NEW HYBRID HEMEROCALLIS.
Charles Sprenger, Vomero, Naples.

In my garden at the Vomero I cultivate all the Hemerocallis and Funkias which I have been able to obtain, including all those known in European gardens. They flower here from the end of April until November. H. minor and Dumortieri are the first to flower, and the fine aurantiaca blooms from April to November, being thus the first and also the last. I cultivate them all in the open ground and in full sun, giving much water and manure. When the plants first came here all were completely sterile, and I lost all hope of fertilising and hybridising them. But little by little some of them showed the lost quality of seed-bearing, and finally some new importations from Central China made it an absolute certainly that it would be possible not only to grow seeds but also to hybridise the plants, and now the result is very promising, and we have some fine hybrids.

Up to the present we have had seeds from the following species and varieties:—

Hemerocallis minor. Mill.
" Thunbergii, hort. Lemoine.
" citrina, Baroni.
" fulva maculata, Baroni.
" aurantiaca major, Baker (?)

The remainder are still sterile, but give pollen abundantly. We have hybrids of the following:—

H. citrina x aurantiaca major
" x fulva maculata
" x Thunbergii
" x minor
" x disticha
" x disticha fl.-pleno
H. aurantiaca major x citrina
" x fulva maculata
H. Thunbergii x citrina
" x aurantiaca major
" x minor crocea
H. minor crocea x Thunbergii
" x citrina

If sown immediately after ripening the plants or seedlings flower here during the third year, and some of them after the fourth year. We water and manure them abundantly, for they are always thirsty and hungry. Here is a short but concise description of my first fine and interesting hybrids:—

1. HEMEROCALLIS VOMERENSE (Thunbergii x minor crocea).—Leaves about 2 feet long, and. very narrow, deeply canaliculate, light green. Stein more than 2 feet long, with eight to ten very fine sweet-scented, canary-yellow flowers borne April May. The outside of the flowers is a little more darkly shaded. A fine hybrid, exactly midway between its parents. It is not sterile, but produces perfect seeds.

2. HEMEROCALLIS ELMENSE (minor (graminea) x citrina).—Leaves about 2 feet long or longer, concave, light green, loose; very stoloniferous. Stem about 3 feet long, bearing ten to twelve or more flowers of s brilliant canary-yellow, very large, widely opened, sweet-scented; trunk bright green, tube very long, flowers April-May, and is useful as a cut flower.

3. HEMEROCALLIS x HIPPEASTROIDES (Minor crocea x Thunbergii). — Leaves about 2 feet long, narrow, elegantly recurved, light green; stem 2 1/2 feet long, with about ten or more very handsome, widely-opened flowers with star-like horizontal petals, brilliant sulphur-yellow, and sweet-scented. A magnificent variety that flowers in May and is exceedingly elegant.

4. HEMEROCALLIS x PARTENOPF (Thunbergii x aurantiaca major).—Leaves about 2 feet or longer, narrow, concave, fresh-green, a little shaded with gray outside; stem cylindrical, slender, with many leaves, and ten, sixteen, or more flowers. These are large, like a Lily, canary-yellow, sweet-scented, with undulate petals. A very fine hybrid, producing seed abundantly, and exactly midway between its parents.

5. HEMEROCALLIS x BARONI (Thunbergii x cltrina). —This flowered first on June 20, 1903. Leaves about 2 feet or longer, concave below, undulate on the upper surface, like the leaves of Citrina, and pink on the lower part; umbel widely spreading, with many flowers, which open in the evening or about 4 o'clock, and are sweet-scented, very large, with the inner petals larger than the outer, and a very long, light-green tube. The stem is elegant, slender, and about 3 feet in height. A splendid hybrid, with canary-yellow flowers.

6. HEMEROCALLIS x OCHROLEUCA (Thunbergii x citrina).—Flowered first on June 21,1903. Leaves about 2 feet long, narrow, concave on the lower surface, undulate, fresh-green; stem more than 2 to 3 feet in height, slender, much ramified; flowers open at 6 o'clock in the evening, remaining so during the following day, sweet-scented, large, deeply sulphur-yellow, with gold anthers, and a short, greenish tube. A splendid hybrid, and one of the finest of all the Hemerocallis.

7. HEMEROCALLIS x MÜLLERI (Thunbergii x citrina). Flowered first on June 25, 1903. The very fine, large flowers open at 4 o'clock. The leaves are like those of the pollen-parent (H. citrina, sent from Central China by the late Padre Givaldi, and named by Prof. Baroni, of Florence), are narrow, concave, and undulate; stem 2 feet long, always cylindrical, but somewhat angular, not much divided, but with about fifteen flowers or more In the umbel. The flowers are very large, with large petals, sweet-scented, canary-yellow, with a long, greenish-yellow tube and golden anthers. This is, so far, the finest of my new hybrids.
