3. Two novelties allied to B. velutina (sect. Barleria)

– Barleria obtecta is very closely allied to B. velutina , and pertains to the same section, Barleria . The same holds for B. sceptrum­katanganum, allied to B. velutina by its hairiness and the shape of calyces and leaves; it differs by its strongly erect stem which is broader than in B. velutina , by its leafy spike, the leafy bracts hiding the calyx lobes which are not visible unlike in B. velutina , by the constant presence of the upper lobes of corolla, which are much larger than those of B. velutina when present in the latter, and by its considerably larger leaves.
