Not having a Nahuatl dictionary on the shelf -- my Native American linguistic studies were well to the north of that -- I won't attempt to answer the cacomitl query (though I could ask someone else if it's crucial), but I can reply to Dennis's comment, "As for Herbertia lahue being native to Chile... I thought that it was >native to Texas! Is this a different species, or one that is actually >Pan-American ? In "Bulbs of North America," Michael Chelednik writes: "This species occurs in heavy soils of coastal prairies in Louisiana and Texas but also in southeastern South America, a curious distribution shared by a number of bulbous plants including Habranthus tubispathus and Zephyranthes chlorosolen; it has been speculated that all these were introduced from South America, possibly by early Spanish missionaries."
