Biermannia longicheila (Orchidaceae, Aeridinae), a new species from southern Vietnam

Abstract

Biermannia King & Pantling (1898a: 591) comprises about ten species distributed from northeastern India and southern China through the Indochinese and Malay Peninsulas to Sumatra, Java and Borneo (Comber 1990, 2001, Seidenfaden & Wood 1992, Pearce & Cribb 2002, Chen & Wood 2009, Chase et al. 2015). All species of this genus are miniature, canopy epiphytes with small, unattractive fugacious flowers lasting only few hours in the morning. As a result, representatives of this genus are easily overlooked in botanical surveys, poorly represented in herbaria and remain infrequently inventoried in local floras throughout its range. One more new species that differs strikingly from all hitherto known species of this genus was recently discovered in southern Vietnam. Here we describe and illustrate this unusual plant.

“…bimaculata (King & Pantl.) King & Pantl (King and Pantling, 1898, Pridgeon et al., 2014, Averyanov et al., 2018b), the new species, however, differs from its with 25–35 pale brownish calluses on inside surface of the lip (vs. lip with 2 calli at base and 2 calli at base of mid lobe). Additionally, B .…”

“…Biermannia has 11 species distributed from Northeastern India to Java and Sumatra through Thailand, Indochina, Malaysia, Singapore and Indonesia (Seidenfaden, 1988, Seidenfaden, 1992, Seidenfaden and Wood, 1992, Rao, 2006). Two species have been described new to science from Vietnam recently (Averyanov et al., 2018a, Averyanov et al., 2018b). All species of this genus are miniature, canopy epiphytes with small, unattractive fugacious flowers, and so are easily overlooked in botanical surveys (Averyanov et al., 2018b).…”

“…Two species have been described new to science from Vietnam recently (Averyanov et al., 2018a, Averyanov et al., 2018b). All species of this genus are miniature, canopy epiphytes with small, unattractive fugacious flowers, and so are easily overlooked in botanical surveys (Averyanov et al., 2018b). One potential new species of Biermannia was recently discovered in Northern Myanmar, representing a newly recorded genus to the Orchid Flora of Myanmar.…”

Phylogenetic position and plastid genome structure of Vietorchis, a mycoheterotrophic genus of Orchidaceae (subtribe Orchidinae) endemic to Vietnam

“…Ten years after the publication of the genus, its second species, V. furcata Aver. & Nuraliev, was described (Averyanov et al, 2013; see also Averyanov, 2013;Nuraliev et al, 2019). After another ten years, the third species of the genus, V. proboscidea Aver., Vuong & V.C.Nguyen, was introduced, which is extremely close morphologically to V. furcata (Averyanov et al, 2023).…”
