Monadenia with Disa. I would keep it a sectional group, and 
include in it D. tenuis, Lindl., with its single pollinary gland. 
Brownleea was established by Harvey in 1842 upon two eastern 
Cape species ; and is chiefly distinguished from Disa by its side 
petals being adnate, or at least permanently adhering, to tho 
galeate back sepal, and its labellum expanded at base into a pouch- 
like process embraeing the column, aud the limb upturned and 
reflexed over the stigma. Harvey pointed out its affinity with 
Disperis, which is very eurious. By an unfortunate error, the 
galea is described in the * Genera Plantarum,’ Benth. & Hook. f., 
as spurless, besides some other discrepancies which lead one to 
think that the manuseript must have suffered some accidental 
change which eseaped revision. Prof. Reichenbach has reduced 
this genus to Disa (Otia Bot. Hamburg, fasc. ii. part 1, p. 119), 
without giving any reasons for this step. I have only examined 
the flowers of three species freshly preserved in aleohol. These 
fully bear out the generic characters assigned by Harvey. I 
know of nothing approaching them in Disa, and they seem to 
me sufficiently valid. Without knowing every species of the 
genus, I would not challenge the conclusions of so experienced 
an authority ; but without further knowledge I am not prepared 
to adopt them.
