What things start with x in Hawaii?

In Hawaii, items that start with the letter "X" are quite rare, but one notable example is "Xeriscaping," a landscaping method that reduces the need for irrigation, which is particularly useful in the state's dry areas. Additionally, "X-ray" might refer to medical services available in hospitals across the islands. Lastly, "Xenophobia" can be relevant in discussions about cultural interactions in Hawaii's diverse society.
