FLORTICULTURAL NOTICES. 
is particularly flattened. From the two specimens above alluded to, the careful 
observer may readily learn the degree of temperature most congenial to this plant. 
That at the Hackney nursery has evidently been subjected to a too great heat, the 
branches, and all the other parts, being extremely weak, and preternaturally 
elongated. The plant at Tooting is, on the contrary, in a very vigorous condition, 
but it is plain that even the present mild autumn is not warm enough to occasion 
the full development of its flowers. A greenhouse, therefore, suggests itself, as the 
fittest situation, while it should either be trained to the pillars, (if there be any,) 
or kept in a large pot, and supported by a circular trellis ; because, if fastened to 
the roof, it would exclude the light too much in the dark declining months of 
the year. 
Oncidium hJans. This is a very neat little species, which we have yet seen in 
the collection of Messrs. RoUison only, with whom it blossomed last month. It assi- 
milates slightly to 0. Harrisonianum^ having small, numerous, somewhat flattened, 
two-edged, and pale green pseudo-bulbs, surmounted by either one or two leaves ; 
(generally only one ;) but the foliage is most abundantly dotted with little white 
spots, and is likewise more coriaceous. The flowers are of the common brown 
and yellow colour, and are produced on short erect scapes : they are neither large 
nor brilliant, but interesting. 
PrImula sinensis ; mr. plena. Messrs. Henderson, 'of Pine-Apple Place, 
possess two charming varieties of P. sinensis, with fine double flowers. One, which 
has white or cream-coloured blossoms, is particularly valuable, combining all the 
beauty of the common double white primrose with the delicacy and grace of the 
Chinese species. The other has blossoms of a pink hue, and is only inferior with 
respect to the greater similarity in its colour to that of the single kinds. For 
decorating the windows of boudoirs, drawing-rooms, or other like situations, now 
that scarcely any other flowers are to be procured, nothing can be more^exquisitely 
appropriate. They must be increased by offsets,' and watered with great care. 
Saccolabium BipiDUM. To any other eyes than those of a botanist, or a close 
investigator of the forms and habits of Orchidacege, the plant, whose name we have 
here given, would appear to be a species of Notylia ; the manner in which the 
flowers are produced, their structure, and exceeding minuteness, being, so far as a 
hasty glance can determine, in complete accordance with the members of that genus. 
The moment,^however, that the mode of growth is examined, the delusion vanishes, 
and it is discovered to have terete stems (instead of pseudo-bulbs) and opposite 
leaves. Its small and almost imperceptible flowers are barely interesting enough to 
render it at all desirable, but they have a curious fork at the extremity of the 
peculiarly long lip, which stamps them with at least a unique character. It has 
lately bloomed for several months in the orchidaceous house of Messrs. Loddiges; 
and to those who make this tribe their study, nothing can be more useful than to 
search for the more palpable portions of a generic distinction among tiny plants 
like the present.
