Barringtonia racemosa (L.) Spreng. [[http://legacy.tropicos.org/Name/17900318?tab=synonyms|syn.]] Eugenia racemosa L. - Lecythidaceae - powder-puff tree

Evergreen tree, native to the coastal areas of the Indian Ocean, southeast Asia, southern China and Japan, northern Australia, Micronesia and Polynesia.

"Barringtonia racemosa is an evergreen mangrove associate species. It flowers year-long... It is exclusively pollinated by hawk moths. Fruits are single-seeded, indehiscent and buoyant. They are dispersed by ocean currents and seeds upon rotting of fruits germinate within a short time to produce new plants. This tree species is valued for traditional medicine and as an ornamental due to its attractive flowers. ... B. racemosa has been found to display night-time blooming, long and brush-like flowers on long hanging racemes, strong sweet odour emitted from the flowers upon anthesis and moderate quantity of semi-dilute nectar which collectively suggest moth-floral syndrome." \\

"... the floral volatiles of B. racemosa were monitored hourly during its florescence via detached and in situ collection for the first time. The dynamic odor activity value (OAV) was calculated to elucidate the active aroma components of floral scent. Results of compositional analyses showed that the predominant floral volatiles were linalool and phenylacetaldehyde. Their emission started around 8:00 p.m., and the peak emissions were 20541 and 18234 ng/h/flower, respectively, during 10:00 p.m.-2:00 a.m. Results from dynamic OAV profiling revealed that linalool (409/min) and phenylacetaldehyde (547/min) had higher OAVs than other components (<10 min–1), indicating that linalool and phenylacetaldehyde contributed mainly to the floral scent with a strong, sweet, and pleasant aroma." \\
