Information from The Gardners’ Chronicle, March 15, 1902 issue: “Bulb globose, somewhat smaller than that of the mother, covered with thin, light brown tunics. Leaf  linear, light green, not glaucous ; 1 to 1 1/2 ft. long about 1/2 to 1 in. broad. Peduncle shorter than the
leaves, about a foot long, or a little longer, veined with two prominent edges; flowering from February to March. Pedicels irregular, shorter than the spathe. Flowers two or three, closely united, fragrant. Perianth milky-white, ascending, tube funnel-shaped, green on the base outwards ; segments concave, acute, as long as the tube; corona cup-shaped, truncate, about half as long as the segments, milky-white on their base, sulphur-yellow on the upper part. Stamens and style variable, the latter much shorter than the stamens. Quite sterile, as I believe.
