DESCRIPTION OF srECIES— MYKICACEJE. 133 



myrica Bolnndcri, Lesqz. 



Plate XVU, Fig. 17. 



Jlex undulata, Lesqx., Annual Report, 1873, p. 410. 



Leaf oblanceolate, obtusely pointed, dentate at the top ; secondary veins camptodrome. 



A single leaf, about six cenlimeters long, one and a half centimeters 

 broad toward the point, coriaceous, obtuse, and obtusely pointed at the top, 

 which is marked by a few teeth on each side, entire downward, and gradually 

 decreasing to a broad, wingedC!) petiole (broken); middle nerve narrow; sec- 

 ondary nerves at irregular distance and on an acute angle of divergence, thin, 

 camptodrome; areolation obsolete. 



Though this leaf recalls by its form and texture species of Ilex of the 

 present time, some of its characters, the enlarged base of the leaf the narrow 

 middle nerve, the disposition of the secondary veins, seem to refer it more 

 probably to this genus. 



Habitat. — Locality unknown. Check-number H 1295, sent with spe- 

 cimens from Castello's Ranch, Colorado, and apparently from the same place 



(Dr. F. V. Hayden). 



Myrica Liiidwif^iii Scbp. 



Plate LXV, Fig. 9. 



Myrica Ludwigii, Schp., Pal. V<5g^t., ii, p. 545. 



Myrka longifoUa, Ludw., Palasont., viii, p. 94, pi. xxviii, figs. 8, 9; xxix, figs. 1, 3, 5, 6, 7; xxx, figs. 1, 

 19; Ix, fig. 15.— Lesqx., Annual Report, 1874, p. 311. 



Leaves of middle size, subcoriaceous, linear-lanceolate, gradually tapering into a long entire 

 acumen, distantly deeply dentate in the middle ; midrib thick; secondary veins subopposite, open, par- 

 allel, curved in passing to the borders, camptodrome. 



This leaf, of which we have only the uppor part, a little more than one- 

 half, seems evidently referable to the European species described from a large 

 number of specimens; the form of the leaf, with its long acuminate entire 

 point, corresponds to that of Ludwig {loc. cit., pi. xxviii, fig. 8); the midrib is 

 somewhat broader in the American specimen, and the secondary veins at a 

 slightly more acute angle of divergence; but these characters are reproduced 

 in the leaves figured by the German author, the broad midrib in fig. 1 of pi. 

 xxix, and the more oblique secondary veins in pi. xxx, fig. 1. As far as it is 

 seen upon our fragment, whose areolation is obsolete, the details of nervation 

 have the same characters, the secondary veins curving along the borders, 

 and the teeth being entered only by veinlets outside of the primary areas. 

 As remarked by Schimper, this species goes to the same group as Myrica 

 acuminata, etc., its nearest relation among the living species being M. cerifera,
