This is by far the finest species of the genus as yet 
known. It was discovered by Griffith in Bhotan, at eleva- 
tions of 3000 to 5000 feet, and named, from imperfect spe- 
cimens, after its discoverer by Schott, who however failed 
to recognize it amongst the species subsequently brought 
by myself from Sikkim, and transmitted to him for exami- 
nation, and he consequently gave to the latter the name of 
A. Hookerianwm. A comparison of Griffith’s Bhotan speci- 
men with my own does not enable me to detect any 
difference between them, though the latter appears to affect — 
a much higher elevation, for I have never gathered it much 
below 8000 feet of elevation, and it ascends to 10,000 feet. 
Under A. utile (Tab. 6474) I have described the use to 
which the tuberous roots of this and other species of
