Gleichenia semivestita. Half-clothed Gleichenia. Re- 
sembling microphylla, of which it is probably a variety. 
Its distinguishing feature is the greater hairiness of the 
stems. It attains a height of about 3 feet. 
Gleichenia speluncce. Cave Gleichenia . Very glaucous 
in colour, and white beneath, perhaps the most beautiful 
of the family. It grows in caves and dells ; it and its 
brethren are natives of Australia. 
Pteris arguta. Sharp-notched Brake . Caudex creep- 
ing ; fronds spreading, many times divided, triangular in 
form and of a pale green colour ; leaflets bluntly oblong 
and sharply serrated ; stems rich brown, a foot long, the 
leafy part of the frond measuring two feet. This noble fern 
requires a great deal of room ; it is a native of Madeira. 
Pteris Cretica . Cretan Brake . Fronds pinnate, up- 
wards of a foot high, of a beautiful vivid green ; fertile 
fronds with long narrow pinnae, those of the barren 
fronds long, lance-shaped, the lowest pair sometimes 
forked ; stems pale. Found in Crete, China, the East 
and West Indies, and Southern Europe. 
Pteris Kingiana . Captain King’s Brake . Fronds bi- 
pinnate in the lower part, spreading, 2 feet high ; pinnae 
long, lance-shaped, sharply serrated, drooping. A Norfolk 
Island species. 
Pteris scaherula. Roughish Brake . Fronds divided 
into very fine segments, triangular in form, spreading 
horizontally; and of a beautiful light green colour, 8 or 9 
inches high. A perfect little gem, and should be grown 
near the glass in a greenhouse, and never exposed to cut- 
ting draughts. A native of New Zealand. 
Pteris serrulata . Finely -serrulated Brake . A small 
flaccid variety of our wild Brake, with minute leaflets 
and arching stems.
