* Clerodendrum thomsoniae Balf.는 보통 꽃받침이 순백색이나 꽃받침이 연분홍인 것도 있다  Clerodendrum ×speciosum Dombrain도 꽃받침이 연분홍색이어 꽃받임이 연분홍인 C. thomsoniae와의 차이는 알 수 없다. Clerodendrum splendens G. Don은 꽃잎과 꽃받침이 모두 심홍색이다.

Wikipedia 설명

 

Clerodendrum thomsoniae is a species of flowering plant in the genus Clerodendrum of the family Lamiaceae, native to tropical west Africa from Cameroon west to Senegal. It is an evergreen liana growing to 4 m (13 ft) tall, with ovate to oblong leaves 8–17 cm (3–7 in) cm long. The flowers are produced in cymes of 8–20 together, each flower with a pure white to pale purple five-lobed calyx 2.5 cm in diameter, and a red five-lobed corolla 2 cm long and in diameter. The flowers are born in cymose inflorescences arising from the axils of the leaves. The leaves, in turn, are arranged opposite to each other and at right angles to the pairs above and below.

 

An unambiguous common name is bleeding glory-bower; terms like "glory-bower", "bagflower" or "bleeding-heart vine" are also often encountered but can refer to any of the roughly 400 species of Clerodendrum. In some regions it has escaped from cultivation and become naturalised.

 

It is grown as an ornamental plant for its decorative two-coloured flowers. With a minimum temperature of 10–13 °C (50–55 °F), in temperate areas it requires shelter and a frost-free environment.[3] This plant has gained the Royal Horticultural Society's Award of Garden Merit[4] (confirmed 2017).[5]

 

The plant was named at the request of Rev. William Cooper Thomson (1829-22 March 1878), a missionary and physician in Nigeria, in honor of his late first wife.[6][7] This plant was very popular during the mid 19th century under the name "beauty bush". It lost favour only when its unusual culture conditions were forgotten. Specifically, its root system must be partially submerged in water most of the time, and it wants very good light.

 

Etymology

Clerodendrum is derived from Greek and means 'chance tree'.[8]

**** Clerodendrum속 식물의 암술, 수술과 꽃가루받이의 특징

이 속의 식물들은 수술과 암술이 모두 화관 밖으로 길게 돌출하는데(암술이 더 길게 돌출한다) 자가수분을 피하기 위하여 대개 수술이 먼저 성숙한다.. 수술은 꽃가루를 산포하기 전에는 직립하고, 이 기간 중에 암술대는 굽어 있는 상태로 주두가 화관 가장자리 밑에 머물러 있다 . 꽃가루가 산포되면 반대로 수술이 수그러지고 암술대가 직립하여 화관 밖으로 돌출한다.

 

Clerodendrum and its relatives have an unusual pollination syndrome which avoids self-pollination. This mating system combines dichogamy and herkogamy. 

The flowers are protandrous. When the flower opens, the stamens stand erect, parallel to the central axis of the flower, while the style bends over, holding the stigma beyond the rim of the corolla. After the pollen is shed, the stamens curl up or bend over, and the style straightens out, bringing the stigma to the center of the flower
