Crinum yemense x Hymenocallis macrostephana crossed without any difficulty, as did also Brunsvigia Baptisii x Lycoris aurea. But the most interesting was that effected between an unnamed variety of Hippeastrum and Agapanthus umbellatus. The Hippeastrum flowers here in October and November, but in favourable seasons a stray scape is again thrown up in January and February. It was one of these that made this cross possible; otherwise the pollen of Agapanthus would have to be preserved for a period of ten or eleven months, which is far too long. There were four flowers on the scape when they were pollinated with Agapanthus umbellatus: of these four, one was injured by being too early emasculated, a week before they reached the receptive stage (probably through being produced in the off season). Two flowers perished, but the remaining one produced a full pod of seeds. At this stage, though the seeds were of normal appearance I doubted their fertility. However, they were sown, and nine plants resulted. Three died in the seed pan; but six still remain, which have not yet reached the flowering stage, but are strong and healthy and appear to be evergreen. This being a case of overlapping botanical divisions I never intended divulging it until the plants had flowered. But a recent report that a gentleman near Sydney had effected the same cross has led me to believe that there is nothing remarkable about it.

Email from Hugh Bollinger (2/14/1998)
I've been interested in your comments regarding bi-generic hybrids. The only one I've personally seen, and confirmed as real by an expert authority, was a cross between Agapanthus and Eucharis! I saw the plant and it truely looked like a mix of the two genera. It wasn't in flower when I visited my friend, but he confirmed that it flowered later and had a very strange appearance.

Lilies

Beaton: Propagating stem-rooting lilies (1861)
Mr. Knight made an experiment for getting early Potatoes to seed by planting them on a ridge, and when the plants were ready to bloom he washed away the soil of the ridge to prevent them making young tubers, and so force the whole strength of the plants or roots into the stems and foliage to see if that would force them to seed. Another form of that experiment is applicable to all bulbs and tubers which form roots on the flowering-stems, as the Japan Lilies and others do. Pot such bulbs or tubers with the neck of the bulbs just at the surface, and when the stem is an inch or two put an empty pot over it, introducing the stem through the hole at the bottom of the pot, then earth up the stem, and when it roots and fills the upper pot separate from the bulbs, then cross it.

     Lilium tigrinum x L. elegans Wallacei resulted in every flower operated upon producing huge pods of seed. But when Lilium speciosum album x L. tigrinum, and L. speciosum rubrum x L. tigrinum, and L. tigrinum x L. speciosum album were tried, the results were very different, as the female organ in a very short space of time showed unmistakable signs of decay, and in a couple of days had quite withered. This was so not in one instance only, but the whole forty blooms used in the experiment showed the same symptoms. As evidence that this was no fault of the prospective seed parent, some later flowers were tried, L. speciosum album x L. speciosum rubrum, when they at once returned to fertility. The same thing occurred, only under less favourable conditions, with L. speciosum album x L. auratum, and the same x L. sulphureum. However, under the circumstances I am reluctant to conclude, without farther extended trial, that a union of speciosum and auratum cannot be effected, as so much depends upon what may be termed the seed-bearing mood of the plant, which is often absent when the reproductive organs show the most perfect development.

Lilium testaceum seeding.—In answer to W. Shoolbred in THE GARDEN (p. 194), I once got a good seed-pod of this. It was exactly between Lilium candidum and L chalcedonicum. L candidum and L. testaceum both seeded under the same circumstance: the stems were cut off in flower and put into a pot of water in the open air. It is said if candidum is cut and the stems hung topsy-turvey they will seed.—F. MILES

Day/night temperature environment affects cell elongation but not division in Lilium longiflorum Thunb.
John Erwin, Peter Velguth and Royal Heins
     Lilium longiflorum Thunb. cv. 'Nellie White' plants were grown in different day/night temperature (DT/NT) environments to determine the anatomical basis for differential responses of stem elongation to DT and NT. Lilium plants were forced in 1986 and 1987 under 25 and 12 different DT/NT environments, respectively, with temperatures ranging from 14 to 30°C. Parenchyma and epidermal cell length and width were measured in stem tissue (1987) and epidermal cell length and width were measured in leaf tissue (1986). Total cell number per internode and vertical cell number per internode were calculated. Stem parenchyma and stem and leaf epidermal cell length increased linearly as the difference (DIF) between DT and NT increased (DIF = DT - NT), i.e. as DT increased relative to NT. DIF had no effect on stem parenchyma width, stem and leaf epidermal cell width, or cell number per internode. Data suggested that stem elongation responses to DIF are elicited primarily through effects on cell elongation and not division.
