ペラルゴニウム・クラッシカウレ [Index] [Back] アフリカ・ナミビアの南西部から南アフリカの北ケープ州北西部に分布しています。砂漠や乾燥した潅木帯に生え、高さは２０センチほどになります。砂漠地帯ですが、年間を通じて海から立ち込める霧に晒され、また沿岸を流れる冷たいベンゲラ海流の影響で、冬場は霜が降りず、夏場は温暖です。茎は太くて短く、暗褐色をしています。よく分枝して、半常緑の托葉は枝の先端にあります。葉は広卵形で、縁は鈍い鋸歯状で波打ち、銀色の絹のような毛で被われています。６月から１０月ごろ、枝先に総状花序をだし、白地にワインレッドから紫色の模様がある花を咲かせます。 フウロソウ科テンジクアオイ属の半常緑多年草で、学名は Pelargonium crassicaule。英名はありません。 The Pelargonium crassicaule belongs to Geraniaceae (the Geranium family). It is a semi-evergreen perennial herb that is distributed from the southwestern part of Namibia to the northwestern part of the Northern Cape Province in South Africa. It grows in deserts and dry shrubland, and is about 20 cm tall. Although it is in a desert area, it is exposed to sea fog throughout the year, and because of the cold Benguela Current that flows along the coast, it does not get frost in winter and is warm in summer. The stem is thick and short, and is dark brown in color. It is a bushy plant with many branches, and its semi-evergreen stipules are located at the tips of the branches. The leaves are broadly ovate-shaped, with a wavy, bluntly serrated edge, and are covered in silvery, silky hairs. From June to October, it produces racemes of flowers at the tips of the branches, with white flowers with wine-red to purple mottles. 茨城県つくば市「つくば実験植物園」にて、2025年01月25日撮影。 Shu Suehiro shu@botanic.jp
