Botany Report for 2009

by Gill Smith

Overview

2009 started cold and snowy, and spring was late with the main “greening“ not happening till the very end of April. The bluebells were at their best in the first week of May, perfect for the Ryenats’ Riccaldale outing.

I personally had a very exciting year botanically, seeing 7 species for the first time: lesser twayblade, basil thyme, yellow birdsnest, burnt-tip orchid, field garlic, Dutch rush, and the alien/introduced New Zealand buttonweed Cotula alpina; and some unusual ones: dodder, mountain everlasting, deadly nightshade in flower, yellow birdsnest, bee orchid, fragrant orchid (var. densiflora and marsh helleborine, as well as pure white forms of bell heather near Ana Cross above Lastingham and ragged robin in Seivedale Fen. I also confirmed an old record of lily-of-the-valley near Gilling, discovering quite a sizeable patch with several flower spikes.

I went on several plant-hunting walks, and some of the highlights are:
Gagea doing well in both Kirkdale and near Appleton-le-Moors.
Herb paris, twayblade, lily of the valley, early purple orchids, wood anemones in Beadale on 2nd May.
Seeing the locally rare and very elusive lesser twayblade at Darnholm on 17 May.
At Ashberry on 24th May: lily-of-the-valley, baneberry, columbine, herb paris, globeflower, birdseye primrose, early marsh orchid, meadow saxifrage (not doing particularly well).
Small toadflax Gilling old railway 13 June.
Butterfly orchids, deadly nightshade, burnt-tip orchid, fly orchids in limestone grassland and woods, Hutton Common and Yatts 14 Jun.
Yellow birdsnest, bee orchids, mountain everlasting and marsh orchids in old limestone quarry, damp grassland and fen, Sutherbruff and Sandale 21 June.
One clustered bellflower, 6+ knapweed broomrape Broughton 16 July. Bill reports broomrape at Swinton on 31st
Dodder, basil thyme and various insects in dry limestone grassland and scree / old quarry, Gundale 19 July.
Field garlic Swinton 20th July.
Fragrant orchid Gymnodenia conopsea subsp. densiflora and marsh helleborine Epipactis palustris in damp grassland and fen, Seivedale Fen 25 July.
