ments at first yellow, afterwards reddish, inserted into the calyx at the 
base of the corolla, to which they adhere at their orig'in, monadelphoiis; 
anthers coherent along their whole extent, red on the outside before 
the corolla opens, afterwards leaden coloured, densely covered with 
long white hairs which arise from the lines between them, yellow on 
the inside and yielding yellow pollen. Pistil rather shorter than the 
stamens ; style yellow, glabrous; stigma of two short blunt lobes, each 
having a tuft of hairs at its base ; germen half superior, conical at its 
apex, bilocular, placentae central, and covered with many small ovules. 
Popular and Geographical Notice. The genus Lobelia, 
though much reduced, may still require reform. Lobelia Cavanil- 
lesii and the species figured at tab. 139 of this work, are among those 
in which a diversity of habit makes it desirable that a good technical 
character could be formed by which to separate them. They are in 
cultivation in this country as species of Siphocampylus, but with that 
genus (see No. 227), they neither agree in character nor habit. 
Decandolle considers tab. 139, Lobelia laxiflora of Humboldt and 
Kunth, and this, to be merely varieties of the same. The much 
smaller growth of this and the character which I have drawn of it 
may, perhaps, keep them specifically distinct. In cultivation I have 
not seen them to vary so much as Decandolle thinks they do, 
but enough to make me little confident in this opinion. I believe 
they are both natives of Mexico. 
Introduction; Where grown; Culture. Lobelia Cavanillesii 
was first described in this country by Sir W. J. Hooker in 1837, with a 
statement that it was imported into the Botanic Garden, Glasgow, 
from Professor Lehmann of Hamburgh. It was received at the 
Botanic Garden, Edinburgh, from Mr. Rollison, in 1838, is now 
frequent in collections; its elegance and beauty entitle it to general 
cultivation. It is probable that Mr. Cameron’s observations regard¬ 
ing the culture of Siphocampylus bicolor (No. 139), may in some 
degree be applicable to this plant. 
Derivation of the Name. 
Lobelia in honour of Lobel, physician to Janies the VI of Scotland.
