Discussion
Urostachys reflexus (Lamarck) Herter, Beih. Bot. Centralbl. 39: 249. 1922. Huperzia reflexa (Lamarck) Trevisan, Atti Soc. Ital. Sci. Nat. 17:248.1874 [1875]. Type. Martinique. Martin s.n. (P-Lam. 442). Lycopodium reflexum is common on moist banks in Oaxaca and distinct by its erect, dichotomously forking stems with spreading leaves and conspicuous sporangia. There are many splinter names for slight variations in Costa Rica and South America, but Oaxacan material is uniform and compares favorably with the West Indian material of the type variety. It is reported by A. R. Smith (1981) to be rarely epiphytic, but not otherwise reported as such for this abundant species; further observations are needed.
