In van Beusekom’s 1971 revision (van Beusekom 1971) M. oldhamii (q.v.) is reduced to the status of M. pinnata subsp. arnottiana (Wight) van Beusekom var. oldhamii (Miq.) van Beusekom, a cumbersome name to say the least. This taxonomy has largely been superseded, with the result that M. pinnata (in the modern sense) is not represented in western gardens.
