Collected on the slope of Waiolani, at an elevation of about 

 2000 feet above "Hillebrand's Gulch." It is a small fern, the 

 smallest of this genus on the islands, and can hadly be called 

 a tree fern. Mann says: "I have seen specimens not over a 

 foot high including caudex and all, in luxuriant vegetation."

YITTABIA Sm. Mem. Acad. Turin. 5:413, pi. 9. 1793. 



Yittaria elongata Swartz. Syn. Fil. 109. 1806. 



Growing on trees, usually on the Kukui, at medium eleva- 

 tions, and common on both Oahu and Kauai (2054). On Kauai, 

 on the ridge above Gay & Robinson's house, occurred the form 

 known as V. zosteraefolia (2532), which has the lower side of the 

 groove shorter, thus plainly showing the fructification.
