Matrotrophy associated with vertebrates and especially mammals, matrotrophy is found in 21 of 34 animal phyla, and is fairly common in 11 of those. It has arisen independently in more than 150 clades within Chordata and in more than 140 clades amongst invertebrates. Matrotrophy Matrotrophy is a form of maternal care during embryo development. Some flowering plants supplied the developing embryos for the first stages. The ovule has no stocks and the nutrients are provided by the "mother". In plants, matrotrophy is considered a critical evolutionary development preceding the origin of embryophytes and therefore essential to the evolution of land plants.
Phyla lanceolata Phyla lanceolata Phyla lanceolata is a species of flowering plant in the verbena family known by the common name lanceleaf fogfruit or frogfruit. It is native to the southern half of North America, including much of the United States except for the northwestern quadrant, and much of Mexico. It is resident in many types of moist and wet habitat, including disturbed areas, such as irrigation ditches. It is a perennial herb growing decumbent in a matlike form with spreading, trailing stems up to half a meter long, sometimes rooting at nodes. The lance-shaped or nearly oval leaves are up to
