80 SOUTH NIGERIAN PLANTS 



obovatis posticis quam ceteri minoribus ; stnminihus paullulum 

 infra fauces insertis antberis oblongis apice incurvo-extenuatis 

 barbatis ; poUuus granis normalibus. 



Oban ; n. 101. 



A handsome plant about 3 feet high. Leaves up to 16 x 9 cm., 

 often about 12 x 6 cm., sometimes markedly narrowed at some 

 distance from the base, i.e., somewhat panduriform, when dry olive- 

 green above and grey below ; petioles 1-2 cm. long, greyish tomentose. 

 Spike when fully grown about 16 cm. long, the axis covered with a 

 grey pubescence. Bracts 22-25 mm. long, usually with several 

 spinulose teeth upon each edge, purple in the li%dng state. Bracteoles 

 13 mm. long. Larger segments of calyx 9"0 X 1*75 mm., smaller 

 segments 8'0 x 1"5 mm. Corolla white, with a purple spot at the 

 base of each posticous lobe ; tube barely 30 mm. long, 1 • 5 mm. broad, 

 widening to 2 mm. near the top ; anticous lobes about 20 x 12 mm., 

 posticous 12 X 8mm. Anthers 2-5 mm. long. 



This also is near C. guineensis Nees, differing from it in habit, in 

 the spine-toothed bracts and the calyx. The acuminate bracts serve 

 to distinguish it on sight from C. Talhotii; but there are other 

 points, including the pollen, in which the two are diverse. 



TALBOTIA S. Moore, Justicisearum gen. nov. 



Calyx 5-partitus, segmentis inter se fere aequalibus. Corollae 

 tubus cylindraceus, faucibus baud dilatatus ; limbus bilabiatus,

 Stamina 4, didynama, corollae faucibus inserta, filamentis ima 

 basi per paria connatis ; antberae staminum anticorum 2-loculares, 

 staminum posticorum 1-loculares, loculis angustis parallelis
