Frequent in the Himalayas, from 1500 to 11,000 feet altitude, 
extending thence to Japan and New South Wales. The species 
is strongly defined by the long-fimbriate, not merely bristly, 
hypogynous sete ; but, in its great range, it varies much in size 
and in the size of its heads ; whence its copious synonymy.

Both Nees and Franchet regard this important Chinese food- 
plant as only a cultivated form of Æ. plantaginea. The authentic 
example of Bretschneider has neither flower-heads nor rhizome, 
The plant, from China, cultivated at Buitenzorg (Miquel’s 
tuberosa?) is gigantic, the culms more than 3 feet high, more 
than 4 in. in diam., the spike 1-3 in. thick ; but nothing is known 
about its tubers.
