*'Tradescantia subscaposa, sp. nova. Glabra : foliis omnibus 

 subradicalibus, subsessilibus latissime oblongis, subito 

 acutatis : panicula 10-25 cm. longa, longe pedunculata, 

 oblonga, composita, floribus plurimis condensatis : petalis 

 purpureo-roseis, venosis : staminibus perfectis 6, filamentis 

 glabris ; antheris ellipsoideis, longitudinaliter dehiscentibus, 

 in connectivo subquadrato lateraliter sessilibus : ovario apice 

 glanduloso-piloso. — Species T. Warszewiczianas, Kunth
