 2-3 m. high, aromatic, flowers violet, 840 m., June 20, 1946, 16370. Kota-kota

 shrub 1.5-2.5 m. high, aromatic, flowers dark purple,, conspicuous, 1400 m., July 

 24, 1946, 16903. Nyasaland and N. Rhodesia, with very close relatives as far

Englerastrum hjalmari T.C.E.Fr. Notizbl. Bot. Gart. Berlin 9: 71. 1924. 

 Englerastrum kassneri T.C.E.Fr. Notizbl. Bot. Gart. Berlin 9: 70. 1924. 

 Plectranthus kassneri (T.C.E.Fr.) Hutch. & Dandy, Kew Bull. 1926: 481. 1926. 

 Plectranthus hjalmari (T.C.E.Fr.) Hutch. & Dandy, Kew Bull. 1926: 481. 1926. 



Kota-kota District: Nchisi Mountain, on now dry seepage-slope in Brachy~ 

 stegia woodland, gregarious, 20-40 cm. high, flowers blue, 1400 m., July 25, 

 1946, 16935. Belgian Congo, southwestern Tanganyika Territory, N. Rhodesia, 

 and now new to Nyasaland. 



We are keeping this in Englerastrum in view of its habit and corolla, rather 

 than in Plectranthus as Hutchinson and Dandy do, or in Coleus as Robyns and 

 Lebrun advocate. The additional specimens now available lead us to believe that 

 E. kassneri and E. hjalmari are merely different stages in development of the same 

 species, in which the frui ting-calyx is strongly accrescent (Miss E. A. Bruce and 

 J. P. M, Brenan).
