Other opinions, more or less resembling these, have been formed by other pei'sons, for which I have no room in this place; and they are the less important because I think the plant now before us shows that Kunth's theory is the only one that is correct. If we make a section horizontally through a young flower-bud of this plant, we find the appearances represented at fig. 1. in the accom- panying plate. There is in the centre an ovary of five cells; with these alternate the five stamens, of which the fifth or anterior has a longer filament than the others; so far the structure is regular, and we have all the necessary evidence of the flower, however irregular, being formed upon a quinary type. Right and left of the stamens stand the two innermost jneces; these cannot be simple, because they are oppo- site the intermediate stamens ; but their two-lobed figure, when full grown, shews that each is double, and then, their apparent centre being in fact their united margins, they alternate with the anterior stamens, and so fall into the place usually destined for petals. The last mentioned parts are half enveloped by the hack 'piece, which might, from its position, be the fifth petal; but the case of Hydrocera shewing it really to consist of two united parts, they must be opposite the stamens, and consequently are sepals.
