colour; the two upper ones broadest, obovate, rather un¬ 
equal sided, flat at the point as if truncate, stained with 
dark velvet, and marked with numerous dark lines that 
cross each other, and form net-work all over the petals : 
lower petals narrower, spatulately ligulate, of a bright 
blood colour, also marked from the base with dark veins 
that branch all over the petals. Filaments 10, united at 
the base, 7 bearing the rudiments of anthers, but no pro¬ 
per ones, not even sterile ones in our specimen. Style 
short, flesh-coloured, hairy all its length. Stigmas long, 
dark purple, spreading, the points reflexed. 
The present splendid and very distinct plant, is of hy¬ 
brid origin, and was raised from a seed of P. sanguineum 
last Spring, by Mr. W. Smith, in the collection of the 
Earl of Liverpool, at Coombe Wood; the seed had been 
fertilized by the pollen of P. aurantiacum , or some nearly 
related sort, so that it is intermediate between two very 
distinct tribes, partaking in an equal degree of both; we 
do not know when we have seen a more splendid flower ; 
its colour being quite dazzling when in full bloom. We 
have named it in compliment to our respected friend, 
Mr. J. C. Loudon, of Bayswater House, Author of seve¬ 
ral valuable and popular works on Horticulture and Agri¬ 
culture, as the Encyclopaedia of Gardening, and Agricul¬ 
ture, Gardener's Magazine, Natural History Maga¬ 
zine, Sfc. 
As the present plant is intermediate between two rather 
tender sorts, it will require a good Greenhouse to preserve 
it through the Winter; the best soil for it is an equal pro¬ 
portion of light turfy loam, peat, and sand, and the pots 
to be well drained with small potsherds, that the wet might 
pass off readily, as nothing would be more injurious to it 
than too much moisture in Winter. It may be increased 
by cuttings, or from pieces of its roots; the latter must be 
planted with their points above the ground, or they will be 
liable to rot.
