Our garden is indebted for the sceds of this plant to Lieut. 
Strachey, who gathered them on the plains of Thibet, at an ele- 
vation of 15,000 feet above the level of the sea. I was at first 
disposed to refer it to the Belenia prealta, Dene. in Jacquemont's 
Voy. vol. iv. p. 116. t. 120, but that figure will hardly justify 
such a conclusion. The flowers are not half the size, their calyx 
is longer and narrower, and the fructiferous calyx is too much 
elongated and curved. Be that, however, as it may (and the 
figure is evidently made from a very indifferent specimen), the 
genus, if really a good one, intended to include Hyoscyamus ort- 
entalis and H. physalodes, should bear the name we have here 
adopted, given by Mr. Don to the section of Hyoscyamus to 
which those species belong. 
Descr. Root probably perennial. Stem herbaceous, a good 
deal branched, terete, clothed everywhere, as well as the foliage, 
with glandular down. Leaves alternate, petiolate, ovate, acute,
