and prominent, being raised like threads on the surface of the pinnule. The 

 veinlets are usually simple, but where the pinnules show a tendency to become 

 lobed they are bifid, as seen in the lower lobe of fig. lb. When the pinnules 

 are divided into lobes, the vein in each lobe usually bifurcates, as shown in 

 fig. lc. These lobed pinnules are of somewhat irregular occurrence on the 

 pinnae. At the points marked x and x', where examples of these lobed pinnules 

 occur, that at x is situated on a basal secondary pinna, whereas that at x' is on 

 a secondary pinna, placed well up a primary pinna. On the same primary 

 pinna the majority of the pinnules, even on secondary pinnae borne lower 

 down on the rachis, are only pinnatifid, as seen at z and on the other pinnae 

 of the specimen. 



The main rachis and those of the primary pinnae are very stout, as com- 

 pared with those of the secondary pinnae ; they are feebly striated, and bear 

 slightly elevated points. . 



The only species to which the Camerton plant appears to have any re- 

 semblance are Sphenopteris (Cheilantheites) grypophylla, Goppert,* and Sphen. 

 bidentata, Gutbier.t 



From Sphen. grypophylla, Sphen. Woodivardii is easily distinguished by its 

 lanceolate, upward-directed pinnae, and the pinnatifid pinnules. In Sphen. 

 grypophylla the pinnae are long and linear, and spring from the rachis at almost 

 right angles, and the pinnules are uniformly divided into bifid lobes. In 

 addition, the whole general appearance of the two plants is characteristically 

 distinct. 



The type figure of Sphen. bidentata, Gutbier, is very fragmentary, and, 

 except from the enlarged figure of the pinnule, a comparison of the species 

 with any other is almost impossible. This enlarged pinnule shows a sharply 

 bifid-toothed, spinous-like fern, which, both in the form of the pinnule and its 

 segmentation, is essentially distinct from my plant. 



I have great pleasure in naming this specimen after Dr Henry Woodward, 

 F.R.S., of the British Museum.
