The species is represented in tlio lower 

 Eocene of the Rocky Monntain region, where it 

 occure as far south as New Mexico. 



Occurrence. — Ackerinan formation, Ivaglaiids 

 Branch, Lafayette County, Miss, (.collected by 

 E. V\ . Hilgard). Dana gives a locality in ^Vin- 

 ston County, Miss., at Colemans Mill near New 

 Prospect, now in Choctaw County. At this lo-

 corded, was made by llilgard.

Description. — This sp(>cii-s has tdi'cady ])een 

 described from the Midway ( ?) of Texas, (.See 

 p. 13.) It is common in the Wilcox of the 

 western Gulf area but has not been observed 

 in the eastern Gulf area. The material is 

 identical with that described by Lcsquoroux 

 from the Denver formation of the Ivocky 

 Mountain province. 



Occurrence. — Old Port Caddo Landing, on 

 Little Cypress Bayou, Cross Lake, Harrison 

 County, Tex. (collected by T. W. Vau.ghan) ; sec.

Bescriptinn. — Leaves oblong - elli))lic:il oi- 

 obovate in outline, the tip al)ruptly narrowed 

 and apiculato and tlie base gradually narrowed 

 and cuneate. Length of Wilcox forms about 

 I-'! centimeters. Maximmn width, midwav 

 bolweon the apex and tin- t)aso, about 4.2.5 

 centimeters. ]\Iargins enlirc, full aiul rounded, 

 recurved to form tlio slender extended acumi- 

 nate tip. Texture sul)coriaceous. Primaries 

 three, suprabasilar, the midrib stoutest: the 

 laterals diverge suboppositoly at acute angles, 

 pursuing a course that is but slightly curved, 

 joining outward branches from the lowermost 

 secondary on each side in tlie upper haK of the 

 leaf. Secondaries, two or tln-eo alternate curved 

 camptodrome pairs in the upper half of tlie 

 leaf, diverging from the midrib at wide andes. 



This species is a type that approaches close 

 to three supposedly different European Tertiary 

 species — Cinnamomum bucMi Heer, Cinnamo- 

 mum polymorphum Heer, and Cinnamomum 

 spectahile'Reer — especially to the first and last of 

 these three. It is also similar to certain Euro- 

 pean forms referred to Daplinogene,for example 

 Daplmogene amplior Saporta' from the Sannoi- 

 sian of Aix. On the whole the form from Loui- 

 siana can not be separated from Ci7inamomum 

 bucMi, although it is somewhat larger and its 

 coarser venation suggests Cinnamomum specta- 

 hile. Both are mainly Aquitanian species, 

 although Cinnamomum. Imclm is found as low 

 as the Bartonian in Italy and Cinnamomum 

 spectahile has been identified by Knowlton from 

 the Fort Union beds in Yellow^stone Park. In 

 the absence of the upper half of the leaf 

 Cinnamomum hucliii can not be distinguished 

 from a large variety of triple-veined lauraceous 

 forms. It does not aj)p(>ar to have been com- 

 mon in the Wilcox ilora; at least if it was it 

 has not been preserved in large numbers.
