HYBRID BRUNSVIGIA AND X CRINODONNA NOTES, 1961
HAMILTON P. TRAUB, California

The season of 1961 was unusual from the standpoint of flowering dates. During the previous winter season only about 3.5 inches of rain fell and this may have something to do with the results.

Brunsvigia rosea var. major, the early-flowering, many-flowered form of the Cape Belladonna, (and B. purpurascens var. major from Van Tubergen, which is the same plant under a different name), and also X Crinodonna traubii (B. x parkeri x Crinum moorei), and Crinum moorei rosalba, began to flower in the first week in June, and continued on through July. Later other X Crinodonna clones began to flower so that there was a continual bloom on through to October.

One outstanding record for the early flowering of X Crinodonna traubii from seeds was set. From a lot of seedlings of Brunsvigia x parkeri (Zwanenburg Group) x Brunsvigia rosea major, raised from autumn 1959 seeds, one plant bloomed in the last week in June, 1961, about 21 months from seed planting time. This same plant again flowered in October. It is hoped that such performance can be obtained on a greater scale.

VEGETATIVE PROPAGATION OF BRUNSVIGIA ROSEA.Each of two bulbs of B. rosea major were cut vertically into quarters in October 1960, and placed in a pot of sand with the sand between the quarters, and watered regularly. On August 2, 1961, when the cut pieces were removed, it was found that each quarter had produced two bulblet sprouts,. This is a 1-8 increase. Thus in the case of some Brunsvigia x parkeri bulbs that do not make offsets, this method should be tried. It is hoped that Mr. Hannibal and others will report on such experiments in future issues of the Year Book.

CRITERION FOR HYBRIDITY.— In the case of crosses between Brunsvigia rosea or B. x parkeri on the one hand, and Crinum moorei or C. bulbispermum on the other, it is possible to tell soon after the seedling's sprout. The seedlings soon produce several leaves; soon show a true neck and in addition remain evergreen. Seedlings that are not hybrids usually make only a few leaves; do not make a true neck, and go dormant in late spring.
