O'Brienianum from Epi. evectum × Epi. radicans; the former purple, the latter scarlet, produce ×a bright crimson progeny. Miltonias show two natural hybrids, and one artificial Mil. Bleuiana from Mil. vexillaria × Mil. Roezlii; both of these are commonly classed as Odontoglots, and I refer to them elsewhere under that title. M. Bleu and Messrs.
Epid. rhizophorum has been lately rechristened Epid. radicans a name which might be confined to the Mexican variety. For the plant recurs in Brazil, practically the same, but with a certain difference. The former grows on shrubs, a true epiphyte; the latter has its bottom roots in the soil, at foot of the tallest trees, and runs up to the very summit, perhaps a hundred and fifty feet.
On the other hand with Tecoma radicans, a member of a family abounding with twiners and tendril-bearers, but which climbs, like the ivy, by the aid of rootlets, we may suspect that a former habit of twining has been lost, for the stem exhibited slight irregular movements which could hardly be accounted for by changes in the action of the light.
T. radicans major is of more robust growth than the species, with larger foliage and paler flowers. The orange-scarlet flowers are produced in terminal corymbs. Lime, or Linden Tree. Europe, Caucasus, and naturalised in Britain.
It is, however, often substituted by the Rhus radicans, which has not the medical properties that this plant has; and it is to be regretted that the leaves of both species are so much alike, that, when gathered, they are not to be distinguished. RICINUS communis. PALMA CHRISTI. Seeds and Oil.
In the leaf-climbing Clematis flammula, and in the tendril-bearing Vine, we see no loss in the power of climbing, but only a remnant of the revolving power which is indispensable to all twiners, and is so common as well as so advantageous to most climbers. In Tecoma radicans, one of the Bignoniaceae, we see a last and doubtful trace of the power of revolving.
And lower down the great forest trees arch over it, and the sunbeams trickle through them, and dance in many a quiet pool, turning the far-down sands to gold, brightening majestic tree-ferns, and shining on the fragile polypodium tamariscinum which clings tremblingly to the branches of the graceful waringhan, on a beautiful lygodium which adorns the uncouth trunk of an artocarpus, on glossy ginger-worts and trailing yams, on climbers and epiphytes, and on gigantic lianas which, climbing to the tops of the tallest trees, descend in vast festoons, many of them with orange and scarlet flowers and fruitage, passing from tree to tree, and interlacing the forest with a living network, while selaginellas and lindsayas, and film ferns, and trichomanes radicans drape the rocks in feathery green, along with mosses scarcely distinguishable from ferns.
The flowers are very attractive, being of a rich orange-scarlet, and produced in drooping clusters. Both foliage and flowers are larger than those of T. radicans. It wants a warm, sunny wall, and light, rich, and well-drained soil, and if only for its lovely flowers, it is well worthy of coddling and good treatment. Trumpet Flower. North America, 1640.
If the repens is allowed to climb up high along the walls of the hothouses, it will at last produce stipulate branches with the corresponding fruits. Ficus radicans is another climbing form, corresponding to the shrub Ficus ulmifolia of our glasshouses.
Besides those common to England, the Pteris cretica grows luxuriantly in the damp ravines, as well as that most beautiful of European ferns, the Woodwardia radicans, whose fronds are often more than six feet long.
