104 SPECIES OF ABIES DETERMINED BY 



of A. concolor as those of grandis (Lindl.), and cites grandis and 

 lasiocarpa as synonyms, grandis of Douglas being Bertrand's 

 Gordoniana. 



No. 19 (104). Pinus {Abies) grandis, Dougl., Parlatore in part. 

 Abies grandis, Lindl. 

 Abies amabilis, A. Murray. 

 Abies Gordoniana, Carriere. 

 Abies lasiocarpa, Hort. (not Balf. or Hooker). 



Leaves obtuse and emarginate at the apex, without stomata on 

 the upper surface (very rarely with two or three in a small cluster 

 near the apex). Hypoderma consisting of a few scattered cells 

 under the upper epidermis. Resin canals touching the epidermis 

 of the under side of the leaf. 



A very distinct form (No. 393 of Jeffrey), the scale of which 

 is figured by Mr Murray [op. cit, p. 25, fig. 32). Known com- 

 monly in gardens under the names of grandis and lasiocarpa. It 

 is A. Gordoniana of Carriere and Bertrand. This species can be 

 distinguished with the greatest ease from all its allies by the 

 hypoderma of the leaf, as well as by the bracts of the cone. 



No. 20. Abies Lowiana, Murray, Syn. var. Conif., p. 27. 

 Picea Lowiana, Gordon. 

 Pinus (Abies) grandis, Parlatore in part. 

 Picea Parsonsii, Hort. 

 Picea lasiocarpa, Hort. 



Leaves long, narrow, obtuse or emarginate at the apex, with a 

 broad band of stomata on the upper surface, running in the middle 

 line from base to apex. Hypoderma well developed. Resin canals 

 touching the epidermis of the under side. 



Closely related to Abies grandis, but distinct. Sepai'ated by 

 the different development of hypoderma, by the presence of the 

 stomata on the upper side, and, when growing, by the paler, more 

 yellow colour of the young leafy axes. 



Many native and cultivated specimens have been examined. 

 Specimens from Mr Low of Clapton in Kew Herbarium. Two in 

 the Museum, Royal Botanic Garden, one from Jeffrey (without a 

 number), the other from Mr Andrew Murray, collected by Mr 

 William Murray. It is cultivated extensively, and passes under 

 different names, such as Lowii, Lowii glauca, Parsonii, and lasio-
