LOWER EOCEXE FLORAS OF SOUTHEASTERN NORTH AMERICA. 



better material is found the plant will pri)l)ably 

 be referred to another genus. jUthough no 

 new material has been obtained in subsequent 

 colleeiions, I have ventured to transfer this 

 form to tlie genus Eugenia, with which in my 

 judgment it shows the greatest affinity. It is 

 much narrower and more elongated than the 

 associated Eugenia liilgardiana Berry. Other 

 Wilcox plants which resemble the present spe- 

 cies are Sapindus linearifolius Berry and Mijr- 

 cia bentonensis Beny. Both are somewhat 

 larger and differ decidedly in their venation 

 characters. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), Somerville, Fayette County, Tenn. 

 (collected by J. M. Safford). 



CoUedioii. — Location of type unknown. 



Eugenia hilgardiana Berry, n. sp.

Sapindm undulalus Alexander Braun. Lesquereux, 

 Am. Philos. Soc. Trans., vol. 13, p. 420, pi. 22, 

 fig. 6, 1869. 



Description. — Leaves small, ovate-lanceolate 

 in outline, the apex narrowed and blmitly 

 pomted and the base ratlier narrow and cune- 

 ate. Length about 4 centimeters. Maximum 

 width, in the lower half of the leaf, about 1.5 

 centimeters. Margins entire, slightly wavy 

 and markedly revolute. Texture very thick 

 and coriaceous. Petiole if present very stout, 

 not preserved. Midrib extremely stout, curved, 

 prominent on the lower surface. Secondaries 

 rather stout, thin compared with the midrib, 

 more or less immersed in the thick leaf sub- 

 stance; five or six subopposite pairs diverge 

 from the midrib at acute angles of about 30°, 

 pursuing a nearly straight ascending course, 

 subparaUel, the lower pairs parallel with the 

 lower margins of the leaf, all curving approxi- 

 mately parallel with the lateral margins toward 

 tlieir camptodrome tips. 



This species is based on the single specimen 

 collected by Prof. Hilgard half a century ago 

 and identified by Lesquereux with Sapindus 

 undukitus Alexander Braun, with which it has 

 practically nothing in common. The illustra- 

 tion of the type specimen given in Plate XC, 

 figure 6, brings out its true character and shows 

 its thick form and revolute margins. It is 

 named in honor of E. W. Hilgard, the veteran 

 southern geologist who did sucli a large amount 

 of most excellent and lasting pioneer work on 



the geology of our Southern States. The genus 

 was named by Linne in commemoration of 

 Prince Eugene of Savoy, an early patron of 

 botany, and by an unmtentional combination 

 serves also to commemorate the Christian name 

 of tiie geologist to whom the present species is 

 dedicated. 



Eugenia liilgardiana can scarcely be distin- 

 guished from some of the leaves of three of the 

 existing species that reach southern Florida — 

 Eugenia axillaris WiUdenow, Eugenia rhombea 

 Krug and Urban, and Eugenia confusa De Can- 

 doUe, all coastal tropical forms. 



The genus comprises several hundred exist- 

 ing species (about 500 accordmg to Sargent) 

 and is common in the Tropics of both the East- 

 ern and Western hemispheres, Avith littoral 

 species in both regions. 



Occurrence. — Ackerman formation. Hurleys, 

 Benton County (formerly part of Tijijiah 

 Comity), Miss, (collected by E. W. Hilgard). 



Collection. — U. S. National Museum. 



Eugenia pueyearensis Berry, n. sp. 



Plate XC, figures 11 and 12. 



Description. — Leaves small, eUiptical-ovatc 

 and somewhat inequilateral in general out- 

 line, sessile, widest near the middle and 

 tapering about equally distad and proximad. 

 Tip bluntly pointed. Base broadly cuneate. 

 Length about 2 centimeters. Maximum width 

 about 11.0 millimeters; the lamina on one side 

 of the midrib at least 2 milUmeters wider than 

 that on the opposite side. Midrib extremely 

 stout and prominent at the base, longitudinally 

 striated, 1.5 to 2 miUimeters in diameter, taper- 

 ing rapidly upward imtil it is not at all promi- 

 nent and scarcely discernible in the tip. Mar- 

 gins entu-e and fuU, especially on the broader 

 side of the lamina. Texture very coriaceous. 

 Secondaries and tortiaries entirely immersed in 

 the thick substance of the leaf. 



This smaU-leafed species is well character- 

 ized and is apparently referaVde to the genus 

 Eugenia. Among the other Wilcox species of 

 Eugenia it shows considerable resemblance to 

 Eugenia hilgardiana Berry but differs in its 

 less elongate form and smaller size and in lack- 

 ing the prominent ascending seconchirics of that 

 species. It comes from a higher horizon in the 

 Wilcox than Eugenia liilgardiana, and hke it 

 seems to l)e of rare occuiTence.
