“…Sueria laxinervis also has vascular bundles arranged in the inverted-omega shape, providing another line of evidence that the genus Sueria belongs in Cycadales. This arrangement is markedly different from that in the midrib of the bennettitalean species Nilssoniopteris oishii Yamada et al (2009: 411), which has a taeniopterid-type leaf and vascular bundles arranged in a circle (Yamada et al 2009), as in the other bennettitalean species (Dower et al 2004, Yamada 2009.…”

A new fossil cycad species, Sueria laxinervis, is described from the Upper Cretaceous (Maastrichtian) Quiriquina Formation in Cocholgüe, Bíobío Region, Chile. The generic assignment is supported by the taeniopterid-type leaf with haplocheilic stomata and sinuate anticlinal walls of leaf epidermal cells, while S. laxinervis clearly differs from the other two described Sueria species in its sparse veins and large epidermal cells. The vascular bundles of the midrib are arranged in an inverted-omega shape, supporting the placement of Sueria in Cycadales.

“…However, Nilssoniopteris amurensis is very distinct in its amphistomatic leaves which lack abaxial trichomes. The two anatomically preserved Early Cretaceous Nilssoniopteris leaves are difficult to compare with the two new Mongolian taxa (Yamada et al 2009, Ray et al 2014. However, N. oishii from the Barremian Arida Formation of Japan can be distinguished from N. tomentosa and N. shiveeovoensis on the basis of its segmented lamina and predominantly unbranched lateral veins (Yamada et al 2009).…”

Two new Early Cretaceous (Aptian-Albian) species of fossil bennettitalean leaves are described from central Mongolia and assigned to the genus Nilssoniopteris. Nilssoniopteris tomentosa F.Herrera, G.Shi, Tsolmon, Ichinnorov, Takahashi, P.R.Crane, et Herend. sp. nov., isolated from bulk sediment samples collected for mesofossils in the Tevshiingovi Formation at the Tevshiin Govi opencast coal mine, is distinctive in having a dense, well-developed indumentum composed of branched, flattened multicellular trichomes on the abaxial leaf surface. This species provides the first direct evidence of complex multicellular trichomes in Bennettitales and adds to the evidence of leaf anatomical features in the group that were probably advantageous in increasing water use efficiency and/or perhaps had other functions such as deterring insect herbivory. Comparison with other well-preserved leaves of Bennettitales, including Nilssoniopteris shiveeovoensis F.Herrera, G.Shi, Tsolmon, Ichinnorov, Takahashi, P.R.Crane, et Herend. sp. nov., collected as hand specimens from the Khukhteeg Formation at the Shivee Ovoo locality, suggests that the trichome bases seen commonly on the abaxial cuticle of bennettitalean leaves bore trichomes with very low fossilization potential. In some cases these trichomes may have been shed as the leaves matured, but in other cases they probably decayed during diagenesis or were destroyed during the standard processes by which fossil leaf cuticles are prepared.

The University of Chicago Press is collaborating with JSTOR to digitize, preserve and extend access to International Journal of Plant Sciences. Premise of research. A new species, Nilssoniopteris binggouensis (Bennettitales), is recognized from the Lower Cretaceous Binggou Formation from western Liaoning Province, northeast China. This is the first time that fossil plants are reported from the Early Cretaceous Binggou Formation from Liaoning Province. The new species is one of the youngest-known Bennettitales from China.Methodology. Fossil specimens were examined using SEM and LM and were compared with other published taxa.Pivotal results. Based on leaf morphology and epidermal characters, we describe a new species, N. binggouensis. The leaf is petiolate with entire margin and fine, parallel lateral veins. The leaf lamina is hypostomatic. The anticlinal walls of epidermal cells are strongly and tightly folded. The stomatal apparatus is brachyparacytic (psyndetocheilic).Conclusions. The occurrence of the new species in the late Early Cretaceous of western Liaoning Province significantly extends the stratigraphic and geographic distribution of the genus Nilssoniopteris in the Northern Hemisphere. It represents one of the easternmost occurrences of this predominantly Eurasian genus. This report increases our knowledge of this Early Cretaceous fossil site and improves our understanding of the diversity of the Bennettitales.
