H. (Lastrea) vestitum— Las'-tre-a ; ves-ti'-tum (clothed), Baker. 



This stove species, also known in gardens as N. Raddianum, 

 is a native of Brazil. It has a very striking appearance, produced by the 

 long, woolly, cinnamon-coloured scales which densely cover its stalks on 

 their entire length. These stalks are 6in. to 12in. long and bear very 

 decorative fronds 1ft. to 2ft. long and 6in. to lOin. broad. The leaflets, Sin. 

 to 5in. long and about lin. broad, are cut down to a narrowly -winged midrib 

 into blunt, sickle-shaped lobes of a soft, papery texture and bright green 

 colour. The sori (spore masses) are situated close to the midrib. — Hooker^

N. (Lastrea) Yillosum— Las'-tre-a ; vil-lo'-sum (hairy), Presl, 



This evergreen, stove species, which is said sometimes to attain a height 

 of 18ft., is a noble species when well grown. It is a native of the West 

 Indies, Jamaica, and the Caribbean Islands, and, according to Lowe, was 

 introduced into the Royal Gardens, Kew, in 1844, by Mr. N. Wil son. Its 

 gigantic fronds are borne on stout stalks 2ft. to 3ft. long, usually hairy, and 

 clothed with spreading scales ; they are produced from an arborescent trunk, 

 and their stalks and rachises (stalks of the leafy portion) are completely 

 covered with narrow, fringed scales. The leaflets, often 2ft. long and 1ft. 

 broad, are divided into spear-shaped pinnules (leafits) cut down to the rachis 

 into close, oblong, deeply-cleft segments of a soft, papery texture and pale 

 green colour. The abundant sori (spore masses), disposed half-way between 

 the midvein and the edge, are covered with a flat involucre, which is as 

 often suppressed as developed. — Hooker, Species Filicum, iv., p. 134, t. 264.
