So yesterday, March 1st, 2026, I encountered an impressive plant on the E4 European long-distance path, on Mount Olympus, near Litochoro. Here is some information I have gathered online about it:<\/p>\n\n\n\n

Lathraea squamaria<\/em>, commonly known as Common Toothwort<\/strong>, is one of the most peculiar and “mysterious” plants of the European flora, including Greece.<\/p>\n\n\n\n

It belongs to the Orobanchaceae<\/strong> family and its behavior classifies it as a parasitic plant<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

1. Biological Characteristics<\/strong><\/h3>\n\n\n\n

The most striking feature of Lathraea squamaria<\/em> is that it lacks chlorophyll<\/strong>.<\/p>\n\n\n\n

    \n
  • Appearance:<\/strong> It has a characteristic pinkish, off-white, or slightly purple color. Since it does not photosynthesize, it has no green parts.<\/li>\n\n\n\n
  • Leaves:<\/strong> Its leaves have been reduced to small, fleshy scales<\/strong> (hence the name “squamaria” from the Latin squama<\/em> = scale), which cover the underground stem.<\/li>\n\n\n\n
  • Flowers:<\/strong> They appear in spring (March – May) in upright inflorescences that droop slightly to one side.<\/li>\n<\/ul>\n\n\n\n

    2. Parasitic Lifestyle<\/strong><\/h3>\n\n\n\n

    The Toothwort is a holoparasite<\/strong>. This means it depends entirely on the host plant for its survival.<\/p>\n\n\n\n

      \n
    • Hosts:<\/strong> It parasitizes mainly the roots of deciduous trees, such as Hazel (Corylus)<\/strong>, Alder (Alnus)<\/strong>, and Beech (Fagus)<\/strong>.<\/li>\n\n\n\n
    • Mechanism:<\/strong> It possesses specialized roots called haustoria<\/strong>, which penetrate the host’s roots to absorb water and nutrients (sugars).<\/li>\n\n\n\n
    • Underground Life:<\/strong> Most of its life cycle takes place underground. It emerges on the surface for only a few weeks a year, exclusively to bloom and reproduce.<\/li>\n<\/ul>\n\n\n\n

      3. Habitat<\/strong><\/h3>\n\n\n\n

      You can find it in:<\/p>\n\n\n\n

        \n
      • Shady, damp deciduous forests.<\/li>\n\n\n\n
      • Near ravines or riverbanks where its hosts thrive.<\/li>\n\n\n\n
      • Rich, humus-heavy soils.<\/li>\n<\/ul>\n\n\n\n

        4. Interesting Facts<\/strong><\/h3>\n\n\n\n
          \n
        • Longevity:<\/strong> The underground rhizome can live for several decades and spread extensively under the soil, sometimes weighing several kilograms.<\/li>\n\n\n\n
        • Etymology:<\/strong> The name Lathraea<\/em> is derived from the Greek word “lathraios”<\/strong> (hidden\/secret), precisely because the plant remains hidden underground for most of the year.<\/li>\n<\/ul>\n\n\n\n

          While there was an older theory that the cavities in the plant’s scales trapped insects (making it a carnivorous plant), we now know that these primarily serve to excrete excess water.<\/p>\n\n\n\n
