She inclined her head to indicate the endless sand, broken only by an occasional yucca or chickweed.
It was sweetened with the juice of yucca fruit.
To the southward, as the valleys become increasingly sandy and saline, even the sage-brush disappears, and little vegetation besides the cactus and the yucca is to be seen.
The yucca is a source of starch.
The plants are generally perennial herbs growing from a bulb or rhizome, sometimes shrubby as in butcher's broom (Ruscus) or tree-like as in species of Dracaena, Yucca or Aloe.
Yucca and several allied genera are natives of the dry country of the southern and western United States and of Central America.
- Yucca gloriosa.
The gathering and preparation of "ixtle" fibres from the agave and yucca forms another important industry, the fibre being sent to Tampico for export.
Then, there are the mangrove-fringed coasts and the dripping wooded slopes where rare orchids thrive, and above these, on the inland side of the sierra, a treeless, sun-scorched table-land where only the cactus, yucca, and other coarse vegetation of the desert can thrive without irrigation.
There is but little natural vegetation to be seen - ragged yucca trees, many species of agave and cactus, scrubby mesquite bushes, sage bushes and occasional clumps of coarse grasses.
The natural and forest products of Mexico include the agave and yucca (ixtle) fibres already mentioned; the " ceibon " fibre derived from the silk-cotton tree (Bombax pentandria); rubber and vanilla in addition to the cultivated products; palm oil; castor beans; ginger; chicle, the gum extracted from the " chico-zapote " tree (Achras sapota); logwood and other dye-woods; mahogany, rosewood, ebony, cedar and other valuable woods; " cascalote " or divi-divi; jalap root (Ipomaea); sarsaparilla (Smilax); nuts and fruits.
Cordaites, a tall plant (20-30 ft.) with yucca-like leaves, was related to the cycads and conifers; the catkin-like inflorescence, which bore yew-like berries, is called Cardiocarpus.
The vegetation is distinctively tropical, including among its economic products cacao, cotton, sugar, tobacco, rice, maize, yucca (also known as cassava and mandioca), peanuts, bananas, sweet potatoes, yams, arracacha (Conium moschatum, H.
They are still independent of political control, live in permanent settlements, till the soil (producing Indian corn, beans, yucca and plantains), and have developed some rude manufactures.
Agriculture.-The agricultural industries on which the export trade depends are almost wholly restricted to the western lowlands, and include cacao, coffee, cotton, sugar, tobacco, rice, yucca and sweet potatoes.
The tree yucca often attains a height of 20 to 25 ft., and a diameter of 1.5 ft.
New Mexico has such a great range of elevations that all four of the zones of vegetation into which the South-West has been divided according to altitude are found within its limits; namely, the zone of cactus, yucca and agave (3000-3500 ft.), where grass is scanty; the zone of greasewood and sage-brush (3500-4900 ft.), where there is little grass, and the cactus species are less numerous; the zone of the cedar (4900-6800 ft.); and the zone of the pine and fir (6800 - 10,800 ft.), in which grass is more abundant.
And cactus and yucca in the S.
From the great juicy, leafless, branchless stalk of the yucca, soap is prepared, and strong fibres useful in making paper, rope and fabrics.
In the most arid regions there is a small growth of green in the rainy season, and a rich display of small wild-flowers, as well as the enormous flower clusters of the yucca, and blooms in pink and orange, crimson, yellow and scarlet of the giant cactus and its fellows.
Other food and economic plants are coffee, rice, tobacco, sugar-cane, cotton, indigo, vanilla, cassava or "yucca," sweet and white potatoes, wheat, maize, rye, barley, and vegetables of both tropical and temperate climates.
Cactus and yucca occur in the west.
