I have been looking at this tree going to and from from Hay for 15 years. Stopped to ID and it seems to be a Western Balsam Poplar - new record for county. Obviously liked by Mistletoe (or the birds that distribute it).

The County New Year (BSBI) Plant Hunt. Joan found a flowering Viola reichenbachiana (Early Dog-violet) at Talybont on Usk - the first record for that south west corner of the hectad. It does flower early, but not usually that early. Trivia: What is the connection between this plant and Sherlock Holmes' famous falls where he fought Moriarty? Probably that the plant was first found in that area.
