and the ladian one tero described. The genus was mniatained by the lato Mr, Bentham (Gon. Plantar.
I l l , 31á), but was iedueod by Sir J. D. Hookei- in liis Flora of British India to Eria, where "it was
I>laced in the section DendvoUrio'i. The latter o\ühor, ia describing tho Indian species as an Eria in
the Annals of tho Calcutta Gai'dsn (V, 22), suggested the probability of its having to bo removed from
that genus; and, in his Flora of British India V, 785, ho stated that, should an esamination of liviag
flowers prove the lip to be mobile, Tyloslylis ought to be rsinstatod as a gemis, Having satisfied '
ourselves that the lip is mobile, we aceoidingly adopt for the plant the name suggested for it by
him (Ann. Bot. Gard. Cale. V, 22).
