cylindricis basi prominenter callosis rectis vel curvatis 5-costatis 

 angulatisque inter costas pilosulis glandulisque microscopicis 

 paucis lucentibus proiditis, pappi squamis anguste linearibus setis 

 levibus albis. 



Hab. Uganda, 100 miles N.W. of Kampala ; E. Brown 

 {Dilmmcr 2652). 



Folia 3-6 cm. long., 1-2-2-2 cm. lat., firme membranacea, supra 

 in sicco fuscescentia subtus grisea ; petioli usque ad 8 mm., dense 

 pubescentes. Panicula adusque 30 x 16 cm. ; hujus rami ascen- 

 dentes, inferiores fere 10 cm. long., omnes dense sed breviter 

 pubescentes. Cymae plerumque 5-6 cm. long., totidemque lat. 

 Involucri phylla extima 1-5-2-5 mm., intermedia 3-5-4 mm., 

 intima 6 mm. long. Corolla 8-5 mm. long., hujus tubus basi 

 brevissime angustatus ; lobi extus minute pellucido-glandulosi. 

 Styli rami exserti, 2-25 mm. long. Achaenia 1-25-1-5 mm. long. 

 Pappi squamae 1 mm., setae 6 mm. long. 



The stalked leaves obtuse at base, broader outer involucral 

 leaves, and smaller, angled achenes afford the best means of dis- 

 tinguishing this from V. usamharensis 0. Hoffm.

Hab. Uganda, savannah 100 miles N.W. of Kampala ; E. 

 Broivn [Dimmer 2656). 



Eolia + 5 cm. long., 2-3 cm. lat., firme membranacea, in sicco 

 supra olivaceo-fusca subtus ochraceo-grisea ; petioli 5-10 mm. 

 long. Panicula circa 15 x 12 cm. ; hujus rami ascendentes, 

 plerumque 2-4 cm. long. Peduncuh proprii summum 3 mm. 

 long., saepius vero etiam breviores. Capitula pansa 12 x 10 mm. 

 Involucri phylla extima 3-4 mm., intermedia 6 mm., intima 8 mm. 

 long. Corolla 9-5 mm. long. ; tubus inferne filiformis, superne 

 subito usque ad 1-2 mm., dilatatus. Styli rami exserti, 3 mm. 

 long. Achaenia matura basi levissime angustata, brunnea, 2 mm. 

 long. Pappus 7 mm. long. 



This is very near V. Kaessncri S. Moore, but its involucres are 

 different, having narrower leaves with a more pronounced appen- 

 dage. The corollas too are shorter and differently shaped, while 

 the achenes are broader and more markedly ribbed.
