According to Mrs. Barber’s note with the specimen the flowers are ‘ dark 
brown and green.” She states that “it is very uncommon; I have only seen 
this one plant.” Allied to .X. brownianwm, but differs in its corona-lobes, 
anther-wings and locality.

13-10 lin. broad, linear, linear-oblong, or narrowly lanceolate, acute, 
cuneate or rounded at the base, where they somewhat abruptly curve 
upwards into an erect position, crisped on the slightly scabrid
