56 THE FLORA OF THE AMBOY CLAYS. 
with the proper name. To make his identification sure he corresponded 
with Dr. Debey and received from him drawings which distinctly showed 
the twigs to be covered with closely pressed semicircular leaves. These 
convinced Heer of their coniferous character, but Dr. Debey refused to 
accept this conclusion. The numerous specimens figured by Professor 
Heer would seem, however, to leave no doubt upon this subject, and the 
many and beautiful specimens we have obtained from the Amboy Clays, 
some of which are now figured, fully confirm Heer’s views.’ 
No fruit has yet been found with the remains of Moriconia, but this 
want will doubtless be supplied from the New Jersey clays and will per- 
mit its relationship with other conifers to be determined. Judging from 
the foliage alone, Professor Heer is inclined to place Moriconia among the 
Cupressinez and near to Libocedrus. 
When in Aachen in 1888 I had an opportunity of examining some of 
the specimens of Moriconia collected by Dr. Debey, and a few of them 
showed the outlines of the appressed leaves, but most of the specimens 
were very imperfectly preserved, the outlines of the twigs, colored brown, 
being all that remained of the plant. I was anxious to identify this coni- 
fer with that found in the Amboy Clays, for the ample illustration given of 
the species by Heer left no doubt that it is common to the Amboy Clays 
and the Atane group of Greenland, and this was the first of the somewhat 
long list of species common to Aachen, Greenland, and New Jersey which 
enabled me to fix with great certainty the geological horizon of the Amboy 
Clays. 
Locality : South Amboy. 
‘Tt is somewhat remarkable that Professor Heer, after figuring carefully and accurately a number 
of specimens of Moriconia which fully show the peculiar foliage on the plate cited above, should 
have figured on Pl. LIV (op. cit., Vol. VII) a much larger branch of a conifer and called it Moriconia, 
when it is apparent that it is a Brachyphyllum. Instead of being semicircular the leaves are rhom- 
boidal, and it is also probable that the species is the same with Brachyphyllum crassum, p. 51, Pl. 
VII, of this monograph.—A. H.
