Tendrils which have caught nothing simply bend downwards and inwards, like the extremities of the leaves of the Corydalis claviculata. But in all cases the petiole after a time is angularly and abruptly bent downwards like that of Eccremocarpus.
By this time the hepatica, anemone saxifrage, arbutus, houstonia, and bloodroot may be counted on. A week later, the claytonia or spring beauty, water-cress, violets, a low buttercup, vetch, corydalis, and potentilla appear. These comprise most of the April flowers, and may be found in great profusion in the Rock Creek and Piny Branch region.
But these sub-divisions graduate into each other, as we shall see under Corydalis and the Gloriosa lily. Palm and Mohl class these plants with those which bear tendrils; but as a leaf is generally a defined object, the present classification, though artificial, has at least some advantages. Leaf-climbers are, moreover, intermediate in many respects between twiners and tendril-bearers.
POLEMONIACEAE Cobaea scandens much branched and hooked tendrils, their manner of action LEGUMINOSAE COMPOSITAE SMILACEAE Smilax aspera, its inefficient tendrils FUMARIACEAE Corydalis claviculata, its state intermediate between that of a leaf-climber and a tendril-bearer. By tendrils I mean filamentary organs, sensitive to contact and used exclusively for climbing.
They climbed the hill where he came to battle with the stormwinds, and to watch the sunsets and the moon rising over the lake. And then they went down into the glen, where the mountain streamlet tumbled. Here had been wood-sorrel, and a carpet of the white trillium; and now there was adder's tongue, quaint and saucy, and columbine, and the pale dusty corydalis.
Articulate animals of the genus Scorpion were found by Count Sternberg in 1835 in the coal-measures of Bohemia, and about the same time in those of Coalbrook Dale by Mr. Prestwich, were also true insects, such as beetles of the family Curculionidae, a neuropterous insect of the genus Corydalis, and another related to the Phasmidae, have been found. Wing of a Grasshopper.
So with the flowers: the columbine, the shooting star, the painted cup, the puccoon, the beautiful though inodorous large white trillium, the delicate little corydalis, the star grass and the lady's slipper, all came within a week of their average time in spite of the cold, and the showy orchis was only just over into June.
The tip of one of these basal leaves, whilst young, described in 1 hr. 36 m. a narrow ellipse, open at one end, and exactly three inches in length; a second ellipse was broader, more irregular, and shorter, viz., only 2.5 inches in length, and was completed in 2 hrs. 2 m. From the analogy of Fumaria and Corydalis, I have no doubt that the internodes of Adlumia have the power of revolving.
The plant might have been left, one would have thought, to climb by the aid of its spines alone, like our brambles. As, however, it belongs to a genus, some of the species of which are furnished with much longer tendrils, we may suspect that it possesses these organs solely from being descended from progenitors more highly organized in this respect.
