Genus ARAUCAHITES, Presl, 1838. 

 [In Sternberg, Flora Vorwelt, Heft vii, p. 203.] 

 Leaves and cones essentially similar to those of the recent genus 

 Araucaria. With the exception of the following species, the genus 

 has so far been found only in the Mesozoic rocks. 



Araucarites Oldhami, Zeiller. 



1902. Araucarites Oldhami, Zeiller, Pal. Intlica, N.s., vol. ii, p. 36, pi. vii, 

 fig. 6. 



Type. ~No. 7310, Mus. Geol. Surv. India, Calcutta. 



Branches strong, 10-12 ram. broad ; leaves erectly spreading, 

 lanceolate, 35-40 mm. long, 9-12 mm. broad, apex acute, attached 

 by a rhomboidal cushion or pulvinus 5-6 mm. in height; nerves 

 fine, crowded, parallel. 



The specimen, recently described by Zeiller, agrees closely in its 

 characters with certain recent Arauearieae, but in the absence of the 

 fructification it is not safe to refer it to the recent genus. The 

 leaves of this species are probably longer than those of any 

 other known member of the genus. The horizon in the Lower 

 Oondwanas of India from which the specimen was obtained at the 

 Moran River is not certain. 



Not represented in the British Museum collection. 



Genus WALCHIA, Sternberg, 1826. 

 [Flora Vorwelt, Heft iv, p. xxii.] 



Branches regularly pinnate, spreading in one plane, numerous, 

 approximate. Leaves small, falciform, keeled, decurrent at the 

 base, erect or spreading. 



In habit Walchia recalls certain Araucariea?, especially Araucaria 

 excelsa. It is essentially a Paloeozoic genus, appearing first in the 

 Carboniferous and reaching its maximum in the Permian period. 



[Walchia], sp. (from South America). 

 Kurtz * has described a very imperfect fragment, apparently of 

 a Coniferous branch, from Argentina, which he has doubtfully
