A parasitic weed of sorghums.
The plant has been noted growing in profusion on black, light alluvial soils near Kilosa. It appears under sorghum in April when the latter is beginning to flower. It is suspected that Zea and Vigna sinensis[Vigna unguiculata] are also host plants. The weed is semi-parasitic and apparently causes sorghum grain to be light and the heads poorly filled. Control methods recommended are early uprooting and burning before the seeds are set. The plant has recently been gazetted in Tanganyika Territory as a noxious weed.-M.H.
