Abstract The pollination biology ofIxora platythyrsa (Rubiaceae) was studied in NW. Madagascar. The plant displayed cream-yellow, nocturnally fragrant, nectariferous, tubular and strongly protandrous flowers. These had an “ixoroid” secondary pollen presentation mechanism: prior to anthesis, anthers exhausted their pollen onto unripe stylar heads. From this position pollen of male-stage flowers later adhered to primarily the probosces of small visiting nocturnal noctuid and geometrid moths. — Pollen was subsequently raked off moths' probosces by receptive, copiously papillose stigmas of female-stage flowers. Principal pollination adaptation was probably to the noctuid moth subfam.Sarrothripinae.
