nately placed on each side of the rachis. The 
branches are lance-shaped, having on each side, 
over and under the stem, a row of leaflets, largest 
next the rachis, and becoming shorter towards the 
point of the branch. These leaflets are narrow 
and blunt pointed, each one somewhat deeply 
notched or toothed, being in this way divided into 
segments, which are finely saw-edged. 
The Rigid Buckler Fern is a very elegant plant, 
and like the other Lastreas admirably adapted for 
cultivation. In the sandy peat, loam, and leaf- 
mould used for growing this beautiful Fern, some 
pieces of limestone should be placed; and it must 
have an abundance of moisture.
