   • 1960, A. K. Yegna Narayan Aiyer, P. Abraham, Cultivation of Cloves in India (I.C.A.R. Bulletin), New Delhi: Indian Council of Agricultural Research, →OCLC, page 5:

     This was another experimental garden started under Dr. Berry as a ‘Nopalry’ or place for the rearing of the cochineal insect on cacti, which however, became a sort of experimental garden where exotic plants were received as they arrived in the Port of Madras and were nursed and looked after until they could be despatched to the interior stations.

   • 2013, Leslie Morgan Steiner, The Baby Chase:

     Three years later, the unwatered cactus was still about two feet tall, a dark green color. The watered cactus was a paler green, its trunk visibly swollen with moisture. It had grown to be over five feet tall.

2. Any succulent plant with a thick fleshy stem bearing spines but no leaves, such as euphorbs.

In modern English, the term cactus properly refers to plants belonging to the family Cactaceae. With one exception, all are native to North and South America. The sole exception is Rhipsalis, a jungle epiphyte found in tropical Africa, Madagascar, and Sri Lanka, as well as North and South America. Informally, cactus is used to refer to any stem succulent adapted to a dry climate, notably species from genus Euphorbia with forms reminiscent of Cactaceae. These succulents are better described as "cactoid" or "cactiform" unless they are actual members of the Cactaceae.
