208 THE JOUJtNAL OF IJOTA^'V 



callosis 4-costatis appresse sericeis ; pappi ext. squamis abbreviatis 

 lineari-lanceolatis barbellatis int. setis scabribis albis. 



Belgian Congo, Mt. Senga ; Kassner, 2901. 



Folia summum 7-5 X 1'5 cm., pleraque ± 3'5 cm. x 8 mm., summa 

 pauca in bracteas transeuntia circa 2 cm. long. Corymbus circa 

 6x5 cm. Pedunculi proprii validi, plerumque l'5-3 cm. long. ; 

 bractese capitulum ipsmn attingentes 4- 1 cm. long. Capitula circa 

 12 X 13 mm. Involucri phylla extima 3 mm., intermedia 8 mm., 

 intima 9 mm. long. Corollte sparsim papillosae tubus inferne anguste 

 cylindricus superne anguste infundibularis, 5 mm. long. ; lobi vix 

 2 mm. Styli rami 2 mm., achsenia 1*25 mm., pappi squamae 1 mm. 

 et setae 6 mm. long. 



Allied to V. natalensis Sell. Bip., wlucb it closely resembles in 

 foliage, but differs from essentially in the capitula. 



Vernonia lavaiiduli folia Muschler in Herb. Berol. This nomen 

 nudum de Wildeman {I. c. p. 163) gives to Kassner No. 2522. This, 

 however, and No. 27'±2 are conspecific with No. 2777 described by me 

 ( Journ. Bot. 1914, p. 334) as V. oocephala Bale. var. angustifolia. 

 V. oocephala is a Tanganyika plant represented further west by this 

 palpable variety. 



Another Kassner plant (Ruzizi Valley, No. 3168) is apparentl}^ a 

 caulescent form of V. macrocyanus O. Hoffm. It is certainly not 

 V. Grantii Oliver as Muschler and Wildeman (/. c. p. 160) announce.

Khodesia, Sangolo stream vmder trees ; Kassneo', 2106. 



Folia summum 10 X 2 cm., sed infima et summa minora, in sicco 

 grisea. Corymbus circa 5x5 cm. Pedunculi proprii usque 3 cm. 

 lono-. Bractese capitula appropinquantes, lineares, circa 1 cm. long. 

 Capitula plene pansa 2x3 cm. Involucri phylla extima 5-7 mm., 

 intermedia 8-12 mm., intima 15 mm. long. Corollae sparsissime 

 papillosae tubus superne leviter dilatatus, 10 cm. long. ; lobi tubum 

 pemiaequantes. Styli rami 2 mm. long. Achsenia 6 mm., pappi 

 squamie 1-25 mm., setae pcene 10 mm. long. 



Affinity with V, henguellensis Hiern, but with several differences 

 in foliage and flowering heads.
