This is the first Rolhnidia which has been reported off the island of Oahu. It

 of Kauai.

The plant in question is certainly wortliy of specific rank. Young plants 

 which the writer observed were of the same habit as mature ones, both having

 leaves when younu' and also when in a mature state, h'. aiit/ugtifolia difl'ers
