" This is very unlike any other Asiatic species of Buddleia in its size and form of flower, color, and the locality it inhabits, its congeners being almost without exception tropical or subtropical plants ; in several respects it more closely resembles some of the species of the Andes, but it has no rival anywhere for beauty and graceful habit. It is abundant towards the summit of Tonglo, from 9000 feet to the top 12,000 feet This will probably prove perfectly hardy, as I have found it in very exposed places as well as in woods ; and from the abundance of its flowers, and its lasting some weeks in bloom, it would be a most desirable addition to our gardens." Let us add that the flowers are as fine as those of Escallonia macrantha, and as deep a red, while they grow in panicles as large as that of a common Lilac.
AEschynanthus Peeli, found in the thick forests where there has been no clearance, is perhaps a more brilliant red plant than any of the gorgeous species previously met with.
To these have to be added a Rhubarb (Rheum nobile)* of most prodigious form, resembling a giantess flounced from head to foot; an Oak (Quercus lamellosa) with magnificent leaves, comparable to those of the Spanish Chestnut, rendered hard and evergreen, and acorns so woody as to render riding unsafe where they have fallen in large quantities ; the Sikkim Larch now in our gardens, which appears to be tender only when raised from seeds gathered at 8000 feet of elevation, but to be hardy if produced by seeds from 13,000 feet; and Vanda Cathcarti, a fine epiphyte, with great fleshy flowers, streaked with cinnamon-colored bars. Such things as these point unmistakeably to the scene of a new collector's labors ; and it is to be hoped that the East India Company will forthwith despatch a skilful person in search of them. - Gardeners' Chronicle.
