Flora of the Malayan Pcninaula. 573 



flowers are "pearl-coloured," and this is what the Fl. Br. Ind. says of the corolla, 

 giving the corona-processes as " white with pink at the junctures." Maingay (MS. 

 Notes IV. p. 41) says, "petals white, faintly greenish towards the tips, corona white." 

 These remarks, for what seems clearly to be the same plant, explain the difference 

 between Lindley's and Paxtou's drawings alluded to in the Fl. Br. Ind. As remarked 

 in Fl. Br. Ind., H. cinnamomifoUa, Hook. Bot. Mag. 4347, from Java, " has very 

 similar flowers and leaves." But for the corolla being green and the corona purple in 

 that fig., we should be inclined to place it under H. parasitica.
