Three striking species of the large South American 
genus Chlorewa have been figured in this work, namely, 
C. longibracteata, Lindl. (t. 7909), QO. erispa, Lindl. 
(t. 7955), and a third, now known as C. Ulantha, Rolfe, 
which appeared in 1830 (t. 2956), under the name of 
Neottia ? grandiflora, Hook., but was afterwards made the 
type of a new genus, and called Ylantha grandiflora, Hook. 
(sub t. 2990). his remarkable plant is still only known 
from the original example, which flowered in the Glasgow 
Botanic Garden as long ago as the spring of 1829, and of 
which only a single flower is preserved in Sir Wilham 
Hooker’s Herbarium, now at Kew. The dried flower has 
an expanse of over four inches. It is recorded as having 
been received from the Rev. Lansdown Guilding, and, 
although the locality is not mentioned, it has been con- 
jectured to be the Island of St. Vincent, in the West 
Indies, though probably not indigenous. From what is 
now known of the distribution of the genus, this con- 
OctoBer Ist, 1906.
