'TRECHONJZETES. 
Among the few interesting plants gathered in my journey 
over the Cordillera in the January, 1825, was one found upon 
the eastern descent of the Cumbre, towards Las Cuevas, at an 
altitude of 11,500 feet, in a very dry and arid situation, which 
circumstance suggested the above generic name, from rpnx@ 
locus asper, vaérns incola. Specimens of the same plant have 
lately been sent to this country by Mr. Bridges; and as it has 
not been yet described, I now offer the result of my long 
recorded observations, from which it will be seen to possess 
characters very distinct from Jaborosa and its congeners.
