Note
|
It is named in honor of Dr. Scott Mori, distinguished collector of tropical American plants and authority on the Lecythidaceae. The new species is distinguished by its relatively large collar- shaped stipules and by the thin interdental veil of the calyx. The smoothness of the pyrenes is also noteworthy.
