Grey Alder

Flower: Grey Alder produces unisexual catkins—the male catkins are long, pendulous, and yellowish-green, appearing before or with the leaves in early spring, while the female catkins are smaller, upright, and initially green, later turning brown as they mature. The flowers lack petals and rely on wind polli... Fruit: The female catkins mature into small, woody, cone-like structures called strobiles, about 2–3 cm long, which open to release tiny winged seeds in late autumn or winter. These “cones” persist on the tree through winter. Leaves: The leaves are oval to lance-shaped, with a rounded or slightly heart-shaped base, and have a finely serrated margin. They are a pale green above and lighter below, often with fine hairs on the underside.

Bog Arum

Flower: Bog Arum produces a striking, arum-like inflorescence consisting of a creamy-white spathe that wraps around a short, yellow-green spadix. The spathe is around 4–6 cm long, and the flowering period typically occurs in late spring to early summer (May to July). The spadix is covered with tiny, bisexua... Fruit: The plant develops a cluster of bright red berries in late summer. These are fleshy, rounded, and contain several seeds. While visually attractive, the berries are toxic if ingested, containing irritating compounds that can cause severe gastrointestinal symptoms. Leaves: Bog Arum has glossy, dark green, heart- or kidney-shaped leaves with long stalks, often growing up to 15 cm long. They emerge from a creeping rhizome and often form a loose rosette. The leaves are thick and waxy, helping them survive in their typical waterlogged habitats.

Awlwort

Flower: Awlwort bears tiny, white, four-petalled flowers that are typical of the cabbage family (Brassicaceae). Each flower is about 2–4 mm across, often inconspicuous and held just above the water or even submerged. Flowering typically occurs from June to August, and the delicate flowers may go unnoticed u... Fruit: The fruits are small cylindrical capsules, around 5–10 mm long, that develop from the flowers and contain numerous minute seeds. As is typical in the Brassicaceae family, these seedpods (siliques) dry and split open to release seeds that are easily dispersed by water movement. Leaves: Leaves are slender, awl-shaped (narrow and tapering to a fine point), which gives the plant its name. They are bright green, soft, and typically grow in rosettes at the base, submerged or floating just under the water surface. Each leaf is 2–6 cm long and lacks a distinct stalk (sessile). The plant ...

Alpine Bartsia

Flower: Alpine Bartsia produces striking dark purple to violet flowers, about 15–20 mm long, arranged in dense terminal spikes. Each flower is two-lipped, with a hooded upper lip and a three-lobed lower lip, typical of the figwort family (Orobanchaceae). The flowers appear from June to August, providing a b... Fruit: After flowering, the plant develops small, oblong capsules, each containing numerous tiny seeds. These capsules remain enclosed by the persistent calyx. Seeds are dispersed by wind and gravity, often falling near the parent plant — contributing to its patchy and restricted distribution in upland hab... Leaves: Leaves are opposite, dark green to purplish, and coarsely toothed, with a slightly glossy surface. They are ovate to lance-shaped and often have a reddish tinge, especially in upland light conditions. The lower leaves are stalked, while upper ones are often sessile (without stalks) and can sometimes...

White Beak-sedge

Flower: White Beak-sedge (Rhynchospora alba) features small, inconspicuous flowers with pale to creamy-colored petals, typically arranged in compact clusters or spikelets at the tips of its slender, grass-like stems. The flowers are delicate and often go unnoticed due to their subtle appearance, but they ad... Fruit: The fruit of White Beak-sedge consists of small, nut-like achenes. These achenes are typically dark brown or black and are attached to the plant's stem in clusters. They have a hard, seed-like shell and are dispersed by wind or water, contributing to the plant's reproductive cycle. Leaves: The leaves of White Beak-sedge are long, slender, and grass-like in appearance. They are typically dark green and have a linear shape. These leaves grow in dense tufts and arise from the base of the plant, forming an attractive clump. The leaves are typically smooth and narrow, adding to the overall...

