o P. ambigua, Hemsil. A rhizomatous (?) herb throwing up 
adventitious (?) stems at distant intervals. Stems square, slender, 
6-9 in. high, with a few opposite branches, hispid, with short, retrorse 
bristles, Leaves all opposite, linear-lanceolate, the largest scarcely 1 in. 
long, mostly much smaller, shorter than the internodes, acute, narrowed 
downwards, rather thick, densely clothed with short, tubercled bristles, 
entire; veins obsolete. Flowers solitary in the axils of the leaves, 
about din. long. Pedicels slender, lower ones shorter than the floral- 
leaves or bracts, the upper longer. Bracteoles subulate, close under the 
calyx, scarcely a line long. Calyx hispid, campanulate, rubescent, 
about 21 lin. long, i0-nerved, equally 5-lobed ; lobes broadly deltoid 
apiculate, hairy on both sides, rather shorter than the tube. Corolla 
about ? in. across, hairy outside, inflated from the base; limb nearly 
equally 5-lobed ; lobes rounded, slightly hairy inside near the tips. 
Anthers longer (¢) than the filaments.

We at first took this to be 2. Hildebrandtii, Engler, and it may be an abnormal 
condition of that species, of which we have seen no specimen with roots. P. ambigua 
has an underground stem or rhizome, from which rise a vumber of short, erect 
stems from adventitious buds. It is much less branched; has larger leaves, 
slenderer pedicels and a rubescent calyx with apiculate lobes. 
Possibly the only specimen we have is of abnormal growth. 
6. P. elata, Hemsi. An erect hispid herb or shrub. Stems few, 
erect, rigid, simple or with few erect branches 2—3 ft. high, 4-angled, 
rough with retrorse bristles. Leaves all opposite or nearly so, distinctly 
petiolate, rather thin, but rough with tuberculate hairs, linear-lanceolate 
or linear-oblong, 1-1? in. long, smaller upwards, obtuse with an apiculate 
tip or the upper ones acutely acuminate. Flowers solitary in the axils 
of the leaves and bracts, 7—9 lin. long. Pedicels 23-3 lin. long. 
Bracteoles 2, linear or almost filiform, shorter than the calyx and close 
to its base. Calyx hispid with retrorse hairs, campanulate, 24-3 lin. 
long, nearly equally -lobed; lobes broadly ovate, somewhat acute, the 
two lower a little larger than the others and apparently recurved, 
Corolla (a perfect one not seen) 7-8 lin. long, very hairy outside, 
glabrous within, distinctly veined, cylindrical at the base then suddenly 
inflated ; limb oblique, nearly equally 5-lobed ; lobes rounded. Stamens 
included, glabrous, very similar to those of P. obtusifolia. Ovary and 
lower part of slender style, pubescent. Ovules numerous.
