and more or less convolute, sometimes very brond and forming a tnhe inund both
flowers; the upper flower has often a sheathing obtuse bractC'ilc. — The genus wants
a careful study of living specimens. I am far from satisfied with the following

diagnosis.

is such a mixture of specimens in a very bad state under Wallich Ko. 1948 that a
