Lissochilus and Eulophia, established by R. Brown, 

 mainly on characters of the lip, the one smooth the other 

 crested, now number between them about one hundred and 

 fifty tropical African species, and, altogether, nearly three 

 hundred species, very difficult to allocate between the two 

 proposed genera. Mr. Rolfe (Fl. Trap. Aft: vol. vii. p. 70), 

 notes that Lissochilus " approaches Eulophia very closely, 

 but the majority of the species are very easily separated 

 by the small spreading or reflexed petals [sepals], and the 

 broad, often differently coloured petals." And he retains 

 purpuratus in Lissochilus, though it is not one of those 

 easily separated from Eulophia, as it has similar sepals and 

 petals and a crested lip. However, as Lissochilus is the 

 older genus there is no question of a transfer here.
