Manfreda or Runyon's huaco is a small fleshy plant that looks a lot like an aloe. Its leaves have interesting purplish-brown markings. Also called Tuberose because of its fragrant white to pink flowers which bloom on a flower stalk that sometimes reaches a height of 30 inches. The Mexican people call any plant used to treat snakebite "huaco". The term "huaco" comes from the huaco bird, which was able to cure itself after a snakebite. There are only 4 known populations. Threats to this species include highway and pipeline construction, maintenance, overgrazing, brush clearing, and non-native grasses. Low population numbers and low numbers of individuals could lead to extinction through any number of chance events. (Damude and Poole 1990).
