BOUVARDIAS 251 
History. 
—having been introduced from Mexico just over a hundred years ago. 
For twenty years it remained the sole representative of the genus in 
this country ; then it was followed by B. versicolor from South America, 
and thirteen years later (1827) by B. longiflora, the subject of our Plate. 
B. angustifolia was introduced in 1838, B. flava in 1845, B. Cavanillesi; 
boldtit in 1874. With the exception of B. jasminiflora, which is South 
American, all these species came f 
rom Mexico. They have been much 
cultivated and crossed, with the result that there are a number of hybrids, 
some of which are more in request than the original species,
