Crescit in Nepalia. Wallich. if. 
In the Lambertian Herbarium is a single specimen of this 
plant, lately sent by Dr Wallich, the indefatigable superinten- 
dant of the Calcutta Botanic Garden, with the name Incarvillee 
species attached to it. The specimen, otherwise very perfect, is 
without flowers ; but from the great affinity it bears to Didy- 
mocarpus, it is very probable that it agrees also with it in the 
form of its flowers, as well as in the disposition and figure of its 
anthers 
* Since the publication of my little paper on Rhododendron, &c. in the Phil. 
Journ. (vol. vi. p. 47.) a friend has pointed out to me, that the union of the genus 
Asalea (excluding Azalea procumbens) with Rhododendron, has been long ago pro- 
posed by R. A. Salisbury, Esq. in his observations on Rhododendron chrysantkum, in 
the late periodical work entitled “ Paradisus Londinensis.” I take this opportunity 
of mentioning, that the following improvements and corrections may be made on 
the character of Rhododendron: P. 49. for “ basi hirsuta.” read “ saepius basi hir- 
suta.” After ‘‘ 5-valvis,” insert “ (in R. arhoreo lO-locularis, 10-valvis).” For 
apice dehiscens,” read “ ab apice dehiscens.” The columella should have been 
described columella 5-angula (in R. arhoreo 10-angula).”
