OMPOSED of tropical species of arborescent liabit resembling Cyatheas, this genus forms as it Avere a connecting link between those plants and the Alsophilas, and the species are often difficult to recognise—a circumstance that accounts for the popular error respecting H. capensis, which is usually called Alsopkila capensis. The name Hemitelia is derived from hemi, half, and telia, a lid, in reference to the shape of the indusium (covering) of the sori (spore masses), which is in the form of a scale, situated on their under-side, varying in size, shape, and texture, and often deciduous. The sori themselves, invariably situated upon a vein or veinlet, are roundish, and, when seen through a magnifying lens, appear to resemble mulberry fruits in miniature. Hemitelia represents an important section of the tribe Cyathece., and in Hooker and Baker's " Synopsis Filicum" forms Genus 5. Although not numerous, the species are widely scattered over tropical countries, four or five being native of South America, the same quantity being indigenous to India, Ceylon, and the Pacific Islands, while others are of West Indian or of New Zealand origin. The plants are all furnished with ample fronds, simply pinnate (only once divided to the midrib) or decompound (many times divided) ; their veins are simple or branched, free or, those on the ribs especially, more or less intercrossing. To those with all the veins free T. Moore gave the name Amphicosmia, which has not been Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations m
