Discussion:

A. poarchon var. exaltata Malme, nomen.

A. chapadensis Hoehne, Comm. Link. Telegr. Estrat. Matto Grosso, Annexo 5, Bot. pt. 5: 11. pl. 80, f. 2. 1915.

A. poarchon is a variable species, undoubtedly having within it a number of segregate populations of greater or lesser distinctness. It is most closely related to A. pidchella, and indeed merges with this species. Because of its larger habit, more numerous flowers, and acute mucronate cephalar bracts, it is in most in stances easily separable from A. pulchella, of smaller habit with few-flowered (usually 2-3) spikes, and obtuse, umbose, short linear appendiculate cephalar bracts. By the use of these criteria, there are included in the exsiceatae cited below a number of plants which because of their shorter narrower leaves have been interpreted as belonging to A. pulchella.
