476 PROFESSOR HEEE ON THE FOSSIL FLORA OF NORTH GREENLAND. 
The base of the leaf is rounded, but not emarginate ; the margin is toothed, the teeth 
equal. The secondary nerves spring at acute angles, that nearest the base sends out 
many tertiary nerves, which reach to the teeth, some being forked. The upper secondary 
nerves are undivided ; the nervules in the areas spring at right angles, and are forked or 
undivided. 
XXIII. Araliaceae. 
51. Aralia (SciadojphyllumX) Browniana , Hr., Plates XLII. tigs. 6-8 ; XLIX. 4 e. Foliis 
digitatis X foliolis coriaceis, glaberrimis, oblongo-lanceolatis, basi insequilateris, inte- 
gerrimis ; petiolo longo, tenui. 
Some leaves or leaflets found at Kudliset by Mr. Brown (Plate XLII. figs. 6, 7). Those 
represented in Plate XLII. fig. 8 ; XLIX. 4 e are from Atanekerdluk. Count Saporta 
has figured similar leaflets from St. Zacharie and Armissan as those of an Aralia , and com- 
pared them to those of Sciadophyllum (cf. Ann. des. Sc. Nat. 1863, p. 232, and 1866, 
p. 299). The Greenland leaves support this identification, being leathery (showing 
a pretty thick coal-bark), long petioled, and having unequal bases, indicating the leaflets 
of a compound leaf. 
The fragments figured in Plate XLII. fig. 8 probably formed together a folium digi- 
tatum. They have a long slender petiole (Plate XLII. fig. 6), do not taper into it, and 
have strongly unequal sides. They are oblong, lanceolate, and probably acuminate, 
but there is no av ell-preserved apex. The median nerve is strong, the secondary nerves 
quite obliterated or slightly projecting (see the lower part of the leaf in fig. 8 a), and 
pretty strongly curved. 
In the long petiole it agrees Avith A. Zachariensis , Sap. 1. c. pi. ix. fig. 2 ; but differs 
in not tapering into the petiole, and in its unequal sides. This latter character distin- 
guishes it from A. lanceolata, Sap. from Armissan. The leaf from Udsted in Greenland, 
figured in my FI. Arct. pi. xlix. fig. 6, probably belongs to this species. The secondary 
neiwes are more delicate, and the leaf more leathery, than in Juglans Strozziana. 
52. Hedera M c Clurii, Hr., Plate LII. fig. 8 e. Hr. FI. Arct. p. 119, pi. xvii. figs. 1 a , 
2 o, 3, 4, 5 a. Hab. Atanekerdluk. 
The collection contains several imperfect fragments, shoAving the long slender petiole, 
and the leaf base, Avhich is obtusely rounded. It has five principal nerves, giving off 
secondary nerves on both sides. Plate XLV. fig. 5 b is probably a leaf of the flower- 
ing branch. 
XXIV. Corner. 
53. Cornus hyjperborea, Hr., Plate L. figs. 3, 4. Foliis ellipticis, paucinerviis, nervis 
secundariis sub angulo acuto egredientibus, acrodromis, distantibus. Hab. Atane- 
kerdluk.
