Theretore, the new combination Diothonea nutans is 
proposed. 
The concept, Mpidendrum rhopalorhachis, has already 
been referred to Hemiscleria nutans (Schlechter in Fedde 
Repert. Beih. 9 (1921) 145). 
As far as known, this species is restricted to Peru. 
Laelia moyobambae (Sch/tr.) C. Schweinfurth comb. 
nNOv. 
Schomburghia Moyobambae Schlechter in Fedde Re- 
pert. Beih. 9 (1921) 97; ex Mansfeld in Fedde Re- 
pert. Beih. 57 (1929) t. 128, nr. 482. 
In accordance with the recently suggested policy of 
including the concept Schomburgkia (1888) in the older 
genus Laelia (1831)', | hereby make the necessary trans- 
fers of this and the following Peruvian species: 
Laelia Weberbaueriana (A7iinz/.) C. Schweinfurth 
comb, nov. 
Schomburghia Weberbaueriana Kriinzlin in’ Engler 
Bot. Jahrb. 87 (1906) 527. 
Scaphyglottis Antonii Schlechter in Fedde Repert. 
Beih. 9 (1921) 78: ex Mansfeld in Fedde Repert. Beih. 
57 (1929) t. 115, nr. 453. 
Scaphyglottis loretoensis Schlechter in Fedde Repert. 
Beih. 9 (1921) 79 (as loretorensis): ex Mansfeld in 
Fedde Repert. Beih. 57 (1929) t. 116, nr. 454. 
Judging by a careful comparison of the type descrip- 
tions of these two concepts, the only difference between 
them lies in vegetative size. Whereas Scaphyglottis An- 
tonu is described as being 25-85 cm. tall with slender- 
cylindric stems up to 18 em. long, S. doretoensis is cited 
'L. O. Williams in Darwiniana 5 (1941) 74.
