ACANTHACEAX (S. Moore) 85 
exsertis antherarum loculis linearibus loc. inf. solum calcarato ; 
stylo apice 2-dentato puberulo ; capsula anguste obovoidea acuta 
superne puberula alibi glabra 4-sperma. 
North Nigeria, R. Benue. 
Leaves 8-5 cm. long, 4-8 mm. broad, drying green; petioles 
2-4 mm. long. Bracts in flowering stage 10 mm., in fruiting stage 
12 mm. long; bracteoles 2-2°5 mm. long. Limb of corolla purple. 
Segments of calyx in flower 6-8 mm., in fruit 8-10 mm. long. Corolla 
when moistened 28 mm. long; tube 17 mm. long, + 1:5 mm. broad, 
at the throat 2 mm. broad; lower lip 11 mm. long, its lobes 5*5 mm. 
long; upper lip 7 mm. long. Upper cell of anther 1:6 mm. long, 
lower (including the slightly eurved spur) 2 mm. Pollen-grains 
usually with 4 rows of tubercles on either side of each pore. Style 
2 cm. long. Capsule 11 mm. long, compressed below. Seeds 
tubercled, brown, rather more than 1 mm. across. 
At first sight this looks rather like Justicia Galeopsis T. And., 
but the narrower leaves and of course the long corolla-tube are easy 
distinguishing features. According to Lindau's views this is an 
Aulojusticia, but I agree with Bentham & Clarke in placing the allies 
of the plant just described in the genus Siphonoglossa.
