"So. 36.i is one of the curioua intermediates often found in Lygodium, tlie 
segments or pinnules being partly fertile. The change is rather abrupt, the 
fertile part promptly losing all the lamina. These pinnules have the plan of 
ordinary sterile ones,

King sends this as the "inland variety" of L. scandens, but says "L. scandens 
along side this, and the contrast is marked." The two species are very distinct, 
L. scandens having naked axes, the dwarf branch slender and 3 mm more or less 
in length, the tliickening of the head of the pedicel evident after, but not before, 
the fall of the pinnule, and the spores white, and reticulate, rather than tuber- 
culate in appearance. My specimen, ticketed "L. microphyllum Sw.", collected 
by Hahn at Yabim, German New Guinea, is a mixture of sterile L. scandens and 
fertile L, flexuosum.

A sterile specimen collected at ilamba may be a hybrid of L. japonicum and 
L. circinnatum, but might be a monstrous L. dimorphum, the sterile pinna taking 
the plan of the fertile.

Christ does not mention the auricled bases of the segments, which are con- 
spicuous though small on all of King's specimens, but the plants are otherwise 
alike. One of King's specimens. No. 360, is entirely sterile, and the segments 
are 40 cm long. The stalk of the pinna is suppressed; that of the segments is 
up to 1 cm long, and usually provided with separate auricles.

The fertile frond of No. 361 has the veins free, while that of B. .}6 has a row
