Bulbophyllum cryptomeriicola T.P. Lin & S.K. Yu, sp.
nov.
Diagnosis: Among the species of the group of
Bulbophyllum hirundinis, listed above, B.
cryptomeriicola is uniquely characterized by the
rhizomes which are suspended in the air but are not
prostrate on bark and are supported by thick, erect roots.
B. cryptomeriicola also differs from each of the species
above as follows: from B. hirundinis and B. hirundinis var.
calvum by shorter inflorescence and white cilia along
perianth; from B. taiwanense by shorter inflorescence,
white cilia along perianth and folded along midvein at the
basal lateral sepal. B. crytomeriicola may also look
similar to B. kuanwuense and B. albociliatum var.
remotifolium, because of similar flower color, but differs
from B. kuanwuense by longer peduncle, longer and
tapering lateral sepal (see also Table 1), and from B.
albociliatum var remotifolium by much thick rhizome,
thick peduncle, rough surface on and tapering lateral
sepals. B. albociliatum var remotifolium has filament-like
rhizome and peduncle.
Distribution and Ecology: Endemic to Taiwan. This
species grows in clumps on conifer trunks at an elevation
of 2200 m. The growth habitat is similar to that of B.
kuanwuensis S.W. Chung & T.C. Hsu which has a very
short inflorescence, shorter than 2 cm long (Table 1).
Etymology: The scientific name refers to the fact that
the species grows as an epiphyte on Cryptomeria
japonica (Thunb. ex L.f.) D.Don.
