Mycoheterotrophic Plants

How many of them are there?

Erythrorchis altissima (Blume) Blume 1835

Erythrorchis altissima was shortly described by Blume (1825) as Cyrtosia altissima. Blume (1835) himself transfered it later to the genus Erythrorchis and added a formal description. He found the species in western provinces of Java, which mark a southern boundary of the distribution that we know today. Erythrorchis altissima grows in secondary lower montane forests, on tall trees at elevations of 300 to 900 meters (Pfahl 2020) and can be found from Japan to Taiwan, Vietnam, Bangladesh and includes many islands of the Phillipines, Malaysia and western Indonesia (PWO). This plant is climbing in trees and forms small, up to 1,5cm big white to yellowish flowers (Chen et al. 2009). Garay (1986) sees in Erythrorchis ochobiensis due to "rather slender to almost filiform fruits, in addition to the mutually exclusive distribution pattern" a seperate species. Merckx 2013 also acknowledges E. ochobiensis as a species. Furthermore Umata (1995, 1997, 1998) found for E. ochobiensis that the mycorrhizal partners are comprised of a wide range of wood-rotting and ectomycorrhizal fungi species.
