This plant is nearly allied to the precedirg species (\>hich I have 

 alteo received from the Hon. E. Gardner iVoin KatnianUii, where it 

 is called KasfiWu loa, and from Mr. William Jack, who aiscover- 

 ed it in tlie Tnrrayee, bordering on the Nepala mountains). Both 

 agree in habit and beauty ; but my specits oiiTerg in the following 

 point. It is smaller and more slender, the whole heii^ht no<^ exceed- 

 ing two feet ; the ste7n perlec'.ly cylind.ic, as thick as a small goose- 

 quill, with a few branches at the base, The leaves are three or four 

 inches Ion"-, and about half an inch broad at the middle, riom thence 

 taperinw towards both ends, narrow at the base and almost petioled, 

 finely a'^uminated ; like the whole plant, smooth, rediincles ahno>t 

 as long as the leaves. Pedicels skndcr, about half an hich to an 

 inch Ion;?, terminated by a dark blue large flower. Laciiiics of die 

 Corolla narrower and move acuminated than in E. tetragomun. In 

 other respects the plants are very much like each other. — 2S. W,
