the phitrantha i named Sanford, came out of a batch of aureana seeds from Oscar in HI, and I believe he imported them from Brazil and resold them to me. I just assumed it was a stray phitrantha seed that got thrown into the mix.
the Sanford tree is unique in terms of foliage, and growth habit, but it reminds me of ESALQ, and other phitranthas I've tasted.
the hybrids that tickle my fancy, are the ones where the parents are more distantly related.
for example, Phitrantha x Grimal, Red x Trunciflora, Anomaly x Grimal, Red x Grimal, Sabara x Grimal, Sabara x Phitrantha, and so on...
Thanks Adam and there is always more to a story. I have costada and know it. It has a different growth pattern and foliage and the fruit are smaller but yes there is a resemblance in the fruit appearance. The reason I assumed some had outcrossed to phiitrantha is that the outdoor planted parent my Brazilian friend had was in close proximity to several phitranthra which he also had growing.He did confirm that all in the batch sent came from aureana when I enquired and there was no mixup.
I will say that I really don't believe aureana and phiitrantha are different species but are just at different ends of a spectrum of tree size and fruit colour etc of a single species. Since both forms and all in between exist only in cultivation and not in the wild some may question the validity of both of these species anyway as stand alone entities.
