The Gardeners' Chronicle 45: 57 (Jan 23, 1909)

C. G. Van Tubergen, Jun.

Our Supplementary Illustration represents a hybrid flower raised by Mr. C. G. Van Tubergen, Jun., Haarlem, from a cross between Brunsvigia Josephinae and Amaryllis Belladonna. Mr. Van Tubergen thus describes the circumstances:— "Principally with a view of ascertaining the parentage of the Kew variety of Amaryllis Belladonna (see illustration in the Garden, November 19, 1898, also notes in Gardeners' Chronicle, February 9, 1901, &c), in the autumn of 1892 I artificially impregnated Brunsvigia Josephinae with pollen of Amaryllis Belladonna. Seeds formed freely, as the two genera, Brunsvigia and Amaryllis, are very nearly related. As could be foreseen, with the slow-growing Brunsvigia Josephinae as the female parent, a long time had to elapse before the seedling plants would be strong enough to reach flowering size. After 16 years of patient waiting, two of the strongest bulbs produced flower-spikes in September of last year. When the hybrid plants had been growing for a few seasons it became evident that they differed in habit from the Kew variety of Amaryllis Belladonna, which produces a leaf-stem of about 4 inches high, whereas my hybrids all bear the character of Brunsvigia Josephinae in the foliage, leaves being formed directly above the neck of the bulbs. The infusion of the Belladonna blood is clearly shown in the bulbs, as these resemble those of the Belladonna and produce offsets freely, whilst Brunsvigia never produces offsets. A comparison of the Supplementary Illustration, which was drawn by Mr. Worthington Smith from an inflorescence sent from my garden, with the engraving in the Garden above cited, leads to the conclusion that the Kew plant can no longer be regarded as a hybrid between these species, unless it was a cross effected in the reverse way, taking Amaryllis Belladonna as the female parent. In that case the variety Clanda must have been used, it being the only variety of A. Belladonna known which produces a leaf-stem. The colour of the flowers of my hybrid was a clear, deep rose, suffused with carmine. A single spike produced 22 flowers.
