 Rothmannia annae (E. Wright) Keay - syn. Gardenia annae E. Wright - Rubiaceae - Wright's gardenia
-Small tree, endemic to the islands of Seychelles.
+Small tree, endemic to the islands of Seychelles, now restricted to Aride islands.
+"The causes that led to the extinction of this species on Mahé, Silhouette, Praslin and Félicité are not fully understood. It is possible that introduced insect pests caused the rapid extinction. A similar event could drive the remaining population on Aride Island to extinction. This species is listed as Critically Endangered." \\

 "Historically, it was widespread in the islands but has been restricted to the Aride islands since the early 20th century... Its decline on most islands can be attributed to clearance of the lowland forests... The heavily scented flowers may be produced in all months, particularly after heavy rain." \\
-Flowers are white, sparsely of heavily spotted; white and sparsely spotted flowers are predominately male. Fruit set is only 5% of the flowers.\\

-"The attractive flowers emit a rich aromatic, white-floral scent, reminiscent of aspects of orange flowers, carnation, and tuberose, which is at its peak during dusk. Of special importance to this scent are methyl benzoate (48.0%), 2-phenylacetaldehyde (1.4%), methyl salicylate (4.1%), 2-phenylethanol (15.9%), eugenol (0.02%), indole (1.6%), and (E)-2,3-dihydrofarnesal (0.1%)" [headspace analytic data as present in Appendix added A.K.]\\
