From an inspection of the specimen from which Dr. 
Hooker's figure of his Dendrobium Harrisoniae was taken, 
wc have ascertained that it is the same as the plant now 
published, notwithstanding the difference in the colour of 
their flowers. The plant which Dr. Hooker examined 
appears to have been in a less vigorous state of health than 
that before us, and to have produced only one flower, 
instead of two, or probably a greater number. 
A native of South America. The plant from which our 
drawing was taken was kindly communicated by William 
Cattley, Esq., from his Conservatory at Bamet. A robust 
stove parasite, flowering in September. 
IVo group of plants has undergone greater chan2:es, in 
consequence of accurate investigation, and the application 
of modern analytical principles of botany, than the genus 
Dendrobium. As it stands in Willdenow's Species Plan- 
tarum, published twenty years ago, it consists of 25 species. 
Of these, D. sangiiinciun has been detached, by Mr. Brown, 
under the name of Broughtonia ; D. graminifolium, by the 
same distinguished Botanist, as Octomeria ; and D. rusci- 
folium, as Pleurothallis. To the latter genus, D. racemijiorum 
has been referred by the writer of this article. D. poly-
