By way of carpeting, a broad edging of Selaginella surrounded the tank. This dwarf fern formed a thick moss-like sward of a tender green. And beyond the wide circular path, four enormous groups of exotic plants shot right up to the arched roof; the palms, slightly drooping in their gracefulness, spread out their fan-like leaves, displayed their rounded heads, hung down their branches like so many oars wearied by their eternal voyage in the azure of the air; the great bamboos from India ascended erect, slender and hard, with their fine shower of leaves falling from on high; a Ravenala, the traveller's tree, held up its bunch of immense Chinese screens; and, in a corner, a Banana tree loaded with fruit stretched out in all directions its long, horizontal leaves, on which two lovers might easily recline providing they kept pretty close to each other. In the corners were some Euphorbia from Abyssinia, those prickly, ill-shaped torch-thistles covered with horrid excrescences and reeking with poison. And the ground beneath the taller plants was carpeted by dwarf ferns, including the Adiantum and the Pteris, with fronds as delicate as the finest lace-work. A taller species, the Alsophilas, tapered upwards with their rows of symmetrical and sexangular foliage so regular that it had the appearance of enormous pieces of crockery intended to hold the fruits of some gigantic dessert. Then an edging of Begonias and Caladiums surrounded the beds; the Begonias with their twisted leaves superbly streaked with green and red; the Caladiums, the leaves of which, shaped like lance heads, white and veined with green, resemble the wings of some monstrous butterfly; bizarre plants which vegetate strangely with the sombre or palish glow of noisome flowers. Behind the beds a second path, a narrower one, went right round the conservatory. And there, on stages, half hiding the pipes of the heating apparatus, bloomed Marantas, as soft to the touch as velvet, Gloxinias, with their purple bell-shaped flowers, Dracænas, resembling blades of old lacquer. But one of the charms of this winter garden consisted in alcoves of verdure in the four corners, roomy arbours shut in by thick curtains of tropical creepers. Bits of virgin forests had weaved in these spots their walls of leaves, their impenetrable medley of stems, of supple shoots, clinging to the branches, traversing space by a bold leap, and hanging from the arched roof like the tassels of some rich drapery. A root of Vanilla, with its ripe pods exhaling a penetrating perfume, trailed about the arch of a moss-covered porch, whilst the Indian berry decked the little columns with its round leaves; Bauhinias, with their red bunches, and the Quisqualis, the flowers of which hung like necklets of glass beads, glided, twined and entangled themselves like slender snakes endlessly playing and stretching amidst the depths of the foliage.
