XLVIl] GEINITZIA 357 



S. Whymperi. This more robust form occurs also in Spitzbergen, 

 on the Mackenzie River, and elsewhere. Knowlton 1 records 

 S. Couttsiae along with other species from beds probably of Miocene 

 age in the Yellowstone Park: he assigns to this type specimens 

 described by Lesquereux from Colorado as Glyptostrobus Ungeri 

 and others from the Fort Union Group referred by Newberry to 

 Glyptostrobus europaeus. The cone-bearing branches figured by 

 Lesquereux 2 from the Western Territories as Sequoia affinis bear 

 a close resemblance to S. Couttsiae. The latter species is recorded 

 by Penhallow 3 from the Eocene beds on the Deer River in Canada 

 (lat. 51 and 54 N.). The same or a closely allied type is recorded 

 from Miocene beds in Alsace 4 , and Saporta 5 describes very good 

 examples of S. Couttsiae from the Eocene beds at Armissan in 

 Provence. According to Gardner the material referred by Saporta 

 to Heer's species includes at least two other species. Specimens 

 described by Schmalhausen 6 from Eocene beds in South- West 

 Russia as S. Couttsiae, though possibly correctly named, are not 

 convincing. Palibin 7 records this species from Oligocene beds at 

 Molotytchi in the Fatej district, Russia, and discusses the geological 

 age of the strata from which Schmalhausen 's plants were obtained. 

 Ettingshausen's specimens from Bilin in Bohemia assigned by 

 him to T-axodium dubium may, as Gardner says 8 , be examples of 

 S. Couttsiae. 



GEINITZIA. Endlicher. 



The name Geinitzia was given by Endlicher 9 to a piece of sterile 

 shoot from Lower Cretaceous strata in Saxony previously figured 

 by Geinitz 10 as Araucarites Reichenbachii (fig. 769), and in the new 

 genus was also included Cryptomeria primaeva Corda 11 . Both these 

 species were referred by Endlicher to Geinitzia cretacea. Corda's 

 species was founded on several foliage-shoots from Lower Cre- 

 taceous rocks in Bohemia with the habit of Araucaria excelsa and 

 in one or two instances bearing what appear to be terminal buds 

 described by Corda as small cones. In the first instance Geinitzia
