long. It is of deciduous habit, losing its leave* annually, previous to (lowering. The (lowers arc produced 

 in threes, on opposite Hides of the stem, and each flower measures upwards of four inches across. The 

 sepals and i>ctak arc white, lipped with rich magenta; the lip also is white, tipped with magenta, iU lower 

 l>art of a deep orangc-ycllow, marked on each side with patches of crimson. The flowers arc produced in 



April and May, and last for several weeks. 



According to our own experience and that of the other growers who possess it, this is a free-growing species. 

 Mr. Bay's plant is making its fresh growth own finer than before; and his gardener, Mr- Stone, is of 

 opinion, as the growth is earlier, that he will be able to ripen (he bulbs much better, and thus cause the 

 plants to produce a still greater abundauce of flowers. In this wc have no doubt ho is correct : indeed, this 

 is the only way to secure a vigorous and abundant bloom. 



There is no genus of Orchids that will repay the attentions of the cultivator better than Dmdrobimn, 

 and we very much regret to sec the many splendid plants composing it so much neglected. There are, in fact, 

 when they are well grown and well flowered, none to equal them for warm conservatory decoration, in the 

 winter and spring months; and there are no Orchids more accommodating, nor any that produce such 

 quantities of flowers. Many of them, again, are not at all expensive. They arc, besides, of cjisy propagation, 

 producing freely from the old stems young plants, which only require to be taken off and potted. The 

 greater |>art of them divide well just as they commence growing. "We strongly recommend those who aim 

 at having their Orchid-houses gay to grow Dendrohium Mobile and its varieties freely ; it may be had in 

 bloom from Christmas to June merely by keeping a succession of plants, and starting them at different 

 periods. The course of treatment should be this:— After they have made their growth in autumn, place 

 those required latest in a greenhouse, and keep them rather dry; then, when they are required for blooming, 

 remove them into beat. The plants will thrive in any warm house in summer, but the bulbs must be well 

 ripened to cause them to produce and perfect a profusion of bloom. 



This DeNdrobiitm Wardiaaum* being a species of pendent growth, will be belter grown in baskets or 

 on blocks than in ]>ots. "We cannot do better than explain the course of treatment adopted by Mr. Stone. 

 The plant is on a block of wood, on which it seems to root freely, the roots hanging from the block some 

 two feet in length. It is grown, suspended from the roof, in the Caltlcya-housc, where the heat is not over 

 GO or Gu e in winter, though in summer the temperature is higher. In the growing-season it has a liberal 

 supply of water at tbc roots. Growing thus on a block of wood, the plant requires more water than under 

 other treatment; indeed, a little moss over the root would be of great advantage, as they would then be 

 kept more regularly moist* and in summer, without some such precaution, the blocks dry very quickly. If 

 the plants are allowed to get too dry it causes the stems 10 shrivel, and this injures the young growth : in 

 fact, under such circumstances, it is arrested for u season. The plants will also do well in a basket, with 

 sphagnum-moss and broken potsherds, the baskel being suspended from the w>of. tn Lhu way they do not 

 require so much water as when on blocks. 



The Dendrobcs are subject to the attacks of several kinds of insects, such as ml spider, thripe, etc. 

 Such pests should be kept away by frequently washing the leaves. The plant now immediately under notice 

 is not so readily propagated its many of the other species, as it does not produce young shoots so freely on 

 the old steins. When they arc produced, they should be taken off, and put upon blocks, with a little 

 sphagnum-moss.
