Paphiopedilum Wellesleyanum var. alba and Paphiopedilum philippinense

Paphiopedilum Wellesleyanum var alba  is a hybrid between Paph. concolor var alba  and Paph. ang thong var alba. This flower has a green spot on the anther cap and the petals/sepals are light yellow in color.

This plant was purchased about 2 years ago and has not flowered since.  The recent cool spell must have triggered it together with Paphiopedilum philippinense below.

Paph. pilippinense do flower here but it is extremely seasonal so it needs the right trigger at the right time.  In nature it flowers around April but i guess in Singapore a sudden cool spell may get a dormant plant to go into flowering mode.  This particular philippinense was in a group of plants i ordered from Taiwan 2 years ago. One type is suppose to have long petals while the other is suppose to have flat petals with no twists.  Lets see how this plant turns out to be.
