LOBELIA DENSIFLORA. 
It is a native of Brazil, and was received in 1 846 by Messrs. Rollisson from M. Pinel, 
a botanist and collector of plants, residing in the Brazils. It was introduced under the 
name we have adopted, given, no doubt, on account of the labellum, resembling a fan when 
spread out. 
We see no objection to its retaining the name of 0 . fldbelliferum, more particularly when 
it is considered that it w 7 as so named by M. Pinel, who first found it, and who has no doubt 
described it under that appellation in his unpublished works. 
In cultivation it should be potted in turfy heath-mould, mixed with potsherds and 
chopped sphagnum, filling the pot half full of drainage, and elevating the soil in the pots, 
in the same manner as for Stanhopeas ; or it may be attached to a block. 
It requires abundance of heat, water, and humidity, during the season of growth, and 
to be shaded from the violence of the sun’s rays ; and in the time of its torpidity, it should 
be kept nearly dry. Increase is effected in the usual way. 
The generic name is derived from ogkos, a tumour ; the plants belonging to this genus 
having warts, tumours, or other excrescences at the base of the labellum.

Amongst the numerous species of Lobelia known and described, we find no description 
agreeing with the subject of our present plate, which we observed blooming in the Nursery of 
Messrs. Knight and Perry, King’s Road, Chelsea, in 
October, 1848, at which time we made our present 
drawing. 
It is a plant of considerable beauty, being very 
dwarf, seldom exceeding eight inches in height, half 
of which forms the dense pyramidal spike of intense 
blue flowers ; the lower part of the spike usually 
measures about two inches in diameter, and tapers to 
a point at the extremity ; the foliage is of a bright 
and lively green, and not being coarse, it admirably 
contrasts with the deep blue of the flowers. 
The plant is hardy, or nearly so, and if its shoots 
can be induced to spread along the ground, it will 
prove an excellent kind for planting in small flower- 
beds in the open air, being of low growth, and from 
the colour of the flowers, very conspicuous. 
It may be propagated by division of the roots, and 
should be grown in a light rich soil. 
The generic name is given in honour of Mathew Lobel, author of various works, and 
particularly that called “leones Plantarum.” He was born at Lisle in 1538, became 
physician and botanist to James I., and died in London in 1616.
