Echinocereus pectinatus (Scheidw.) Engelm., also known as the rainbow cactus; commonly remains single, but old plants sometime branch and form a loosely clumped cluster. It has yellow, pinkish or brownish spines loosely pressed to the surface or spreading widely, pectinate, and intertwining with those of the other areoles. It produces very beautiful, brilliantly coloured flowers with spiny tube, which later develop into Gooseberry-like fruits rich in sugar and said to be very delicious.
