772 MINNESOTA BOTANICAL STUDIES. 



Growing on trees at altitudes of about 3500 to 4000 feet, above 

 Waimea, on the ridge west of the Hanapepe river, and near the 

 head of the Wahiawa, Kauai. 



This finely marked species belongs to the § Elapkoglossum, 

 but has the texture of A. reticulatum. According to Mr. Heller, 

 it "grows on upright trees, from ten to twenty feet from the 

 ground, and grows around the trees. The thick, hairy root- 

 stocks seem to be an accumulating place for dirt and eventually 

 a disk is formed completely around the tree, usually extending 

 out at least six inches from it. * * * It does not occur 

 below 3000 feet and is most plentiful at about 3500 feet."
