5A597B55FFCF772CA9C5FF00FCCEFE09.taxon	discussion	A morphological comparison was made between Perakanthus longipetalus and Perakanthus velutinus (formerly the single known species in the genus) to demonstrate that they are sufficiently different (Table 1). Perakanthus was previously thought to be endemic to Peninsular Malaysia (southern Kedah, Perak, and Johor states) (Puff & Wong 2005), and the discovery of Perakanthus longipetalus in northern Myanmar is a significant extension of its geographic range, suggesting that there could possibly be other overlooked species of the genus in the region.	en	Neo, Louise, Mahyuni, Ridha, Wong, K.
