Globba philippinensis Naive, J.A.G. Dalisay, Bangcaya
& Sangvir., sp. nov.
Diagnosis: Globba philippinensis Naive, J.A.G.
Dalisay, Bangcaya & Sangvir. is similar to G.
campsophylla K.Schum. (Fig. S1A) and G. argyrocycnos
Sangvir. & M.F.Newman (Fig. S1B) in floral structure
and flower colour, respectively. Similar to Globba
campsophylla K.Schum. in its decurrent labellum, base of
filament with cornicula, and linear lateral staminodes but
differs in its contrasting flower colour of yellowish
orange (floral tube, corolla lobes, lateral staminodes, and
labellum lobes) and white (filament and anther thecae)
(versus flower pure white with yellow spot at labellum)
and bulbils produced at peduncle (versus at tip of the
inflorescence). Similar to Globba argyrocycnos Sangvir.
& M.F.Newman in its contrasting flower colour of
yellowish orange (floral tube, corolla lobes, lateral
staminodes, and labellum lobes) and white (filament and
anther thecae) but differs in its decurrent labellum base
with cornicula (versus decurrent labellum base on
filament without cornicula).
