  Similar to E. pyrophila but smaller. The relationship between the two needs investigating. Summerhayes (Kew Bull. 12: 125, 1957) stated: “I decided to treat this concept as conspecific…Further investigation, with information about the two plants in the field, has, however, led me to the view that it is better kept separate, as I had at first thought probable”. – Agnew (1994 & 2013 cited above) remarks that E. parvula was once found in Kenya in 1894, in similar habitats to E. pyrophila. – Eulophia parvula in I. la Croix & al., Orchids Malawi: 331, 1991, is E. pyrophila.
