Morris^ to Jurassic Indian shoots which FeistmanteP afterwards 

 transferred to Palissya: these have recently been included by 

 Halle* in Elatocladus as E. conferta and recorded by him from the 

 rich Antarctic flora of Graham Land. 



In no case have we any definite information with regard to the 

 cones borne by the Cunninghamites type of shoot. Velenovsky* 

 figures some Lower Cretaceous cone-scales from Bohemia, which he 

 refers to Cunninghamia, resembling in shape the scales named by 

 Hollick and Jeffrey Protodammara, but the resemblance may be 

 only superficial. 



The vegetative branches assigned by authors to Cunninghamites 

 have linear-lanceolate leaves usually showing a distinct midrib and 

 often other parallel lines on the lamina which are probably due 

 to hypodermal fibres. The leaves may reach a length of 6 cm. 

 and are 1 — 4 mm. broad; the edge is entire and finely serrate as in 

 Cunninghamia sinensis. A characteristic feature is the occurrence 

 of persistent decurrent leaf-bases on the branches which in some 

 specimens that have lost the free portion of the lamina present a 

 close similarity to Brachyphyllum. Some of the examples of 

 Cunninghamites may well be shoots of a plant allied to Araucaria 

 Bidwillii or A. hrasiliensis. There is no doubt that under Cunning- 

 hamites are included branches of many different Conifers. 



Elatocladus elegans (Corda). 



Originally described by Corda ^ from Lower Cretaceous rocks 

 in Bohemia as Cunninghamia elegans, this species is recorded from 

 many Cretaceous localities; from the Patoot beds in Greenland^, 

 Moravia', Westphalia^, Upper Cretaceous beds in Bulgaria^, the 

 Amboy clays ^"j Cliifwood, Martha's Vineyard i^, Georgia, Carohna^^, 

 and other places in North America^*. The specimen shown in 

 fig. 805 from Moravia shows a midrib in a few leaves, while in the
