callus yellowish white, consisting of fifteen nearly contiguous 

 lamellfe. The boat-shaped column is of a fine deep violet 

 blue, except the base, which is yellow. This will form a fine 

 distinct exhibition plant. It flowers in June and July, and 

 will last a long time in perfection. — Colombia.

B. Lalindei, Rchb.f. — A very distinct plant of recent intro- 

 duction. The leaves are elliptic lanceolate, narrowing to 

 the base, five-nerved, a foot long, distichous ; the scapes 

 are solitary ; the flowers are about three inches across, the 

 sepals and petals in plants flowered by us lilac at the base, 

 pale rose in the upper part, with the tips straw-colour, and 

 the lip golden yellow, with about thirteen close-set lamellfe ; 

 but in those described by Professor Reichenbach they were of 

 a bright violet, the upper sepal tipped with green, the lower 

 halves of the lateral sepals brownish purple, the lip deep 

 orange, and the column deep purplish. The column is very 

 peculiar, being broader than the lamellate disk, arched and 

 rose-coloured. — New Grenada.

B. Lawrenceana, Rchh. /. — a beautiful and delicately- 

 coloured species, resembling B. ccelestis in growth. The 

 plant is dwarf, almost stemless, with distichous broadly 

 ligulate acuminate leaves more or less keeled ; and axillary 

 scapes, each supporting a solitary flower, which measures 

 three and a half to four inches across, white distinctly blotched 

 with violet or mauve at the tips of both the sepals and the 

 petals, the white being contmued outside the blotch so as to 

 form a narrow margin. The lip is much shorter than the other 

 parts, squarish with the sides revolute, the apex of an intense 

 rich velvety purple, the basal callus large, bright yellow, 

 white on each side. The broad hooded white column is also 

 a conspicuous object in the centre of the flower. — Colomhia.

B, Patinii, Rchb. f. — A fine and distinct plant, having some 

 resemblance to B. Lalindei, but with larger flowers less 

 brightly coloured. The leaves, which are distichous, are 

 nervose, broadly oblong -ligulate, narrow at the base, 'and 

 acute at the apex. The scapes spring from the leaf-axils, 

 and are decurved, each bearing a solitary flower upwards of 

 three inches across ; the dorsal sepal and the obtuse petals, all
