A rare white flowered individual!

with a few swollen yellow leaf bases, perhaps a gall insect.

This area has a lot of hybrids the skin is candy caned
Definitely not a buckhorn

Does not look like Arizona Pencil Cholla but then again what do I know.. their was a Arizona pencil cholla growing right next to it and talk about a difference

Fruiting

@stevejones this sits somewhere between a pencil cholla and something else I have a idea but I can’t remember

From Canyon Loop hike at Catalina State Park.

Pencil cholla with a growth, deformity, disease, parasite, or ?

Sadly, this invasive species has absolutely destroyed the aquatic habitat of Tanque Verde Creek. Observed from lower falls down to forest service border. Not sure of the full range.
