206 THE JOUKNAL OF BOTANY 



Belgkn Congo, Kundelungu, under trees; Kassner, 2728. 



Planta saltern sesquispithamea forsan altior. Folia subtus ele- 

 ganter reticulata, suramum 8'5 X 1"5 cm., exstant vero minora 

 (e.g. 3x 1"3 cm.) majoribus per paria interposita, exemplarii alterius 

 nobis obvii folia magna pro parte alterna necnon modo 5-8 mm. lat. 

 Pedunculus saltem 2-5 cm. long., nonnunquam revera 8 cm. adajquans. 

 Capitula profeeto pansa 2 x 1*5 cm. Involucri phylla interiora apice 

 purpureo-membranacea, extima 6 mm., intermedia 8-9 mm., intima 

 12 mm. long. Corolla; tubus subcylindricvis, 5'5 mm. long. ; lobi 

 lineares, tubo cireiter jequilongi. Styli rami 3 mm. long. Achsenia 

 3 mm. long., pappi set?e 1'5 mm. 



E. monocephala Muschler, founded on a Congo plant {Kassner, 

 2183) unknown to me, must be near to this, but is described as having 

 different leaves and involucres.

 Oossweiler, 2877. 



Folia 5-8 cm. long., dimidio apicali usque 6-8 mm. lat., inferne 

 modo 1 mm. Scapi bractese stepius circa 10 mm. long. Corymbus 

 8x3 cm. Pedunculi proprii summum 6*5 cm. long., exstant breviores 

 8-25 mm. long. Capitula pansa 8x9 mm. Involucri phylla extima 

 2-2"5 mm,, intermedia 4 mm., intima 5 mm. long., omnia costa sat

 set?e 25-4 mm. long. 



Habit much that of V. prcemorsa Musciiler and its allies, but 

 these belong to another section of the genus.
