. Throughout North India abundant; extending west to Kashmir, and ascending the 
Mts. to 5000 feet alt.—Distrib. South India, Ceylon, Malay Peninsula and Islands, to 
China, Japan, and Australia. 
This plant differs very little, in my eyes, from Z. flexuosum; it has generally smaller 
fronds and pinnz ; but the greater part of the Kew bundle of ZL. microphyllum was filled 
with the present plant, which seems to me abundantly distinct (see diagnosis of Z. micro- 
phyllum above).

Round Bengal, alt. 0—7000 feet, from Nepaul to Bhotan and Chittagong ; very common. 
—Distrib. South India, Ceylon, Malaya to Queensland and Polynesia, Madagascar. 
This fern is common from 2500 feet down to the plain in Bengal, and extends out to 
Sylhet station. At these low levels it is usually small, 2-4 feet high. It is rare in the 
Himalaya in the region of cultivation, alt. 3000-5500 feet, but appears again in the wet 
forest at 6000-7000 feet alt., and is there very large, often 10-18 feet long.—De Vriese, 
in his Monogr. Marattiacee, divides Angiopteris into two sections and 60 species. All 
the Indian material belongs to the second section, which have no adventitious veinlets 
between the regular veins that start from the midribs of the pinnz. All the Indian 
material is very homogeneous, except as to trifling variation in size. The most marked 
var. is one of Griffith’s, which has the barren pinnze strongly serrate sublaciniate; but 
it looks of the nature of a sport.
