TL;DR: The polyphyletic genus Chirita is remodelled after an extensive molecular phylogenetic study of species assigned to it and to other associated genera and a general list showing the present accommodation of the species previously described under ChiritA, Chiritopsis, Hemiboeopsis, Primulina and Wentsaiboea is provided.
Abstract: The polyphyletic genus Chirita is remodelled after an extensive molecular phylogenetic study of species assigned to it and to other associated genera. Most of Chirita sect. Chirita and the monotypic Hemiboeopsis are amalgamated with Henckelia sect. Henckelia , resulting in a very differently circumscribed genus Henckelia and the synonymisation of Chirita. The remaining species of Chirita sect. Chirita are accommodated in the revived genus Damrongia. Chirita sect. Liebigia is recognised as the genus Liebigia. Chirita sect. Microchirita is recognised as the genus Microchirita. Chirita sect. Gibbosaccus is, together with Chiritopsis and Wentsaiboea , included in the originally monotypic and now enormously expanded genus Primulina. The necessary combinations are made and a general list showing the present accommodation of the species previously described under Chirita , Chiritopsis , Hemiboeopsis , Primulina and Wentsaiboea is provided.

TL;DR: Polyploid as well as dysploid changes appear to have shaped the genomes of the newly defined genera Henckelia, Microchirita and, to a lesser degree, Primulina.
Abstract: Chromosome numbers were determined in 23 accessions representing 21 species hitherto belonging to Chirita (Gesneriaceae), a genus that has recently been remodelled and split into five different genera: Damrongia, Henckelia, Liebigia, Microchirita and Primulina. The previously monotypic Primulina tabacum was also investigated. Counts for 19 species were new, two were confirmatory and two gave different numbers from previously published counts. The results here, together with previously published cytological data for the erstwhile genus Chirita, were analysed in the light of the taxonomic revision of the genus and published phylogenetic data. Chirita was originally highly heterogeneous in chromosome numbers, including seven different somatic numbers, 2n = 8, 18, 20, 28, 32, 34 and 36. Among the five remodelled genera, Henckelia was found to be as equally heterogeneous as the erstwhile Chirita, Microchirita included only two chromosome numbers, 2n = 18 and 34, the three species of Damrongia were uniform with 2n = 18, while species belonging to the extended Primulina showed only one basic number, x = 18, with 15 samples being diploid, and one being tetraploid. In the light of recent phylogenetic studies, polyploid as well as dysploid changes appear to have shaped the genomes of the newly defined genera Henckelia, Microchirita and, to a lesser degree, Primulina.

TL;DR: The taxonomic treatment includes a key for identification, detailed descriptions of the species, information on seed morphology, and a discussion on distributions, including maps, and the conservation status for each species.
Abstract: A revision of Microchirita (C.B.Clarke) Yin Z.Wang (Gesneriaceae) in Malaysia is presented as a precursory paper for the Flora of Peninsular Malaysia account. The taxonomic treatment includes a key for identification, detailed descriptions of the species, information on seed morphology (illustrated by Scanning Electron Microscopy micrographs), and a discussion on distributions, including maps, and the conservation status for each species.

TL;DR: Four new species of Microchirita (C. huppatatensis, hemratii, personata, lilacina and personata) are described from Uthai Thani province and Tak province, Thailand.
Abstract: Four 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.
