This handsome flowering plant is of hybrid origin, and 
was raised in 1825, in the choice collection of R. H. Jen- 
kinson, Esq., from a seed of P . incomparabile that had 
been fertilized by the pollen of P. eocimium or P. oblatum. 
We have named it in compliment to our much respected 
friend, David Stewart, Esq., of Great Russell Street, 
Bloomsbury, formerly Superintendant of the fine establish¬ 
ment of the late J. J. Angerstein, Esq. of Woodlands, 
near Blackheath, at that time the most celebrated garden 
in the country, for forcing fruits of all descriptions, and 
for the choicest collection of the best grown Conservatory 
plants that we ever beheld, many of which flowered there 
for the first time in this country: to Mr. Stewart we are 
indebted for the first rudiments of our education on the 
cultivation and propagation of plants, having been for 
some time one of his pupils, and by his permission we were 
allowed to try different experiments, which has afterwards 
enabled us to establish quite a different system in the culti¬ 
vation and propagation of plants, than any hitherto used : 
how we have succeeded, we leave those to judge who have 
seen and understand the subject: though we have now 
quitted that employment for the present, for one still more 
agreeable to our taste, that of publishing different works 
on Botany and the Cultivation of Plants. 
One of Mr. Stewart’s principles was to imitate and 
assist nature as much as possible, which principle we have 
always strictly adhered to, quite in opposition to the gene¬ 
rality of Horticulturists. 
The present plant being related to P. ignescens, re¬ 
quires the same treatment; an equal mixture of light turfy 
loam, peat, and sand, will suit it very well; and cuttings 
root freely, planted in the same sort of soil.
