t. 1989 of this work. The same species (P. edulis) is also 
well represented by Mr. Ker in Bot. Reg. t. 152 as P. m- 
carnata, 6; while the incarnata, 3, of the last-mentioned 
work is an entire-leaved variety of our plant, with the 
peduncles much shorter than I have ever seen them in 
reality. The two species are abundantly different in the 
following particulars. P. incarnata has comparatively 
small serratures to the leaves, the petiolary glands much 
below the blade of the leaf, very long peduncles which are 
generally equal in length to the leaf; three small bracteas 
under the flower, set so apart, however, as not to form an 
involucre, minutely serrated in the upper half, and having 
from one to three large glands below where the serratures 
commence ; a large flower with no distinct tube at the base 
of the calyx, and a purplish-blue filamentous crown, rather 
longer than the calyx and corolla—In P. edulis the leaves 
are more coarsely serrated, the two glands at the very apex 
of the petiole, the peduncles are much shorter than the 
leaves, the bracteas are three, large and very deeply serrated, 
forming an involucre under the flower, the serratures often 
glandular: the base of the calyx is contracted into a tube, 
and the filamentous crown is much paler and shorter than 
the corolla. The germen is sometimes downy in P. edu/is, 
but the colour of the fruit is said to be different in the two ; 
lurid purple in the last-mentioned; yellow in our plant: 
from which circumstance I have derived our English spe- 
cific name, for I have never seen any thing flesh-coloured 
about the blossom. P. incarnata extends from Virginia to 
the extreme southern point of the States, and I believe not 
of South America. It is No. 121 of Mr. Drummonp’s 
Louisiana Collection. P. edulis I have never received in a 
wild state, except from Brazil.
