roun(l(Hl apex is abnormal tlic base is surely 

 normal, anil this as well as the character of the 

 venation diflfers from the known memljers of 

 this flora, so that I am constrained to describe 

 it as a new species. 



Occurrence. — Holly Springs sand, HoUy 

 Sprhigs, Marshall County, Miss, (collected by

Description . — Leaves eUi])tical to ovate-lance- 

 olate in outline, somewhat variable in j^ropor- 

 tions and size, ranging from 4 to 8 centimeters 

 in length and from 1..5 to 2.8 centimeters 

 in maximum widtii about midway between 

 the apex and the base. In the typical forms 

 the apex and base are identical hi size and 

 shape and are Ijroadly pointeti by the coming 

 together of the full rounded lateral margins, 

 the leaves being strictly equilateral. There 

 is a tendency in some specimens, like tliose 

 figured from Oxford, Miss., and Puryear, 

 Tenn., for tlie leaves to assume a narrower 

 form, the apex being narrowed as compared 

 with the broad base, somewhat elongated and 

 acuminate, and these leaves are slightly falcate. 

 Tlie leaves were evergreen and coriaceous, and 

 the margins were entire. Petiole short and 

 stout, 3 to 5 millimeters in length, tlie average 

 being about 4 millimeters, curved, and in 

 some specimens 1..5 millimeters in diameter. 

 There is a slight decurrence of the extreme 

 basal margins on tlie petiole. The midrib is 

 rather stout, considerably thinner than the 

 petiole, generally straiglit. The lateial prima- 

 ries are thinner than tlie midrib, from which 

 they branch at or near the extreme base at 

 angles of about .'30°, regularly l)owed and aero- 

 drome, reuniting with the midrib at its extr(>me 

 tip at the same or slightly more acute angles 

 than their divergence angl(>s. Outside the 

 mahi primaries tliere is a single accessory pri- 

 mary on each side of the leaf. These acces- 

 sory primaries diverge from the top of tiie 

 petiole at slightly wid(>r angles tlian the main 

 primaries aiul run parallel witii them and also 

 with the leaf margin, pursuing a course close 

 to the margin; in some specimens they consti- 

 tute a marginal heju and in others are distant 

 fr.)m the margin as nuich as 1.5 millimeters. 

 Tertiaries line, numerous, and obliijuely trans- 



verse, both between midrib and mam prima- 

 ries and tile main and accessory primaries. 

 In no specimens are secondaries developed of 

 thi> type found in the distal part of most sj)ecies 

 of Cinnamomum, nor are tliere any marginal 

 upwardly dir(>ct(nl and camptodrome tertiaries 

 as in most species of Ciiinamomuni. 



This is an unusually weU marked species 

 and unlike any previously described fossil 

 species, although identical with several (exist- 

 ing species. Species of Chuiamonium are 

 aJmndant from the middle Cretaceous to the 

 jiresenl. The leaves arc always rather va- 

 riable, as the reader can see by consulting 

 the figures of the widespread Tertiary species 

 C'innamominn hiicliiilieer, 0. sclieuchzeri Heer, 

 C. rosfiindssleri Heer, C. polymorphum Heer, 

 and C. lanceolatum Heer. Leaves of the types 

 of these species are recorded from numerous 

 American, European, and some Asiatic locali- 

 ties at horizons ranging from the base of the 

 Eocene through the Pliocene. They are fig- 

 ured by Pleer ' and by numerous other authors. 

 It is possible to find smgle variants among 

 Heer's species, as well as among the fifty or 

 more additional fossil species, that closely 

 resemble Cinnamamum vera, but none are 

 consistently similar, the most similar being 

 Cinnamomum rossmassleri Heer.^ 



Cinnamomum vera appears to have been 

 common aU along the eastern shore of the 

 embayment during middle and later Wilcox 

 time.

Description. — Leaves small but different in 

 size, oblong-lanceolate in general outline, the 

 apex gradually narrowed and acumkiate and 

 the base cimeate and slightly decurrent. 

 Length ranges from 7 to 10 centimeters. Maxi- 

 mum width, in the middle ])art of the leaf, 

 ranges from L25 to 1.8 centimeters. Margins 

 entire. Texture coriaceous. Petiole very stout,
