TAXINE.E. 



Taxo-torreya. 



According to fclie small branch, described below, of a fossil 

 Taxinca from the strata of Wangapeka, which are ranked 

 among the Chalk formations, we must accept a family genus 

 which unites the characteristics of Ccphalotaxus and Torrcya. 

 The position of the leaves, and the nature of the petiole, are 

 the same as in Cephalotaxus; on the other hand, the nervation 

 is the same as in Torreya. All other characteristics of the 

 formation of the leaf ai'e the same as in both genera.

The small fragment of a branch (fig. 16) is distinguished 

 from the below-described branch of Podocarpnuni by the three 

 nerves which tro/vorse the leaves ; the latter stand closely to- 

 gether, and are arranged in two lines almost opposite each 

 other ; they indicate a strong leathery texture ; they are dis- 

 guished by a short, somew^hat stout stem. All these charac- 

 teristics remind one of Cephalotaxus, especially of C. drupacea, 

 Sieb. et Zucc. (Japan), since this species agrees also with the 

 fossil as regards size and shape of the leaves. In the latter 

 the leaves are 10mm. -15mm. long and 2mm. -3mm. wide, 

 bnt the nervation of the leaves shows the characteristics of 

 Torreya (see the enlargement, fig. 16a). In this genus appears 

 on the underside of the leaves a pronounced and broad mid- 

 nerve, which runs out towards the top, and on each side of it 

 exists a narrower nerve along the leaf, vrhich limits the narrov\' 

 furrow that runs along the mid-nerve. The broad mid-rib, as 

 well as the longitudinal furrows and side-nerves, are distinctly 

 perceptible in the fossil. Of the now living species of Torrcya, 

 T. grandis, Fort., from China, agrees best wdth our fossil as 

 regards size and shape of the leaves.
