Dendrobium nodatum, Rekhenb.jil. ms. 



This charming Dendrobium is a Moulmein plant, sent by Mr. 

 Parish to Messrs. Hugh Low and Co., of the Clapton Nursery, 

 whence flowering specimens were forwarded in 1862 to Pro- 

 fessor Reichenbach, who, finding the species to be undescribed, 

 gave it the very characteristic name of ' nodalum? doubtless 

 in allusion to the prominent ■ nodes ' into which the stems are 

 divided. I am not aware that the Professor has yet published 

 any technical description of the plant. 



"D. nodatum is a free and rapid grower, and speedily produces 

 dense tufts of its singular knotty stems. These unfortunately 

 lose their leaves before the gay flowers, which are always single 

 {i.e. not in pairs or racemes), make their appearance, a circum- 

 stance that points to the desirableness of giving the plant a de- 

 cided season of growth and rest. Hitherto the flowers have been 

 produced at irregular times, and less profusely than in its native 

 country, but I apprehend that, as is the case with some other 

 Dcndrobia, we shall find that the stems when two or three years 

 old, will bloom more freely than when of more tender age." — J. B. 

 Descr. Sterna, rather than pseudobulbs, nearly a foot long, 

 slender, branched, articulated, rooting at the joints, and there 

 singularly nodose or swollen. leaves upon the younger shoots 

 mostly terminal, two to three inches long, oblong and obtuse. 

 Flowers on the old stems, from which the leaves have fallen,
