plant IDs

In message , K writes Stewart Robert Hinsley writes My preferred references for identification at the moment are Garward and Streeter (illustrations and field marks) Is that the Collins one? No - coffee table size book published by Midsummer Press, bought from a remainder book shop. I couldn't find it on Google or Amazon and Sterry (photographs, field marks and portable, but lacking complete coverage). Sterry I've seen but didn't like, but not sure why Sterry is the (a?) Collins publication. It's generally well thought of, isn't it? Must be irrational prejudice on my part ;-) For photos, I've got some of the little books by Roger Philips, all sadly out of print now and very hard to come by. I'd forgotten I had a copy of Philip's Wild Flowers of Britain. It's in I haven't got that one. But he did a little series "mountain and moorland" "Roadsides and waste places" "weeds" "coastal" etc. The pictures are better than his big book. Like the big book, they're arranged in approximate order of flowering, which can be handy when you haven't a clue where to start. "Weeds" has pictures of the seedlings too - ideal for the gardener! I think I've just cracked the difference between Myosotis arvensis and Myosotis sylvatica Ah ... arvensis has smaller 'grey blue' flowers compared with larger 'sky blue' flowers. Arvensis flowers are slightly concave ("saucer shaped") whereas sylvatica are flat. Arvensis is usually annual, sylvatica is perennial. Sylvatica calyx is flightly flared at the top to reveal the nutlets. Situation slightly complicated by existence of garden forms of sylvatica and a shade subspecies of arvensis - is that about what you gleaned? which leaves the other terrestrial species around here as Myosotis ramosissima. Smaller flowers, flowering stem has very short leafy section and very long flowery section? My alternative to a hand lens is a macro photograph, but it doesn't always focus properly. I've got a 'supermacro' on my camera, but without flash. So I need good light for fast shutter speed. And the focusing is difficult if the flower is delicate - too easy to focus on the background not the flower. Piece of paper (or a hand) behind the flower can help, by bringing the background to the flower. Part of the knack is learning to see differences between plants and to use more traits than just the flowers. I know. I was browsing through the Stace key for Geranium and noticing that shining geranium, which is recognisable at 20 paces with or without flowers, doesn't key out until almost the end. And I irritate my husband by pointing out flowers to him and having to confess that actually, they're not in flower yet, it's just the leaves, but they *will* look beautiful in a couple of months time ;-) (Fruits are useful with trefoils and crucifers.) I had a great time in S Portugal earlier this year looking at legume seed pods. Some really strange ones. Another technique is learning field marks, which is why books with field marks are handy. What are field marks? -- Kay |
