During field work by the fi rst author at
Khlong Lan waterfall in Kamphaeng Phet in 2009,
an undescribed, lithophytic species related to
Damrongia purpureolineata Kerr ex Craib was
found growing luxuriantly on the wet granitic
rocks. The genus Damrongia (Gesneriaceae) was
fi rst proposed by Kerr in Craib (1918) to honour
H.H. Prince Disakumara Krom Phraya Damrong
Rachanuphap (1862–1943) of Thailand.
