“…In addition to the liana habit, Friesodielsia can also be circumscribed by the presence of (1) a more or less glaucous lower leaf surface, (2) a usually obvious pair of glands at the base of each leaf blade, (3) initially terminal inflorescences developing to become internodal (or sometimes leaf-opposed), (4) inner petals that are smaller than the outer petals and remain connivent at maturity and (5) usually single-seeded monocarps (e.g. Leeratiwong & al. 2021a).…”

Molecular phylogenetic and morphological support for the recognition of Friesodielsia lalisae (Annonaceae), a new species from S Thailand

Thirteen species of Friesodielsia Steenis (Annonaceae) and 11 representatives of related genera were included in molecular phylogenetic analyses using up to six plastid DNA regions (psbA-trnH, trnL-trnF intergenic spacers; trnL intron; matK, ndhF, rbcL exons). The results support the recognition of a new species, F. lalisae Damth., Baka & Chaowasku from Narathiwat, S Thailand, as belonging to one of the two major clades of Friesodielsia. The members of this clade show outer petals that separate at anthesis and have a concave basal portion, while members in the other major clade exhibit outer petals that separate early during developmental stages and have a flat base. Friesodielsia lalisae is described and illustrated. It is most morphologically similar to F. argentea (J. Sinclair) Steenis and F. glauca (Hook. f. & Thomson) Steenis but differs from the two by having dissimilar sepal shape, higher proportion of inner petal to outer petal length and longer inner petals. The new species additionally differs from the former by having different leaf base and from the latter by having denser indumentum on young twigs and shorter flowering pedicels. Narathiwat, a province to which the new species is endemic, seems to be one of the most underexplored areas in Thailand as evidenced by a number of species described based on recent material. The conservation status of the new species is provisionally assessed as Critically Endangered.

During botanical expeditions focused on the study of Annonaceae in Thailand, specimens resembling Friesodielsia glauca were collected from the lower part of peninsular Thailand but were believed to differ from that species in vegetative, flower, and fruit characters. A morphological investigation of the new specimens and species complex was conducted. Specimens (including types of F. glauca and similar species collected from Thailand and adjacent regions) were examined in the following herbaria: A, BK, BM, BKF, E, K, KEP, KKU, L, PSU, QBG, SING, and US. As a consequence, the new species Friesodielsia parvimitra, endemic to peninsular Thailand, is described and illustrated. The conservation status of the new species was provisionally assessed as Critically Endangered (CR, B2ab(iii)) following the IUCN’s guidelines. In addition, F. argentea, previously regarded F. glauca, is reinstated here as a distinct species based on several morphological differences and is reported as a new record from Thailand. Photographs, line drawings, and a revised key to F. glauca and similar species are presented.
