LOWER EOCKXE FLORAS OF SOUTHEASTEKX NORTH AMERICA. 



(li^itinct with magnilication, is well marked and 

 typicaU}' laui'aceous. 



This species is not especially close to previ- 

 ously described species of either the North 

 American or the European Tertiar}-. It resem- 

 bles Oreodaphm mississippiensis Berry m its 

 ireneral appearance, undulate margins, and 

 areolatiou, as was noted in the discussion of 

 that species, but it is a shghtly smaller, more 

 synmietric leaf, and its specific differences have 

 ah'cady been enumerated. It is also similar 

 and of the same general type as Xectandra 

 lancifolia (Lescpiereux) Berry, but it is relatively 

 narrower, and the secondaries are more distant 

 and less regularly spaced. 



It resembles somewhat Persea palseomorplia, 

 described from Gelinden by Saporta and 

 Marion,' but is a more lanceolate form, and its 

 secondaries are thuiner, less regularly spaced, 

 and more ascending. It maj' be compared 

 witli numerous Miocene and still existmg spe- 

 cies, without, however, throwing any light on 

 its relations. Among some of the recent forms 

 with similar leaves are Goeppertia hirsuta Nees 

 of the mountains of Bolivia, Goeppertia ano- 

 mala Xees of Brazil, and OreodapTine Uanclieti, 

 also of Brazil. The most similar recent forms 

 are Nectandra patens Grisebach and Nectandra 

 Icrugii Mez of the West Indies. 



Occurrence. — Lagrange formation (in beds of 

 Wilcox age), 1\ miles east of Grand- Junction, 

 Hardeman Coimty, Tenn. (collected in 1904 by 

 Prof. L. C. Glenn, for whom the species is 

 named). 



Collection.. — U. S. National Museum. 



Nectandra pueyearensis Berry, a. sp. 

 Plate CV, fi,2:ure 2. 



Description. — Leaves of relatively great 

 length, oblong-lanceolate and somewhat falcate 

 in general outline, gradually narrowed distad 

 to the bluntly pointed and slightly emarginate 

 tip and somewhat more abruptly narrowed to 

 the narrowly cuneate base. Length about 18.5 

 centimeters. Maximum width, midway be- 

 tween the apex and the base, about 3.3 centi- 

 meters. Margins entire, very slightly undu- 

 late. Texture coriaceous. Petiole not pre- 

 served. Midrib rather stout, becoming thin 

 distad, very prominent on tlio lower surface of 

 the leaf. Secondaries relatively thin but prom-

inent: about 1.5 mostly ulternate pail's diverge 

 from the midrib at angles of about 45°, curving 

 regiilai"ly upward, (-amptodrome. Tertiaries 

 form a t>"])icaUy lauraceous areolation, not 

 well shown in the specimen figured, which 

 shows the upper surface of a leaf on which the 

 areolation is very faint. 



This fine species is well differentiated from 

 the other Wilcox Lauraceap, among wliieh it 

 shows resemblances to Oreodaphne mississip- 

 piensis Berry, a form, however, that is rela- 

 tively wider and less elongated, somewhat , 

 narrowed distad and that has a wider midrib 

 and fewer more asceiicHng seconihiries. Nec- 

 tandra punjearensis has somewhat the propor- 

 tions of Mespilodapline eolignitica (Hollick) 

 Berry, but that form is somewhat smaller and 

 more coai"sely vemed and the secondaries are 

 wider spaced and more curved. Compared 

 with the other Wilcox species of Nectandra, it 

 is much larger and more oblong than either 

 Nectandra pseudocoriacea Berry or Nectandra 

 lowii Berry. It is narrower and much more 

 elongated than the broad-leafed acuminate 

 Nectandra gleuni Berry or Nectandra lancifolia 

 (Lescjuereux) Berry, which have thinner, more 

 numerous, and less ascendmg secondaries. It 

 shows some sunilarity to Laurus ocoteoides 

 Lesquereux,^ a rare species of the Denver for- 

 mation of Colorado, and greatly resembles 

 several European Tertiary forms referred to 

 Laurus. It may be matched by material of 

 the existing South American forms of Oreo- 

 daphne, Mespilodaphne, and Nectandra. 



Occurrence. — Lagrange formation (in beds 

 of Wilcox age), Puryear, Henry County, Tenn. 

 (collected by E. W. Berry). Wilcox group, 2f 

 miles southeast and 2 miles south of Na])orton, 

 De Soto Parish, La. (collected by O. B. Hop- 

 kins). 



Collection. — U. S. National Museum. 



Nectandra lowii Berry, n. sp. 



Plate LXXXVIII, figures 4 and 5. 



Description. — Leaves medium sized, lanceo- 

 late in generjxl outhne. Length about 10 cen- 

 timeters. Maximum width, about halfway 

 between the apex and the base, about 2 centi- 

 motei-s. Apex narrowed, acuminate. Base 

 ahnost equally narrowed and acuminate, the 

 basal margins being slightly fuller than the
