Doctor Watson included this species with those having reticulate bulb coats, but all 
the specimens we have seen (ten or a dozen sheets), including some to which he refers, 
have scaly bulb coats, the inner ones very thin and white or hyaline, the outer some- 
what thicker, yet light-colored. His illustration in the Botany of King’s Survey, 
plate 38, was no doubt made with a compound microscope, since the markings are 
not visible under a hand lens. The illustration of the flower is excellent.
