I am an emergent embryo; my first stage is a callus. I grow falcate arms with fascicles of wonder. Acropetal messages sing through me and make my body bifid. Adult at last! Abscission occurs and I release my diaspores. Though I am endemic, I am, alas, ephemeral.
All of these words are real. The prompt was “abscission”, a botanical term. I thought why not use other botanical terms. You can find a list on Wikipedia. Oh, I knew what it meant because I’m a biologist, and I know the other words I used. First time being a biologist helped with a prompt. I bet the prompt writer is a botanist.
