HIS somewhat extensive genus is composed of mostly delicate- looking Ferns, the majority of which are of small dimensions and of a brittle nature. In Hooker and Baker's " Synopsis Filicum" Cheilanthes forms Genus 25, which, we are informed, comprises many species extending beyond the Tropics, with fronds tri- or quadripinnatitid (three or four times divided to the midrib) and of a sub-coriaceous (somewhat leathery) texture. The name is derived from cheilos, a lip, and atzthos, a flower ; in reference to the indusium (covering of the spore masses). All the plants included in the genus have their veins free, and a further distinctive character of Cheilanthes resides in the disposition of the sori (spore masses), which are terminal or nearly so on the veins, small, and semi-spherical at first, but becoming more or less confluent afterwards ; their involucre (covering), which is formed from the reflexed margins of the segments, forms roundish and distinct little pouches, as may readily be seen in G. myriophylla and also in C. hirta, or sometimes partly connected together, as in C. argentea, but not quite continuous. Formerly, various Ferns partaking of the above-mentioned characters were considered as representing several distinct genera according to the divisions of their fronds, the smooth or hairy character of their various parts, and the nature of their under-side, which in some plants is perfectly naked and in other cases is thickly covered with a white or yellow, ceraceous (waxy) Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration a
