Generic recircumscription in the Loxocarpinae (Gesneriaceae), as inferred by phylogenetic and morphological data

12 The Loxocarpinae, also known as the “Boea group”, are the subtribe of Gesneriaceae 13 which includes Boea and a number of segregated genera and close relatives. This group 14 currently comprises over 200 species in 15 genera. Here we present the most up-to-date 15 phylogeny, covering all the genera known to belong to the group, based on Bayesian 16 Inference and Parsimony of the nuclear ITS and the plastid regions trnL-trnF (intron 17 and spacer) and ndhFtrnL (spacers). The results show discrepancies between the 18 current generic delimitation in the subtribe and the clades delineated by the phylogeny. 19 As a result Boea, Damrongia, Streptocarpus and Paraboea are recircumscribed in an 20 attempt to establish a more natural classification and a number of new combinations are 21 made. The new genus Middletonia is described. 22

Chayamaritia (Gesneriaceae: Didymocarpoideae), a new genus from Southeast Asia

Based on a phylogenetic analysis of Asian Gesneriaceae with the most comprehensive coverage at the genus level to date, the new genus Chayamaritia is established and described in subfamily Didymocarpoideae, tribe Trichosporeae, subtribe Didymocarpinae. It contains two species, of which one, Chayamaritia smitinandii (B.L.Burtt) D.J.Middleton, was formerly placed in the genera Chirita and Henckelia. The other, Chayamaritia banksiae D.J.Middleton, is newly described. The exclusion of Chayamaritia smitinandii from Henckelia further clarifies the taxonomic and biogeographic limits of Henckelia following its considerable recircumscription during the recent remodelling and synonymisation of Chirita.

Four new species of Microchirita (Gesneriaceae) from Thailand

SummaryFour new species of Microchirita (C. B. Clarke) Yin Z. Wang are here described: M. huppatatensis C. Puglisi and M. personata C. Puglisi, from Uthai Thani province, and M. hemratii C. Puglisi and M. lilacina C. Puglisi, from Tak province. Proposed conservation assessments are given for all species.
