San Diego County, California, US
edge of pine forest; also immature fruit
Solanum nigrum, growing in eucalyptus plantation
Common in open woodland, Meeting of the Waters Scenic Reserve.
Not flowering, but this has the dark leaves with few lobes that I associate with S. aviculare cf. S. laciniatum.
I'm not sure of the ID, but I'll leave it here as aviculare just in case.
Two plants seen.
On gravel. In karaka grove.
Solanum is a large and diverse genus of flowering plants, including two food crops of the highest economic importance, the potato and the tomato. It also contains the nightshades and horsenettles, as well as numerous plants cultivated for their ornamental flowers and fruit.
