These two flowers belong to two different plants of P.lamelligeras. One plant was bought from Mr. Joseph Wu (Taiwan) while the other plant was from Mr. Lim Song (Penang).
P. lamelligera generally has bolder markings than the other members of the cornu-cervi family. It also has a unique m-shaped lip. Some taxonomists also quoted differences in the way the flowers are produced on the flower stalk, making it sufficiently separate from P. cornu-cervi which it so closely resembles especially when not in flower.
