Think Ive been had.

I  purchased seeds of what was supposed to be casimiroa sapota aka matasano from rarepalmseeds. Now this plant is closely related to casimiroa edulis. I have been told seedlings should be pretty much the same. Have a look at the pics. The seeds didnt look quite the same as white sapote but were old.  I also put them in ga3  but that doesnt account for milky white sap. Im guessing sapotaceae. Not pouteria as the seeds are wrong but im after opinions.

Actually it does resemble a lot a Canistel.

Yup, but the seeds are totally wrong for any pouteria sp ive seen and ive grown over 20 of them. They look like a football shaped walnut.

Like this?

This is mammea, but leaves looks different.

[druss]

You might have it. The seeds look suspiciously like these.

Casimoroa seeds are white on exterior and fairly smooth. Mammee apple seeds are huge, about 4x as big as casimoroa, flattened shape, ruffled on exterior, and brown.

These seeds are the same size as a casimiroa, similar shape, but have a walnut grain shell. Will try get a better closeup tomorrow.

The seeds

Couepia sp. ?

I think it isn't a scientifically valid species anyway and seeds should look like the standard white.Even tetramera seeds look the same and that probably isn't a valid species also. They are not seeds in that genus but they look sorta familiar.Maybe not Couepia unless it is a species I haven't seen the seeds of. Lecythis maybe.

Im actually starting to think Bertholletia excelsa.

[Guanabanus]

The picture of the seed in the pot looks like Canistel, with the testa (seed coat) removed.   But I don't recall seeing any that looked ribbed, as in one of the lower photos.

What you see in the pics is a very hard shell with the seed inside of it. Will cut one in half.

Doesn't look like Lecythis I have seen.

Okay this is interesting. Just purchased these. In real life they look identical to the supposed casimiroa sapota seed.  But old pics on the board of pouteria hypoglauca/glomerata don't match this. Are these cinnamon apple seeds?

there is more on the page
but, i would assume the seeds would look very very close to White Sapote.

------------------
Several taxonomic and biological questions are associated with the Matasano (one of the common names applied to Casimiroa spp. in Mexico and Central America).  The first problem is with the scientific name:  our Manual treatment originally used the name C. edulis La Llave & Lex., with C. tetrameria Millsp.—the name used by Standley for Costa Rican plants in his Flora of Costa Rica—as a synonym.  No mention was made of C. sapota, which, according to the Flora de Nicaragua, occurs in Nicaragua and in Costa Rica, and is distinct from the Mexican C. edulis.  In this respect, Flora de Nicaragua follows the work of M. Martínez (Las Casimiroas de México y Centroamérica.  Anales Inst. Biol. Univ. Nac. México, Bot. 22: 25–81.  1951).  According to Martínez, C. tetramería is endemic to the region of Yucatán, Mexico, and only C. sapota has been collected in Costa Rica.  The purported difference between C. edulis and C. sapota is the longer and thinner petioluoles of the former, even though Martínez gives no measurements for thickness and, over all forms and varieties, any difference in the stated length of petioluoles is nil.  Nevertheless, the type of C. edulis is from Mexico and that of C. sapota is from Nicaragua, and based just on type images, the Costa Rican material does resemble more closely C. sapota.  To finish this already too-long story:  without a more thorough revision of the genus, we can do no better than follow Martínez and the Flora de Nicaragua in using the name C. sapota for the Costa Rican material.

Cinnamon apple and white sapote seed look totally different.
Here is a photo of cinnamon apple seeds, very unique looking seeds.
