Bulbophyllum longissimum, first bloom on this one. No credit for me though, it spiked a week after delivery. Small flowers, a mere 26 cm, likely due to this being a three-bulb-division, so hopefully I'll inch my way towards the famed 40 cm flowers in a couple of years.
Scent is freshly gutted fish, slightly pungent. Medium strength; your nose starts reacting some 30 cm (1') away.
