Anatomy and foliar architecture of two Mexican species of Ternstroemia Mutis ex L.f. (Pentaphylacaceae)

Background: Many Mexican Ternstroemia species mainly inhabit the tropical montane cloud forest. These have been misidentified in herbaria due to their morphological resemblance.
 Question: Are there foliar anatomical and micromorphological characters with diagnostic value that allow discriminating between of Ternstroemia?
 Study species: sylvatica Schltdl. & Cham., T. lineata DC. subsp. (Pentaphylacaceae Engl.), 2018-2019.
 site date: Tropical forests at Trans-Mexican Volcanic Belt Sierra Madre Oriental.
 Methods: Botanical specimens were collected removed from herbarium sheets. The leaves prepared through cleared, dehydration paraffin inclusion techniques observe describe them.
 Results: showed specific features plants humid environments, such as thin cuticle, mesophyll scarce parenchyma palisade, abundant intercellular spaces spongy parenchyma, pigments help capture light serve protection. share a festooned broquidodromous venation pattern, anomocytic stomata, closed collateral vascular bundle surrounded by perivascular fibers. Both are differentiated leaf shape, abundance collenchyma layers, lenght palisade number stomata per square millimeter on abaxial surface.
 Conclusions: We support validate some recorded for reject previous generalizations made worldwide genus. This research is first attempt study anatomy, architecture, micromorphology Pentaphylacaceae.
