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.

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

1. P. Delamerei, §. Moore in Journ. Bot. 1901, 261. An erect 
seabrid herb, drying black. Stem somewhat tetragonous; internodes 
$-3 in. long. ‘Leaves opposite, sessile, linear or linear-oblong, about 
3 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. Bracteoles 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 1} in. long and ACLOSS ; 
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 
and connective about 24 lin. long. Ovary ovoid, glabrous; style 
included,

The only specimen we have seen of this very distinct species is in the British 
ueum. It differs from all the others in having glabrous flowers. 
2. P. procumbens, Jemsl. <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,
