I don't know that anyone can recognize the species from just one picture. Hopefully, you'll recognize the genus from the flower.
I am looking for the name of the very dark purple Oxalis.
I only took one picture.
K. luciae or thrysiflora were two names suggested to me.
This plant is more than a foot wide and almost ready to bloom.
A group of over a dozen.
Same colony as my observation on 2013-09-14.
I'm not sure what this is, it appears to be some tomato relative...
There are a few of these trees growing in Guajome Park. I don't think they were planted on purpose, but I'm not sure if they're native either.
An ornamental tree I've been seeing a lot recently. It has disk-shaped seed pods that split open, releasing lots of small, papery seeds.
