达尔文的兰花

 达尔文的兰花

Charles Cook

1862年,查尔斯-达尔文从一位园艺家和外来植物收藏家詹姆斯-贝特曼那里收到了一箱植物,其中有一个特殊兰花的花的标本---。 芝麻开门 达尔文在给一位朋友的信中写道:"我刚刚收到贝特曼先生寄来的这样一个盒子,里面有令人震惊的 芝麻酱 [原文如此],花蜜有一英尺长,天哪,什么昆虫能吸住它"(翻译过来就是 "我刚刚收到贝特曼先生寄来的一个盒子,里面装着神奇的Angraecum sesquipedalia,花蜜有一英尺长,大约30厘米。 天哪,什么昆虫能吸住它")。

ǞǞǞ 芝麻开门 是马达加斯加特有的兰花。 它们生长在低海拔地区,依附在岛屿东海岸的大树或岩石上。 该植物呈单株生长,叶子很厚,纵向折叠,呈扇形排列。 从叶子的底部冒出的花茎上有1至3朵大的星形花。 当它们开放时,是白色的,带有阴影的随着它们的成熟,它们会发展出一种乳白色的吸引力。 花朵可以达到16厘米,著名的蜜腺有30至35厘米长。

达尔文的发现

在第一封信的几天后,达尔文给他的朋友回信,他在信中说:"在马达加斯加,应该有飞蛾,其长柄足以伸展到10至11英寸(25.4-27.9厘米)之间"。

这个关于昆虫--飞蛾的预言在当时的科学界很有名,一些人接受,许多人嘲笑,因为在马达加斯加没有这种动物。 1907年,在达尔文死后大约20年,在马达加斯加发现了一种夜行性蝴蝶,从翼尖到翼尖大小为16厘米,长有一个卷曲的长鼻,但达到20多胀大时长达厘米。

但是,有可能出现一种动物,能够以隐藏在花蜜底部的花蜜为食,这是一回事。 芝麻开门 而这一事实的文件证明在1992年才成为可能,当时人们有可能拍摄到飞蛾从长长的蜜腺中吸食花蜜的情景。 芝麻开门 达尔文预言,这种兰花的花和蝴蝶是共同进化的,或者说是共同进化的,因此双方都会从这一事实中受益,飞蛾以花蜜为食,兰花被授粉,这在昆虫的名字中得到了永生、 燎原菌(Xanthopan morganii praedictae) 巨型刚果猎鹰蛾的一个亚种。 这个词 褒义词 显然与达尔文的预言有关。

2009年,全世界用无数的展览和会议来庆祝达尔文诞辰200周年。 在古尔班基安博物馆,葡萄牙人能够看到有关达尔文的宏伟展览。 那一年,我参加了伦敦的兰花展览,那里的壁画也讲述了达尔文预言的故事。 还有什么更好的日期让我买到这种具有如此多历史的兰花呢?当然,我带了一个小副本供我收藏。

如何成长

ǞǞǞ 芝麻开门 兰花通常生长在花盆或吊篮中。 应放置以松树皮和椰子纤维为基础的兰花基质,并可添加一些Leca®以确保良好的排水。 粘土或塑料制成的花盆不应太大。 它们也可以安装在软木或树干上,但由于植物可以大幅增长,它们可以达到1它们喜欢少有阳光直射的中等光照,空气中湿度充足,经常浇水(每周1-2次)。 它们还喜欢温带环境--理想温度可在10至28摄氏度之间变化。

这六年来,我的标本一直放在有暖气的温室里。 它是如此特别的植物,我担心如果我把它放在外面就会失去它。 它一直在生长,没有开花,直到大约一个月前,它开始长出穗子,慢慢地出现了两个花蕾。 第一个花蕾打开了,两个星期后是第二个。 它们对栽培要求不高,在我们国家很好。 我知道有半打我的植物今年首次亮相,开了两朵花。 花期结束后,它将被重新栽种,我希望它不会再过六年才再次开花!"!
