 hirtipes, not the short ovate ones of Scottii (type).

 wide-creeping ; stipes 12-18 inches long, slender, stramineous, 

 naked, glossy ; fronds 8-12 inches long, nearly as broad, deltoid ; 

 lower pinnae 4-6 inches long, the lowest pair deflexed, often 

 2 inches broad ; the pinnules reaching down nearly to the rachis, 

 those of the lower side 1-1^ inches long, pinnatifid half-way down, 

 with broad blunt lobes ; texture thinly herbaceous, under side 

 slightly villose ; veinlets pinnate in the lobes ; sori marginal.
