Anthus sp. (Coombes and Ramsay 2001) in vegetation studies of cushion mires in northern Ecuador as a result may perhaps correspond to P. caryonauta in element or full, but confirmation is necessary. Paepalanthus caryonauta is readily distinguished from standard P. YKL-05-099 biological activity pilosus and P. dendroides by the obtuse leaf guidelines, and by the sepals uniformly thickened and persistent in fruit, to kind an ovoid-ellipsoid diaspore. Even in anthesis, the sepals of P. caryonauta are about twice as broad at the base as those of P. pilosus and P. dendroides. Paepalanthus caryonauta also can be recognized by eye on account of subtle variations in aspect and leaf orientation, together with the leaves normally flatter and much more ascending, i.e., lessNancy Hensold / PhytoKeys 64: 17 (2016)Table 1.

Boeke, who collected P. pilosus and an intermediate kind of P. caryonauta in the similar locality (see below), noted that in P. pilosus, the cushions were “easy to separate” and in P. aff. caryonauta, “difficult to separate.” Inside the Cordillera Vilcabamba Dudley reported cushions up to 3 feet in diameter (Dudley 11194). On the other hand in disturbed roadside p amo at Acjanaco, Young and Cano (1994) comment on the paucity of cushion plants, and usually do not recognize P. caryonauta (“P. pilosus”) as a significant cushion plant species. For other differentiating characters, see Table 1. Paepalanthus caryonauta features a more uniform morphology all through its variety than its close relatives. On the other hand, in Colombia and Ecuador the plants have less thickening inside the leaves and flowers, the presence of a short pedicel in PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/20106880 the staminate flowers, and peduncles normally shorter at flowering time, approaching those of P. pilosus in length.
