Terscheckii confusion

ok, so heres a little gem i just picked up at walmart, it had a straw flower glued on it that i had to rip away, figured it was either a browningia or trichocereus terscheckii. but i see alot of variation in the latter so its hard to know what is the real thing.
  here it is along with other suspected members of this group
 heres a seed-grown terscheckii. next to it. asim USED to seeing
 heres A plant I bought as "trichocereus shaferi" but always assumed was terscheckii.
 and heres an unmarked plant I bought with a rotted meristem that i chopped off to offset (its been a year, still waiting) that i also assumed was a terschecki.
 now im scratching my head wondering whats what. any enlightenment?

The Trichocereus Key
STEP 1
Are the stems basically erect and "more or less" branched? If yes, go to Step 1.1
Are the stems "simple", low to the ground and growing in clusters? Go to Step 2.1
STEP 1.1
Are the limbs of the flower broad? Go to Step 1.1.1
Are the limbs of the flower narrow? You have a TRICHOCEREUS FASCICULARIS (aka Weberbauerocereus fascicularis).
STEP 1.1.1
Are the joints relatively slender, 2 to 3.5" (5 to 9cm.) thick? Go to 1.1.1.1
Are the joints stout (sturdy)? Go to 1.1.1.2
STEP 1.1.1.1
Are the ribs scored by longitudinal furrows between the areoles? Go to 1.1.1.1.1
Are the ribs NOT scored by longitudinal furrows between the areoles? Go to 1.1.1.1.2
STEP 1.1.1.1.1
Are the tubercles (small knobby projections) prominent? You have TRICHOCEREUS THELEGONUS.
Are the tubercles (small knobby projections) NOT prominent? You have TRICHOCEREUS THELEGONOIDES.
STEP 1.1.1.1.2
Is there only one central spine? You have TRICHOCEREUS SPACHIANUS.
Are there 4 central spines? You have TRICHOCEREUS LAMPROCHLORUS
STEP 1.1.1.2
Are the ribs on old plants very numerous and the spines bristle-like? You have TRICHOCEREUS PASACANA (or Helianthocereus pasacana).
Are there 4-17 ribs? Go to 1.1.1.2.1
STEP 1.1.1.2.1
Are the spines slender, .4 to 2.75" (1 to 7cm.) long? Go to 1.1.1.2.1.1
Are the spines very stout and "formidable"? Go to 1.1.1.2.1.2
STEP 1.1.1.2.1.1
Are there 4 to 9 ribs? Go to 1.1.1.2.1.1.1
Are there 16 or 17 ribs? You have TRICHOCEREUS CHILOENSIS (aka TRICHOCEREUS CHILENSIS).
STEP 1.1.1.2.1.1.1
Are the spines yellow, at least when young; are there 4 to 8 ribs? You have TRICHOCEREUS BRIDGESII.
Are the spines brown from the first: are there 6 to 8 ribs? Go to 1.1.1.2.1.1.1.1
STEP 1.1.1.2.1.1.1.1
Is the plant dark green; are the spines few or wanting at each areole? You have TRICHOCEREUS PACHANOI.
Is the plant light green; are there several spines at each areole? Go to 1.1.1.2.1.1.1.1.1
STEP 1.1.1.2.1.1.1.1.1
Are the spines shaped like a needle and up to 1" (2.5cm) long or less? You have TRICHOCEREUS MACROGONUS.
Are the spines linear and tapering to a fine point, up to 2.75" (7cm.) long? Go to 1.1.1.2.1.1.1.1.1.1
STEP 1.1.1.2.1.1.1.1.1.1
Are the spines swollen at the base, is young growth green? You have TRICHOCEREUS CUZCOENSIS.
Are the spines NOT swollen at the base, is young growth lighter, having a waxy/frosty appearance? You have TRICHOCEREUS PERUVIANUS.
STEP 1.1.1.2.1.2
Are the spines dark brown? You have TRICHOCEREUS COQUIMBANUS.
Are the spines yellow? You have TRICHOCEREUS TERSCHECKII.
STEP 2.1
Are the flowers short, red or yellow and more or less bell shaped? You have TRICHOCEREUS HUASCHA (aka Helianthocereus huascha).
Are the flowers elongated, funnelform, white? Go to 2.1.1
STEP 2.1.1
Is the tube longer than the limb, are there 12 to 18 ribs? Go to 2.1.1.1
Is the tube about the length of the limb? You have TRICHOCEREUS SCHICKENDANTZII.
STEP 2.1.1.1
Is the stem slender, elongated? You have TRICHOCEREUS STRIGOSUS.
Is the stem stout, short? You have TRICHOCEREUS SHAFERI.

These keys are totally useless, sorry.
Mitch: indeed there´s a lot of variation. Your new plant does almost look like a ferocactus, but ferocactus have reddish spines. I´m afraid I can´t help very much, with seedlings it´s always like this, we can never know for sure.

I don't think it's Trichocereus.
But maybe.
Wait till it grows.

Wait...are you saying it's a T. Candicans, now?
I really don't think it's Trichocereus...Look how the spines are hooked.

There are Trichocereus with hooked spines, T. chiloensis for example.

no, im saying the one with he curved spines (not hooked BTW) is a terscheckii, the one that is candicans in the same pic is on the left.
it was actually given to be as a seed-grown "bridgessi" long ago, but clearly it is not that.
