The Short-Leaved Gentian
(GENTIANA BRACHYPHYLLA)
A particularly fine group of this beautiful little Gentian is here photographed. It is typical of the high Alps or snow region, and is rarely found below 6000 feet, and while scarce above 9000 is to be gathered even at 12,000 feet on the Matterhorn. But a single flower is borne by each little plant at the top of a short stem, which also bears the small, thick, closely packed leaves. The plant is found growing in the turf of mountain pastures and rocky places in the central parts of the whole Alpine chain. It is moderately common particularly on primary rock, and is also met with in Dauphiny and the Pyrenees.
Of the twenty or more species of Gentian that occur in Switzerland, some are tall, stately plants, bearing numerous blue, yellow, or purple flowers. Others are much smaller and bear relatively few flowers, or even one only in small feeble plants. A few never have more than a single blossom to each little plant. Among these last are the Stemless Gentian with its bell-shaped flower, figured on the previous plate, and the Short-leaved Gentian with its star-like flower, which we here illustrate. As a matter of fact, there are really three single-flowered Star-Gentians and to distinguish between them is not easy. Of these the Bavarian Gentian (Gentiana bavarica) is recognised from our plant by its longer stem, perhaps 2 to 3 inches long, on which only two or three pairs of opposite leaves are borne, and by the fact that the lower leaves are smaller than the upper. The Spring Gentian (Gentiana verna) has a very short stem, covered by closely packed leaves like the short-leaved variety, and like it, too, the lower leaves are the larger, but its leaves are harder, narrower, and more pointed, and short wing-like projections are found on its calyx.

The Alpine Toad-Flax
(LINARIA ALPINA)
This beautiful little plant is abundant in all parts of the Alps. It is one of the first to take possession of fresh soil, but disappears rapidly under the stress of competition with other plants. Its numerous winged seeds are carried far and wide by the wind, and take root and grow rapidly on any open space. Hence it is found among the general rocky débris of the mountain-side, on the moraines of glaciers, and on the fresh soil brought down by avalanches, and is most abundant in limestone districts. Its true home is the high Alps and the snow region, and it flourishes best between 5000 and 9000 feet; but it is often carried down to a much lower level by the rivers, and is even found locally in the plains of Southern Germany. The Alpine Toad-flax is an inhabitant of most of the mountain ranges of Central and Southern Europe, and is thought to have taken origin in the South. It flowers from June till September, and seems to have derived its name from its flax-like foliage.
