Hybrids are known to occur in nature, but they are generally between closely related species and give rise to fertile offspring which often make the taxonomy of the group difficult. Natural hybrids that give rise to sterile forms are not so common. The purpose of this paper is to put on record two such hybrids observed in Alaska.
