DESCRIPTION OF SPECIES. 101 
base, but branching above and forming an intricate network along the 
margins, which are finely and uniformly crenate-dentate. 
In his Kreideflora von Niederschoena (pp. 257, 260, Pl. ILL, figs. 1, 3, 
9, and 11) Ettingshausen describes some lanceolate leaves with serrated 
borders, which he calls respectively Dryandroides Zenkeri and Celastrophyllum 
lanceolatum; and Velenovsky, in Die Flora der Béhmischen Kreideforma- 
tion (Part II, p. 13 [88], Pl III, figs. 1-9), describes a series of similar 
leaves, all of which he regards as of the same species, and calls them 
Myrica Zenkeri. So also he claims Celastrophyllum ensifolium Lesq. (Cret. 
Fl, pp. 108, 109, Pl. XXI) and Heer’s Proteoides ilicoides (Kreideflora 
von Quedlinburg, p. 13, Pl. II, figs. 7, 8) as only forms of Myrica Zenkeri. 
Doubtless the leaves which we now figure and name Celastrophyllum angus- 
tifolium would be thought by him also to belong to the same species; but 
there is one distinguishing mark which separates them, and that is that all 
of our leaves are beautifully crenate, while those described by Ettings- 
hausen and Velenovsky are dentate, and so I am led to believe that, 
though perhaps generically identical—but rather as Celastrophyllum than 
Myrica—specifically our leaves are distinct. The relationship of these 
leaves to the still more common ones by which they are accompanied, 
C. grandifolium, is intimate and interesting. There can hardly be a doubt 
that they are members of the same genus, and that genus, it seems to me, is 
Celastrephyllum.

CELASTROPHYLLUM NEWBERRYANUM Hollick n. sp." 
Pl. XLIX, figs. 1-27. 
Leaves small, 2.5°™ to 6™ long by 1™ to 2.5™ wide, generally ovate, 
often obovate, in outline, somewhat narrowed and wedge-shaped at the 
base; margins usually set with sharp, appressed, spiny denticles, but 
sometimes entire; summit generally acute, sometimes apiculate, but not 
infrequently evenly rounded; nervation distinct, camptodrome, and very 
closely resembling that of Celastrus scandens L. 
'The original manuscript name by Dr. Newberry is C. denticulatum n. sp., but this name was pre- 
viously used by Professor Fontaine in his Potomac or Younger Mesozoic Flora, p. 306 (1889). This 
specific name is therefore preoccupied, and in its place I have associated Dr. Newberry’s name with 
the species.—A. H.