Brown Beak-sedge

Flower: Rhynchospora fusca, or Brown Beak-sedge, flowers from June to August and has a distinctive appearance compared to most Carex sedges. Belonging to the related genus Rhynchospora, it features small, inconspicuous spikelets arranged in a few loose clusters near the top of wiry stems. The spikelets are ... Fruit: The fruit is a small, hard nutlet (achene) crowned with 6 fine, bristle-like teeth forming a tiny "beak" — a key ID feature of the Rhynchospora genus. In R. fusca, the achene is dark brown with a smooth surface, and the beak (or tubercle) is distinctly separated from the body of the nutlet. Fruiting... Leaves: Leaves are narrow, stiff, and wiry, typically 1–2 mm wide, and mostly basal — often giving the plant a sparse appearance. They are green to brownish-green and have a smooth to slightly rough margin. The stems are wiry, 15–40 cm tall, and three-angled in cross-section. The overall growth is more scat...

Arctic Bearberry

Flower: Small white, bell-shaped flowers. Flowers are stalked. 5 green sepals and 5 fused petals.. 10 stamens. Pollinated by bees. Fruit: The fruit is a globular black berry, up to 12mm in diameter. Fruits are green initially, later turning red and then finally black. Leaves: Small oval, pointed leaves with finely toothed margins.

Slender Marsh Bedstraw

Flower: Flowers appear in small clusters. The flowers are pale pink on the outside and creamy-white inside. Flowers each measure 2 or 3mm across. Fruit: The fruit is a high domed, warted nutlet. Leaves: The linear leaves are in whorls of 4 to 6 along the stems. The tips of the leaves can be either blunt or pointed. Similar in appearance to Fen Bedstraw (Galium uliginosum) and Marsh Bedstraw (Galium palustre) except Slender Marsh Bedstraw is more slender and weaker branched. It is also a shorter gro...

Marsh Bedstraw

Flower: Marsh Bedstraw produces small, star-like white flowers from June to September. Each flower has four narrow petals arranged in a cross shape, giving a delicate, open appearance. The flowers grow in loose, branched clusters at the tips of stems and leaf axils. Though individually tiny—only 2–3 mm acro... Fruit: The fruit consists of a pair of tiny round nutlets, each with a rough surface and covered in hooked bristles that help them cling to passing animals or float in water. These ripen in late summer and autumn. This method of dispersal aids the plant’s spread through marshes, ditches, and boggy areas. Leaves: Leaves are narrow, lance-shaped, and arranged in whorls of four to six around the stem. They are smooth-edged, with a slightly glossy green surface, and lack the backward-pointing hooks seen in some other Galium species. The stems are weak and square in cross-section, often sprawling or scrambling o...

Velvet Bent

Flower: Agrostis canina produces fine, delicate flower heads in the form of a narrow, open panicle, usually 4–12 cm long. The tiny spikelets (each about 2 mm long) are one-flowered, and unlike some other Agrostis species, the florets may or may not have an awn (bristle). The overall effect is a light, feath... Fruit: The fruit is a minute, dry grain (caryopsis), like in most grasses. It is dispersed via wind or surface movement, though reproduction is often more successful by rhizomes and stolons, which allow the plant to form dense, spreading mats. Fruiting typically follows flowering in late summer. Leaves: Leaves are very fine, narrow, and soft-textured, usually flat or slightly rolled. The leaf blades are up to 10 cm long, with a smooth upper surface and often a silky sheen. The ligule is long and pointed (up to 5 mm)—a key ID feature. Unlike some bent grasses, A. canina spreads via stolons and rhizo...

Flower: Male and female catkins appear on the same tree. Erect female catkins are shorter and green. Male catkins hang loosely in groups of 2-4. Often hybridizes with Silver Birch making identification tricky. Fruit: Small dry one-sided winged fruits, called 'achenes'. Leaves: Deciduous. Ovate, pointed and with serrated margins. Light green in spring, darkening and then turning yellow or orange in autumn. Leaves are often hairy underneath.
