Abstract:Two Paraboea species,P.neurophylla and P.thorelii,are reported for the first time ftom Vietnam.The
citation of specimens and their distribution is given in the present paper.
Key words:Vietnam;Gesneriaceae;Paraboea;P.neurophylla;P.thorelii
According to the latest revisions and publications
of the genus Paraboea(C.B.Clarke)Rid1.comprises 94
species distributed in Bangladesh,Bhutan,Burma,
Cambodia,southern China,India,Indonesia,Laos,Ma—
laysia,Philippines,Thailand and Vietnam(Kiew,2010;
Wei et a1.,2010;Chen et a1.,2008;2011;Xu et a1.,
2008).In Vietnam,only fifeteen species are recorded
(Xu et a1.,2008). We collected many specimens of
Paraboea from al parts of Vietnam. W e carefully
compared their morphology,both of reproductive and
vegetative organs.Especially the characteristics of the
reproductive organs are important for species identifi—
cation.During the study of specimens and literature of
Gesneriaceae from Vietnam,we have found two new
records of species of Paraboea(C.B.Clarke)Rid1.for
the flora of Vietnam.They are P.neurophylla and P.
thorelii.Up to now,Paraboea are recorded with sev~
enteen species.
