Reviewing this specimen again, I think I was too hasty in my initial ID, but looking again closer, the upper surface of the leaves do appear flat, and without a cross-section profile, and these may, or may not, be slightly concave. X. concava profile is triangular to concave by comparison, X. glauca angustifolia is typically square to diamond-shape, and whilst triangular-shaped leaves may also occur in this species, the width of the leaves also looks somewhat broad for the species. Having said this, if it is X. glauca, it is a young specimen, and a plant of this age will not necessarily produce leaf characteristics expected of an adult plant, therefore in my opinion, and without the presence of a distinguishing flower spike, this sighting could be either species, and so remains inconclusive.
