Q What does Agwa. stand for? What are the parents? How do you spell the complete word? The plant looks like a Zygopetalum.

A What you have here is an Alangreatwoodara, which, as you correctly guessed, is a Zygopetalum relative with Promenaea and Colax, two related genera included in the artificial hybrid. Culture should be similar to that given zygopetalums, which during the winter benefit from extended periods between waterings and not being kept too cool. In the summer, keep warmer (65-85 F) with moderate light. — Andy Easton.
