Thelocactus conothelos aurantiacus

Thelocactus conothelos aurantiacus is often overlooked gem. Plants have orange, red or yellow flowers and some forms have nice colorful spination like at the picture. When not in flower, at first glance the plant can be mistaken for Stenocactus, with dense radial spines obscuring the stem morphology. Of cause with Thelocactus there is no wavy ribs there.
