New Subspecies on the Llano?

NOTE: This observation has been further identified as ssp perbellus. So what follows is overenthusiastic reliance on a wrong ID. However, the specimen observed was quite unlike the Echinocereus reichenbachii var perbellus 3 feet away. Different in size and color. It may still constitute a different variety, despite falling within the perbellus range in radial spine count. I let what I posted earlier stand, as follows.

I saw this today on Lubbock Lake Landmark land near the eastern edge. https://www.inaturalist.org/observations/17045482 If the ID holds up, this is the first iNat report of this subspecies on the Llano Estacado. Not uncommon off the Plains; there are many observations of this variety 150 miles east or southeast, but not around here.

Why here, why now?

Of course it may have just been overlooked, though if you have seen many Lace-Hedgehog cacti it does look different at first glance, as though it is endowed with hybrid vigor or better fertilizer. There could be more nearby.

Or, considering this specimen is near the eastern edge of the Lubbock Lake Landmark and near a parking area for the Berl Huffman athletic complex, a seed might have been carried in the mud stuck to a vehicle or on the floor mats of the interior, and washed or blown onto the caliche slopes where the seed germinated. Or a seed could have been carried by a bird or a coyote.

It is something to watch for as you roam the area. Keep a weather eye out for more.

תיאור

This specimen is taller, thicker, greener than typical Lace Hedgehog Cacti. That may not be what it is.

How would one recognize the subspecies? I'm so challenged by cactuses, and can only identify our "usual" species with any confidence.
I rely on https://www.opuntiads.com, and have a copy of Powell, Weedin & Powell Cacti of Texas which was recommended to me. But that book is written for Big Bend/Transpecos.
I know of no cactus expert for the Panhandle/South Plains.

Wolfgangb has just ientified it as ssp perbellus and explained why.

Flowers are very important. When there is no flower and only a photo of one side of the cactus you can look at the spine pattern growing from each node. We used spine pattern in distinguishing Missouri Foxtail Cactus from Viviparous Foxtail, since the Viviparous cactus has long dark spines pointing outward and the Missouri Foxtail has radial spines with only a few pale spines breaking the radial pattern and pointing out.

Another way to ID columnar cactus might be to count ribs if you have a good photo from the top. And of course to look at the ways the ribs are irregular.

But I know none of this. Have a Kew Gardens monograph on Echinocereus (book length, hardbound) that I got for $1 at the used book sale and can't make head nor tail of it. Have a 1970 "Manual of the Vascular Plants of Texas" also bought for a buck 25-30 years ago at the same sale and have only dipped into it lightly. I am the laziest of dilettantes and absorb by osmosis not study, so am the wrong one to attempt to answer.

Quote from Wolfgangb --
"Caespitosus 20-30 radials
perbellus 12-20 radials
this plant 18 radials = perbellus"

Oops! I got all excited over a hasty ID. So "sniff, sniff, never mind" as Gilda Radner or Lily Tomlin used to say.

Please do!! stay alert for that which looks a little different, a little unusual. Sometimes a little hesitation pays off with a novel find
