Mschynanthus, Jack, was published Jan., 1823; but Trichosporum, D. Don, 

 being published July, 1822, has the right of priority ; Mschynanthus, however, 

 having been accepted for half a century, it would not be expedient to relinquish it. 



Sect. 1. Politrichium. Seeds^th. many hairs near the hilum, and 

 one hair at the apex.
