Of the _Eulirion_ section, the first or _Longiflorum_ group, containing _L. Longiflorum_, _L. Wallichianum_, _L. Philippinense_, _L. Neilgherrense_, and the new _L. Formosanum_, forms as natural a division as is _Cardiocrinum_. But the other members of the _Eulirion_ group are by no means so easy to classify. _L. Japonicum Odorum_ and _L. Brownii_ are very nearly allied. _L. Krameri_, with the new _L. Rubellum_, more nearly resemble the _Archelirion_ than the present group. In certain characters _L. Nepaulense_ nearly resembles _L. Monadelphum_, a member of the _Martagon_ group. _L. Candidum_ bears but little resemblance to the other _Eulirions_. Its flowers are short and numerous, and the bulb sends up an autumn crop of leaves. In the last characteristic it differs very markedly from every known lily. _L. Belladonna_ is unknown to us. _L. Washingtonianum_ and its varieties resemble _L. Candidum_ in bearing numerous small short flowers. Its bulb is very similar to that of _L. Humboldti_ in being an oblique, almost rhizomatose, structure. _L. Parryi_ resembles _L. Nepaulense_ in some particulars, and _L. Washingtonianum_ in others. Its bulb, however, is more like that of _L. Pardalinum_ than that of any other species. Of the _Archelirion_ section, _L. Auratum_ and _L. Speciosum_ have much in common. But _L. Tigrinum_ has but little relation to the former two lilies; its drooping flowers strongly suggest that this lily should be placed with the _Martagons_. _L. Leichtlini_ and _Pseudo-Tigrinum_ are placed among the _Martagons_; yet these two lilies bear a very strong resemblance to _L. Tigrinum_. _L. Oxypetalum_ differs from all other lilies in many respects. It resembles the fritillaries in most points and was formerly included with those plants. As regards the _Isolirion_ group, in which the flowers are erect, we would place _L. Medeoloides_ with the _Martagons_, next to _L. Hansoni_—the plant which it most resembles. [Illustration: _L. Umbellatum._ (Showing abnormal development of aerial bulblets.)] _L. Concolor_ and its varieties should form a group of themselves. _L. Batmanniae_[6] and _L. Wallacei_ should certainly be included with the _Isolirions_, and not with the _Martagons_. [Illustration: LILY LEAVES. (_From a photograph. Quarter diameter._) 1. Leaf from upper part of stem, _L.
