This species is portrayed in Bot. Mag., n.s., t.832. In the accompanying article Nigel Taylor points out that M. trifolia was the name originally given to this species. Later Schlechtendal illegitimately altered the specific epithet to schiedeana for fear of confusion with M. trifoliolata.
The plant figured in the Botanical Magazine was raised by Brian Mathew from seeds collected by Mrs S. Walker at about 13,000 ft on Ixtaccihuatl in the state of Mexico in 1970, and has proved hardy in a garden in North London. When ten years old it had reached a height of only 1 ft or so.
