Dr. Britton called attention the 6th volume of Hough’s Wood 
Sections, which was now ready for distribution and to the publica- 
tion of Mr. Small’s monograph on Polygonum and exhibited copies 
of both. 
The announced paper of the evening was then read by Mr. H. 
A. Siebrecht, entitled «Some Interesting Orchids of Cultivation.” 
The paper was handsomely illustrated with living specimens in 
bloom. The paper dealt with the history of the earliest collec- 
tions and collectors of orchids, and-traced the development of 
their cultivation up to the present time. Interesting facts concern- 
ing their native habits and the best methods of growing the dif- 
ferent classes were presented, and a discussion concerning their 
special habits of growth and fertilization was introduced.
