62 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
f. 1. 1892; Monog. U. S. Geol. Surv. 50 (Cret. Fl. S. N. Y. 
and N. Eng.) : 46. pl. 3. f. 12. 1906. 
Juniperus macilenta Heer [ ?], Fl. Foss. Arct. 6°: 47. pl. 35. f. 10, 
Iob, 11. 
The single specimen, represented natural size in fig. 5, Pl. 5, is 
the only one thus far brought to light in any of the Kreischerville 
material which could be definitely referred to this species; although 
isolated fragments, apparently belonging to it, are more or less 
abundantly represented in the lignitic debris. These latter, however, 
are difficult to distinguish superficially from other delicate coniferous 
twigs, unless the leaves are all preserved so that the phyllotaxy may 
be made out. Figure 6, Pl. 5, shows a terminal twig, with leaves 
attached, as it appears under an ordinary hand lens. 
If the two species described by Heer are to be regarded as dis- 
tinct, our specimen undoubtedly resembles hypnoides more nearly 
than it does macilenta, although specimens apparently identical with 
ours were described and figured by Newberry from the Cretaceous 
of New Jersey under the latter species.*? 
None of our specimens was found sufficiently well preserved for 
sectioning, so that we are unable to say whether the commonly 
accepted reference of this species to the genus Juniperus may or may 
not be justified. In this connection it is interesting to note that in 
the New Jersey clays the twigs of this tree are closely associated with 
cone scales of Dammara borealis Heer, which are undoubtedly 
closely related to our Protodammara speciosa; in fact, Newberry 
states that they are “sometimes apparently attached to the branch- 
lets,” and that “almost no other plant except this conifer is found 
with the cone scales, and it is difficult to avoid the conclusion that 
they belong together" (1. c., p. 47). This association may possess 
some significance, inasmuch as we have found in similar association, 
in the Androvette pit, the twigs of Juniperus and the cone scales of 
Protodammara, which latter has been determined to be araucarineous 
in its affinities.
