I have finally come to term with the new name. If it's a cockle shell, we need to recognize it as Ancheilum. This one is found in San Luis Potosi, Queretaro Hidalgo, Puebla, Veracruz, Oaxaca, Tabasco and Chiapas states of Mexico, Guatemala, Honduras and Belize to Costa Rica, Panama, Colombia and Venezuela. Warm to cool growing, I have one in the warm GH and one outside, both are happy. They have had 4 to 6 flowers per inflo but this time only 2.
