appear to be an ally of the present one. BENTHAM, However HEE Grammangis 
as distinct, though he adds to it the Javan Cymbidium Efutiont Hook. F. (Bot. 
Mag., t. 5676), which appears to me not to possess the essential CEE A of 
Grammangis. As the present plant differs considerably from the Asiatic Gram- 
matophyllums, perhaps the best plan is to consider it as a distinct genus. 
It appears to be a very local plant in Madagascar, as M. SOLED is 
reported to have searched a long time for it, though he ultimately obtained 
a considerable number of specimens. The regular transverse bars shown on the 
sepals of the Botanical Magazine figure (copied in Flore des Serres) are probably 
incorrect, as in a coloured sketch by Dr. Linptey, preserved in his herbarium, 
not so represented.

the curse and ruin of the large majority of Orchid collections. Tobatco is an 
old insecticide, but it is not often applied as Monsieur Liven applies it. In 
every house, resting upon the hot-water pipes and held in position by means of 
wire netting, is a layer of the refuse stalks and midribs of tobacco leaves, which, 
in Belgium, can be obtained at about seven francs the hundred kilos. This is 
wetted once or twice a day, and the vapor which arises is consequently 
impregnated with nicotine, which permeates the whole atmosphere in the house 
and is inimical to insects. It does no harm to the most delicate plants, but it 
keeps down insects so well that Monsieur Linen finds it scarcely ever necessary 
to clean his plants. In this manner much labor is saved, and the plants are 
kept clean. Moreover, the injury which is the almost inevitable result of scraping 
and sponging the leaves of delicate Orchids, is altogether avoided. In England 
tobacco is too expensive to be used in this way, but it-would not be difficult 
to devise some means for obtaining the nicotine cheaply and in such a form 
as would satisfy the excise authorities. These are small details, perhaps, but 
upon them a great deal more depends than many growers imagine. 
There is a house with about five thousand magnificent plants of Angrae- 
cum sesquipedale, only a few months imported, but as healthy in foliage and 
vigorous in root-action as though they had been there for years. Then a huge 
houseful of Laelia purpurata, many of them grand specimens. A large batch 
of healthy plants of Saccolabium coeleste, one of the most beautiful of blue- 
flowered Orchids, was pointed out as * all that remained ” of a very large 
and successful importation of that very bad traveller; of Odontoglossum I saw 
some of the most beautiful species and varieties that it has ever been my 
privilege to see. Their names were legion, their value, in many cases, almost 
fabulous; about their exquisite beauty there could be no question. It was
