Karanji

The karanji was a type of plant lifeform from the planet Vulcan, a type of plant similar to Earth's barrell cactus. Like most plant life on Vulcan, karanji was adapted to the hot, dry climate there.

In 2253, Spock thought of the karanji when noticing the lush plant life collected in the parklands of Ka'a Beach on Kauai, Hawaii, on Earth. He found it interesting how the water-rich environment allowed for a wide diversity of plants so different from those on his homeworld.
