Premise: Abies spectabilis (East Himalayan fir) is a conifer species in the family Pinaceae and the genus firs. It is sometimes held to include the Bhutan fir ("A. densa") as a variety. It is found in Afghanistan, China (Tibet), northern India, Nepal, and Pakistan. It is a large tree, up to 50 m tall.
Hypothesis: The tree doesn't go up to 50 m tall and isn't found in Afghanistan.  Instead it is found in different climates.
