DeNnpRoBIUM Amboinense. Hort. Rollison. 
This remarkable plant, one of the most singular of the many 
species of the genus Dendrobium known to us, was discovered 
by Mr. Henshall in Amboyna, and imported by Messrs. Rollison, 
of Tooting Nursery ; it flowered in the Orchideous stove in June 
of the present year (1856). When the plant shall have attained 
more health and vigour, there is reason to believe that the 
flowers will be more numerous and larger. We hasten to make 
known to other Orchid-growers so interesting a species. 
_ Dxscr. The leaf-bearing pseudobulbs are not more than three 
to four inches long, fusiform and angular, tapering at the base, 
the younger ones partially clothed with subfoliaceous scales ; the 
leaf itself terminal, solitary, oblong, acute, scarcely coriaceous, 
obscurely marked with parallel lines. In age, as it would ap- 
pear, these pseudobulbs lengthen, lose their leaf, and become 
naked, stem-like, and jointed, tetragonal below, bulbiform at the 
very base, four- to six-angled above: from this dry, stem-like 
‘ pseudobulb the flowers appear, in pairs, large, cream-white, soon 
: _ withering. Petals and sepals scarcely exhibiting any difference 
: in size or in shape, linear-lanceolate, at first spreading, ere long 
becoming flaccid and closing over the lip. Ladellum small, in 
proportion to the rest of the flower, concave, but scarcely spurred 
at the base below, three-lobed, lateral lobes broad, ovate, obtuse,
