 examinations; but can ofter nothing better. 



62, A. (Euaspidium) giyanteum, Bl. ; caudex ? stipites 1-2 

 feet long brown as well as the rachises generally glossy, 

 fronds ample 1-2 or more feet long submembranaceous dark 

 greenish-brown when dry, pinnate with 4-5 pair of pinnae 

 below bipinnate, pinnoe numerous 4-5 pairs 6-12 inches and 

 more long broad-lanceolate deeply pinnatifid, the upper;nost 

 ones gradually smaller and confluent into a pinnatifid apex, 

 superior pinnae generally having the basal segment decurrent 

 upon the rachis, lowest pair of pinnae (and base of the next 

 pair) often very long a foot and more and again more or less 

 pinnated, segments more or less acute or acuminate serrato- 

 dentate or lobato-pinnatifid, veinlets forming oblong areoles 

 near the costse and costules then variously anastomosing in 

 the pinnae and partially in the segments, the veinlets in the 

 segments nearly all free flexuose more or less divaricating 

 and once or twice forked, areoles including free simple or 

 forked fertile veinlets (rarely any^ sterile ones) and generally 

 with a terminal sorus, within the segments the lowest veinlet 

 on the superior side bears a terminal sorus, sori subinarginal, 

 involucres subcordate. — Bl. En. Fit. Jav. j). 159 {and in Herb.
