Syst. 43(Beibl. 98): 50. 1909. Urostachys gigas (Herter) Herter, Re-pert. Spec. Nov. Regni Veg. 19:164. 1923. Lectotype (chosen by Herter, 1923: 164). “Südmexiko. Epiphyt auf Bäumen, besonders Eichen, Hänge der Cordille-ren, 2000 m,” J. Harström s.n. (P). Lycopodium pithyoides is close to L. hippurideum but stouter and with larger leaves. Since it grows high in branches it is probably more common than the few collections would suggest.
