Choice Ferns for Amateurs. 
ADIANTVM— continued, 
A, roseum. 
A green^liouse Fern, of dwarf Juabit, whose fronds, 
scarcely 5in. long, are of a lovely pinkish tint when young. 
It' is of garden origx^. 
A. rubellum. 
This very pretty, stove species, closely allied to and 
intermediate between A. Wagneri {A. decorum of com- 
merce) and A. tinctum, is a native of the Andes of Bolivia : 
it is of dwarf but elegant habit. The fronds, which are 
abundantly produced from a close, tufted crown, and borne 
on exceedingly slender, black, shining stall^s, 4in. to 6in. 
long, have their leafy portion of similar length; they are 
deltoid and bipinnate. The numerous leafits are fan- 
shaped at their summit, wedge-shaped at their base, and 
their outer margin is lobed and finely toothed : they are 
almost stalkless, and when young are of a beautiful 
purplish-crimson, changing with age to a light bluish-green 
tint, but even then tinged with pink. The sori are round 
or slightly kidney-shaped, and are disposed singly in th<-) 
tips of the lobes. 
A. scutum. 
A popular name for A. Ghieshreghtii. 
A. Seemannii. 
This very handsome and totally distinct, stove species, 
also known under the names of A. populifolium and A. 
Zalinii, is a native of Guatemala and Brazil. It is of very 
peculiar growth, inasmuch as while in a young state the 
plant only produces simple fronds of extraordinary dimen- 
sions, which are then heart-shaped, with an elongated point, 
and often measure as much a© Sin. in breadth: they are 
produced from a thick, underground rhizome, and are borne 
on upright, black, shining stalks 6in. to 9in. long. With 
maturity the fronds become pinnate, the lower pair of 
pinnae being occasionally divided again. The pinnae, which 
are larger than even those of the popular A. macropJiyllum, 
and have black, polished footstalks often lin. long, are 
then ovate, acuminate, unequal-sided, and drooping at right 
angles from the stalk. The barren pinnae are usually finely 
dented, while the fertile ones show on their outer margin 
an uninterrupted line of oblong sori. The foliage, of a par- 
ticuliarly leathery texture, is, when only partly developed, 
of a bronzy or metallic hue, turning with age to a deep glossy- 
green above, and a pretty bluish colour beneath. 
A. sessilifolium. 
This is synonymous with A. Henslovianum.
