Dendrobium glomeratum
 

This is my Dendrobium glomeratum (formerly sulawesiense which is now something else entirely), it blooms reliably for me every six months or so. Flowers are very bright pink with an almost fluorescent orange center. Hard to capture the colors with the camera. Sits next to my Dendrobium victoria-reginae in the top shelf of one of my IKEA cabinets.

Love this species. It glows in the sunshine. Camera never quite captures the vibrance of the orange lip against the hot pink segments.
