 straight. A single stout lateral primary di- 

 verges from the midrib at an acute angle at its 

 extreme base on either side and terminates at 

 the tip of the lateral lobe. Tlie secondaries 

 are thin, numerous, jiscending, and campto- 

 drome, tho basal lateral secondaries being 

 especially long and ascending, tlie others Ix^ing 

 subparallol. Tertiaries mostly i^ercurrent, 

 open. 



This species, which shows considerable re- 

 semblance to some of the Upper Cretaceous 

 forms that have been referred to the genus 

 Sassafras, was described from material col- 

 lected in the Dakota sandstone of Ellsworth 

 County, Kans. Small loaves are abundant in 

 the characteristic concretionary s|)ecimens, 

 which I believe represent the true Dakota 

 sandstone rather than older beds in tliat area. 

 The species is not abundant in tho Woodbine 

 sand, but there are several specimens in the 

 relatively small collections from that foiina- 

 tion, to which and the Dakota this form ap|)ears 

 to be confined.

Leaves of relatively small size, lanceolate, 

 falcate. Length about .") to cciitimelors; 

 maximum width, about halfway bclwiMMi the 

 apex and the base, if anything slightly nearer 

 the base, about 1.7 centimeters; from this 

 point the blade luirrows to the lanceolate ba.se 

 and gradually tapers to the extended acuminate 

 tip. petiole not |)reserved. Midrib nnich 



curved, thin ilistad. Secondaries three or four 

 pail's; tho lower suprabasilar and subopposite 

 pair should possibly be termed lateral |)rinuiries, 

 as Les(|uereux called tlieiii. Those lower 

 secondaries are thin and l)raiich from tho mid- 

 rib at angles of 1.")° or less, sweeping upward in 

 a long curve, at length cainptodroino. Upper 

 secondaries somewhat irregularly s|)aced, cainp- 

 todroino. Tertiaries very fine and more or loss 

 obsolete. Texture coriaceous but not thick. 

 This attractive species is easily distinguished 

 from other lauracoous forms, particularly from 

 species of Cinnamomum, with which Lesque- 

 reux originally compared it, by its slight in- 

 (■(luilaterality and marked falcate form, as well 

 as by the lack of deliniteness in the triple 

 venation, tiie supral)asilar position of the so- 

 called primaries, and tlie character of the 

 tertiary venation. It was described originally 

 from material found in the Dakota sandstone 

 near l)<"lp]ios, Kans., and subso(piently was 

 discovered by me in the Msigoth}- formation of 

 Xew Jersey. Some of the specimens from the 

 lower part of tho Tuscaloosa formation of Ala- 

 bama, though the material is not extensive, are 

 comi)leto and are entirely characteristic, as is 

 the single specimen discovered at Arthurs 

 Bluff, Tex. It may readily be distinguished 

 from Malapni una fiorrellen.si9 Berry ,-''^ of the 

 Upper Cretaceous IJlack Creek, Eutaw, and 

 Ripley formations, by its suprabasilar primaries 

 and cuneate base.
