Note : — In my former list of the plants of Aden I combined Schwein- 
f urthia pedicellata Renth. Sc Hook, with S. pterosperma ; but there seems 
to he no doubt that these two names represent two distinct species. Yatke 
wrote in 1875 (Plant® in itinere Africano ab J. Al. Hildebrandt collect®, 
in Oesterr. Bot. Zeitschr. XXY. Jahrg. (1875) p. 96) : Antirrhinum 
apterum Yatke. [= Schweinf urthia apter a Yatke] “ ab affini A. pteros- 
permo A. Rich, vel Schweinf urthia p. A. Br. seminibus eximie differ!.^ 
3. Anticliaris Endl. 
Dwarf erect herbs with glandular pubescence. Leaves entire. 
Peduncles axillary, solitary, 1-flowered, often with 2 small bracts.
