Meadow-Saffron (Colchicum autumnale).
The Meadow-Saffron is more frequently known as the Autumnal Crocus, but we object to the name as conveying a wrong idea of the botanical characters of two distinct genera. Further, there is a true autumnal crocus (Crocus nudiflorus), though its claim to be considered British is open to doubt. Like Crocus, Meadow-Saffron has an underground solid stem (corm), resembling a bulb, and from this arise the flowers in succession from August to October. These flowers are of a pale purplish colour, and consist of a long slender tubular perianth, enlarging at its upper part into a bell-shape, and this portion is divided into six segments, to each of which a stamen is attached (Crocus has but three). The ovary lies deep within the calyx-tube, and from it arise three long thread-like styles, which are bent over near the tip, the inner side of which is the stigma.
The fruit develops during the winter, and by the spring is ripe. Then when the long, flat leaves make their appearance, the flower-stalk lengthens and brings the ripe capsule above the ground. Sometimes the flowers mistake the seasons and put in an appearance with the leaves in spring, but they are imperfect, and the perianth is greenish-white.
The name is from Colchis, where it is said to have grown abundantly.
Hart’s-tongue Fern (Scolopendrium vulgare).
Hitherto we have dealt only with flowering plants. In these sexual organs are borne in more or less conspicuous blossoms, and, as the result of fertilization of the ovules by the pollen, seeds are produced which give rise to plants exactly like that which bore them. Ferns produce an enormous number of minute bodies, called spores, which are incapable of developing directly into a plant similar to that by which they were produced; but on germination they give rise to a minute green scale, like a liverwort, upon the under surface of which sexual organs appear, and by the mingling of their cell-contents a true bud is formed, from which a true fern-plant is evolved. There are other important points upon which ferns differ from flowering plants, but it is not within the author’s province to deal with them here. Let it suffice to add that as a fruit-bearing organ the leafy portion of a fern differs greatly from the leaves of other plants. To prevent confusion it is termed a frond.
The Hart’s-tongue has a frond of very simple character—strap-shaped—consisting of a stout mid-rib (rachis), with a leathery green expansion on either side, the upper end tapering off to a point, the lower divided into two lobes. A large number of thick red-brown parallel ridges on the under surface will attract immediate attention. These are heaps of delicate capsules (sporangia), which contain the spores. The Hart’s-tongue is a plant of sandy or rocky hedgerows.
