Sliding down the slippery slope…

In my retirement I want to use photography (and 365) to continue contributing to PhytoImages, http://phytoimages.siu.edu For my own understanding and knowledge, I want to learn about leaf arrangements and the characteristics of flowers and fruits. Here is the first fruit larger-than-a-berry that I have sliced open. It is a cross section of a fruit from the “X Citrofortunella mitis” — http://365project.org/rhoing/365/2014-11-19 — at the University greenhouse.

Looks juicy. Sounds like a great goal.

What an interesting retirement project! And a good use for your photographic skills.

You've got a great shot of what, I don't know. I keep looking at the large seed. Great texture. I looked up your references, too. I'm going to post a quizzical tomato photo tomorrow for your scientific eyes.

Well that answers my question earlier when I wondered how big they were. I see it is quite small.

You are such a student of nature! I sort of am too, but we are interested in different things. You, being a mathematician seem interested in the naming of every type of plant and butterfly and the geometry/structure of things. I am more interested in bugs and spider behaviors....That fruit puzzles me...is it a citrus fruit ?

[Thom Mitchell]

@espyetta A rose by any other name! I don't think I am interested in the naming of things (per se). But you're spot-on with the second part: geometry/structure … and, if I may, *patterns*! This is why the plants-and-flowers and bug posts always have the species in the tags, if available, and the genus … but also the *family*. It's been interesting to see what genera (and species) are in the same families! For example, dandelions and sunflowers are in the same family. :)

@espyetta Is "CITROfortunella microcarpa" a "citrus" fruit? ;)
