Because of the special lack of worldwide knowledge about the family lauraceae
Lauraceae
The Lauraceae or Laurel family comprises a group of flowering plants included in the order Laurales. The family contains about 55 genera and over 3500, perhaps as many as 4000, species world-wide, mostly from warm or tropical regions, especially Southeast Asia and South America...

in general, very little is known about their diversity. The knowledge of this family to national level, is that to be expected in countries with limited economic means with the vast majority of species indeterminate or even poorly determined. On the other hand, a high percentage of recently described new species come from collections made in these countries. Therefore an increase in the study of family, at national level, is of utmost importance for the progress of the systematics of the family in general. Recent monographs of genera of lauraceae in small and medium genus, up to 100 species, have produced a high increase in the number of known species. This high increase in the number of species is expected for other genus, particularly for those with more than 150 species recorded, bringing an expected considerable increase in the total number of species of the family.
