COMPILER'S PREFACE
Volume 42 contains systematic information originally published in
Brenner, 1963, and Khlonova (Chlonova), 1961. Brenner's investigation
constitutes one of the earliest, if not the earliest, major palynological
study of the Lower Cretaceous from the Atlantic Coastal Plain of North
America. His samples included surface and subsurface sediments from
the Patuxent, Arundel, and Patapsco formations (Potomac Group) from
localities in Delaware, Maryland and Virginia. Khlonova's study was
based upon samples from 8 localities in the eastern part of the western
Siberian lowland along the Bax, Cbim, Kemb and Enuceu rivers. These
samples were dated as Late and Latest Cretaceous.
Systematics recorded in this Volume from Brenner, 1963, and
Khlonova, 1961, include 15 new genera, 112 new species, 1 emendation
and 14 new combinations. The emendation and new combinations are
presented as Part I and Part II of the Appendix. New taxa from Brenner
include one genus (Decussosporites) and 65 species, while new taxa from
Khlonova include 14 genera and 47 species. The following names were
proposed by Khlonova for her new genera. Accuratipollis, Circumflexi
pollis, Compactipollis, Deplexipollis, Disyllabipollis, Expressipollis,
Fibulapollis, MUltinodisporites, Occultosporites, Ocellipollis,
Orbiculapollis, Seductisporites, Translucentipollis and Tricerapollis.
Brenner's emendation of Exesipollenites Balme 1957 is reproduced in Part
I of the Appendix, while the 5 and 9 new combinations proposed by
Brenner and Khlonova, respectively are identified along with their
basionyms in Part II of the Appendix.

Brenner's new species were assigned to 40 genera while Khlonova
assigned hers to 28 different genera. About one third of the genera.
to which KhlonoV'a assigned her new or previously described species.
refer to extant plant taxa.
To locate any significant specimen recorded in his 1963 publi
cation. Brenner provided the following method to convert his published
coordinates for use with other mechanical stages. As a base from
which to determine a conversion factor he inscribed an "X" with known
coordinates. on each of three blank slides. which he calls "Key slides".
(In all cases Brenner recorded the horizontal component for any of his
coordinates first.) The difference between the "known" coordinates
on any of his "key slides" and those observed for that "X" position
on the vernier readings of an alternative stage established a conversion
factor between the two stages. Proper "directional" application of the
horizontal and vertical components of this conversion factor to the
published coordinates for any specimen recorded in Brenner. 1963.
will convert his coordinates to vernier readings that will properly
locate that specimen for observation on the alternative stage.
The coordinates of each X is as follows:
Key slide A. coordinates 28.7 x 119.4
Key slide B. coordinates 28.5 x 119.3
Key slide C. coordinates 32.2 x 120.1
Key slides are retained by the author in his personal collection of
type slides.
With regard to Klonova's identification of holotypes repetition
of numerical designations purporting to identify holotypes in Khlonova.
1961. and in the CFSP references. indicate that these designations of
themselves. cannot actually identify an individual specimen. However.
42 :iii
they apparently do identify the slide which carries the type (personal
communications from E. Stanley to H. T. Ames.) In addition to the
numerical designations, Khlonova also provided illustrative
identification of her holotypes, in that figures illustrating the
holotype are so noted in Russian by the word ronoTHn in the accompany
ing captions. CFSP cites these illustrations by plate and figure
as part of its identification of the holotype.
Khlonova's treatment of her proposed new monotypic genera in
1961 would not have provided valid publication of their names when
published, per a strict interpretation of the requirements of Article
PB6 1956 ICBN. This Article reads: "The name of a monotypic genus
of fossil plants published after 1 Jan. 1953, must be accompanied by
a description of the genus indicating its differences from other
genera." Following deletion in 1959 of the Appendix entitled:
"Special provision concerning fossil plants", the essence of Article
PB6 was combined with Article 42 of subsequent Codes until publication
of the 1978 edition of the ICBN. In this edition the special and
restrictive limitation imposed for the names of monotypic genera of
fossil plants was also eliminated. As Khlonova's treatment is now
in compliance with requirements pertaining to the names of monotypic
new genera of both fossil and extant plants, her names must be recog
nized as validly published.
The editors acknowledge, with gratitude, permission from the
authors and publishers to reproduce systematic material from their
publications. We also wish to express our appreciation to G.J.
Brenner and A.F. Khlonova for their aid and helpful suggestions
which contributed to the preparation of Volume 42.
