JUANULLOA AURANTIACA. 
WITH AN ENGRAVING. 
The genus to which our present subject belongs is one founded 
by those distinguished botanists and travellers, Hipolito Ruiz and 
Jose Pavon, to whose labours on the vegetation of Southern 
America the botanical world are so much indebted. It was ori¬ 
ginally published in their excellent work, the ‘ Flora Peruviana,’ 
the name being a compliment to that celebrated Portuguese tra¬ 
veller, Don Juan de Ulloa, who made many valuable discoveries 
and additions to the early history of the American continent, and 
was at length canonized by his countrymen. 
Two species have been known in our collections for some few 
years, which were at first referred to the genus Brugmansia , and 
it was only at a comparatively recent date that their correct sta¬ 
tion was determined by Sir W. J. Hooker, who, in his account of 
the first known species, J. 'parasitica , tells us that, although 
propagated and become common in our gardens, “it is in fact 
one of the rarest of plants, speaking botanically,” which we 
understand to refer to its geographical location in a natural 
state. 
The plant just mentioned was introduced from Peru in 1824, 
and the subject of our illustration followed it in 1840. Both are 
now by no means scarce, for, thanks to the untiring exertions of 
cultivators and the advanced state of the cultural art, productions 
with a degree of merit at all commensurate with the trouble of 
growing them, are speedily increased and distributed. 
The qualifications of the particular species under notice to a 
station among the standard plants of a collection, are neither few 
nor of minor consequence. Like the individuals of the allied 
genus Brugmansia, of which it was at first supposed to form part, 
this plant is distinguished by a vigorous and rapid development 
of new parts, a copious habit of blooming, and the ease with 
which it may be managed. The most valuable characteristic, 
however, is the free manner in which it bears flowers through the 
winter, when their large size and brilliant warm colours render 
them particularly attractive. Wherever flowers are desired in 
winter, this plant should always be grown.
