Notes
A. ugandensis is a depauperate cultivated form with mostly 1-flowered inflorescences and almost entire leaves, slightly different in shape from those of A. hyoscyamoïdes. Napier 6106 is almost identical with the type of A. ugandensis. This species is closely allied to A. hyoscyamoïdes and replaces it at higher altitudes. It is possibly only an ecotypical condition, or a subspecies. A few complete intermediates are known from lower altitudes e.g. Jex Blake 5173 (Ol Lorgasailic), Beaton 26 (Mtito Andei), Scheffler 74 (Kibwezi) and Lea 39 (Rukwa) which have markedly lobed leaves but a finer indumentum.
