calyx three times as long as the ovary, while the calyx of P. tomentosa is said to have 
a calyx which equals the ovary in length. The calyx of my specimens is about half as 
long again as the ovary. Strange to say, however, the figure in Mart. Fl. Bras. /. c. (t. 57) 
which purports to be that of P. Poeppigiana represents a plant whose calyx is but 
little, if at all, longer than the ovary. This has caused me much difficulty in naming 
my specimens. I should suggest the probability of four of Mueller's species, evidently 
closely allied as they are, being mere varieties of one; these four are P. Barcellana, 
Poeppigiana, tomentosa, and Uberabana. | | Brasilia, Guiana, Venezuela. |

The stamens of this plant are often inserted at different heights upon the corolla; so, 
too, are the hairy pads near the points of insertion of the stamens. The figure in Mart. 
Fl. Bras. (t. 59) is misleading, as it does not show the pads, although Mueller correctly 
describes them.  [ Bras. Or., Goyaz, Amazonia, Peruvia. }
