Thorny Treasures of the Chihuahuan Desert by Jean Nance O uch!! How many times have we all uttered that, or worse, while walking in the Chihuahuan Desert, where every plant in the landscape seems to be armored with some kind of sharp spine, prickle, or needle? These plants are "well-defended" with good reason, as it turns out, because those sharp defenses protect some tasty and nutritious contents. In fact, some of our thorniest and most useful inhabitants are “indicator plants” of the Chihuahuan Desert; that is, they typify this eco-region and help to define its limits, such as the endemic lechuguilla, our smallest agave. The sharp-tipped lechuguilla and other agaves, sotols, yuccas, ocotillos, cacti, and mesquites were staples that desert life was built upon. Archaeological sites such as Hinds Cave in Val Verde County or Carved Rock Shelter in Brewster County give us insights into daily life as far back as 5000 years ago. Carvings, pictographs, and artifacts show a broad botan- ic history, from wooden artifacts like arrows and lances made from stalks of sotol, yucca, or lechuguilla, to fiber artifacts like basketry and cloth made from agave and yucca leaves. Hard seeds and pods, such as mesquite beans, were ground in mortar holes, and storage pits were lined with fibrous materials like prickly pear pads and grasses. Stone hand axes and other tools showed evidence of agave harvesting and food preparation. The scarlet flower buds on an ocotillo. Mesquite branch with leaves and long thorns.

Agaves, a New World family, have been a valuable source of food, fibers, medicine, and shelter for thou- sands of years, and were even cultivated centuries before European exploration. After Europeans arrived, agaves were quickly export- ed to Europe and were cultivated in the Mediterranean by 1586. Agaves provide two types of food: pulp (mescal) and sap (aguamiel). Pulp can be derived from the heart, leaves or stalk and is a good source of calcium. Slow cooking in stone-lined baking pits was the favored approach for pro- ducing the best pulp, which could be made into cakes, syrup or beverages. The Apache glazed dried cakes with agave juice to improve their storage life. Pulp was often combined with other foods, such as walnuts, juniper or sumac berries, or various greens, and you can’t mix a margarita without today’s best-known product, tequila, which is distilled from cooked agave hearts. Cenizo First Quarter 2013 Mescalero Apaches received their name from their regular consumption of mescal for food and drink, including a fermented drink also called mescal. Parry’s Agave (Agave parryi), commonly called the “mescal agave,” was considered a staple food of the Apaches, and is one of the agaves whose range was possibly extended by pre-Columbian cultivation. Agave sap can be made into unfermented or ferment- ed drinks. The sweet (high sucrose) sap contains vitamins B and C and some amino acids. Agave flowers, seeds, sprouts and nectar are edible. Flowers were often boiled and dried for storage, even though yucca flowers were preferred. Lechuguilla (Agave lechuguilla) seed sprouts are tasty, and some tribes roasted flower stalks over coals, but lechuguilla’s best contribution might have been its fibers, woven into items such as ropes, baskets, or matting. Cave evidence indicates that lechuguilla was greatly preferred for fibers, composing up to 94 per cent of netting sam- ples. Lechuguilla’s other major use was soap made from roots or leaves. All agaves have some history of medicinal applica- tions, from treating wounds and snakebites to digestive problems (fresh agave juice is known as a laxative), but their most promising use might come from the chemical precursors to cortisone and other medicinal steroids. In particular, lechuguilla has yielded cortisone in laborato- ry testing, and root extracts have shown antibacterial properties. Folk medicine prescribed it for treating wounds, infections or snakebites. SOTOL or DESERT CANDLE (Dasylirion leiophyllum, Dasylirion texanum) Sotol might look like a large grass, but watch out for the sharp sawlike teeth along the edges of the long leaves on this member of the lily family. Sotol ranks alongside lechuguilla and other agaves as a desert staple, and was used in similar ways. Leaves and fibers were woven into cordage and weavings. Dried flower stalks provided materials for corrals, porches, roofs and other structures. As with agaves, sotol hearts were roasted in a rock “sotol pit” and then eaten or dried, made into cakes or flour or preserved for later consumption. Young flower stalks were also roasted. A stout drink called sotol was made by fermenting the cabbage-like heart, and was a favorite alcoholic beverage of the Kickapoo as recently as the 1970s. THE YUCCAS The many species of yuccas were such important resources that they are one of only a few wild plants identified in prehistoric petroglyphs. Fibers might have
