The books are magnificent. The brief species desciptions with a focus on diagnostic characters are very informative and the excellent photos are a treat!
As discussed in Conifers Around the World (see pages 1013 to 1015, as well as the species descriptions on p. 300 and 306) the two plants are different enough not to confuse them. It is also clear today that the plant described as Abies pindrow var. brevifolia (by Dallimore and Jackson in 1923), and recently treated as Abies pindrow subsp. gamblei by Rushforth (1999) cannot be placed under Abies pindrow – it is a different entity.
Though Abies spectabilis may occur at such altitudes (exemplified by a few trees in the upper Langtang Valley in Nepal) those places belong to the wetter parts of the Himalayas. Abies gamblei however grows in the drier parts of the Himalayas, from western Nepal westward to eastern Afghanistan. In this rather extensive area, it separates from Abies pindrow at altitudes around 3000 m, with the latter always at lower elevations while Abies gamblei appearing around 3000 m and reaching 3500 m.There are no transitional forms between the two. Their morphological differences are rather obvious, as shown in the species plates here.
