ABSTRACT
Rhynchanthus bluthianus, from Mae Hong Son Province, is newly recorded for Thailand.
Keywords: Rhynchanthus, Zingiberaceae, Mae Hong Son, Thailand
Thailand.— NORTHERN: Mae Hong Son (Sob Moei).
Distribution.— Myanmar.
Ecology.— Epiphyte on tree trunk, montain forest, ca. 1,200 m alt.
Notes.— Two species of Rhynchanthus in Thailand belong to the few-flowered group. The major difference of both species is colour of flower. Rhynchanthus bluthianus
is distinguishable from R. longiflorus by its
pinkish white corolla and filament (vs.
yellow corolla and filament). Type specimen
of R. bluthianus is assumed (from the first
publication) to be deposited in the Botanischer
Garten und Botanisches Museum BerlinDahlem
(B) and may be lost in the fire of the
museum in 1943 (Dr. Robert Vogt, curator,
pers. comm.).
