Dalziel, 317; on rocky hills at Sokoto, sometimes planted near 
houses, native name “ Karan Masallachi,”” Dalziel, 367. 
Described from dried specimens and fresh material preserved in 
formalin. The fine and scanty pubescence on the inner face of the 
corolla-lobes is quite invisible on dried flowers that aa been boiled 
for dissection, until all moisture has evaporated from the surface. 
The long hairs fringing the lobes are also very nail detached, and 
in the specimens examined were mostly only to be found in unopened 
buds.

In gen neral appearance this plant much resembles Syncolostemon 
densiflorus, Benth., and when out of flower might possibly be 
mistaken for it, but the corolla, instead of having only 2 entire or 
slightly lobed lips, i is distinctly 4-lobed, one lobe forming the upper 
lip and three lobes forming the lower lip, so that it cannot be 
generically associated with either Syncolostemon or Orthosiphon. 
The tube of the corolla is unusually long.
