between them about half that diameter ; nodes and inter- 
nodes with shallow distant grooves; the upper half of each 
node is covered with a scarious appressed sheath ; colour pale

pairs ; white with broad rosy tips to the sepals, petals, and 
lip, and a yellow disc to the latter. Sepals linear-oblong, 
acute or subacute. Petals similar, but much broader. Lip 
very broadly ovate-oblong, obtuse, undivided, shortly clawed ; 
margin minutely erose and ciliate ; upper surface covered 
with a fine velvety down. Column short, white in our spe-
