 1885, in Herb. Levinge. 



N.-W. p. : Kwnaun—Jide Hooker on sheet in Herb. Kew, without ticket ; no 

 rhizome. 



DiSTEiB. — Asia : N. Ind- (Him.), Nepal, Winterhottom ; Sikkim and Bhotan 

 4-10,000'; Assam— Khasi Hills 3-6000', very common. Burma. S. India — very general 

 in forests of Madras Presy. Malay Penins. and Isles. China. Japan. Philippines. Poly- 

 nesia. Australia. S. Afr. : Natal, 



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^ 

 Retz., as being due to the fungus Taphrina cornu-cervi, Giesh.
