GLEICHENIA SPLENDIDA Hand-Mzt. Akad. Anz. Akad. Wien (1924) 81; Symb. Sin. 6: 16 
(r929); C. Chr. Ind. Fil. Suppl. TIT. 106 (1934). 
Gleichenia linearis C. Chr. (non Clarke, 1880), Contr. U. S. Nat. Herb. 26: 271 (1931), pro parte. 
Rhizome wide-creeping, dull brown, subnitid, muricate, densely scaly; scales atro- 
brown, linear-subulate, rigid, spreading, tufted, deciduous; frond i to several meters tall, 
erect or trailing, stipe dark straminous, shining, glabrous, 4-5 mm across, 30 cm to several 
meters long, lamina repeatedly di- or trichotomously forked, with a distinct pair of pinne 
arising from the base of the primary forking branches and two smaller foliaceous and 
coriaceous ones at the axil covering the scaly terminal bud; pinnae 30-40 cm long, 10-16 
cm broad at the middle, gradually acuminate towards apex, base decrescent either on both 
sides or the upper side only, sessile, pectinately pinnatifid, segments 5-10 cm long, up to I 
cm broad above the broadened base, linear-lanceolate, with obtusish apex, and repando- 
undulate margin; texture subcoriaceous, glaucescent beneath; veinlets 5-6 in each group, 
parallel; sori irregeularly 1-2-rowed, medial on veinlets, consisting of 10-20 sporangia.

A gigantic species of the group of G. linearis (Burm.) Clarke and has previously 
been considered as identical with that common fern, from which it differs in enormously 
larger size in all parts, the segments being up to 10 cm long and nearly r cm broad, with 
repando-undulate margin, and more sporangia in each sorus, which is, however, rarely 
found present.
