MedChemExpress CCT196969 caryonauta in portion or full, but confirmation is required. Paepalanthus caryonauta is readily distinguished from common P. pilosus and P. dendroides by the obtuse leaf recommendations, and by the sepals uniformly thickened and persistent in fruit, to form 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 as a result of subtle variations in aspect and leaf orientation, together with the leaves typically flatter and more ascending, i.e., lessNancy Hensold / PhytoKeys 64: 17 (2016)Table 1.

Boeke, who collected P. pilosus and an intermediate type of P. caryonauta at the similar locality (see under), noted that in P. pilosus, the cushions had been “easy to separate” and in P. aff. caryonauta, “difficult to separate.” Inside the Cordillera Vilcabamba Dudley reported cushions as much as 3 feet in diameter (Dudley 11194). Having said that in disturbed roadside p amo at Acjanaco, Young and Cano (1994) comment around the paucity of cushion plants, and usually do not recognize P. caryonauta (“P. pilosus”) as a considerable cushion plant species. For other differentiating characters, see Table 1. Paepalanthus caryonauta includes a additional uniform morphology throughout its range than its close relatives. Even so, in Colombia and Ecuador the plants have less thickening within 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 typically shorter at flowering time, approaching these of P. pilosus in length. Hybridization. Paepalanthus caryonauta and P. pilosus are largely allopatric, but in Colombia you can find points of contact where intermediates occur.
