先にも、1月7日付けでセイロンベンケイの花の写真を掲載した。インターネットの写真では、花の根元(上部)が赤く、先から朱色の花弁らしいものが出ているのも見た。他方、わが家の花は、先の写真を撮影したときすでに、つぼみが出来初めてから何日も経っていたのに、黄緑色だけの姿だった。したがって、わが家の植物はそういう地味な種類のものかと思っていた。
ところが、嬉しいことに、最近になって、最も早く大きくなって来ていたつぼみの先端から朱色のものが出て来た(1枚目の写真の中央)。また、日光によく当たっていた側の各つぼみの上部も赤みを帯びて来た(2枚目の写真;このときは、反対側に日が当たるように植木鉢を回転してある)。この植物の花が生長するためには、ずいぶん多くの日数が必要なようだ。[写真はどちらも2011年2月8日、わが家で撮影。]
[掲載後の注記]インターネットで調べたところ、筒状の部分はガクで、先から出る朱色のものが花弁と分かった。
I posted a picture of air plant flowers once on January 7. On the Internet, I saw that the base (at the top side) of some flowers had red color and that there were vermilion things, perhaps petals, at the tip. On the other hand, the flowers in our house had only yellow-green color, although the previous photo was taken several days or more after the start of budding. Thus, I thought that our plant was of such a modest kind.
However, to our joy, vermilion things recently came out from the tip of the bud that had grown earliest (at the middle of the first photo). Further, the upper portion of the side of each bud that had significantly gotten sunlight became tinged red (the second photo; now the flower pot has been rotated for the other side to be exposed to sunshine). It seems that the flower of this plant requires a lot of days to grow up. [Both the pictures were taken on February 8, 2011, at our home.]
[Note after posting] By Internet search, I have learned that the cylinder-like portion is a calyx and the vermilion things at the tip are petals.
