100 SPECIES OF ABIES DETERMINED BY 



burgh, have also been examined. The cones of A. balsamea and 

 A. Fraseri are sufficiently distinct. 



(96.) Pinus (Abies) Jirma, Parlatore (not Antoine). 



Parlatore gives Abies bifida and Abies homolepis as synonyms of 

 his P. Jirma. In this I cannot concur. 



Xo. 11. Abies Jirma, Sieb. and Zucc. (not Parlatore). 



Leaves slightly wider near the apex than above the base, apex 

 rounded and emarginate. A few stomata occasionally in a patch 

 on the upper surface near the apex, below with a band on each 

 side of the midrib. Hypoderma well developed. Resin canals in 

 the parenchyma of the leaf. 



Only two specimens of Jirma have come under my notice, both 

 of them in Kew Herbarium, and named Jirr/ia, Sieb. and Zucc. One 

 was sent from Nagaski, Japan, by Oldham, in 1862 ; the other was 

 collected in Japan, Nippon, by Maximiowicz in 1864. It is not 

 in cultivation, all the plants I have seen under this name being A. 

 bifida. Abies homolepis, Sieb. and Zucc, sunk by Parlatore as a 

 synonym of Jirma, I have not seen ; but, according to Bertrand, 

 it only differs from A. Jirma in having fewer stomata on the under 

 surface of the leaf, a character of no importance. Abies brachy- 

 phylla, Maximiowicz, Pinus brachyphylla, Parlatore (No. 98), is 

 anatomically the same as Abies Jirma. 



No. 12. Abies bifida, Sieb. and Zucc. 



Leaves tapering towards the bifid apex ; no stomata on the 

 upper surface, below with a band on each side of the midrib. 

 Hypoderma well developed. Resin canals close to the epidermis 

 of the lower side of the leaf. Parenchyma of the mesophyll of the 

 leaf with numerous scattered, elongated, unbranched, greatly thick- 

 ened, liber-like cells (idioblasts), quite peculiar to this species. 



I have received the plant under the name of bifida from the 

 Royal Botanic Garden, Edinburgh, and have compared it with an 

 authentic specimen in Kew Herbarium. A narrower leaved form 

 of the same species is also cultivated (without a name) in the Edin- 

 burgh Garden. It is the form cultivated as Abies Jirma, and has 

 been sent to me under this name from Messrs Veitch of Chelsea, 

 and from Castle Kennedy. Mr Fowler sent me a " late variety," 

 in one of the leaves of which there was a slight abnormality, the 

 resin canal of one side being slightly distant from the epidermis.
