didynamous, included, dimorphic, all inserted nearly on the same level ; 

 upper pair smaller without any appendage ; lower pair having a 

 2- branched connective; upper branch bearing a large anther-cell; 

 lower branch shorter, curved upwards and terminating in a disk- 

 shaped appendage ; anthers all 1-celled and dehiscing by a terminal 

 pore. Ovary 2-celled, many-ovuled. Capsule ovoid, 2-valved. Seeds 

 numerous, rather large, angular, oblique, deeply pitted. 

 Species 7, endemic. 



The genus is easily distinguished from all others by the peculiar structure of the 

 stamens.

1. P. Delamerei, S. Moore in Journ. Boi. 1901, 261. _ An erect 

 scabrid herb, drying black. Stem somewhat tetragonous ; internocles 

 £-f in. long. Leaves opposite, sessile, linear or linear-oblong, about 

 X in. long, obtuse. Bracts similar to the leaves but smaller. Flowers 

 solitary in the axils of the leaves or bracts, rather large for the genus. 

 Pedicels 2-3 lin. long. JBracteoles 2, opposite, about 1| lin. long, 

 not close to the calyx as in most species. Calyx broadly campanulate, 

 about 5 lin. long, obscurely nerved, glabrous ; lobes triangular, acute, 

 shorter than the tube. Corolla glabrous, nearly 1J in. long and across ; 

 tube cylindrical at the base and suddenly inflated ; limb 2-lipped ; 

 upper lip emarginate, lower shortly 3-lobed ; lobes all rounded and 

 undulated. Stamens included. Anther-cells oblong, tapering up- 

 wards, dehiscing by a terminal pore ; abortive cell of the lower pair 

 ancl connective about 2-|- lin. long. Ovary ovoid, glabrous; style 

 included. 



Uile Land. British East Africa : Dadaro, 3700 ft., Lord Delamere ! 

 The only specimen we have seen of this very distinct species is in the Britisk 

 Museum. It differs from all the others in having glabrous flowers. 



2. P. procumbens, Hemsl. A trailing, hispid, perennial herb 

 with numerous very slender stems, 3-8 in. long ; internodes mostly 

 rather longer than the leaves, especially upwards. Leaves all opposite, 

 rigid, hispid, sessile, the lower quite small almost scale -like, larger 

 upwards, oblong, lanceolate-oblong or ovate-oblong, 3-5 lin. long,
