Moissner, a common form of ( lio woods and i-ivor 

 banks throiighout the West Indies. Other West 

 Indian species of Nectandra are also very 

 similar. 



The forms from Hurleys, Miss., that Les- 

 quereux referred to the Arctic Tertiary slK^cies 

 Quercus lijeliil I leer, arc not tliat spetdes, but 

 two of Lesfjuei-eux's figunnl specimens are 

 probably referable to this species, although tlie 

 type material is lost-. His Plate X VH, figure 1 , 

 shows a specimen somewhat smaller and 

 slightly narrower and the secondaries are less 

 ascending, but the general form, charactw- of 

 the base, and the arcliing of the secondaries 

 close to the slightly midulating margin serve to 

 identify it with Nrefandra lancifolia. Tiie sin- 

 gle form described by Lesquereux from Somer- 

 viUe, Tenn., as Laurus carolinensis Michaux, 

 wliich was thought to be of Pleistocene age 

 and afterward referred to Quercus Itjellii, is 

 also not that species. It is only a fragment 

 and the specimen is lost, but it is probably a 

 fragment of Nectamlra lancijolia, although the 

 base is less sharply pointed. 



A specmien of this species in the National 

 Museum (No. 2578) from Campbell's quarry, 

 Caddo Parish, La., was identified by Les- 

 (juereux as Bhamnus erklani Unger, from wliich 

 it is jiei-fectly distmct. 



Nectandra lancifolia is represented by a 

 closely related form in the lower Claiborne of 

 ^Vrkansas, which will be described as Nectmulra 

 arTcansana. It differs from this Wilcox species 

 in its sliglitly smaller size, fewer secondaries, 

 and longer petiole. 



Nectandra lancifolia is present, according to 

 Knowlton, in the lower Eocene flora of the 

 Raton coal field in New Mexico. 



Among homotaxial foreign forms it is closely 

 comparable to Laurus excellcns described by 

 Watelet ' from the Ypresian of the Paris 

 Basin.

Nectandra glenni Berry, n. sp. 



Plate I.XXXV, figure 1. 



Description. — Rather large and symmetric 

 leaves, lanceolate in general outline, the tips 

 and bases about ecjually pomted. Length 

 about 16 centimeters. Maximum width, which 

 is near the midtile of the leaf, about 3.9 centi- 

 meters. Margms entire but slightly undulate. 

 Petiole stout and curved, slightly more than 2 

 centimeters- in length. Midrib curved, less 

 stout than in Orcodaplme missis.<>i'p'piensis 

 Berry ; the vascular bundles of which it is com- 

 posed show as longitudinal stria- on tlie impres- 

 sions of tlie fossil. Secondaries remote, some- 

 what irregularly spaced, opposite to alternate, 

 camptodrome. The lowest pair are of smaller 

 caUber than the others and spring from the top 

 of the petiole, fomimg a margmal hem along the 

 lower lateral leaf margins. The next pair 

 diverge from the midrib at angles of about 30° 

 2 centimeters above the base, pursue at first a 

 straight course, and ultimately curve upward 

 parallel with the margin, along wliich they arch. 

 They are stronger than the basal pair but less 

 stout than the third subopposite paii', which 

 leave the midrib 3.5 centuneters above the base 

 at angles of about 30° and sweep U|)ward in 

 broad, gentle curves, becoming parallel witli the 

 margins, along which they arcli for a long dis- 

 tance. This is the stoutest pair of seconda- 

 ries; the difference in caliber is, however, slight, 

 and were it not for the interval which thc}^ sub- 

 tend would scarcely be noticed. The interval 

 to the next secondaries is 3.5 to 4 centimeters, 

 and the remaining four or five pairs of alter- 

 nate secondaries brancii from the midrib at 

 angles of 40° to 45°, passing upward in regular 

 subparallel cm"ves. Tlie tcu'tiaric^s are fuic and 

 mostly percurrent, though a few slight varia- 

 tions are sliown neaf the riglil-liand margin of 

 the specimens figured. Tlie areolation, only
