stalk, is rather oblique; their entire under surface is 
densely clothed with brown, pointed, imbricated scales, 
which, when earinied yates the seston are found 
veins are few in number, alternate and irregularly 
branched, the branches occasionally uniting with each 
x before their termination: the anterior branch of — 
h bears an elongate mass of seeds; these are 
ted about midway between the midrib and the 
“margin of the pinna; the first anterior lateral vein 
ally bears two masses of seeds, one on each side of 
principal branches; the seeds are attached to that 
e of the vein which is nearest to the middle of the 
_ pinna, and not on the back of the vein; it should, 
however, be observed that the seeds seated on the 
veins nearest the midrib of the frond are placed in a 
akko ilies towards the stem. Immediately adjoining 
the attachment of the seeds, and also attached to 1 
back of the vein, is an erect, white, very narrow, mem- 
--branous involucre, exactly corresponding in length with © 
line of seeds with which it is connected. This 
8 a microscopic object, and is merely mentioned for the 
ke of precision; it can only be detected by one who 
expert in making such investigations.
