''Lophospermum scandens'' is a scambling or climbing herbaceous perennial native to south central Mexico, with red-violet and white tubular flowers and toothed heart-shaped leaves. It grows at elevations between in dry habitats, including deciduous oak forests and recent lava flows. The long-tubed flowers are pollinated by hummingbirds. It has been used in gardens as an ornamental plant since the mid-19th century. Its roots require protection from frost in regions where this occurs in the winter. Hybrids of ''L. scandens'' are also grown. ''Lophospermum scandens'' has been confused with ''Lophospermum erubescens'', partly because the earliest illustration of ''L. erubescens'' was labelled as ''L. scandens''. Among other differences, ''L. scandens'' has a less climbing habit than ''L. erubescens'', with few twining leaf stalks; also the sepals are narrower and joined at the base for rather than only . In horticulture it often appears under the genus names ''Maurandya'' and ''Asarina'', although these genera are now regarded as distinct from ''Lophospermum''. The true ''Maurandya scandens'' is a different species, with shorter flowers and smaller leaves without distinct marginal teeth. ==Description== ''Lophospermum scandens'' is a sprawling or climbing herbaceous perennial with fibrous roots. The long stems are branched, becoming woody at the base with age and developing a woody caudex – a swollen, bulb-like structure at the base of the stem. The leaf stalks (petioles) are long, occasionally twining to grasp supports, thus enabling the plant to climb. The leaves are narrowly heart-shaped, long by wide, with a pointed apex and toothed edges (dentate or crenate). The leaves and stems are sparsely covered with short hairs.〔 ''Lophospermum scandens'' flowers and fruits from May to November in its native habitat. The flowers are borne singly on stems (peduncles) long. The calyx has sepals that are generally narrowly ovate, long and wide at the base, joined for the first . The upper three sepals are somewhat longer than the lower two. The lower margin of the sepals curves outwards along about a third or half its length. The flowers have five petals, joined at the base to form a tube long, whitish at the base and pinkish-red to reddish-violet towards the end. The free lobes at the end of the petals are in two sets: the lower three are shorter, long; the upper two are longer, long, joined to each other for about two thirds their length. Thwo prominent folds (plicae) run along the length of the base of the flower tube, bearing numerous yellow hairs less than long. There are four fertile stamens, the upper two slightly longer than the lower two, and one rudimentary infertile stamen. The style has a cone-shaped lobed stigma.〔 The ovary is hairless and has two chambers (locules). After fertilization, an unsymmetrical ovoid capsule forms, filled with brown seeds, each with a circular "wing" around it.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lophospermum scandens」の詳細全文を読む スポンサード リンク
