The dravpings from which the figure in the Botanical Magazine were taken, repre- 

 sent the stigma as bilobed like that of T. geraniifolia. This bilobing, not accurately 

 reproduced in the Botanical Magazine, is still more inaccurately represented in the 

 figure in the Flore des Serres. This species and the following form a transition to the 

 section Thunhergiopsis. 



35. T. geraniifolia, Benth. in Hook. Niger Flora, 475. Stem 

 slender, climbing, pilose. Leaves cordate, palmatifid or palmatipartite, 

 with short, stift' hairs scattered on both surfaces, l| in. long, 1|

 long, pilose. Flowers on peduncles about 1 in. long ; bracteoles ovate- 

 lanceolate, 1 in. long, pilose outside, glabrous within. Calyx truncate. 

 Corolla-tube \^ in. long, glabrous; lobes about \ in. long, deep purple. 

 Anthers spurred above, glabrous, each lobe with a spur at the base.
