veinlets after entering the lobe ; (7) and finally, the fructification is different : 
there is no rigid, straight-backed aorus in A. McDonelli % but, on the contrary* 
the utmost possible liberty and variety of shape. There is generally one soras 
to each lobe, on the superior veinlet ; but in the lowest lobe there are sometimes 
two, and then the fewer is attached to the lower side of the inferior veinlet, and 
the upper to the upper side of the anterior veinlet, so that they are placed back 
to back, bub separated by the space between the two veinlets. All shapes of 
involucre may be found on the same pinnule : shorb-asplemoid,’ athyrioid, pear- 
shaped— spreading on both sides of a veinlet without any apparent sinus or 
back at either end, and shorb-diplazoid— as described above under A. thdypte- 
roides. Beddome, I think, at first intended to describe A. McDmelli as a 
Diplazium, and he says it has the habit of the Ceylonese D. Schliurii , and the 
Cuban D. conchatum. It has almost as much right to a place under Diplazium 
as A.japonicum has. The description requires revision by the light of the 
new material from Kashmir. A. Emryi , Baker, from China, is doubtfully 
distinct.
