forest, in crevices of limestone rocks; 100 m. Hapaline kerrii
is known from only three collections and appears to be very rare
in Thailand. However, it might be that it is simply overlooked in
the field since the collections are quite widely scattered. The
Vamanonda 3 collection grew well at Kew for a number of years but
eventually rotted during the winter dormancy period. Collection
notes made by Mrs D.J. Collins on the Kerr 19462 collection state
'Perfume - musk eau de cologne... Stem indistinct mottling of pinky
grey and greyish white - sheath of stem pink'.
