This observation is for the galls in the stem. I’ve collected a couple of these so I can see what emerges.

awblairDescripción
These were all past flowering. Another example of the tall form of entire-leaved Silphium with ~dense leaves all the way up the stem that are found in riparian/floodplain habitats in the Hill Country. In the past, I had called these S. asteriscus though I honestly have no idea now. They are quite distinct from the upland forms I've seen in the Hill Country (S. gracile?) and those growing in sandier soils on the coastal plain (S. radula?).

trevorzookDescripción
What's going on here? Potential hybrid of S. laciniatum and S. perfoliatum, or just strange S. perfoliatum? Very deeply cleft leaves that are not connate. Lower cauline leaves only slightly clasping with long petioles. The stems are square at the base and round more than 18" above the ground, and pubescent where square only. The one stem with lower leaves alternate instead of opposite has a round stem throughout. The underside of the midvein is pubescent. The second to last picture is me holding a flower of nearby S. perfoliatum (left) and S. laciniatum (right) against this plant's flower (top), showing the larger size.

S. laciniatum and S. perfoliatum hybrid or just weird S. perfoliatum? Further notes in @trevorzook 's description.
Last photo with three flowers in the hand compare nearby S. perfoliatum (bottom right) with S. laciniatum (top right) and the plant in question (left)

Alternate leaves; basal leaves rounded/cuneate- not cordate; ray flowers showing 11 on photo but likely one missing; other similar Silphiums have opposite or whorled leaves. S. Radula is west of the Mississippi River

This gall had the whole flower drooping to the ground and weighed about as much as a walnut. The mosquitoes were terrible so I didn’t linger and hope to return for another look soon.

Extensive population consisting of thousands of stems across multiple acres. Plants do not have well developed cauline leaves. However, many basal leaves do not have an pinnatifid structure.
