 angles very near its Inise, aerodrome, ruuniTig 

 close to and jiaraUel with the margins. Tor- 

 tiaries tliin, numerous, neai-ly straight, and 

 transverse. 



Tliis species, though it greatly resembles 

 some of the forms referred to Oinnamomum 

 lanceolatum (Unger) Heer,' is clearly distinct 

 and may be distmguished from this and aUicni 

 species of lanceolate Cuinamomums by tlie 

 lack of widening in the basal lamina. It is 

 represented in the succeeding Claiborne flora 

 by a closely allied, undescribed species, which 

 probably represents a dh'ect descendant and is 

 consistently narrower and more linear, with 

 supral)asilar lateral primaries and a somewhat 

 different and well-marked tertiary venation. 



Occurrence. — Lagrange formation (in l)eds of 

 Wilcox age), Puryear, Henry County, Teun. 

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

 sec. 28, T. 13 X., R. 12 W., De Soto Parish,

Description. — Leaves differing in size, lan- 

 ceolate in general outline, equally pointed at 

 the apex and the base. Length ranges from 8 

 to 13 centimeters. Maximum width, midway 

 between the apex and the base, ranges from 

 2.25 to 3.5 centimeters. Margijis entire, luii- 

 formly and regularly rounded. Texture coria- 

 ceous. Petiole not preserved. Midrib stout 

 and prominent. Lateral primaries nearly as 

 stout as the midrib, prominent, diverging from 

 its extreme base at angles of about 10°, aero- 

 drome about halfway between the midrib and 

 the marghis, and paralhd with the nrargins. 

 One or two camptodrome secondaries may be 

 developed in the extreme tip of the leaf. 

 Outer branches from the primaries diverge at 

 a wide angle and are rather straight and camp- 

 todrome. Midrib and primaries connected 

 by nearly straight, thhi transverse veins.

This species is represented by fragmentary 

 sjiecimens from tlie western embaymcMit area, 

 some of which were confused with Arctic or 

 European forms by HoUick. They resemble 

 ('iuiianioinum scheucJizari Heer and Dnplirw- 

 (jene I'anii Heer in a general way but are ])er- 

 fectly distinct, differing in general forni and 

 in the details of their venation. 



The present species is named from its ob- 

 vious filiation with the widespread Upi)er 

 Cretaceous species Cinnaniomu/n ncv'hcn'yi,- 

 of which abundant figures may l)e consulted 

 under the preoccupied name Cinnamomum in- 

 termedium NewbeiTV.^ 



Occurrence. — Wilcox group, Slaughter Pen 

 and ^'ineyard bluffs on Cross Bayou, Caddo 

 Parish, La. (collected by A. C. Veatch), and 

 Hardys MiU, Greene County, Ark. (collected 

 by r! E. CaU).

Description. — Lesquereux's description, ^^Tit- 

 ten in 1869, is as follows: 



(', foliis subcoraceis, ovatis. lauoeolatis, acuminatis, basi 

 in petiolo brevi, semipollioari longo, subdecurrentibus, inte- 

 gorrimis, triplinerviis, ner\-is lateralibus ultra 5 evanidis, 



Lesquereux described Cinnamomum ajfine in 

 the American Journal of Science for ISfiS with- 

 out figures and in 1SG9 he descril)ed and figured 

 Cinnamomum mississippiensis in the Transac- 

 tions of the American Philosophical Society. 

 Knowlton in 1898 united these two species, 

 but after detailed comparisons I believe that 

 they are distinct. Lesquereux had furnished 

 a figure of the southern form to Dana, who 

 ])ublishcd it in the first edition of his Manual 

 ill 1S66, so that the name inissl.s.Klppiensis must 

 ol>viously stand for the conil)ination in case 

 it should be discovered that mississippiensis 

 is simply a variant of affine. The species is 

 not common in tlui embayment region and is
