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. proposed by Khlonova for her new genera.

The following names were

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.

42:ii

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 publication. 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.) numerical designations, Khlonova

In addition to the

also provided illustrative

identification of her holotypes, in that figures illustrating the holotype are so noted in Russian by the word ronoTHn in the accompanying 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 recognized 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.

Description;

TrilL'\e spore; laesurae Nセ@ to full radius, ャBoョゥウ|Gセ@ honlered by a narrow lip ca. til wide; outline in polar view triangular with convex sides and acute to fairly rounded corners. Exine two-layered, ca. 2 Il thick; endexine and ektexine approximately of equal thickness. The endexine is smooth and rigid; the ektexine characteristically separates from the endexine and develops radial folds on bOlh surfaces; the folds make the margin of the spore appear undulate. DimCltsiolls: Maxilllulll diameter 2g(3-l)-ltll (13 specimens).

l[Deplexipollis is identified as a synonym of Wodehouseia Stanley 1961 in Potonie, 1966, pp. 190-191 on the grounds that the type species of the two genera are conspecific and that Wodehouseia was validly published prior to Deplexipollis.
