Eupatorium glandulosum, one of the best of the white- 
flowered, greenhouse species, was introduced, according to 
Paxton, in 1826, and it was figured in the ‘“‘ Botanical 
Register” (t. 1723) in 1835. It is there recorded that 
the Horticultural Society received seeds from Mexico some 
years previously through a Mr. Canning. Subsequently, 
“scarcely before 1840,” it was introduced into Madeira 
and the Canaries, where it is now excessively common. 
It is a valuable winter plant for the conservatory or 
greenhouse where there is plenty of space. The drawing 
was made from a plant that flowered at Kew in March, 
1906. In its native country it grows in humid situations 
at altitudes of 5,000—8,000 ft. 
In spite of discrepancies in the description, I think there 
is no doubt that H. trapezoidewm, Kunth, belongs here.
