In all probability Riccardia prehensilis is confined to the moist 

 regions of southern South America. At one time it was supposed 

 to occur also in New Zealand, but the old determinations upon 

 which this opinion was based have since been proved incorrect. 

 Later on Stephani reported its occurrence in Java (27, p. 664), 

 basing his statement apparently on old specimens in the Mitten 

 Herbarium. These specimens are labeled "Java" and clearly 

 represent R. preJiensilis, but it is doubtful if they really came from 

 Java. At any rate Schiffner makes no mention of such a plant in 

 his careful work on the Javan species of Riccardia^ and neither 

 R. prehensilis nor any closely allied species has lately been found on 

 the island.
