I was wondering if all the broadleaf dicot sporophytes which have thick dicotyledons would be in the Fabaceae family, besides succulents (in other words, what I mean is the seedlings have thicker than usual seed leaves, and their true leaves are much thinner when they develop). I found this picture of an unidentified seedling, for example (possibly a pea plant): File:Seedling-477.jpg - Wikimedia Commons I think "fleshy" must be the descriptive term, instead of "thick", now. I remembered reading that succulent leaves were said to be fleshy, after finding a couple of descriptions of a legume and a soapberry plant for comparison. So it seems that other plant families have seedlings with fleshy seed leaves. Anyhow, I still wonder what seedlings anyone here has identified with fleshy seed leaves (besides succulents), or which would be most common, thanks. I think the ones I've seen look like Prunus avium seedlings, yet there doesn't seem to be a description of those having thick or fleshy cotyledons; well that's what they look like to me. I just had to guess the little true leaves might be in the Rosaceae family, and then look up the seedling based on that in order to find similar cotyledons. Gosh, I haven't found that using morphological terms is all that useful for identifying seedlings. Right, so, morphologically, I must be in the seedy underbelly of a seedling discussion here.
