As far as we have been able to follow the life history of the underground portions of rhizome rooted lilies, we have come to the conclusion that in all the bulbs are annual and are produced in the early autumn when the flower spike is dying. It is usually stated that in some species, _i.e._, _L. Canadense_, the bulbs are annual; but in other species, such as _L. Superbum_, the bulbs are perennial. Perhaps this is usually the case, but it certainly is not so with our lilies. We do not say that the old bulb is entirely destroyed when once it has flowered; a little nucleus is left which sometimes develops afresh into a new bulb. But the tendency of all the American lilies is to run along under the ground, shifting their position every year. The flowers of _L. Superbum_ are numerous. They much resemble those of _L. Canadense_, but are larger, more recurved, and less graceful. They also have the curious green star above referred to. This alone is quite sufficient to distinguish the species from the other swamp lilies. It is a fine lily, and of course a fine plant, but it is not superb, anymore than _L. Elegans_ is elegant. The culture is the same as that of _L. Canadense_. It is, however, a much more satisfactory species to grow. _Lilium Parvum_, the little lily, is a graceful plant bearing numerous small blossoms of a full orange, spotted with black. _Lilium Parvum_ is another misnamed lily, for it often grows five feet high, which is far taller than most lilies. It sometimes bears as many as fifty blossoms. _Lilium Maritimum_ resembles the last, but the blossoms are far fewer, and are of a brick-red colour. Both these lilies resemble _L. Canadense_ in their growth and habits. The bulb of _L. Parvum_ resembles that of _Lilium Pardalinum_ on a small scale. _Lilium Roezlii_, another similar species, bears yellow flowers richly spotted with purple. The bulb is rhizomatous. We figured the bulb of this lily in our October part. _L. Grayi_ we know little or nothing of. We possess a root, but it seems reluctant to flower. The panther lily, or _Lilium Pardalinum_, is the finest of the swamp lilies, Humboldt’s lily perhaps excepted. This lily has so much in its favour that it should be grown by everyone who possesses a soil suitable to its culture. The bulb of this lily is very long, and the rhizome is covered with scales, so that it is impossible to say where the bulb ends and the rhizome begins. It is yellowish in colour, often suffused with pink.
