'Algum trees' in the Bible

Send to me also cedar trees, fir trees, and algum trees, out of Lebanon. For I know that thy servants know how to cut timber in Lebanon. And, behold, my servants shall be with thy servants,

And also the servants of Huram, and the servants of Solomon, who brought gold from Ophir, brought algum trees and precious stones.

And the king made of the algum trees terraces for the house of LORD, and for the king's house, and harps and psalteries for the singers. And there were none such seen before in the land of Judah.
