The Davallias are graceful Ferns with creeping hairy rhizomes, bearing some fancied resemblance to a hare's foot. The spore clusters are marginal and the veins free. Of the large number of species comparatively few find a place with the market grower. Amongst the best may be mentioned D. bullata and its varieties decora and Mariesi, the latter being very popular for the extraordinary shapes into which it is made by the Japanese - frogs, toads, monkeys, balls, etc. D. canariensis, D. dissecta, D. tenuifolia, D. stricta, D. Tyermanni, D. Speluncoe, D. Griffthiana, and others are sometimes brought to market chiefly in baskets. They are all graceful in appearance, but may be grown as easily in pots as in baskets.
