Discussion
Reports of Psilotum nudum in New Mexico and in west Texas remain unverified. A wide range of chromosome numbers on material outside the flora has been reported for this species: n =ca.46–56, 104, 210. Most counts, however, are based on n =52 (reviewed in P.J. Brownsey and J.D. Lovis 1987). No count is available from North American material.
Psilotum nudum occurs as a minor weed in greenhouses. Many horticultural forms—including one without appendages and with terminal synangia (A.S. Rouffa 1971)—are grown, especially in Japan.
