Foliage comparison of Abies gamblei and Abies pindrow.

[Gaurav Verma]

Here is a Foliage comparison of 2 of 3 native west Himalayan Abies species, i.e. Abies gamblei and Abies pindrow. 
Abies gamblei was used to be considered as a subspecies of Abies pindrow by many authors, i.e. Abies pindrow var. brevifolia but now it has been recognized a totally separate species. The morphological and altitude difference is clearly visible in both. You can see the difference in color and length of needles of both the species in the photo. 

 Abies spectabilis is also present in the same region and is very similar to Abies gamblei. The major difference between Abies gamblei and Abies spectabilis is that Abies spectabilis are more "bicolored" due to the argentea under needles. Both species grow in the same altitude range but A. gamblei prefers drier sites and Abies spectabilis moist. 

All three species hybridize freely in their habitat.

In the photo attached: 

Abies gamblei is from Chitkul Village (3450m), Himachal Pradesh, India. Date of Photo: 8th June 2016. (Starting altitude for gamblei)

Abies pindrow is from Hatu Peak (3400m), Himachal Pradesh, India. Date of Photo: 4th June 2016. (Topmost altitude for pindrow)
