The _Pilumna nobilis_ is an evergreen Orchid, and is furnished with dark shining pseudobulbs four to six inches or sometimes more in height, and dark green leaves about six inches in length. The flowers proceed from the base of the pseudobulbs, three to four together in a loose raceme, and are of a pure milk-white, with a pair of clear orange-coloured spots, which impart a peculiar brightness to the throat; these flowers, which are very fragrant, are produced during the autumn months, and each lasts about two weeks in perfection. We find the plants to thrive when grown in pots or baskets, with rough, fibrous peat and good drainage. They need a moderate amount of moisture during the period of growth, but when at rest less may be given, merely enough to keep the bulbs in a plump state. They will thrive well in the Odontoglossum house. Lælia anceps.—We were very much surprised when calling on R. P. Percival, Esq., of Southport, to see the well-grown specimens of _Lælia anceps_ to be met with in his admirable collection of Orchids. On the side stage of one house there were 230 spikes of this charming Lælia just ready to burst their flower buds, some being open, and presenting to view their fine richly-coloured lips, and their rose-coloured sepals and petals. Some of the spikes, too, bore as many as four full-sized flowers. This group must have formed a most gorgeous sight during the dull time of year, namely, during November and December. Some of these plants, moreover, were producing as many as thirteen spikes, others a lesser number. This species is, as it deserves to be, a great favourite with Mr. Percival. There was among them a fine specimen of _L. anceps Percivaliana_, a most beautiful form, producing fourteen spikes of its chaste flowers, the sepals and petals of which are blush-white and the lip rosy purple. There were many other fine Orchids to be seen here. We must congratulate Mr. Percival on being so successful with his Cattleyas, which, when in bloom, must have been a grand sight, especially the varieties of _C. Trianæ_, _C. Mendelii_, and _C. Mossiæ_, which, between them, were producing many hundreds of flower-sheaths. Of _C. Percivaliana_ there were five plants throwing up their spikes, and they looked very promising and distinct; doubtless, as in the case of other types of Cattleyas, there will be many forms of this new species.—B. S. W. [Since the above was written Mr. Percival has exhibited one of these plants at South Kensington, and obtained for it a First Class Certificate. The flowers are not so large as in _C. Mossiæ_, but the lip is very richly coloured—a velvety crimson-purple with a border of pale rosy purple.] [Illustration: PL. 129. ONCIDIUM LANCEANUM LOUVREXIANUM.] ONCIDIUM LANCEANUM LOUVREXIANUM.
