Finding
The color of the flowers in the photos was not accurately captured; the color on the distal portions of the segments was described as being much more suffused with brown, instead of the bright red shown. There is photo by Grobler which shows this brownish coloration in the OW. M. grandiflora is a giant among the Genus; this is a large plant meeting the description of an enormous species; flower form appears correct, as does the yellow callus that runs the length of the midlobe. Flower size is also large at 7.2 cm. Many supporting photos can be found in the orchichroots.com and the IOSPE and other on-line sources.
