Are you sure it's not a Fero wislizeni?

NO. Labeled as F covellei at the Los Angeles arboretum.. but if you're sure it's not that, I would be happy to move the photo.

Hi Geoff,
this is the expertise an expert wrote about this photo:
"I have no doubt it is a [i]Ferocactus wizlizeni[/i].
I checked 9 of my specimens from all areas around Tucson and they all have
similar traits.
After checking every image of [i]F. emoryi [/i]I have from Organ Pipe NM I
could find not a one with the whispy whiskery radials. A few had thinner
than usuall radials but never a hint of whisker.

I read Benson and his description of the[i] F. wiz [/i]fruit and the lower
right image in Fig. 5.4 do not jive with the image in 5.6 on page 169.
All of my [i]F. wiz [/i]fruit look like fig. 5.6. I have never seen one
"covered by numerous almost circular, shallowly fimbriate scales,". They
all appear like his description of the [i]F. emoryi [/i]with about 25-35
fimbriate scale like protrutions.
F. wiz seeds ~1/10 to 1/8" long.

I have images of all this if you need them.
The young plants-3-6 years old of the [i]F. wiz [/i]can look very much like
the[i] F. emoryi[/i]. I have those also.

There was a note in Cactus Art...whatever?.... that stated:
"[i]Ferocactus emoryi [/i]has a confused taxonomic history. The name is
based on [i]Echinocactus emoryi[/i], which was published twice by
Engelmann, each involving a different species. Engelmann’s first use of
[i]E. emoryi [/i][in W. H. Emory]---applied to a population of
[i]Ferocactus wislizeni[/i] in eastern Arizona---is rejected as provisional
and therefore invalid. However, Engelmann’s second use of [i]E. emoryi
[/i]was a valid publication, and it unambigously pertains to the species in
southwestern Arizona that Britton and Rose unncecessarily re-named as
[i]Ferocactus covillei[/i]."

Yes, I saw that... I will have it moved. Thanks. Makes you wonder what is going on at botanical gardens that makes them come up with this erroneous identifications, when it seems rather straight forward for someone that knows cacti.
