearly differentiated from 

 previously described fossil forms but showing considerable resem- 

 blance, particularly in the venation, to Inga reissi described by 

 Engelhardt 2 from the Tertiary (probably Miocene) of Santa Ana in 

 Colombia. The latter is, however, a somewhat more ovate and more 

 nearly equilateral leaflet. 



Several existing species show close similarities to the fossil. 



Holotype.— Cat. No. 35466, U.S.N.M. 



Order GERANIALES. 

 Family EUPHORBIACEAE. 



Genus HIERONYMIA Allen. 



HIERONYMIA LEHMANNI Engelhardt (?).

 Abh. Senck. Naturf. Gesell., vol. 19, p. 11, pi. 2, figs. 1, 2, 1895.— Berry, 

 U. S. Nat. Mus., Bull. 103, p. 36, pi. 16, fig. 3, 1918. 



Description. — Leaves broadly elliptical or somewhat deltoid and 

 inequilateral in outline, with a shortly acuminate tip and broadly 

 rounded full lower lateral margins and a very wide, somewhat ob- 

 liquely truncated base. Length, about 12 cm. Maximum width, in 

 the lower half of the leaf, about 10 cm. Margins entire, full, and 

 rounded. Texture thin but coriaceous. Midrib stout, curved, prom- 

 inent on the lower surface of the leaf. Secondaries stout, 10 or 11 

 irregularly spaced pairs, prominent on the lower surface of the leaf; 

 they diverge from the midrib at wide angles which become more 

 acute in the apical part of the leaf; those on the narrower side are 

 more ascending and somewhat straighter than those on the wide side; 

 all are conspicuously camptodrome at some distance from the margin.
