Sansbury, Is-y-coed, Talybont, Cards.] BOTANICAL The following notes on the St. David's peninsula of Pembroke- shire are contributed by Mrs. M. BARNES. The St. David's peninsula with its maritime climate, situated almost in the centre of the Pembrokeshire National Park, is an ideal spot for the plant hunter, as the choice of habitats, such as moorland, stream, coastline and rock outcrop appeal to the specialist or tyro. The lichen and moss covered walls in the city present a mosaic appearance, and embedded in the masonry is the dainty fern, Maidenhair Spleenwort (Asplenium trichomanes), Polypody (Polypod- ium vulgare), English stonecrop (Sedum anglicum), Pennywort (Umbili- cus rupestris), and Vervain (Verbena officinalis) with its pale lilac spikes of bloom. Wandering away from the City, upstream, alongside the Alan, a conglomeration of plants struggling for ascendancy meets the eye. Great Water Dock (Rumex hydrolapathum) is conspicuous amongst Yellow Flag (Iris pseudacorus), Purple loosestrife (Lythrum salicaria) and Meadow Sweet (Filipendula ulmaria). The hedges in this district are covered from early Spring by a profusion of colour, from the deep blue of Sheep's Bit (Jasione montana), Thyme (Thymus serpyllum agg.), Hairy Tare (Vicia hirsuta), Red campion (Melandrium dioicum), Agrimony (Agrimonia eupatonia), to the heliotrope pincushions of Field Scabions (knautia arvensis). Predominant on the hedge tops are Burnet Rose (Rosa spinosissima), and Honeysuckle (Lonicera perciclymenum), an exceptional display of the latter can be seen on the cliff-sides at Porth Glais. On the sand dunes towards Whitesands Bay, cowslips (Primula veris), linger to welcome the Spring Squills (Scilla verna), Bluebells (Eudymion non-scripta), and Thrift (Armeria maritima). But we must journey to the coastline around St. Non's Bay to appreciate the beauty of banks of Thrift against a back-cloth of blue sky and sea.
