‘ XXIX. TROPHOLACER. 199 
Obs.—Tbe above are among the more distinguished and pee species of this vast and favorite genus. 
Innumerable varieties produced from seeds and propagated by cuttings are equally common and oiten of 
superior beauty. No genus seems to be regarded with such universal favor for green-house plants as 
this. The species and their multitudes of hybrid creations, produced by modern ingenuity, are cultivated 
with assiduous attention by nearly every family which makes the least pretensions to taste through- 
out the civilized world.
