luted fiotrets of Thyrs. nitidus, Th. strictus (see our Tab. 4378),

late Nees von Esenbeck, entirely from specimens in the Hooke- 
rian Herbarium derived from Assam (Mrs. Mack, Griffth, 
Hooker) and from Khasya (Grifith, Hooker). From seeds sent 
from Bhotan by Mr. Booth, our plants were raised by Mr. 
Nuttall, and they flowered for the first time, in a warm stove, in _
