Slender St John's-wort - Hypericum pulchrum
Short to tall, hairless, erect or ascending plant. Stems rounded, often reddish. Leaves opposite, heart-shaped, clasping the main stems, smaller and short stalked on lateral shoots, dotted with translucent glands. Flowers yellow with a red tinge (particularly underneath the petals), 14 or 15 mm in lax narrow panicles. Sepal margins with black glands, anthers orange to reddish pink.
Other St.John's-worts. See ID Aids below.
Stems not ridged; sepals more or less equal; leaves without black glands but black glands on sepals and petals.
The St John's Wort (Hypericum) family are attractive, yellow-flowered perennials. They can look confusingly similar but can be distinguished by careful examination of key features. A hand-lens may be required (depending how good your eyesight is!). The leaf perforations are visible as translucent dots if the leaf is held up to the light.
