64 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN 
The probable botanical relationship of the genus has never been 
satisfactorily determined, although the question has been discussed 
by nearly every author who has had occasion to study it. Heer says 
in his “ Jura-Flora ” (1. c., p. 65), “ Die auf Taf. V. und Taf. ГІ. 
с Pflanzen ШЕ einen so eigenthümlichen Pflanzentypus 
dar, das es schwer hält, für denselben die richtige systematische Stel- 
Dues auszumitteln” ; ànd he further remarks that the first impression 
is that the remains are bundles of pine needles, but that the forking 
of some of the leaves show that they cannot belong to this genus. 
Their resemblance to certain pteridophyta, especially to the genus 
Isoëtes, is then discussed, but is regarded as untenable, and the con- 
clusion is finally reached that they probably belong in the Gingkoales. 
This conclusion seems to have been quite generally accepted by paleo- 
botanists and the genus is now commonly regarded as closely related 
to Trichopitys, Jeanpaulia (Baiera), Gingkophyllum, etc. 
It is unfortunate that in none of our specimens is the basal part 
preserved. It is probable, however, that fig. 1 represents an upper 
and fig. 2 a lower portion. Figure 3 represents an enlarged frag- 
ment of one of the forking branches as it appears under a hand lens. 
In no instance have we been able to definitely identify any of the 
lignitic remains with the species under discussion, but it is possible 
that certain leafless twigs, showing well preserved internal structure, 
representing the genus .1raucariopitys (see р. 54 of this Memoir), 
may belong to it, and if such should be the case, it would be another 
example of a conifer of araucarineous affinities from the Kreischer- 
ville deposits, in this instance simulating the Gingkoales in external 
appearance.

Figure 15, Pl. 9, depicts a small coniferous twig, X 10, rep- 
resented by a single specimen, which, however, sufficiently illustrates 
the external appearance of the species. It is strongly suggestive of 
certain twigs which have been described by Heer under the genus 
Brachyphyllum 5° from the Jurassic and Cretaceous of Portugal
