The bulbs of _L. Elegans_, _L. Bulbiferum_, _L. Croceum_, and _L. Umbellatum_, and others usually remain pure white. _L. Longiflorum_ and a great many others become of a yellowish tint. _L. Speciosum_ and _L. Auratum_ usually become a dark brown or purplish colour. The bulb of _L. Giganteum_ is usually a deep russet colour. Lily bulbs vary greatly in shape and structure. The typical bulb is ovate or pyramidal in shape, with small regular scales. There are many variations from this. Some are more or less rounded, others, notably that of _L. Polyphyllum_, are very long and narrow. Some have large flat scales, whilst in others the scales are small and rounded. Some bulbs, such as those of _L. Superbum_, _L. Canadense_, and many others, are borne upon a perennial rhizome, the bulbs themselves being annual. The bulbs of _L. Humboldti_ and _L. Washingtonianum_ are curiously unlike those of any other lilies, being flat and oblique. Some bulbs possess a large number of minute scales, others have but a few large scales. The bulbs of _L. Roseum_ and _L. Hookeri_ are invested with a dense membranous sheath like the bulbs of the tulip. No other lily bulb possesses this sheath. These are some of the varieties of lily bulbs; an accurate description of most will be found in connection with the accounts of the various species. The stem of the lily is usually straight and unbranched. Very rarely the stem is branched. It varies in diameter and toughness in the various species. In some species it is covered with down. The leaves are subject to even greater variety than is the bulb. They may be few or many, arranged in whorls or scattered, and of various colours and shapes. _L. Chalcedonicum_ has many hundred leaves, whilst _L. Auratum_ rarely has more than thirty. In some lilies, such as _L. Washingtonianum_, _L. Humboldti_, _L. Martagon_, etc., the leaves are arranged in whorls, but in most kinds the leaves are irregularly scattered. In colour the leaves of the lilies present much variety. Usually the leaves are deep glossy green. In _L. Longiflorum Foliis Albo-Marginatis_ the leaves are pale green bordered with white. In one variety of _L. Candidum_ they are edged with yellow. Lily leaves are usually linear or lanceolate; but they vary in shape from the thin pine-needle-like leaf of _L. Pyrenaicum_, to the broad heart-shape leaf of _L. Cordifolium_. Usually but one kind of leaf is present, but in _L. Giganteum_ at least three distinct forms of leaves are developed. And in _Lilium Candidum_ the autumn or base leaves are totally distinct from the linear leaves borne on the stem.
