‘West China :—Open moist shady situations in pine forests on 
the mountains of the Chungtien Plateau, Yunnan. Lat. 27° 30° 
Alt. 12,000 ft. Plant of 9-16 ins. Flowers deep golden-

The plant is very definitely characterised by its stems glabrous 
and shining at the base, by its corolla of a fine golden yellow, by 
its long-petioled leaves, slightly hairy with large lobes, and above

wrinkled-alveolar seed-coat. It differs from Phth. chinense, 
Bge., by its relatively small yellow corolla, by its stems glabrous 
_at the base and not glandular; its seeds have coats of the same 
colour, mes are three or four times larger. It differs from Phth,
