This is a Mexican tree Fern 10-15 ft. high when full grown. It is an excellent Fern, and sells by the thousand in America. It has not yet "caught on" with British growers, but its elegant character is sure to force itself upon them in time. As a room Fern it is very valuable, as I have known it to stand in a dining-room, heated by gas throughout the winter, without suffering any ill effects. The oblong deltoid fronds are thrice pinnate with oblong lance-shaped pinnae and linear lance-shaped pinnules. The spore clusters are near the margins at the end of the veins.
