Note
|
Saurauia Seibertii is apparently endemic to Panama. The specimen collected by Allen in Bocas del Toro is aberrant. It lacks the many-flowered inflorescence so characteristic of the other specimens, but agrees with them in the foliar clustered and tufted trichomes, the smooth leaves, which are nearly glabrous above, and the reticulating tertiary veins.
