FOSSIL PLANTS 157 



This species is represented by several nearly perfect examples as 

 well as by numerous fragments of greater or less size. The largest 

 example (see pi. xxxn) is 15.5 cm. in length and 10 cm. in width. 

 The widest point being in the middle of the blade. The smallest 

 specimen (pi. xxvi, fig. 2) is about 12 cm. in length and 7.5 cm. in 

 width. 



This species is certainly very closely allied to the preceding, and it 

 is possible that only a single species is represented. This appears to 

 differ, however, in being uniformly of much smaller size and in being 

 wedge-shaped at base instead of distinctly heart-shaped. The mar- 

 ginal teeth and the nervation are similar in both, except that midrib and 

 secondaries are relatively lighter in P. alaskana.

Vaccinium alaskanum sp. nov. 

 pi. xxv, fig. i. 



Leaf coriaceous, obovate-oblong, abruptly narrowed at base, obtuse 

 at apex ; margin entire below, finely but obscurely serrate in the upper 

 portion ; midrib strong below, much more slender above ; secondaries 

 thin, about eight pairs, opposite below, alternate in the upper part of 

 the blade, at an acute angle, much curving upward, craspedodrome, 

 each joining the secondary next above ; intermediate secondaries sev- 

 eral ; nervilles numerous, thin, both percurrent and broken, approxi- 

 mately at right angles to the midrib ; finer nervation producing minute 

 areas. 



The single figured example is all that was contained in this collec- 

 tion. It is a small leaf, oblong, slightly obovate, and 4.25 cm. long 

 by 1.5 cm. in width. 



This leaf is apparently not closely allied to any previously described 

 from Alaska. 



Phyllites saundersi sp. nov. 



Pl. XXV, fig. 2 ; Pl. XXXIII, fig. 2. 



The collection contains about a dozen fragments, two of which are 

 here figured. I am uncertain as to the exact nature of these little ob- 

 jects. At first sight certain of the detached specimens have the ap- 

 pearance of being catkins of something like Salix or Populus, but, as
