The freshly found plant Relictithismia kimotsukiensis most likely diverged at an early stage in the development of the entire household and retains ancestral qualities. This history is reflected in the plants name. Credit: Suetsugu KenjiA brand-new species and genus of fairy lantern, small glass-like white plants that eat fungi, has been discovered in Japan. In the nation renowned for its extensive flora research study, the discovery of a brand-new plant genus is very rare and has actually not happened in almost 100 years.Fairy lanterns, or Thismiaceae as they are understood to botany, are very uncommon plants found mainly in tropical but also in temperate and subtropical regions. Of all, they are not green and do not engage in photosynthesis, but rather feed on fungal mycelia in the ground. As an effect, they are often hidden under fallen leaves and only for a short period produce above-ground flowers that look like glasswork.The Japanese name for Thismia, one of the significant groups within this family, is “Tanuki-no-shokudai,” which means “raccoon pets candleholder” and refers both to their shape and their underground lifestyle. They are also extremely unusual and challenging to find.Discovery and Research”At present, around 100 species within the family have been identified, nearly half of which are understood just from their very first discovery, often from a single specimen,” discusses Kobe University botanist Suetsugu Kenji, who is a worldwide renowned professional on non-photosynthetic plants.One of the most intriguing distinct attributes of the newly explained Relictithismia kimotsukiensis is that its stamens (the male part of the plant) touch the stigma (the female part), hence assisting in self-pollination. This adjustment is most likely useful for a plant that lives under fallen leaves in dark forests where pollinators are scarce.

He says, “The devotion of Japanese amateur scientists to exposing the covert flora of these regions has been important in recognizing types unidentified to science.” Therefore, when he was sent out a specimen of a fairy lantern that a hobby botanist had found which a local professional believed represented a new species of the genus of Tanuki-no-shokudai, he understood he needed to investigate.However, it soon became clear “that this plant was not consisted of in any of the existing genera (such as Thismia) because of its distinct features, and it ended up being needed to get additional people for additional examination.” So, he went to Kimotsuki in Kagoshima Prefecture, where the discovery had been made, but could not discover any other samples. A year later he tried again and got lucky: They discovered four more plants, all in the exact same narrow area.The analysis of the freshly found Relictithismia kimotsukiensis revealed that it is various enough from all understood genera of Thismiaceae to require its category as a totally new genus. “Our competence in various aspects of botany enabled us to combine traditional taxonomic techniques with contemporary molecular techniques, providing a thorough approach to our research study,” states Kobe University botanist Suetsugu Kenji.

Based both on morphological and genetic analysis, the team concluded that the plant is not just a brand-new species, however in truth different enough from Tanuki-no-shokudai to be a different genus– the next level of relationship above species.The researchers believe the plant probably diverged at an early phase in the development of the entire Thismiaceae household and maintains qualities that prevail to the household but have been lost in the Thismia genus. This is the reason Suetsugu chose the name “Mujina-no-shokudai,” or “badgers candleholder”: “Mujina” is an old Japanese word for a badger, but often has likewise been used for the raccoon dog which it resembles but is various from. Therefore, the name shows the plants relationship with Thismia. The Latin name Relictithismia kimotsukiensis is similar, as it can be equated as “Thismia relict of Kimotsuki.”Members of the household Thismiaceae feed upon fungal mycelia in the ground. As an effect, they are frequently concealed under fallen leaves and just for a brief period produce above-ground flowers that appear like glasswork.

In truth, the last discovery of a brand-new vascular plant simultaneously recognized as a separate genus was the discovery of Japonolirion in 1930, nearly 100 years back. Suetsugu discusses, “This research may suggest that numerous other new species may be hiding in areas formerly believed to be well-studied and underscores the important requirement for continuous expedition and examination of the worlds plants both abroad and at home.”A plant that feeds on fungi and is so restricted in its local spread is also remarkably vulnerable to ecological change. This inspires Suetsugu to deepen his research, stating, “A section of our future research will be committed to eco-friendly research studies targeted at analyzing the interactions in between Relictithismia and its fungal hosts, in addition to assessing the impact of ecological alterations on these associations.”Reference: “Relictithismia kimotsukiensis, a brand-new genus and types of Thismiaceae from southern Japan with conversations on its phylogenetic relationship” by Kenji Suetsugu, Yasunori Nakamura, Takafumi Nakano and Shuichiro Tagane, 29 February 2024, Journal of Plant Research.DOI: 10.1007/ s10265-024-01532-5This study was supported by the PRESTO program (grant JPMJPR21D6) of the Japan Science and Technology Agency, the JSPS KAKENHI (grant 21K06307), and the Environment Research and Technology Development Fund (grant JPMEERF20204001) of the Ministry of the Environment, Japan.
