Cedrus (common English name cedar) is a genus of coniferous trees in the plant family Pinaceae. They are native to the mountains of the western Himalayas and the Mediterranean region, occurring at altitudes of 1,500–3,200 m in the Himalayas and 1,000–2,200 m in the Mediterranean. Using only the above description and what you know about the world, "Cedrus makes up the largest portion of plants in the family Pinaceae." is definitely correct, incorrect, or inconclusive?
