208 SPHENOLEriDITJir. 



Cf. Sphenolepidium (Sequoia) subulatum (Heer). 



[PL XVI. Fig. 3.] 



There are a few specimens in the Rufford Collection which 

 differ from the typical S. Sternbergianum (Dunk.), in having more 

 closely arranged, longer and narrower leaves ; they agree very 

 well with Heer's Greenland species Sequoia subulata, 1 and are 

 probably identical with this form, and with the specimens described 

 by Saporta from Portugal as Sequoia subulata var. Lusitanica,? 

 Saporta's variety appears to be hardly justified by the very small 

 differences which he notes between the Portuguese and Arctic 

 forms. There would seem to be no satisfactory evidence to 

 warrant the use of the generic name of Sequoia. 



Ettingshausen's fig. 18, pi. ii. 3 \_Araucarites curvifolius (Dunk.)] 

 bears a strong likeness to the specimen represented in our PI. XVI. 

 Tig. 3 (V. 2140). It is not improbable that some of the specimens 

 figured by Fontaine as Sequoia Reichenbachii, Heer, 4 are identical 

 with the present species. Possibly the following specimens might 

 reasonably be referred to as constituting a variety of Splieno- 

 lepidium Sternbergianum. 



V. 2140. PL XVI. Fig. 3. 



Branches fairly closely set. Leaves narrow, linear and keeled, 

 slightly curved or almost straight. At first sight the branches 

 appear to have a bilateral form as regards the leaf arrangement, 

 but this may be simply due to manner of preservation. Eccles- 

 bourne. Rufford Coll. 



V. 2093. Broken fragments. Leaves fairly distinct. Cf. S. 

 Sternbergianum and Ettingshausen's pi. ii. fig. 18. Ecclesbourne.

 with any certainty to a particular species of the genus.
