Many thanks for your suggestions teague. I have had a look at both but am unable to find a match. I think the hunt goes on.
Thank you teague for this suggestion. Trouble is my plant has just 5 stamen..(5 petals)..see close up below. All the Casearia flowers on line have multiple stamens. casearia flowers - Google Search: Sorry I think the search goes on.
Update......Latest.....Hot of the forum! On another forum I have just been told by GreenTara18".. from Russia, Moscow that it is Acnistus arborescens. It looks a perfect match...and is found in Costa Rica. Acnistus arborescens - Wikipedia Quote......Acnistus arborescens is a species of flowering plant – the single species in the monotypic genus Acnistus, belonging to the Nightshade family Solanaceae. Common names include gallinero ( = 'henhouse' ), mata-gallina ( = 'chicken-killer' ), fruta-de-sabiá ( = 'thrush-fruit' ), hollowheart, wild tobacco, siyou, bastard sirio, galán arbóreo, tabaco de monte ( = 'mountain tobacco' ), nigüito, marieneira, güitite, and tabak djab ( = 'devil's tobacco' )" Acnistus arborescens (Solanaceae) image 2054 at PlantSystematics.org I am happy to have it solved!
I am thrilled that you were trying to id this for me. Much appreciated. I have the feeling that GreenTara18".. from Russia, Moscow is another Lila, or Tyrlych or Ron. I never even thought of Solanaceae.....Duh! Still learning! Just wish I could remember the names..remember what plants look like and often exactly where I have seen them...but names...err no chance. Please can you try the 5 red berries. That is bugging me. Cheers S.S.
