This specimen may be X. johnsonii, however this observation may be X. glauca or possibly X. malacophylla. The crowns are very full and heavy, the tall specimen in the second image looks to have at least two crowns, and although X. johnsonii may develop multiple crowns, the species is largely unbranched and simple. Without the presence of any flower spike, leaf close-up, leaf colour or cross-section profile, I can detect no specific characteristics that can determine these specimens to species level. This sighting appears inconclusive based on these images. Tapirlord, out of interest, what identification markers did you use to ID these as X. johnsonii?
