Genus PINOSTROBUS, Feistmantel. 

 [Sitzb. k. bohm. Ges. Wiss., 1874, p. 272.] 



Diagnosis. Fossil cones with overlapping scales, having 

 a greater or less degree of likeness to Finns in the narrowest 

 sense, but all clearly of abietinean affinity. 



This generic name was never diagnosed, nor its use com- 

 mented on or explained by Feistmantel, who employed it for 

 two Cretaceous species, Pinostrobus prolonyatus and P. vaU'nhis 

 from Bohemia. It was not adopted by Fritsch & Bayer (1901) 

 in their monograph on the plants of the same deposit, and it 

 does not appear to have been quoted by any other author. 

 It is, however, appropriate for the more or less doubtfully 

 Pinus-like, but certainly abietinean, cones, which occur isolated 

 in the Upper Mesozoic and Tertiary deposits. 



Several writers (e.g., Seward, 1895) use Pinites for such cones, 

 but as Pinites is equally applied to foliage, twigs, cones, and 

 wood, and as it was originally proposed for wood which was not 

 even abietinean, its use is ruled out both by the laws of nomen- 

 clature and the inconvenient vagueness of its application. 



It is well that the names of fossil cones should terminate in 

 -strobus, for then the nature of the specimen is obvious, even 

 in lists where the name only is given. In the present case 

 Pinostrobus is appropriate, as the genus Pinus used at one 

 time to cover the more recently segregated genera Larix, Picca, 

 Abies, etc. 



The following cones are described under this generic name: 



A. Cones closely allied to, if not identical with, the Jiving 



genus Pinus : 



1. Pinostrobus susscxiensis (Mantell), nov. comb. 



B. Cones less clearly allied to any given living genus: 



2. Pinostrobus Benstedi (Mantell), nov. comb. 



3. Pinostrobus oblvngm (L. & H.), nov. comb. 



4. Pinostrobus patens (Carr.), nov. comb. 



5. Pinostrobus cylindroides (Gard.), nov. comb. 



6. Pinostrobus pottoniensh (Gard.), nov. comh. 



7. Pi-nofti'tJivs sp., cf. ? Phtus ff>n</i?*i/iui, Vel.
