Equus (genus) 54 million years ago (Mya). These animals had three toes on the hind feet and four on the front feet with small hooves in place of claws, but also had soft pads.<ref name="doi10.1126/science.1105458"></ref> Equids developed into larger, three-toed animals (e.g. "Mesohippus") during the Oligocene and Miocene. From there, the side toes became progressively smaller through the Pleistocene until the emergence of the single-toed "Equus". The genus "Equus", which includes all extant equines, is believed to have evolved from "Dinohippus", via the intermediate form "Plesippus". One of the oldest species is "Equus simplicidens", described as zebra-like with a donkey-like head shape.
Agapanthus africanus at the close of the 17th century. Unlike the more common "A. praecox", it is not generally suitable as a garden plant, and will not tolerate extended freezing temperatures. Agapanthus africanus Agapanthus africanus (African lily) is a flowering plant from the genus "Agapanthus" native to the area of Cape of Good Hope in South Africa. "A. africanus" is more difficult to grow in gardens than "A. praecox", and almost all plants sold as "A. africanus" are actually "A. praecox". It has a short stem bearing a tuft of long, narrow, arching leaves 10–35 cm long and 1–2 cm broad, and
