Rynchospora sclerioides H. & A. Bot. Beechy, 99. 1832. 



Bynchospora thyrosidea Nees & Meyen, in Kunth, Enum. PI. 

 2:294. 1837. 

 Not uncommon on the slopes of Konahuanui, Oahu, in damp 

 woods. A handsome species. The later name of Nees & Meyen 

 seems to have been commonly used in botanical books. Their 

 name of R. thyrosidea is used in Linnaea, 9: 297, 1834, but with- 

 out description. It is possible that this name has precedence 

 as a label name, but the first description appeared under R. 

 sclerioides.

Scirpus lacustris L. Sp. PI. 48. 1753.

 stagnantibus et fluviatilibus." 



Scirpus maritimus L. Sp. PI. 51. 1753. 



A form of this species, called variety digynus by Hillebrand,

 about Honolulu.

At Waimea, Kauai, a Scirpus was collected in taro ponds, 

 which has not yet been satisfactorily placed. It is probably 

 an introduced plant, allied to Scirpus debilis.
