Cookson (1950) erected the fossil pollen genus Banksieaeidites to accommodate palynomorphs with characters resembling those of the extant Proteaceae genus Banksia. One of the most commonly reported species, Banksieaeidites arcuatus Stover & A.D.Partr., is now known to more closely resemble pollen of the Proteaceae subtribe Musgraveinae, than that of subtribe Banksiinae. The late Eocene Mulga Rock deposits in the southern Officer Basin of Western Australia have yielded palynofloras that contain up to 7% of two new species that can confidently be aligned with pollen of modern Banksia. Banksieaeidites davidsonii sp. nov. and B. rugulus sp. nov. are formally described, and pollen from eight extant Banksia are described and compared with the two fossil species. The variation in extant Banksia L.f. pollen morphology, and that between the two Banksia subgenera (B. subgenus Banksia and B. subgenus Spathulatae A.R.Mast & K.R.Thiele) are discussed, and the changes in the morphology of Banksia pollen grains as they mature are reported.

Strobilanthes mullayanagiriensis and S. bislei are plietesial species described for the flora of Western Ghats of India from Karnataka state. Pollen morphology is used as a key character for establishing these two species. Distribution and notes on its allied species are provided along with photographis for facilitating its identification. The former species readily distinguished from its allied species S. consanguinea by coriaceous and scabrous leaves with broadly ovate lamina, crenate margin and cuspidate apex, uninterrupted viscous spikes, longer bract: calyx ratio, much shorter corolla and pollen grains with ribs meet at the poles into two groups and one rib completely encircling the pollen. The latter species definitely distinguished from the allied species by uninterrupted viscous inflorescence with sericeous indumentum, calyx exceeds the bract, anthers are held parallel to the filament and ellipsoid pollen grains with slightly twisted ribs.

A New Species

Epimedium muhuangense (Berberidaceae), a new species from Guizhou, China, is described and illustrated. This species is most closely similar to E. elachyphyllum in having simple leaves, petals shorter than inner sepals, flowers less than 10 mm in diameter and in having the same pollen morphology as well, but differs by having stout, short rhizomes, two opposite, glabrous leaves on flowering stems, and paniculate inflorescences. The chromosomes of E. muhuangense is counted as 2n = 12 and the karyotype is formulated as s 2n = 2x = 6m (2sat) + 6sm. Line illustrations, color photographs, and micrographs of chromosomes and of pollen grains of E. muhuangense are provided.

Abstract Gall midges are reported for the first time in Late Eocene Rovno amber from the Olevsk, Zhitomir Region. This is the second amber locality to yield gall midges in the Zhitomir Region, after Gulyanka. Rovnoholoneurus gen. n. and two new species, Rovnoholoneurus davidi sp. n. and R. miyae sp. n. are described. Bryocrypta laqueata Fedotova, 2005 is transferred to the genus Rovnoholoneurus, and Rovnoholoneurus laqueatus (Fedotova, 2005), comb. n. is established. A key to the species of Rovnoholoneurus is provided.

Two new species, Itaphlebia exquisita sp. nov and Itaphlebia laeta sp. nov., were collected from the Jiulongshan Formation (Middle Jurassic) of Daohugou, Inner Mongolia, China. A key to the species of the genus Itaphlebia is provided and diagnosis of the genus is revised. Itaphlebia exquisita sp. nov differs from other species in having an extra medial vein branch. Itaphlebia laeta sp. nov shows a transitional character to the extant genera by having a simple Sc. These new findings expand the distribution of Itaphlebia from middle-southern Russia to northeastern China.

Banksia microphylla leaf fossils and Banksieaeidites zanthus pollen are newly described from late Eocene lignite of the Zanthus-11 borehole, drilled east of Norseman in Western Australia. The leaf fossils are the first known in Banksia to show extreme narrowness (<1.5 mm wide) combined with the xeromorphic trait of margins rolled onto the lower surface so that the diffusely placed stomata are exposed to the outside environment only via grooves on each side of a thick, abaxial midrib. Both this Banksia leaf type and another with encrypted stomata evolved before the widespread initiation of severe climatic aridity in the late Neogene, likely in regions of edaphic infertility and periodic water stress. New interpretations of leaf morphology and foliar evolutionary pathways in Banksia are proposed. Banksia microphylla probably belongs to subgenus Spathulatae, where it strongly resembles many species in the large, wholly Western Australian clade that includes most species in section Oncostylis, series Abietinae. Banksieaeidites zanthus is morphologically consistent with Banksia pollen, and its extremely small size also suggests placement in Spathulatae. The new fossils and other evidence from Zanthus-11 indicate the local presence of quite open, sclerophyll vegetation with conifers, which was unlikely to have been frequently burnt.
