A new genus, Androcalva C.F.Wilkins & Whitlock, is here described and includes 22 species previously described as Commersonia, four species formerly described as Rulingia and seven new species, including A. aphrix C.F.Wilkins, A. perlaria C.F.Wilkins, A. bivillosa C.F.Wilkins, A. adenothalia C.F.Wilkins, A. fragifolia C.F.Wilkins, A. incilis C.F.Wilkins and A. lachna C.F.Wilkins. Rulingia pauciflora Turcz. is here placed in synonymy with C. gaudichaudii J.Gay as A. gaudichaudii. Recognition of Androcalva is supported by the results of a previous molecular phylogenetic analysis demonstrating that neither Rulingia nor Commersonia as previously circumscribed is monophyletic. Species of Androcalva share characters of extrorse anther dehiscence and glabrous central staminodes. In contrast, species in the redefined Commersonia have anthers with sublatrorse dehiscence and hairy central staminodes. Taxonomic descriptions, a key, distribution maps, conservation status and illustrations are presented.

Neochloroglyphica gen. nov. and its type species N. perbella sp. nov. are described from Yunnan, China. Morphological characters and molecular phylogenetic analysis, based on one mitochondrial and three nuclear genes, support the hypothesis that Neochloroglyphica is a member of the tribe Neohipparchini, and that it is a sister genus to Chloroglyphica. Morphological characters, including those of the genitalia, are figured and compared with related genera, especially Chloroglyphica, Neohipparchus and Chlororithra. Diagnoses for the genus and the species are provided and illustrations of external features and genitalia are presented.

Phyllanthus kaweesakii Pornp., Chantar. & J.Parn. sp. nov. is newly described from the limestone mountain ridges in the northeast of Thailand. Comparison of morphology, anatomy, pollen morphology, and DNA sequences of this species with the most similar existing species P. mirabilis Müll.Arg. was undertaken. The results indicated that the two taxa are different in morphology, especially habit, stem base, and inflorescence, but that their pollen morphology and anatomy are similar. The molecular phylogenetic analysis, based on sequences of the plastid matK and nuclear ribosomal ITS regions, supported separation of the two taxa. This new species is described and illustrated, and its conservation status is discussed.

Pilaira australis, a new species of fungus in the coprophilous genus Pilaira, was isolated from emu (Dromaius novaehollandiae) faeces and is described. Morphologically, the species resembles other species in the genus, particularly P. moreaui, except differs in its unique combination of sporangiophore height and sporangiospore length. Molecular phylogenetic analysis indicates that P. australis is distinct from other species in the genus with two regions, the internal transcribed spacers (ITS) and a fragment of the pyrG gene, showing 91% and 90% identity to the nearest species, respectively. Ultrastructure features and carbon utilisation were determined for P. australis, and may provide characteristics for species identification in this genus.

Codonopsis atriplicifolia (Campanulaceae) from western Sichuan, China, is described here as a new species, which is similar to C. subscaposa in a number of characters. The results of molecular phylogenetic analysis of 25 species of Codonopsis based on chloroplast DNA fragments (matK, petD with petB-petD, rbcL) show that C. atriplicifolia is closely related to C. farreri. In morphology, the new species is distinctly different from the allied species by its linear-lanceolate leaves with subentire to pinnatipartite margins.

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.
