Does this look like Psidium Longipetiolatum?
« on: September 29, 2022, 12:49:19 PM »
This is a fruit I got off a relatively cold hardy guava that I bought as Psidium Longipetiolatum. I had gotten another plant of this species from jabo45 at some point that is a bit macroscopically different. The latter plant having more rounded leaves. This fruit is from the original plant. Got it here but I don't remember  from who. Fruit was good so no complaints. Similar color inside as outside. What y'all think?







Trying to grow it all!

In my experience idíing robustum and longipetolarum. Robustum has the more robust rounded leaves.
And longipetolatum has the long more lanceolated.
I havenít fruited either but been growing them for 5 years.
I think the fruits will look similar enough to cattleyanum it will be hard to differentiate so good labeling or plant id is crucial.

Isnít the fruit of longipetiolatum supposed to be red?

I had gotten some fruits from my larger Red psidium species but they came out yellow. Supposedly a bit bigger fruits than cattleyanum but is a different species. Looks about the same as the cattleyanums I have otherwise. Either way fruit wasn't red and fruits weren't noticeably larger. Basically the same as my yellow cattleyanum fruits. My actual red cattleyanum seedlings haven't fruited yet. Only around a year old.

I'll try to post a pic of the plant this fruit pictured came from.

P. longipetiolatum leaves are clearly different from P. cattleyanum IMO. P. robustum looks very similar to cattleyanum. I don't have P. cattleyanum anymore, but robustum may have a bit thicker and waxier leaves than cattleyanum. I remember cattleyanum being more coreaceous, like the leaves would snap rather than bend.  Longipetolatum leaves are rounder and bigger, going to heart shaped on mature plants. Since yours flowered, you'd also have seen long (~1 inch) petioles on the flowers/fruit. My guess is P. robustum, but could be yellow P. cattleyanum.
