A large genus of ornamental Ferns with gracefully cut fronds. The spore clusters are roundish, and situate near the ends of the free veins. The only species of market value is G. elegans, the Lace Fern, and even this is rarely seen. It is a form of the Tropical American C. myriophylla, and has fronds 10-20 in. long, thrice-pinnately cut into small pouch-shaped pinnules - smooth above, hairy beneath. It grows freely in a warm greenhouse, and sells best in small pots.
