N Hooker and Baker's " Synopsis Filicum" Lonchitis forms Grenus 23. Mettenius unites it with Pteris, from which it differs only by the position of the sori (spore masses). The name is derived from lonche, a lance, in allusion to the shape of the fronds. The distinguishing characters reside in the disposition of the sori, which are marginal and placed in the sinuses (depressions) of the fronds, and in the shape of these organs, which usually are more or less reniform (kidney-shaped), but sometimes considerably elongated. The involucres, of the same shape as the sori, which they cover, are of a parchment-like texture, and are formed of the reflexed margin of the fronds on which the spores are produced. So far as we know, the geographical distribution of the genus Lonchitis is limited to Africa and the adjacent islands, Mauritius, Bourbon, Madagascar, &c., though it is reported by Linden that he collected L. Lindeniana (L. imhescens) in Caracas, South America. Only a couple of species of this genus are known at present: both of these are bold-growing plants, provided with underground rhizomes (prostrate stems) of a fleshy nature. Their crowns, which sometimes grow a few inches above the surface of the soil, are also very succulent, and produce robust fronds, borne on light-coloured stalks, which, when young, are of a semi- transparent 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 may not perfectly resemble the original Schneider, George.
