Goblets & envelopes

I was happy to see my first flowering Winter Aconite this weekend on National Cycle Network Route 77 outside Pitlochry. This little yellow winter plant is described beautifully on one webpage...the flowers are "contained within a circular envelope" of "minutely-pointed" leaves. The petals "at first form a ball, later a goblet". A lovely description for a lovely wildflower, reassuring us that Spring is coming.
