narrower in proportion to their length and longer than those of C. 7nag- 

 nifolia, and the nerve is decidedly more slender. The most perfect 

 specimen shows a length of the part above the base to the termination 

 of the leaflet that equals 21 mm. The base is not shown, but the leaflet 

 was evidently considerably longer than the portion shown. The width 

 is greatest at the lower end of the leaflets, where they equal li mm. It 

 tapers very gradually to the end, near which it is less than 1 mm. in 

 width, and it ends in an acute tip. It is then certainly not Abietites. 

 The tapering shows that it is not Pinus and not Leptostrobus. It is 

 most probably a new species of Cephalotaxopsis."

The presence of Nageiopsis longifolia Font, in the flora of the Shasta 

 formation can not be positively determined from the specimens found. 



« The above is P.rofessor Fontaine's original description given in his first report, dated February 23, 1894, 

 which was sent to Mr. Diller and Dr. Stanton at that time. The species was named Cephalotaxopsis spJ and 

 only this name was published in their paper. In his final report on the combined collections this specimen was 

 returned among those referred to Cephalotaxopsis ramosa Font.? and was drawn as such, but the drawino- 

 brought out the fact, which seems to have been overlooked, that, unlike the other specimens, fine transverse 

 wrinkles or strise pass from the midrib to the margin the whole length of the leaf. I therefore hesitated to 

 include it among the figures of C. ramosa ?, and took the pains to return the specimen, accompanied by the draw- 

 ing, to Professor Fontaine and ask him how he would interpret this feature. In his reply dated July .31, 1902 

 he says: 



'■ I have examined the specimen carefully with a lens. The transverse lines are distinct under the lens, but 

 are of unequal strength and have no definite plan. I think they are shrinkage wrinkles formed on a thick leaf, 

 and that the plant is most probably a Cephalotaxopsis, possibly a new species." 



It seems best to regard it as a new species and consider the generic attribution doubtfu .. The specific name 

 chosen is intended to refer to the wrinkled appearance, while not positively implying that the appearance is due 

 to wrinkling. The specimen was collected at locality No. 9. — L. F. W.
