This is Alternate-leaved Golden Saxifrage, much less common than its relative Opposite-leaved Golden Saxifrage and one I've never been able to find up until now. Once seen though it is quite obviously different, especially in being larger and more brightly coloured with toothed leaves.
The yellow is very intense and the bracts glossy
Here it is with Opposite-leaved Golden Saxifrage (small flowers on left)
Alternate-leaved Golden Saxifrage - Chrysosplenium alternifolium
Purple Toothwort - Lathraea clandestina
Usually seen growing on the ground parasitising tree roots this clump was actually in the fork of a willow tree several feet above ground.
This is American Skunk Cabbage an invasive species which I believe is due to be eradicated from many areas. It is a very beautiful plant and looks spectacular but boy does it stink! It is probably one of the worst plants I've smelt (the worst is Hedge Woundwort - Hideous!!) The odour filled the whole woodland in the heat of the sun and made me feel quite nauseous. The smell made me want to leave but the visual delight made me want to stay.
With the light behind it you can see where it got its alternative name of Swamp Lantern
