Gentiana clausa

9-17-14 gentian closeup IMG_0088The pictured gentian in today’s post was Gentiana clausa, not G. andrewsii. These two species, both referred to as bottle gentian, are very similar, but there is one very distinctive difference. The flowers of both have 5 blue lobes forming petals that are fused together by a connecting fringe, creating folds between the outside of the petals. In G. clausa the petals remain closed at the tip with those fringes hidden by the closed tip. In G. andrewsii, the fringes of the flower lobes are longer than the petals and are visible at the tip of the closed flower. No visible fringes means today’s photograph is of Gentiana clausa. Thanks to Jon Binhammer for bringing this to my attention!

    I am amazed at what you see and know!
    Where might I observe an otter?

    • It’s hard to tell you where to look for an otter, Pat — they are often on the move, but obviously love ponds and wetlands. I usually discover their presence from their signs – scat, slides, tracks, etc. Much easier in winter! Mary

  2. Is the flower ‘sealed’ closed? How is it pollinated? Or can bees get in? I’m ‘naturally curious!’ 🙂
