Amboinense. Hort 



This remarkable plant, one of the most singular of the many species of the g^nus 

 Dend rohium , was discovered by Mr. Henshall in Amboyna, and imported by Messrs. 

 HolUson, of Tooting Nursery, where it flowered in the Orchideous stove in June, 1856. 

 Most unfortunately, the plant perished shortly after it was figured, and still awaits rc- 

 mtroduction. Few species would be more»welcome. 



Descr. The leaf-bearing pseudohulhs are not more than tln-ee to four inches long, 

 fusiform and angular, tapering at the base, the younger ones partially clothed with sub- 

 foliaceous scales; the leaf it^eli terminal, solitary, oblong, acute, scarcely coriaceous, 

 obscurely marked with parallel lines. In age, as it would appear, these pseudobulk 

 lengthen, lose their leaf, and become naked, stem-like, and jouited, tetragonal 

 bulbiform at the very base, four- to six-angled above: from this dry, stem-like pseud 

 bulb the /ow^r5 appear, in pairs, large, cream-white, soon withering. Fetals ^udscj)^ 

 scarcely exhibiting any difference in size or in shape, linear-lanceolate, at first spn-a

 lateral lobes broad, ovate, obtuse, incurved over the column, the middle lol)0 snbulnte 

 this lip has a yellow tinge, and the middle lobe is edged with a narrow, dark purph 

 line ; the concave disc is ocellated with minute, dark orange spots, and there is a pedi

 Anther-case terminal, but sunk into the top of the column, dwarf and imperfect.
