392 GEOLOGICAL SURVEY OF THE TEREITORIES. 



star-like uj)oii a slightly inflated short pedicel ; the seeds are obovate, 

 apparently surrounded by a perigynium like seeds of Carex, or, rather 

 similar by form and position to those published by Heer, Fl. Tert. 

 Helv. III., p. 171, PL cxlvii., Fig. 28, as Laharpia umhellata. The buds 

 along the stems are sessile and may represent unopened receptacles.. 

 The relation of these remains is as yet unknown. The stems, distantly 

 articulate, bearing sometimes one large branch-scar, with smaller scar& 

 in rows, might be comparable to Fhragmites. But they are entirely 

 smooth, not striate in the length, and moreover differ by the mode of 

 branching, and by the form of the scars. The relation to Sparganium 

 seems at first admittable on account of the small sessile groups of 

 flowers, or of fructification; but this analogy, too, is rendered doubtful 

 by the mode of branching and the articulations of the stems. 



POPULUS ATTENUATA, Al. Br. 



A small leaf, with strongly creuate borders. The leaf is still smaller 

 than the one in Fl. Tert. Helv., PI. Ivii., Fig. 8, and could be referred to 

 a variety of Fopuhis onutaMlis, repando crenata, but for the deeply 

 crenate border and the thinner substance of the leaf. 



PopULUS LEUCOPHYLLA, Uug., in Kept. 187l', p. 296. 



A small leaf, with the borders less deeply undulate-lobed than in the 

 form represented from European, and especially from Alaska specimens. 

 They are merely deej^ly undulate. The nervation is distinctly that of 

 the species. 



Myrica ToRREYi, sp. nov. 



Leaves membranaceous, narrowly lanceolate, tapering to a long, linear, 

 narrow point, gradually narrowed to a short, broad petiole, distantly 

 toothed, penninerve. 



The medial nerve is broad, secondary veins numerous, variable in 

 distance, emerging on a broad angle of divergence, 60°, ascending to ^ 

 marginal vein which follows the borders, separated by intermediate 

 veinlets, anastomosing with them in broad, irregular meshes. The 

 leaves vary from 1^ cent, to 3 cent, wide, the largest is 16 cent, long 

 from the base of the petiole, which is 2 cent. ; most of the leaves are of 

 the larger size; the borders are distantly but distinctly obtusely 

 toothed, as in Myrica (Banksia) longifoUa, Ett., to which this species is 

 closely related. It is, however, by its nervation, a true Lomatia, and by 

 this character is referable to Lomatia horealis, Heer, Fl. Bait., p. 79, PI. 

 xxiv., Figs. 9 to 13, differing essentially from it as from Myrica longifoUa, 

 by the large size of the leaves, &c. The positive relation of these leaves 

 to the genus Lomatia seems, however, controverted by the presence of 

 small oval seeds, apparently seeds of Myrica, on the same shale as^ 

 the leaves. These nutlets are S mill, long and nearly as wide, obtuse 

 on one end, slightly pointed at the other, convex and narrowly obscurely 

 striate, resembling the fruits of Myrica acuminata, Ung., as published in 

 Heer's Arct. Fl., p. 102, PI. iv., Figs. 15 and 16. One of my specimens 

 has even a fragment 0f a small catkin, like that represented in Fig. 15a. 

 It is therefore advisable to consider this fine species as belonging ta 

 Myrica.
