Ursulan

From Tardis Wiki, the free Doctor Who reference

Ursulans were inhabitants of Ursu representing eight different species. They were created from Blooms placed on the planet by the Ursu Group and due to this could not reproduce. Male Ursulans could however reproduce with other species. (PROSE: Beyond the Sun)

Behind the scenes

Matt Jones named Ursulans after Ursula K. Le Guin. (REF: The Big Finish Companion: Volume 1)
