VERNONIACE^ AFRICAN.^ NOV^ 97 



dilatatus; lobi oblongi, partis campanulatae dimidium adasquantes, 

 2-5 mm. long. Antheroe 4 mm. long., superne exsertoe. Stigmatis 

 rami 3-5 mm. long. Achuenia 3-5-4 mm. long. ; pappi setae 

 perpaucas exteriores 3-4 mm., ceterae summum 10 mm. long. 



Near V.pumila Kotsch. & Peyr., but with dissimilar coetaneous 

 leaves as well as different involucres. The allied species V. nan- 

 densis S. Moore has coetaneous but oblanceolate leaves, larger 

 heads and involucral leaves, &c. 



Vernonia (§ Stengelia) campicola, sp. nov. Caule erecto 

 crebro folioso angulato striatoque pubescente citissime puberulo, 

 foliis amplis sessilibus oblongo-obovatis obtusis dimidio inf. 

 gradatim attenuatis margine late dentatis membranaceis utrinque 

 scabriusculis, capitulis majusculis multiflosculosis paucis (exempl. 

 unici nobis obvii 4) ad apicem caulis corymbosis pedunculisque 

 validis pubescentibus suffultis, involucri subsphaeroidei phyllis 

 pluriseriatis interioribus gradatim majoribus chartaceis exterioribus 

 ovatis interioribus late oblongis omnibus appendice ovata obtusa 

 scariosa reticulato-nervosa onustis, corollis exsertis, achseniis 

 cylindricis basi callosis 8-costatis pubescentibus, pappi setis 

 aliquanto complanatis superne leviter dilatatis scabriusculis 

 rubiginoso-stramineis paucis exterioribus ceteris brevioribus.

Folia 18-23 x 3-5-6 cm. ; exstant vero minora, in sicco 

 brunneo-virescentia, subtus pallidiora ibique sub lente glandulis 

 lucentibus pilisque brevibus sparsim inspersa ; radicalia desunt. 

 Corymbus 5x9 cm. Capitula 3-5 x 4 cm. Involucri phylla 

 extima circa 10 mm., intermedia 15-20 mm., intima 25 mm. long. 

 Corollse tubus elongatus, angustus, apicem versus subcampanulatus, 

 27 mm. long., hujus pars amplificata 4-5 x 2-5 mm.; lobi oblongo- 

 lanceolati, 4 mm. long. Styli rami vix 5 mm. long. Achaenia 

 fere 2 mm. long. Pappi setae ext. + 6 mm., ceterae + 10 mm. 

 long. 



This belongs to the group of species clustering round V. in- 

 signis 0. & H. and V. Calvoana 0. & H. The foUage and achenes 

 are its chief peculiarities.

 ad apicem ramulorum solitariis breviter pedunculatis pedunculis 

 dense cinereo-pubescentibus, involucri campanulati phyllis circa 

 6-seriahbus interioribus gradatim paullo longioribus oblongis 

 humectatis crassiusculis appendice brevi herbacea oblongo-ovata 

 acuta onustis araneoso-pubescentibus, corolla3 tubo inferne 

 attenuate superne dilatata, antheris basi acutis, achaeniis oblongis

 18) 2-seriatis inferne subpaleaceis superne attenuatis valde 

 inaequalibus scabridis sordide albis.
