Growing in part shade along the South Fenceline Trail just beyond the first house. Sandy soil in a section of Post Oak/ Loblolly Pine woods that was moderately burned in August. A single stand of this plant is growing beside Solanum emulans, Paspalum plicatulum, Pinus taeda, Ilex vomitoria and Phytolaca americana. Flower heads with five white disc flowers and sessile leaves that are serrated in the distal half.

Photo 5 shows leaf underside with golden resin dots at 14x magnification which is in part determinative for the species. The last photo shows the seven florets per flower head also at 14x magnification.

What a great day trip to Houston! I was led by botanical guru (and City Nature Challenge species dominator!) Andy Newman -- the mission: find as many species as possible. I wish I would have taken some better photos...

This final stop for the day was roadside to see some Rayjacksonia aurea and Chloris texensis in a really unique barren. Lots of other cool plants were spotted here too. Hopefully the invasive grasses don’t completely take these areas over…
