Recircumscriptions have led to quite radical redefinitions and/or expansions of some genera (e.g., Deinostigma, Oreocharis, Petrocodon, and Primulina).…”

In recent years significant advances have been made in the taxonomy and classification of the Gesneriaceae, mostly based on molecular-phylogenetic research. This has led to major changes in the classification of the family and the establishment, reestablishment, recircumscription and synonymisation of many genera. Consequently, the treatment of the Gesneriaceae that was published in Kubitzki's Families and Genera of Vascular Plants, with brief descriptions and keys to all genera as well as the formal and informal groups of Gesneriaceae then recognised, has become rather out-of-date in a relatively short period of time. In 2013, a new formal classification of Gesneriaceae was published, with inclusion of Sanango in a third subfamily, reclassification of Gesnerioideae and de-novo-classification of Didymocarpoideae. In the present paper an effort is made to survey all of the taxonomic changes in the Gesneriaceae since the publication of these two treatments. This is done at all levels of the taxonomic hierarchy down to the genus level and new keys for the identification of the current infrafamilial taxa and genera are provided. As the taxonomic concepts of most genera are based on a combination of vegetative, floral and fruit characters, having fertile material is still a prerequisite for unambiguous identification. A glossary is provided to explain botanical terms largely specific to Gesneriaceae taxonomy.

“…Although it is not surprising that a family such as the Gesneriaceae, already known for having large numbers of locally endemic species in other parts of Southeast Asia, should be particularly poorly represented in a region of low collecting density, the contrast here between the Apocynaceae and Gesneriaceae may point to there being Weber & Burtt (1998), Hilliard & Burtt (2002), Hilliard (2004), Middleton (2007Middleton ( , 2009aMiddleton ( , 2016, Xu et al (2008), Anderson & Middleton (2013), Middleton et al (2014Middleton et al ( , 2015, Bransgrove & Middleton (2015), Puglisi & Middleton (2017a, 2017c, 2017d.

is a region of high plant diversity with an estimated 50,000 flowering plant species. Estimates of plant diversity in the region continue to grow as large numbers of new species are described even though there have been suggestions that there are few new species to be Gard. Bull. Singapore 71 (2) 2019 268 found in some parts of Southeast Asia. It is likely that most estimates of species numbers in the countries of Southeast Asia are too low due to the lack of taxonomic work on groups which have many locally endemic species. Differing collecting densities across the region can profoundly affect our understanding of plant diversity and lead to large underestimates of species diversity in poorly collected countries and regions.

“…This has entailed a deep reconstruction of the subfamily that is still in process, allowing more homogeneous species classification [1,[13][14][15]. Some genera have been newly established (Billolivia, Michaelmoelleria, Chayamaritia, Glabrella, Microchirita, Middletonia, Rachunia, Somrania) or recovered (Dorcoceras, Loxocarpus), while others have gained species from other genera (Damrongia, Oreocharis, Loxostigma, Deinostigma, Paraboea, Primulina, Streptocarpus), lost species by relocation to other genera (Boea), or lost species by synonymization (Acanthonema, Hovanella, Colpogyne, Linnaeopsis, Nodonema, Schizoboea, Briggsia) [13,[16][17][18][19][20][21][22][23][24][25][26][27][28].…”

Gesneriads, a Source of Resurrection and Double-Tolerant Species: Proposal of New Desiccation- and Freezing-Tolerant Plants and Their Physiological Adaptations

Gesneriaceae is a pantropical family of plants that, thanks to their lithophytic and epiphytic growth forms, have developed different strategies for overcoming water scarcity. Desiccation tolerance or “resurrection” ability is one of them: a rare phenomenon among angiosperms that involves surviving with very little relative water content in their tissues until water is again available. Physiological responses of desiccation tolerance are also activated during freezing temperatures, a stress that many of the resurrection gesneriads suffer due to their mountainous habitat. Therefore, research on desiccation- and freezing-tolerant gesneriads is a great opportunity for crop improvement, and some of them have become reference resurrection angiosperms (Dorcoceras hygrometrica, Haberlea rhodopensis and Ramonda myconi). However, their difficult indoor cultivation and outdoor accessibility are major obstacles for their study. Therefore, this review aims to identify phylogenetic, geoclimatic, habitat, and morphological features in order to propose new tentative resurrection gesneriads as a way of making them more reachable to the scientific community. Additionally, shared and species-specific physiological responses to desiccation and freezing stress have been gathered as a stress response metabolic basis of the family.
