This very rare plant was found by Mr. Hartweg, on his 
first arrival in Mexico, at a place called Zaquapam, at the foot 
of Orizaba, and was raised among the first collections that he 
sent to the Horticultural Society. Considering the warm 
climate of which it is a native, it was expected to prove 
tender, and the event has shewn it to be so ; for we have no 
species yet in our gardens so impatient of cold. In fact, it 
must be regarded strictly as a greenhouse plant, to which 
any amount of frost would be fatal. 
It is a hard-wooded graceful plant, ve apt to run up 
with a single stem, without producing lateral buds, and when 
that is allowed to happen, its beauty is much impaired. For 
some time, indeed, it remained in that state in the large con- 
servatory of the Horticultural Society. At last, by binding it 
down, so as to check the rise of the sap, the lateral buds were 
enabled to expand, and now the specimen is well furnished 
with branches, and is above six feet high. 
Its flowers appear in the latter part of the year (October 
to December), and are agreeably sweet-scented. 
So far as experience has gone, it appears to be the most 
easily propagated by cuttings of the half ripe wood, or by 
grafting on B. aquifolium. For soil it seems to like sandy 
loam and peat.
