Leptophytum, based on its generitype, L. laeve, was shown to be a distinct genus more closely related to Clathromorphum than to Phymatolithon, and Variation in rbcL and psbA sequences suggested that multiple species may be passing under each currently recognized species of Clathromaorphum and Neopolyporolithon.
A molecular phylogeny and classification of Leptochloa (Poaceae: Chloridoideae: Chlorideae) sensu lato and related genera.
The molecular results support the dissolution of Leptochloa s.l. is polyphyletic and strong support was found for five lineages.

The phylograms suggest that Muhlenbergia originated in North America because the sister (Sohnsia filifolia and Scleropogoninae) is composed of predominantly North American species.
Sporolithon tenue sp. nov. (Sporolithales, Corallinophycidae, Rhodophyta): A new rhodolith‐forming species from the tropical southwestern Atlantic
A new species conforming to the generic description of Sporolithon was found forming small rhodoliths at 18–75 m depth on the eastern coast of Brazil and molecular phylogenetic analyses of psbA sequence alignments show that the new species is phylogenetically distinct within the genus Sporolithicon.
Generic Relationships and Classification of Tribe Paullinieae (Sapindaceae) with a New Concept of Supertribe Paulliniodae
Sapindaceae tribe Paullinieae is newly recognized and morphologically characterized by zygomorphic flowers, thyrses with lateral cincinni, corollas of 4 petals, and alternate leaves with a well-developed distal leaflet.
Sporolithon yoneshigueae sp. nov. (Sporolithales, Corallinophycidae, Rhodophyta), a new rhodolith-forming coralline alga from the southwest Atlantic
The aim of this study was to describe the new rhodolith-forming coralline alga species, Sporolithon yoneshigueae sp. nov., based on both morpho-anatomical and molecular data. Specimens were collected…
Chloroplast phylogenomics of the New World grape species (Vitis, Vitaceae)
Vitis L. (the grape genus) is the economically most important fruit crop, as the source of grapes and wine. Phylogenetic relationships within the genus have been highly controversial. Herein, we…
Evaluating the diversity of pteridophyte embryology in the light of recent phylogenetic analyses leads to new inferences on character evolution
This is the first review of the developmental morphology of pteridophyte embryos since molecular phylogenies revolutionized concepts of tracheophyte evolution and may provide clues totracheophytes evolution and novel developmental mechanisms.
Embryology of Ceratopteris richardii (Pteridaceae, tribe Ceratopterideae), with emphasis on placental development
This comprehensive study of early embryology in Ceratopteris richardii combines light microscopy with the first ultrastructural evaluation of any pteridophyte embryo, providing an anatomical framework for future comparative developmental genetic studies of embryogenesis in free-sporing plants.
