280 CORDAITEAE [CH. 



Pelourdea hadroclada (Halle). 



Dr Halle 1 recently published an account of some imperfect 

 leaves and stem-fragments from the Rhaetic of Scania which he 

 named Phyllotenia (?) hadroclada, the generic name provisionally 

 adopted having been proposed by Salfeld 2 for some rather obscure 

 remains from the Corallian of Germany. It appears to have 

 escaped the notice of both authors that Saporta 3 in 1894 had 

 adopted the designation Phyllotenia for some examples of broad 

 parallel-veined leaves from Lower Cretaceous rocks in Portugal 

 very similar to Velenovsky's Krammera mirabilis*. Some other 

 generic name must therefore be used. For the Rhaetic species 

 the name Pelourdea would seem appropriate. The type-specimen 

 consists of an axis 10 12 mm. in diameter with spirally disposed 

 transversely elongated leaf-scars bearing sessile linear leaves 

 similar to Poa-Cordaites ; none of them are complete, the largest 

 is 6cm. long and 5 7mm. broad with 8 12 parallel veins. 

 An examination of the original specimens in the Stockholm 

 Museum satisfied me that Dr Halle is justified in the opinion 

 that they may be fragments of some Cordaitalean plant and that 

 he was well advised to avoid the use of the name Cordaites. 

 Salfeld's species, Phyllotenia longifolia, may be an imperfectly 

 preserved example of Phoenicopsis 5 , but the material is too in- 

 complete to be identified with any degree of confidence. 



Pelourdea Imhofi (Heer). 



The Triassic leaves from Switzerland described by Heer 6 , and 

 more recently by Leuthardt 7 , as Bambusium Imhofi, were referred 

 by Fliche 8 to the genus Cordaites. The lamina is ensiform, 

 25 cm. long with a maximum breadth of 2-4 cm. Leuthardt's 

 photograph of aerial stems and rhizomes of this supposed Mono- 

 cotyledon are far from convincing. 



Pelourdea Jceuperiana (Compter). 



The leaves from the Lower Keuper of Thuringia assigned by 

 Compter 9 to Cordaites without adequate evidence resemble those
