Gynochthodes cochinchinensis (Rubiaceae), a woody climber, is reported here as a new addition to Indian flora from Similipal Biosphere Reserve, Odisha.  The species resembles its closely allied taxon Gynochthodes umbellata, but can be distinguished from it by a number of distinct morphological characters. A detailed description, notes on habitat, ecology and distribution are provided in this paper with color photographs for easy identification.

The genetic structure of temperate plants was extremely affected by climate changes during the Pleistocene. In East Asia, however, there are a limited number of phylogeography studies of widely distributed species. Actinidia arguta (Sieb. & Zucc.) Planch. ex Miq. (Actinidiaceae), a widely distributed woody climber, was chosen for this study. Twelve haplotypes were obtained using five chloroplast fragments. No haplotypes were shared on two sides of the Qinling–Dabie mountain ranges, indicating a phylogeographic break. The break was further revealed by analysis of molecular variance, spatial analysis of molecular variance, and ecological niche modelling. The most recent common ancestor of all haplotypes showed that global cooling and aridity of the Asian interior at the Pliocene–Pleistocene boundary may triggered this divergence. Two monophyletic lineages (north and south lineage) were revealed by Bayesian phylogeny and the maximum parsimony network. In the north lineage, mismatch analysis indicated an ancient spatial expansion. Distant distribution of closely related haplotypes indicated subsequent allopatric fragmentation. The widespread haplotype H2 implied another significant range expansion. In the south lineage, a considerable rise in sea level of the East China Sea may have triggered population fragmentation. The nested clade analysis also indicated that expansion and allopatric fragmentation were the main processes shaping the haplotype distributions. So, repeated range expansions and fragmentations have shaped the present genetic structure of A. arguta.

This paper presents observations on the population size and conservation status of Derris scandens var. saharanpurensis (Fabaceae), a woody climber endemic to Saharanpur, Uttar Pradesh, India.  The surveys were made in Saharanpur forest division, which forms the type locality of this variety.  On the basis of field observations this taxon is recommended for IUCN criteria of Critically Endangered [CR B1ab(iii,v)+2ab(iii,v)+2c(iv); C2a(i); D].

A new species of Friesodielsia (Annonaceae), Friesodielsia formosa, is described from Borneo. A large woody climber of lowland forests, the species has been collected from Sabah, Sarawak and Kalimantan. A new combination in Friesodielsia is made for Oxymitra grandifolia Merr. which is resurrected from the synonymy of Friesodielsia latifolia (Hook.f. & Thomson) Steenis. The name Oxymitra grandifolia is lectotypified.
