Odontoglossum Williamsianum is an evergreen species, with pseudobulbs about 
three inches high, bearing at the top a pair of leaves about ten inches in height; 
the spike proceeds from the side of the bulbs, and bears as many as twelve flowers, 
The sepals and petals are of a greenish yellow, with distinct brown transverse bars; 
the petals are yellow, having a large pale brown anteriorly-lobed blotch at the 
base; and the lip is pale lemon-yellow, with a few pale dull reddish brown spots 
at the base. It continues in bloom for about four weeks. : 
This plant is now in the possession of the Comte de Germiny, Gonville, — 
France. It is the only plant we have seen. Professor Reichenbach thinks it is a 7 
natural hybrid between the two fine species referred to above, namely, Odontoglossum | 
grande and O. Schlieperranwn. 4 
This is a free-growing, as well as a free-blooming, plant. We grew it ma 7 
pot, with rough fibrous peat and good drainage, in the cool Odontoglossum _ house, a 
on a shelf near the glass, where it received plenty of light, but was quite shaded 
from the burning sun. It must also be kept moderately moist, but not so moist 
as Odontoglossum Alexandre. The same general treatment as suits O. grande is 
applicable to this fine novelty. . |

Taz Navioyat Inpusteiat axp Horricunrura, Exurerrron at Roven.—We had 
great pleasure in paying a visit to this exhibition in August last. It was one of great 
interest throughout, though our chief object was to see the floral part of it. The “7 
grounds were tastefully laid out, and well planted with ornamental trees and shrubs, 
including Palms and other foliage plants; also many beds of flowering plants, the - 
whole surface well diversified and undulated, intersected with broad walks, and set of 
with grass lawns. There was a grand piece of water with many interesting 
aquatic plants in full bloom, and having a well-arranged fountain in the centre - 
The building all around contained a magnificent exhibition, in which were all kinds 
of machinery and various products manufactured in France and her Colonies. Our — 
object is to deseribe a grand lot of Orchids exhibited by the Comte de Germiny, 
Chateau de Gouville, near Rouen, France. This collection was placed in a Spar 
roofed house 70 feet long, and 20 wide, which was kept filled with foliage plants, = 
Orchids, and other flowering plants, the whole time the exhibition was opel, all 
maintained at the Comte’s own expense, which was a oreat undertaking for one 
gentleman to keep going for so long a time. When we were there in the month 
of August it was a grand sight, there being many wonderful specimen Orchids, een 
of the best of which we will describe. An enormous specimen of Cattleya rn 
four feet in diameter, bearing 125 flowers, a gorgeous sight. Sobralia aantholewct, — 
a most rare and remarkable specimen, with many flowers of a creamy JY ellow, 3 
the lip lemon-yellow, and the throat orange colour, a most distinct spect “4 
Epidendrum prismatocarpum with twelve fine spikes. On either side of the path 2 
were two magnificent plants of Cattleya gigas, with their large showy flow : i 
C. labiata pallida had over twenty spikes of flowers and buds; it was in _
