Satyrium longicauda var. longicauda almost white flower

The broad mouth of this Satyrium longicauda var. longicauda flower has the frilled upper margin of the lip and less frilled margins of the lateral petals around it, all in white. The slightly sagging, smooth-margined lateral sepals are tinged pink near their tips, as is the median sepal below (Manning, 2009; Pooley, 1998; iNaturalist).
