Hab. North Kamerun, Garua to Golombe; P. A. Talbot, 1005. 



Branches slender, white, with narrow herbaceous wings barely 1 mm. wide. Leaves up to 25x4 niiii., 

 those on the branchlets usually reduced to about 10x2 mm. Glomerules about 10 mm. in diameter, composed 

 of a large number of capitula. Peduncles at most 5 mm. long. Outer bracts 3-4 mm. long, 2 mm. at the widest 

 part, firm in texture, greyish-green when dry. Bracts of the capitula 3-5 mm. long, -VO mm. broad, somewliat 

 cymbiform, provided ivith short stiff hairs near the apex on the outer side. Involucral leaves 3 mm. long, like 

 the brarts scarious. Corollas of the hermaphrodite florets pale purple, 1-5 mm. long, the same length as those 

 of the filiform female florets, which stand on exceedingly slender pedicels 1-1 -5 mm. in length. Young aehenes 

 2 mm. long, papillose. Achenes of the female florets 1 mm. long, covered with spreading hairs. 



This might be mistaken on a fust sight for Sph. pediincxdaris DC, which, inter alia, has 6-leaved involucres. 

 Its position in the genus is near Sph. Utectzii O. & H.
