Need to revisit in flower to confirm I.D. since it may have been planted originally but is now naturalizing

Image #1
Morphological comparisons of both Opuntia cespitosa Raf. (Left) and Opuntia humifusa Raf. (Right) observed at Rondeau Provinical Park on September 22, 2023.
Image #2:
Observers should note the (extremely) subtle differences between areole cross-sections and glochid formations of both species.
Image #3:
Opuntia cespitosa Raf. (Top) produces oblong fruiting bodies whereas Opuntia humifusa Raf. (Bottom) produces obovate fruiting bodies.
All suspected O. humifusa Raf. occurrences should be monitored from June-August to verify the production of wholly yellow blooms.

Prairie Pricklypear (Opuntia macrorhiza)Observer
rednaxDescription
Found growing out of a gravel driveway. Multiple patches are there, and they seem to be fairly well established. I think I saw three patches with maybe half a dozen paddles each.

derekstephenhollingsheadDescription
Multiple reflexing or deflexing radial spines per terminal areole. Notable glochid features when compared to hundreds of O. cespitosa observations taken across Ontario. There are notably more areoles per diagonal cross-section of a given joint when compared to hundreds of Ontarian O. cesptiosa observations. Tuber-like roots were observed. Red obovate fruiting bodies were also observed.

Quite resembles O. humifusa except for the abundance of short spines in varying numbers on each cladode. Spine groups either single, double or triple, possible more. Glochids are quite pronounced in some pads.

Large 8inch plus cladodes, most with at least one spine, many cladodes have multiple spines in groups of 1, 2 and 3. Large and numerous along this path.

Carolina Prickly-pear Cactus (Opuntia tunoidea)Observer
dcvmnaturalistDescription
Read in another report that this species was naturalizing itself in the dunes. I found the exact plant from the previous report. This cactus has large obviate pads with short spines along the edges of the cladode. Spines approximately 1/2 inch. This plant is likely a discarded pad of the very large cultivated cactus in the backyard of the house on the corner. I searched all public accessible areas nearby and did not find any others. What I found was a lot of O. humifusa.

Temporary placement here based on the Intermountain Flora Vol 2A key. This plant was unlike any other Opuntia in the area i.e. it was not part of a population of similar plants. Have not seen flowers/fruits.

Flora
Esta planta es capaz de crecer en suelos salinos y áreas costeras, donde muchas otras especies no pueden sobrevivir. Como resultado, desempeña un papel crucial en la estabilización de suelos costeros y en la protección contra la erosión. Además, proporciona hábitats importantes para la vida silvestre. Su capacidad para tolerar condiciones ambientales adversas lo convierte en una especie importante para la restauración de ecosistemas costeros degradados.
