Genus TAXITES, Brongniart. 



[Prodrome, p. 108, 1828.] 



In speaking of this generic name Brongniart points out its 

 artificial character, and calls attention to the fact that several 

 other recent Conifers agree very closely with the Yew in the 

 form of the vegetative shoots.' In the absence of any evidence 

 .as to the character of the flowers, we may conveniently retain 

 Brongniart' s genus for the fragments described by Leckenby from 

 the Inferior Oolite of East Yorkshire.

Type-specimen. The specimen figured by Leckenby is in the 

 Woodwardian Museum, Cambridge (No. 286). The vegetative 

 .-shoots resemble those of Taxus haocata, Sequoia sempervirens, and 

 other recent species ; they consist of a slender axis beariug narrow 

 linear leaves, traversed by a single median vein. The leaves are 

 spirally disposed and more or less closely set. Plowers unknown. 



The fragment to which Phillips gave the name Taxites laxus 

 is in all probability specifically identical with Cycadites zamioides, 

 Leek. The spiral disposition of the leaves, as well as the small 



' Brongniart (28-), p. 75.
