Epipactis magnibracteata C. Schweinfurth nom. 
nov. 
A mesia longibracteata C. Schweinfurth in Journ. Arn. 
Arb. 10 (1929) 172. 
Since the generic name Amesia A. Nels. & Macbr. was 
recently rejected by the International Botanical Congress 
of 1930 in favor of the conserved Epipactis Zinn, the 
transfer of Amesia longibracteata becomes necessary. 
The combination Hpipactis longibracteata appears to 
have been used by Wettstein in 1889, and accordingly 
the new specific epithet magnibracteata is proposed.

A comparison of Camaridiwm arachnites, as represented 
by an analytical drawing of the type made under the su- 
pervision of Dr. Schlechter, and a collection bearing the 
type number show that it is conspecific with Maaillaria 
ctenostachya as exemplified by a record of the type from 
the Reichenbachian Herbarium. 
In Camaridium arachnites the floral bract about twice 
surpasses the ovary, the flowers are described as white 
and the callus of the lip is shown as consisting of a sim- 
ple depressed apically dilated thickening. In Maaillaria 
ctenostachya, on the other hand, the floral bract is de- 
scribed as subequaling the ovary (but drawn as often 
much exceeding the ovary), the flowers are said to be 
ochre-colored and the callus consists of five approximate 
inconspicuous keels of which the three central ones con-
