It is found in Oaxaca state in Mexico at 1000-1500 metres, growing in a rich organic soil with some water and some to lots of sun. The caudex can grow to 40 centimetres in diameter, the entire plant to five centimetres in height. The cones are pale brown for the female, greenish brown for the male.
