Finally found the Bradley issue where Gordon Rowley goes through the paintings, so grabbed a PDF and its a big help. This entry we look at an Opuntia and whatever that is growing down below.
Here is another plant with a fig connotation but with quite a different form. Opuntia is the Greek name given to the prickly pear or Indian fig, the word supposedly coming from the ancient town of Opus in Greece, known as the town of figs. This fig should not be confused with the fruit of the broadleaved tree Ficus to which it has a likeness in the shape of the fruit only. Opuntias grown freely and often to a large size in Mediterranean countries but they came originally from the hot countries of the New World including Mexico and Brazil. Before the arrival of the Spaniards, the Aztecs were producing a gum called nopal from the plants from which they made various remedies including one for burns in which nopal was mixed with honey, eggs and herbs.
The prickly pieces are easily broken off* to make new plants, hence it is a familiar house plant, which with care can be brought into bloom in spring' the flowers may be yellow, orange, red or purple. It is important that they should not be overwatered and one recommendation is that they should only be given water when the weather report for Mexico says rain.** The flattened ovoids are really enlarged stems in which water is stored and the stomata from which the prickles emerge are vestigial leaves which may be raised areoles, barbed bristles or white spines. These have the power of hindering transpiration or holding dew, and are arranged in a geometrical spiral, one of nature's favourite structures.
The fruits of many opuntias are edible*** and are supposed to be nutritious. They are eaten raw or cooked as a vegetable and can be made into a fermented drink, while the plants with the spines burnt off are sometimes fed to cattle. There is one species, Opuntia cochenillifera, which was cultivated in tropical America to provide food for the insects**** that were used to make cochineal., before synthetic food dyes were manufactured.
The blurb for this is mostly right and yes that is an Opuntia in the foreground (Opuntia compressa) and the succulent at the base is Jordaaniella dubia, and not as I thought, a Tillandsia. I never knew about making fermented drinks from it but the nopals when treated to remove the spiny glochids, are used as a vegetable.
* Indeed they are, you haven't lived until you have an armful of small glochids along with a chunk of stem clinging to your arm. Almost impossible to remove without some pain and the use of tweezers.
** Which is cute, but wrong the standard cactus instructions stand here. No watering between Halloween and April Fools day and then only weekly. The Opuntia tribe can stand some cold though being as its the most northernly (Manitoba) and Southernly (Maihuenia down in Patagonia) growing species of cactus.
*** Have done this but found it to be waxy and the seeds are bullet hard. Not sure about growing them though.
**** OK confession time, my uncle worked for the dye factory down near the tip and gave me a small bottle of the mealy bugs that were processed to make cochineal. The only time a cactus grower really wants mealy bug on their plants.
