Mystery Crassula: Stacked Square Leaves, Not Buddha's Temple

Mystery Crassula: Stacked Square Leaves, Not Buddha's Temple

A gardener in Santa Fe saw a succulent with tight stacked square chubby green leaves on vertical stems, very Crassula-like but not opposing angled (even stack). Thought it might be Crassula 'Buddha's Temple' but the plant didn't turn upward like the temple. Seen only in one planter in five greenhouses; rare, not on succulent sites. Wanted to buy some.
