ASCLEPIADACE^ AFKICAN^ 343 



6'5 mm. long., illius lobi laterales 2-5 mm. long. Columna 

 staminea 5 mm. long. ; antherarum alae 2 mm. diam. Pollinia 

 oblongo-pyriformia, 1 mm. long ; glandula 1 mm. long., caudiculis 

 aequilonga. 



Very distinct from all African species of the genus. The 

 corona in some respects resembles that of A. Bandii S. Moore, 

 but this is quite unlike in foliage and other characters.

Planta bispithamea vel paullo ultra. Internodia circa 6-10 cm. 

 long. Folia + 10 cm. long., 3-6 mm. lat., in sicco dilute virentia ; 

 petioli circa 3 mm. long. Spec, unici nobis obvii pedunculus 



13 cm. long. Pedicelli circa 1 cm. long. Flores pansi circa 3 cm. 

 diam. Calycis segmenta 5 mm. long. Corollae lobi 15 x 6 mm. 

 Coronae phylla 22 mm. long.; pars cucuUata 8 mm. long., juxta 

 medium 3*5 mm. lat., hujus cornua 3-5 mm. long. ; pars lorata 



14 mm. long., basi 2 mm., medio 1 mm., apicem versus -4: mm.

A very distinct species, with a corona much like that of 

 A. rohusta N. E. Br., but altogether different fohage.
