 133 bis (hb. Gr.). Widely distrib. in trop. Am. Now one of the most 

 abundant and generally distributed plants of the islands, but apparently of 

 recent introduction, as it was not noted by Darwin or any of the earlier 

 collectors. Andersson in 1852 found it upon two islands, Baur in 1891 

 upon five, and Snodgrass & Heller in 1899 upon seven.
