80 SOUTH NIGERIAN PLANTS 
obovatis posticis quam ceteri minoribus; staminibus paullulum 
infra fauces insertis antheris oblongis apice incurvo-extenuatis 
barbatis ; pollinis granis normalibus. 
Oban ; n. 101. 
A handsome plant about 3 feet high. Leaves up to 16 x 9 cm., 
often about 12 x 6 em., 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 living 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 80 mm. long, 1:5 mm. broad, 
widening to 2 mm. near the top; antieous lobes about 20 x 19 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. Talbotii; but there are other 
points, including the pollen, in which the two are diverse. 
TALBOTIA S. Moore, Justiciearum gen. nov. 
Calyx 5-partitus, segmentis inter se fere aequalibus. Corollae 
tubus cylindraceus, faucibus haud dilatatus; limbus bilabiatus, 
labio postico erecto bidentato antico aestivatione exteriore 3-lobo. 
Stamina 4, didynama, corollae faucibus inserta, filamentis ima 
basi per paria connatis ; antherae staminum anticorum 2-loculares, 
staminum posticorum  l-loculares, loculis angustis parallelis 
muticis, staminum anticorum altero altero altius affixo. Pollinis 
grana pileiformia spinis brevibus copiose obsita verisimiliter facie 
interiori fissura lineari praedita. Discus cupularis. Stylus 
filiformis; stigma bilamellatum. Ovula quove in loculo 2. 
Herba humilis, caule radicante. Folia comparate lata, inte- 
gerrima. Flores inter minores, in spicas strobiliformes axillares 
vel pseudoterminales late bracteatas digesti. Bracteolae calycem 
multo excedentes. 
Talbotia radieans S. Moore sp. unica. Herba caule gracili
