74 PHOBNICOPSIS [ciT- 



in the lamina and a faintly marked interstitial 'vein/ probably 

 the impression of a stereome strand, between each pair of veins. 

 In one specimen Heer found 21 leaves in a single cluster but 

 usually the number on a single dwarf-shoot is smaller. It was 

 the superficial resemblance of a cluster of these leaves (fig. 663) 

 to the leaf of some Palms that suggested the name Phoenicopsis. 

 The leaves described by Heer as P. latior^ are not distinguished 

 from P. speciosa by any very definite character. Examples of 

 detached leaves from Lower Jurassic rocks in Bornholm described 

 by Moller^ as cf. Phoenicopsis latior may equally well be referred 

 to Podozamites. 



Phoenicopsis angustifolia Heer. 



The leaves are 4 mm. broad or less and have 6 — 8 veins without 

 interstitial veins^. This species is recorded from Eussia*, Siberia, 

 China, and the Arctic regions, and leaves of similar type are 

 represented by Phoenicopsis media Krasser^, which is probably 

 merely a form of P. angustifolia^; P. taschkessiensis Krass. from 

 China ; also Chinese specimens first described by Potonie' without 

 a specific name and afterwards named by Krasser^ P. Potoniei. 



The species Phoenicopsis Gunni from Scottish Kimeridge beds 

 is a similar type with leaves 3 — 4 mm. broad and 12 cm. long with 

 eight veins and indications of interstitial ' veins.' 



? Phoenicopsis elongatus (Morris). 



Morris^ founded this species on a linear leaf, now in the British 

 Museum, from the Jerusalem Basin (Triassic), Tasmania, which he 

 referred to Zeugophyllites, a genus founded by Brongniart on a 

 specimen from the Lower Gondwana rocks of India but never 

 figured. To the same species McCoy^" referred some broader 

 leaves from Permo-Carboniferous strata in New South Wales : 

 these were shown by Etheridge^i and Arber^^ to be distinct from 

 Morris's type and the latter author identified them with Noeg-
