TL;DR: In this article , a comparative morphometric analysis of internal and external seed features in the 16 dicot species representing 10 families from the Thal desert (Pakistan) using scanning electron microscopy was conducted.
Abstract: Abstract Micromorphological and ultrastructural data have been helpful in determining the evolution, classification, ecology and phylogeny of seed plants. Taxonomic utility of seed characters has been explored, although the value of micro-structure in selected dicot angiosperms from desert areas has not been adequately addressed. We conducted a comparative morphometric analysis of internal and external seed features in the 16 dicot species representing 10 families from the Thal desert (Pakistan) using scanning electron microscopy. Seeds were mostly minute and small and slightly larger than 1 mm in length except for Acacia nilotica, Astragalus hamosus and Prosopis juliflora. Seeds varied in shape from elliptical to obovate, D-shaped, reniform, rhomboid and ellipsoidal. The cell outline, periclinal boundaries and sculpture pattern of the anticlinal wall were generally rugulate, reticulate and striate, papillate and rugose or rarely undulating granulate. The seed coat also comprises diverse forms of epicuticular projections and texture. The phenetics of 84 character-states using principal component and dendrogram statistics supported the affinities among desert species. Here, we identified micromorphological similarities and differences among dicot angiosperms to determine their systematic relationships. Graphical Abstract

TL;DR: Different micromorphological characters will help in identification of authentic plant species as they varied in their type as unicellular in H. indicus whereas multicellular trichomes in L. reticulata and T. indica.
Abstract: Asclepiadaceae family contains many medicinally important species of which Hemidesmus indicus, Leptadenia reticulata and Tylophora india were selected for the present micromophological studies. It was revealed that different types of stomata like anomocytic, anisocytic and paracytic were present only on abaxial surfaces of leaves. However maximum anomocytic stomata i.e. 25.50±0.43 were observed in L. reticulata followed by H. indicus (24.54±0.31) and T. indica (11.36±0.16). Similarly, observation for trichomes revealed that they were present on abaxial surface in H. indicus and T. indica whereas in L. reticulata on both of the surfaces present. They varied in their type as unicellular in H. indicus whereas multicellular trichomes in L. reticulata and T. indica. This different micromorphological characters will help in identification of authentic plant species.

TL;DR: This new species is characterized by a shrubby or arborescent habit, very large unifoliolate leaves, long petioles, and fasciculate, pseudoracemose inflorescences.
Abstract: Amyris amazonica, from the Amazonian forests of northeastern Ecuador, is described. This new species is characterized by a shrubby or arborescent habit, very large unifoliolate leaves, long petioles, and fasciculate, pseudoracemose inflorescences.
