in flowering a very excelient variety of M. aromatica, of which the pseudo-bulbs and 
leaves a.re finer, and the flowers are considerably larger, besides being of a superb 
golden colour, with more markings of brown in the lip. 
Maxillaria citrina. In the habit and leaves this new species is something 
like M. stapelioides, and the flowers are also produced solitarily, on short peduncles. 
The blossoms are, however, of a yellow colour, with a very few spots in the middle, 
and the lip is difl'erently formed. It is a pretty little species, and is blossoming 
with Messrs. Loddiges. 
Oncidium longifolium. Allied to 0. Ceholleti, from which it difi'ers in being 
far stronger in all its parts. The leaves, which are unusually lengthened, have a 
curious habit of partially twisting themselves and turning downwards, when they 
arrive at a certain age. The flower-stem is very luxuriant and spotted, and the 
flowers are copious, yellow, blotched with brown ; the lip and appendages being 
entirely yellow, save a little brown near the base. It flowered, six weeks back, in 
Messrs. Loddiges' orchidaceous-house. ■

Most of the flower beds and borders being now thoroughly filled, and all tender 
exotics that had been prepared for the open ground transferred to their proper position, 
it is to be desired that a vigorous growth may forthwith commence. To promote 
this, unless the season be more than usually wet, frequent waterings will be 
requisite ; and as all other plants may be said to demand the greatest quantity of 
water during the present month, a few remarks on the practice of watering will 
not be misplaced. 
One of the first principles to be observed in the application of water, is not to 
flood the ground on which it is poured, nor to supply it so rapidly, or so copiously, 
as to create pools or puddles on the surface of the earth. The immediate efi'ect of 
any such process may be witnessed in the case of heavy rains. When the water 
descends with a violence and precipitancy sufficient to occasion a general pool on 
the face of the soil, it invariably follows that, if a hot sun ensue, the surface is 
hardened into a concrete crust, which must be disturbed and broken before it will 
again become pervious to moisture. In the case of artificial watering, precisely 
similar results attend an equally abundant irrigation. Hence, it is to be recom- 
mended that, where practicable, each plant should be watered individually from 
the spout of a pot, and no rose employed except in the case of seed-.beds. 
Plants in pots are particularly liable to be affected by receiving their water 
through a rose, especially if they have to be much exposed to solar influence. We 
have before us some specimens that have almost perished from being watered, 
directly after potting, through a coarse rose. The top of the soil at once became a
