Looking to identify this "Fishhook Cactus"

[AllenK RGV]

I was thinking it belongs under "Echinocactus" but I am striking out there. Do we have any Cacti experts here?

I have around 5 of these on the property, their tuna form bright red peas about 1x2cm in size(WxH). Flowers are long lasting and open during the day and close at night. IMG_4842 might be a "Ferocactus". Anyone that can help ID is certainly welcome to one of the pips as seen in IMG_4841. Location information is in my profile.

Size is important in identifying plants. It would help to place a familiar object next to the subject when photographing it. It's a gorgeous flower.

My little flower will open back up around noon, and here are the photos as suggested. Every measurement is in inches.

Thanks for the link I had been surfing there for several others that were easy to ID. Just with these I'm drawing a blank or hitting up the wrong genuses. Bot haven't checked Mammallaria that looks promising.

helocactus setispinus I created an account at cactiguide.com and it is common in cultivation heck ebay for it starts around 5 dollars plus shipping. I didn't win the lottoat least it is pretty.

Yes, the flowers are the only enjoyable thing about cactus. I'm always pilling out spines from my hands after working around my place.
