And many ferns are just green or brownish but some ferns have astonishing white or even yellow fronds (a.k.a. "leaves"). The coloured lower frond sides are considered to be an adaptation to dry conditions. Many of these ferns have their sporangia (dark) on the margin, which creates a wonderful contrast. #FernFriday8 views Most people will know #ferns basically as green leafy things without flowers.

Old #herbarium sheets come with perks and challenges. I love to figure out what is written. For this particularly hard example, I got lucky because the collection was cited with the old species name in an old paper. It's "An der Lesum bei #Vegesack" in #Bremen, Germany. Could you have deciphered it? The label is written in German #Kurrentschrift, an old style of handwriting. The long s in "Lesum" The harmonious regularity of the inflorescence of this #Earina valida #orchid from #NewCaledonia is beautiful, even in a #herbarium specimen. The plant must look spectacular in nature. #HerbariumLife #CuratorLife Finding herbarium specimens in a large collection is not trivial. Specimens are stored under a scientific name, often called filed-as name, and arranged according to their higher taxonomy, i.e. families and orders. The filed-as name is preferably the correct name (under taxonomic rules and according to the latest taxonomic treatments). However, changes happen(ed) often and quickly, and it is impos This is a #grass‽ From giant bamboos to maize and the common lawn ryegrass, #Poaceae can be quite variable. #Panicum cupressifolium from #Madagascar has minute leaves, making it look like a #cypress (hence the name). #IAmABotanist #HerbariumLife #CuratorLife Sabbati even noticed that some plants are often found on walls, such as the red valerian (#Centranthus ruber).
