ACANTHACE-^ (S. Moore) 85 



exsertis antherarum loculis linearibus loc. inf. solum calcarato ; 

 stylo apice 2-dentato puberulo ; capsnla anguste obovoidea acuta 

 superne puberula alibi glabra 4-sperma. 



North Nigeria, R. Benue. 



Leaves 3-5 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 lum. 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 l"6mm. long, 

 lower (including the slightly curved 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 Sij)honoglossa.
