AMAR YLLIDACEiE. 
ing’ with Amoena and Guianensis in having petiolated broad 
leaves, it may be always recognized by their greater thick- 
ness and consistence, by a more robust tube, and much more 
conspicuous flowers. It differs from all the other species in 
sending up its young leaves not successively, but at periods 
(perhaps twice a year) simultaneously, the flower-stem just 
preceding them. P. fragrans, Redoute, is certainly a va- 
riety of Speciosa with the foliage of var. 2, but a shorter 
tube ; it is more robust, and has a longer tube than Amoena. 
This species is the most beautiful, and is cultivated without 
any particular care in the stove. The petiolated sorts are 
all natives ol very hot countries, and it may be that the 
habit becomes obsolete in a more temperate climate ; for I 
find in the plants of this species and of Amoena raised from 
seed produced in my stove, a disposition to depart from the 
decidedly petiolated habit of the parent, and produce leaves 
of a more lorate form. 
2. Guianensis. — Folia petiolata, mollia, successiva ; 
tubus limbo longior. Leaves softer than Speciosa, 
successive ; tube 5-8 inches long, longer than the 
limb. 
Var. 1. Prmceps. — Bot. Reg. 4. 265. Tube 6 inches 
or more; limb 4-5. 
Var. 2. Undulata. — Kunth. 1. 222. Tube 5 inches, 
cup toothed in the intervals. 
Var. 3. Tubiflora. — Salisbury. Hort. Soc. Tr. 1. 341. 
Tube 8 inches, cup not toothed. 
This species occurs in a variety of forms along the coast 
of Honduras and Guiana, always distinguishable by broad 
petiolated foliage of a thinner texture than speciosa, much 
slenderer and less conspicuous flowers, with a tube reaching 
from 5 to 8 inches in length. The undulation of the limb, 
from which var. 2. has been named, is of little importance in 
this genus ; I have seen it vary in the same umbel. The 
dentation of the cup is not less variable. Var. 1. has long 
petioles, var. 3. much shorter, but endless shades of variation 
will be found between them. They are plants of very deli- 
cate constitution, and if planted in light loam in a dry stove 
they soon perish. I believe them to be natives of alluvial 
soil and a half swampy situation. A plant of var. 3. which 
I have lately placed in water, seems not to be offended by it, 
but perhaps will not thrive there permanently.
