In differentiating this species, Standley (Field Mus. Publ. Bot. 8: 69. 1930) remarks that it is distinguished from P. amita Standi, by the form of the stipules, by the leaf pubescence, and by the larger corolla. Other differences are noteworthy as follows: in P. eggersii the flowers are tetramerous with conspicuously corniculate-tipped corolla lobes, whereas in P. amita the flowers are pentamerous and the corolla lobes are not corniculate; in P. eggersii the corolla tube is more slender and has a puberulous tomentum on the exterior with short spreading hairs, whereas in P. amita the relatively broader and shorter corolla has a close papillate puberulence without. Finally, in P. eggersii the calyx lobes are conspicuously developed with ovate, acute to acuminate lobes which surpass the disk, whereas in P. amita the calyx is shallowly cut and the disk merely equals or exceeds the height of the calyx lobes.
