Nephrolepis robusta, Craig, 1912, from elegantissima. Lvs. 2-2¼ ft. long, 10-12 in. wide, erect, firm, 1-2-pinnate, the pinnae 4-6 in. long, 1½-2 in. broad when 2-pinnate, lobed at the base, narrower when not divided, the pinnulae; full, entire or crenulate. For the first year or so after its intro. this form showed little reversion but more recently it has begun to throw 1-pinnate lvs. It is a larger more open form than elegantissima and consequently more hardy. From Piersonii it differs in being broader-lvd. and more erect.
