Echinocereus ID
An unlabelled Echinocereus, flowering now. I think it's polyacanthus, but would value some more opinions before printing a label.

Re: Echinocereus ID
It could be E. acifer depending on which book or site you go on.
I'm looking at some pictures here in the book by Blum......
Or polyacanthus v. acifer might be more accepted.

Re: Echinocereus ID
Hi Mike The flower on E. polyacanthus has a bit more yellow in the centre of the flower, in your second photo your flowers looks more like a plant from the scheeria section of the subgenus triglochidiata which does include E. acifer and its four subspecies,of those four the flowers are too small to be ssp.tubiflorus and the new spines on the offset are the wrong colour to be ssp. huitcholensis, the forth ssp. ssp. ventanensis tends to have a more twisted look to the stem so I would go with E. acifer ssp. acifer. also in the first photo all the stems have similar growth shape and type something that does not tend to happen with E. polyacanthus.
( an Echinocereus without a label is a bit like an Opuntia without one, there are so many similar plants , natural hybrids in habitat and cross pollinated species in collections. )

Re: Echinocereus ID
Thanks, Ray.
The stems aren't as chunky as the polyacanthus that I have; triglochidiatus and coccineus are chunkier again, though it's always difficult knowing how representative my (small number of) plants are of the range of variation in a species. This plant is offsetting more than my polyacanthus. The limited amount of paler colouring in the flower throat was the main thing making me unsure of polyacanthus; having looked up acifer now, it does seem to fit much better with this.
Echinocereus acifer will fit better on the label than Echinocereus acifer or possibly acifer hybrid
