Kenji Suetsugu, a specially appointed lecturer at the Graduate School of Science, Kobe University, Yuichi Fukunaga, a plant researcher in the field, Tomoe Shimaoka, a graduate school of natural sciences at Kumamoto University, and Shinichiro Sawa, a professor at the Graduate School of Advanced Sciences, Kumamoto University, have been It was revealed that the plant listed in the pictorial book as the orchid plant "Kurokuroyoran" was actually another plant called "Tosanokuromuyoran".
This time, in the process of working on the distribution survey, the research group noticed that the Lecanorchis japonicus plants distributed in limited areas such as Miyazaki and Kochi prefectures bear fruit with hard buds without flowering even once.As a result of further investigation, this plant that does not bloom is the "real" chrome yoran, and the "blooming" "chrome yoran" (widely distributed from Honshu to Kagoshima) currently listed in the botanical pictorial book is " It was revealed that it was "Tosanochromium yoran".
Why did this misunderstanding happen?Mr. Kan Sawa (former assistant professor of Kochi University), the father of Professor Shinichiro Sawa, announced in 1981 the blooming chrome yoran (special in Kochi prefecture) collected in Kochi prefecture as "Tosano chrome yoran".However, there was no description describing the morphological characteristics of "Tosanochromium yoran" other than the presence or absence of flowering, and around the time of his announcement of Tosanochrome yoran, the chrome yoran that blooms in multiple pictorial books is "Chromium yoran". It seems that this misunderstanding was caused by the widespread recognition that chrome yoran is a flowering substance.
This time, the name "Chromium yoran" is given to something that does not bloom, and there is no morphological difference between "Tosano chrome yoran" collected in Kochi city and chrome yoran that blooms in other places. , It became clear that the chrome yoran that blooms should be called "Tosano chrome yoran".
He also announced that the real "Chromium yoran" is a plant with a special ecology that does not bloom because it self-pollinates as buds.
Among plants, there are "fungal heterotrophic plants" that grow by taking in the hyphae of mushrooms and molds into the roots without photosynthesis and digesting them.Since this plant does not require photosynthesis, it appears on the ground only for a short period during the flowering and fruiting seasons, so there are many mysterious parts.
