Dr. Foxworthy has collected for me at Xiali, Sarawak, the type localitN- very 
cop,ou. material of this fern. The ultimate divisions of the frond are .sometimes 
entire, sometimes sinuate or broadly crenate; they are at most 14 cm lon<. The 
son are sometimes borne, as hitherto supposed, on free veinlets; but move often 
on an anastomosing vein which incloses a costal areola. Such costal areolae 
without son are not uncommon. Well-developed specimens fruit verv copiously 
3 .s a common number of sporangia in a sorus. The indnsium is not strongly 
inflcxed as ,n 3/r,^o«». The sporangia are flattened, not as round as in Malonl; 
and the annu us, which is irregular, has many more cells. Pnanerosorus and
