An Enumeration of Niihau Plants. 25 



MYOPORACEAE. 

 Myoporum sandwicense (A. DC.) A. Gray. 



RUBIACEAE. 

 Morinda citrifolia L. 



LOBELIOIDEAE. 

 Brighamia insignis A. Gray. 



Mr. Stokes observed on inaccessible cliffs. The plant is known 

 from Kauai, Molokai and L,anai, but not as yet from the other islands. 



Delissea undulata Gaud. 



Brigham in herbarium of Bishop Museum; not seen by Mr. 

 Stokes. Dr. Brigham says that this is the only lobelia that he saw 

 on the island, and that it was more plentiful over the area where 

 it occurred than perhaps any other lobeliaceous plant occurring in 

 an equal area on the group. 



I,obelia neriifolia Gray, var. 



Field experience is showing this to be a variable species; the 

 present specimen collected by Mr. Stokes may prove to be a dis- 

 tinct variety. 



GOODENIACEAE. 



Scaevola Koenigii Vahl. 

 Scaevola coriacea Nutt. 



Collected by Remy ; not seen by Stokes.

Ageratum conysoides L.
