Aerides houlletiana or falcata (not sure which)

[smweaver]

After taking something of a sabbatical last year and not producing any blooms, this plant decided to make up for it this year by producing two spikes and close to thirty-five flowers. I'm not sure whether this is properly called Aerides houlletiana or falcata. If anyone know what the difference is between the two, would you please let me know? Whatever this is, it's fantastically fragrant.
