This charming species comes very near to Epidendrum prcBcox Smith, but differs in having a much shorter spur, 

 in having a ventricose bract, and in the pseudobulbs being almost truncated.

Tliis species approaches nearest to Zingiber sqtiarrosum of Dr. Roxburgh, which I found abundantly about Rangoon, 

 but differs in having nuich broader, convex and ventricose bracts, ending in a very long cylindric point. It grows on 

 the hills near the banks of the Irawaddi, about Prome, on both sides of that river, where I saw it with unripe fruit In 

 September. The plants which were introduced thence into the Calcutta Garden, blossom freely during the cold and 

 rainy seasons. The spikes issue from the creeping roots, near the stems, or from the base of the latter, and are 

 barely elevated above the surface of the earth ; they are sometimes compound, that is, a spikelet is produced from 

 one or two of the lowermost bracts. , The whole plant possesses a very faint, though pleasant aromatic smell and 

 taste.
