Remarks. The specimen I identify as Rhabdocarpus multistriatus is about 

 I inch long and f iuch broad at its widest part, which is about one-third of au 

 inch above its base. On the exposed surface of the fruit there appear to 

 be nine or ten longitudinal ribs, which are alternately strong and weak. The 

 specimen is intermediate in size between Rhabdocarpus multistriatus and 

 Rhabdocarpus lineatus, Goppert and Berger (De Fruct. et Seminibus, pi. i. 

 fig. 18). It agrees well with the figures of Rhabdocarpus multistriatus given 

 by Lesquereux (Coal Flora of Pennsyl. pi. Ixxxv. figs. 22, 23), but is slightly 

 less. This difference in size is not apparently specific. 



Some of the figures of Trigonocarpum Schulzianum given by Fiedler 

 (Foss. Friichte d. Steink. Form.), especially his figures on pi. xxvi., approach 

 very closely to Rhabdocarpus multistriatus, if they are really distinct from it. 

 In any case it is difficult to understand how this fruit should be retained (as 

 figured by Fiedler) in the genus Trigonocarpus. The greater prominence of 

 three of the angles, as mentioned by him in his description, can scarcely be 

 said to agree with his figures. 



Rhabdocarpus carinatus and Rhabdocarpus apiculatus, Newberry, do not 

 seem to differ from Rhabdocarpus multistriatus, and with this last-mentioned 

 species, perhaps Rhabdocarpus insignis, Dawson, and Rhabdocarpus oblongatus, 

 Fontaiue and White, should also be united.
