5. P. ambigua, Hemsl. A rhizomatous (?) herb throwing up 

 adventitious (?) stems at distant intervals. Stems square, slender, 

 (!-!• 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 -| in. 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 2^ lin. long, iO-nervecl, equally 5-lobed ; lobes broadly deltoid 

 apiculate, hairy on both sides, rather shorter than the tube. Corolla 

 about f 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 P. 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 number' 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. 



G. P. elata, Hemsl. 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 2|— 3 lin. long. 

 Bracteoles 2, linear or almost filiform, shorter than the calyx and close 

 to its base. Calyx hispid with retrorse hairs, campanulate, 2J-3 lin. 

 long, nearly equally 5-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.
