 Porosporites bennholdi (Bode) Zerndt, 



1938, Deuxieme Cong. Stratig. Carbonif., 

 vol. III. p. 1713. Age, Lower Namurian 

 (Flora series). 



Note. — Zerndt credited this specific epithet to 

 Bode, apparently assuming the spores con- 

 specific with those of Porostrobus bennholdi. If 

 Porostrobus can be identified reliably from its 

 isolated spores alone, then evidently Porostrobus 

 is a later homonym of Triletes. Such is hardly 

 the case, however, because the identification of 

 the genus Porostrobus and the species bennholdi 

 within it depend on other features in addition 

 to the spores. Some day we possibly may know 

 actually how diagnostic isolated spores of 

 Porostrobus may be, but at present such speci- 

 mens certainly must be recorded separately 

 under a different genus (as Zerndt has done). 

 Consequently, also, these forms must be identi- 

 fied with reference to different nomenclatural 

 types. The specimen illustrated by Zerndt's 

 photograph 4, plate 2, and which evidently 

 served as the basis for his text figure 3 (p. 6), 

 is regarded as the holotype of the species which 

 is here credited to Zerndt. 



On the other hand, no question arises as to 

 the spores Wicher (1934b) described in some 

 detail that were isolated from undisputed speci- 

 mens of Porostrobus. There was no occasion 

 for him to assign them a new generic name 

 (Poro(strobo)sporites) since the only possible 

 designation for the specimens is "spores of 

 Porostrobus bennholdi." Zerndt, in using the 

 name "Porosporites" in 1938, is presumably 

 following Wicher. Wherever evidence of addi- 

 tional cone characters warrants it, such a deter- 

 mination is more significant and essentially 

 useful than identification with a less closely 

 defined group such as Triletes. Mistakes of this 

 kind are less likely to occur if nomenclatural 

 types are regarded seriously.

 comb. nov. 



Sporites bipilosus Wicher, 1934, Inst. 

 Palaobot. Arb., vol. 4, no. 4, p. 180, pi. 

 8, figs. 13, 14. 



Sectio, Lagenicula. Age, Lower West- 

 phalian C. 

 Note. — This species is apparently closely re- 

 lated to Triletes robertianus and T. latihirsutus.

 figs. 1-2. Age, Dinantian, Namurian 

 Westphalian A, B. 

 Note. — Closely related to Triletes circumtex- 

 tus, T. saturnoides and T. superbus.

 antian (Raczna series). Lower Namurian

 Note. — Evidently by mistake an illustration 

 of Triletes horridus accompanied Nowak and 

 Zerndt's original description. The species was 

 validated by photographs published a year later.
