A NEW SPECIES OF ARTHROXYLON (CALAMITACEAE) FROM THE PENNSYLVANIAN OF KANSAS

Cridland , Arthur A. (Kansas U., Lawrence.) A new species of Arthroxylon (Calamitaceae) from the Pennsylvanian of Kansas. Amer. Jour. Bot. 46(10): 709–712. Illus. 1959.—Arthroxylon resinaceum sp. nov. is described from 3 specimens found in a coal-ball collected at West Mineral, Kansas. The tracheids have 1 or 2 rows of pits on the radial walls and the pith cells adjacent to the protoxylem canals are filled with brown contents. Fungus spores are present in the tissues of 1 specimen.     

A NEW BOWMANITEAN FRUCTIFICATION FROM THE PENNSYLVANIAN OF KANSAS

Mamay , Sergius H. (U. S. Geological Survey, Washington, D. C.) A new bowmanitean fructification from the Pennsylvania of Kansas. Amer. Jour. Bot. 46(7): 530–536. Illus. 1959.—A new sphenophyllaceous fructification, Bowmanites moorei sp. nov., is described on the basis of coal ball petrifactions from the Fleming coal in southeastern Kansas. One of the simplest species of Bowmanites, B. moorei has only 3 sporophylls in a whorl. Each sporophyll has 3 lobes, the median one fertile, the 2 lateral ones sterile. Each fertile lobe subtends 2 sporangia, resulting in 6 sporangia in a whorl. The sporangia are inverted, being distally attached to separate sporangiophores that arise in pairs, in axillary positions. The sporangial epidermis and epidermis of the lower surfaces of the sporangiophores are characterized by relatively large, thick-walled cells. The spores are small, spherical, and trilete, without distinctive ornamentation of the exine. B. moorei adds to the morphological variation known in Bowmanites, but contributes little toward a phylogenetic interpretation of this morphologically complex genus.     

THREE NEW SPECIES IN THECATILLARIACEAEFROM THE CENTRAL HIGHLANDS OF CENTRAL SCOTLAND

Three species are recognized as additions to the British montane lichen flora:Catillaria gilbertiisp. nov.,Halecania bryophilasp. nov., andH. micaceasp. nov. All three have so far been recorded only from the mica-schist mountains of the Central Highlands of Scotland.     

EARLY ANGIOSPERM REPRODUCTION: CALODA DELEVORYANA GEN. ET SP. NOV., A NEW FRUCTIFICATION FROM THE DAKOTA FORMATION (CENOMANIAN) OF KANSAS

A new angiosperm fructification, Caloda delevoryana, is described from the Cenomanian age Dakota Formation of central Kansas. It consists of a long, narrow, main axis with numerous secondary axes arranged helically around the main axis. These secondary axes are each terminated in a small receptacle bearing numerous conduplicate carpels. No evidence of a perianth or androecium was found. This fructification bears some similarity to a number of different modern orders, such as the Hamamelidales, Alismatales, Najadales, and Piperales, and families, particularly the Platanaceae and the Aponogetonaceae, but cannot definitely be assigned to any modern taxon within the angiosperms. C. delevoryana exhibits several characters traditionally assumed to be primitive in the angiosperms, and several other features of this fossil are proposed as primitive in the evolution of angiosperms. This floral axis, with its compact mass of numerous secondary axes bearing very small fruits and seeds, may be the product of reduction through diminished growth of internodes and carpels, and elaboration through increased repetition of floral modules. This record adds to the rapidly growing body of paleobotanical data on early angiosperm reproductive structures, which should prove important in the assessment of the extent and direction of angiosperm evolution.

POLLEN WALL ULTRASTRUCTURE OF SELECTED DISPERSED MONOSULCATE POLLEN FROM THE CENOMANIAN,DAKOTA FORMATION,OF CENTRAL USA

Seven dispersed monosulcate pollen taxa from the Dakota Formation of Minnesota, Nebraska, and Kansas were examined ultrastructurally. Rugubivesiculites rugosus has gymnosperm affinities based on its anasulcate aperture and the presence and nature of the formation of sacci. Stellatopollis sp. has exine sculpturing restricted to taxa with angiosperm affinities and is monosulcate. The affinities of the other five monosulcate taxa are uncertain and the exines are tectategranular. The sulcus in many of the remaining five taxa are flanked by small flange-like sacci. These five taxa have features found in gymnosperms and also some features of primitive extant angiosperms. The combination of characters of the pollen types presented here does not entirely agree with our current concept of primitive pollen characters as understood from extant ranalean angiosperms.

A NEW SPECIES OF ZOSTEROPHYLLUM FROM THE EARLY DEVONIAN OF NEW BRUNSWICK

A new species of Zosterophyllum, Z. divaricatum Gensel, is described from the late Early Devonian (Emsian) of northern New Brunswick, Canada. It is a Platyzosterophyllum type, consisting of slender sometimes bifurcating axes with laterally borne sporangia oriented to one side of the axis. The species is distinctive in that axes bifurcate within fertile regions and in sporangium shape and attachment. Aspects of the morphology of axis and sporangium cuticle, tracheids, and spores are presented and considered in relation to comparable features in other Zosterophyllum species. Associated vegetative axes exhibiting H- and K-branching patterns and also cuticular features similar to the fertile specimens are described and it is suggested that they may represent parts of the same plant. Zosterophyllum divaricatum is most similar to Z. llanoveranum, Z. fertile, and Z. spectabile, and also resembles Rebuchia ovata to some extent. Z. divaricatum offers considerable information on variation within one species concerning sporangium shape, attachment, and distribution and expands the known diversity of Platyzosterophyllum types.
