N. Parryi — Par'-ry-i (Parry's), Eaton. 



This very pretty, greenhouse plant, of small dimensions, is one of the 

 most distinct of all the North American species, and belongs to the group 

 of woolly kinds which comprises N. lanuginosa.^ N. Marantce^ and N, 

 Neivherryi. It is found in a natural state near St. Greorge, Utah, growing 

 in dense tufts, in very dry and exposed places among the crevices of 

 rocks, where it has often to endure long-continued drought and a great 

 amount of heat. It has also been frequently met with in Arizona, in the 

 Valley of Colorado, Marengo Pass, San Bernardino County, California, 

 San Diego, &c. The fronds, which are produced from a short rootstock, 

 thickly covered with chaiFy, blackish scales, are borne on slender, dark brown 

 or blackish stalks 4in. to 5in. long and provided with whitish hairs. The 

 leafy portion, about 5in. long and oblong-spear-shaped, is greenish- white 

 above and rusty- white beneath, a colour due to the slender, pointed hairs 

 which completely cover both surfaces, but the lower one more thickly than 

 the upper. Another peculiarity of this little gem is that the pinnas (leaflets) 

 are again pinnate, the pinnules (leafits) being set very close together and 

 scarcely visible through the woolly covering ; when denuded of this they are 

 found to be very small, either roundish or egg-shaped, and notched, the 

 upper ones being less distinct, and the uppermost even confluent with the 

 terminal segment. Although the outer margin is slightly recurved, it is never 

 sufficiently so to cover the very dark-coloured spore masses which are 

 disposed three or four together, forming a ring of about twenty joints. 

 There is also another noticeable feature, and that is, that when the leaflets 

 have fallen from the rachis or the fronds from the stalks, these remain on 

 the rootstock for a year or more before they fall off or decay. — Eaton^

N. Pohliana— Pohl-i-a'-na (Pohl's), Kume. 



A stove species, of small dimensions, native of Brazil. Its spear-shaped 

 fronds, oin. to 4in. long, IJin. broad, and bipinnate (twice divided to the 

 midrib), are borne on tufted, slender stalks 3in. to 4in. long, naked, black, 

 and of a wiry nature. The leaflets, disposed in numerous pairs and spear- 

 shaped, are provided with several stalkless, oblong, notched pinnules (leafits) 

 of a somewhat leathery texture, and having both surfaces, more especially
