I was recently comparing some of the seedlings from your supposed P. rivularis, with my confirmed P. rivularis....and I do not believe they are they same species.
the foliage appearance and growth habit is totally different, and the seeds were much larger than they should have been....3-4 times the size of true P. rivularis seeds.
I hope we can figure out what species this is.
Hi ASaffron,
In Brazil, have another Myrtaceae, with the same common name " Guaburiti" , this specie is " Calyptranthes tricona " see this website of a university from Brazil
http://www.ufrgs.br/fitoecologia/florars/open_sp.php?img=82Both species have the same common name :
- Plinia rivularis know as " Guaburiti "
- Calyptranthes tricona know as " Guaburiti "
Sometimes, by reason of both species have the same common name, people think the tricona Calyptranthes is Plinia rivulares
In the pictures of your seedling like a Calyptranthes tricona, see the pictures link of the university,
The fruit is similar too (see the picture in the link of the university ,
http://www.ufrgs.br/fitoecologia/florars/open_sp.php?img=10023 ), but the fruit of Calyptranthes tricona is smaller and darker,
Calyptranthes tricona the fruit is good, the seed is smaller and have a color green inside of the seed
I have thousands of seeds Calyptranthes tricona,
Who want, I can send for anyone for free some seeds
I sold seeds of true Plinia rivularis
