Lactra VII was the inhabited seventh planet of the Lactra planetary system. This M class planet with Earth-normal atmosphere and gravitywas the homeworld for the Lactrans, a highly advanced non-humanoid telepathic species. The planet was located several light years away from Canopus III in the Alpha Quadrant. (TAS: "The Eye of the Beholder", Star Trek VI: The Undiscovered Country, production art)
Sensor scans later conducted by the USS Enterprise, supported by several surface contacts, revealed a variety of lifeforms on the planet from such planets as Canopus III and Maravel. Portions of Lactra VII were heavily terraformed, however, not done so in the traditional pattern, as several of the biomes seemed to be patterned at random.
Landing party observations made by the crew of the Enterprise noted that the planet featured several different ecologies co-existing significantly close to each other. One such example included a desert and a rainforest separated by a river. The water discovered on Lactra VII was clear and palatable, but was, according to Spock, "too pure."
