Part 32

The leaves of the Purple Loose-strife are dark green. Usually they are covered with fine hairs, but sometimes you find leaves which are quite smooth. It is easy to recognise this plant by the rings of flowers growing close round the main stem.

3. COMMON BUTTERWORT

It is always a delight to find the dainty Butterwort. It grows in heaths and bogs and marshes almost everywhere, but is most abundant in the North. The delicate flowers bloom in summer.

You will easily recognise this beautiful highland plant by the leaves. They are thick and juicy, and grow close to the ground in a pale green star-pointed rosette. Each leaf is stalkless and as smooth as satin. On the upper side these leaves are pale yellow-green, but sometimes the edges curl upwards, and then you see that the leaf underneath is so pale that it is almost white.

From the centre of the rosette rise tall, slender stalks with drooping flower-heads. These flowers are dark bluey-purple, and their petals are joined into a short tube which stands in a shallow, toothed calyx-cup.

The mouth of the tube folds back in two parts. The upper half is short, with a deep notch in the middle. The lower half is much longer, and is divided into three deep scollops.

You will find a pink horn-like spur standing up near the base of the short tube, and you can see that the back of the flower is a delicate rose pink colour. Inside the blue tube there are two stamens and a curiously shaped seed-vessel hidden from sight.

PLATE XXXVI: 1. COMMON BUGLE. 2. GROUND IVY. 3. HAIRY WATER MINT.

1. COMMON BUGLE

The Common Bugle is a low-growing plant, very frequently found in open woods, banks, and pastures. It blooms in spring and early summer.

You will not think this a very attractive plant. The leaves and flowers are crowded together from top to bottom of the main stem. The stem is pale purple, and has four sides. It is hollow in the centre, and breaks off easily because it is soft and juicy.

The flowers grow without stalks in circles close to the stem wherever the leaves join it, and each circle is close to the one above it.

In every flower there is a slender tube, and one half of this tube folds over at the mouth into three lips, the centre lip having a notch in the middle. The other half of the tube stands erect.

These flowers are usually deep blue, but you may find them purple, or rose colour, or even white. They are never yellow.

Four golden-headed stamens stand up a good way beyond the mouth of the flower; two of these are short and two are much longer. The forked tip of the seed-vessel can be seen among these stamens.

The end of each tube stands in a small green calyx-cup edged with pointed teeth.

The leaves of the Common Bugle are dark green, and each pair clasps the stem closely at the bottom.

2. GROUND IVY

The Ground Ivy bears little resemblance to the ivy we all know so well. It is common everywhere, and blooms in spring and early summer.

The flowers grow without stalks in whorls or circles close to the stem where the leaves spring from it. These flowers are dark purply-blue tubes, prettily divided at the mouth into rounded lips. The lower lips are marked with white and dark purple blotches. Inside the tubes are four small stamens with yellow heads; you can just see them at its mouth, with the forked tip of the seed-vessel among them.

There are usually six or more flowers in a whorl, and each flower has a green calyx-cup which is very hairy and is edged with five long sharp teeth.

From each side of the stem, close among the flowers, grow two leaves on pink stalks. These leaves are round and are beautifully scolloped at the edge. Each leaf is covered with a network of veins and is hairy all over, both above and below, as well as round the scollops.

These circles of leaves and flowers grow at intervals all the way up the stem, with a good distance between each circle, and the flowers in the lowest circles always come out first.

The stem of the Ground Ivy is four-sided. It is tinged with pink and is very hairy.

3. HAIRY WATER MINT

This strong-smelling plant is common everywhere. It likes to grow in wet places, and it is in flower towards the end of summer and in autumn.

The Water Mint is not an attractive plant. It has four-sided juicy green stems stained with purple. These stems do not grow straight.

The flowers grow in pink clover-shaped heads, either at the end of the main stem or sometimes on very short stalks which spring from between the stem and the leaf.
