p. clxviii Bulbils on Stem of Lilium candidum.—Mr. Saunders also showed one of two similar plants of Lilium candidum grown in a garden at Tunbridge Wells. One of the plants had been growing in rather a damp border, and had not been moved for a long time; the other was in a very dry position, and was moved two years ago. One plant bore three, the other four spikes, each beset with small bulbils in every leaf axil. The foliage was similar to that of other plants of L. candidum growing near by. It was suggested that possibly injury to the apex of the stem had caused the formation of these bulbils.
p. 155 Lilium candidum, Bulbil Generation on. By A. Vigier (Rev. Hort. September 1, 1906, p. 406).—The flowering stems of Lilium candidum if severed just above the soil and treated as cuttings in sand, the floral bud being suppressed, produce numerous bulbils in the axils both in the soil and in the air. It is suggested that rarer lilies might lend themselves to propagation in the same way.—C. T. D.

A Member: You have mentioned this curious business of bulbils, Mr. Chairman. Is there any scientific reason why the cross one way should produce bulbils and not the cross the other way?
The Chairman: You cross with a different parent. I say that X aurelianense crossed with sargentiae will create bulbils. That means that there are two lots of sargentiae. If it is crossed with henryi and there is only one lot of sargentiae, then it does not have bulbils.  On the other hand, X aurelianense, which is a cross of sargentiae itself, never has bulbils. X aurelianense is a cross between sargentiae and henryi.  That grows in the lime perfectly well and it does not have any bulbils, but if it is back-crossed with sargentiae, all the plants have bulbils. If you back-cross it with the other parent — henryi — it does not have bulbils.
