This plant is nearly allied to the preceding species (which idee 
also received from the Hon. E, Gardner from Katmandu, where it 
is called Kashwa Soa, and from Mr. William Jack, who discover- 
ed it in the Turrayee, bordering on the Nepala mountains). Both 
agree in habit and beauty ; but my species differs in the following 
point. It is smaller and more slender, the whole height not exceed- 
ing two feet ; the stem perfectly cylindric, as thick as a small goose- 
quill, with a few branches at the base. The leaves are three or four 
inches long, and about half an inch broad at the middle, from thence 
tapering towards both ends, narrow at the base and almost petioled, 
finely acuminated ; like the whole plant, smooth.  Peduncles almost 
as long as the leaves. Pedicels slender, about half an inch to an 
inch long, terminated by a dark blue large flower. Lacinie of the 
Corolla narrower and more acuminated than in E. tetragonum. Ia 
other respects the plants are very much like each other.—N. W.
