I do not recollect seeing Trotter’s specimens from Kashmir ; but I assume 
that they are the same as McDonell’s specimens from Chamba, which seem to be 
quite typical aristatum, though there is no rhizome. In his Supplement of 
1892, Colonel Beddome says of Lastrea affinis : — “ A very variable species 
and the caudex is sometimes creeping and sometimes erect but I maintain 
that this is a physical impossibility, and that such a difference of caudex consti- 
tutes a specific difference. 
Aspidium assamicum (sp.), Kuhn in Linnea, XXXVI, 108, from Sikkim and 
Assam (fide Clarke), seems to be very distinct. On specimens of this in Herb. 
Kew is found the abnormal growth mentioned under Pteris quadriaurita y 
Retz., as being due to the fungus Taphrina cornu-cervi , Giesh.
