striate below, very thinly to rather densely pubescent with spreading 
hairs ; leaves of the main stems (including the 4-2 lin.-long petioles) 
4-11 in. long, }-% in. broad, those on the branches smaller, ovate or

tube, otherwise glabrous, pink (Thorncroft), lilac (Bolus) ; tube 
much exserted, }—3 in. long, very slightly curved, slender at the

obtuse middle lobe ; lower lip 3-5 lin. long, boat-shaped, obtuse ; 
stamens much exserted, very unequal, upcurved at the tips ; upper 
pair inserted at the middle of the corolla-tube, 7 lin. long, with free
