Rhamnaceae, Zizyphus mauritiana, Indian Jujube

,

Jujube is one of the five primary fruits in China, having been cultivated thereabouts for 4,000 some odd years, probably longer.  The fruit is very common in parts of Asia, and increasingly so in the Medeterranian. The tree is best adapted to dry tropical climates and can be found throughout the tropics, although it is not very common outside of Asia. 

The tree can reach 12 meters in height, although most of the ones I've encountered, propagated by approach grafting, are smaller, sprawling shrubs. In dry, colder areas the tree doesn't typically surpass 4 meters in height. 

The Indian Jujube (Z. mauritania) and the Chinese Jujube (Z. jujuba) can be distinguished by the underside of the leaves. The underside of the Indian jujube leaves is covered with an almost cream colored fuzz. The fruit is usually the shape and size of a olive, although improved Chinese varieties can be larger than 6 cm in length. Each fruit contains a stone with two seeds. 

The Jujube can be consumed in numerous ways: ripe or unripe, cooked, in sweets and jams, breads, cheeses, and a butter is prepared with the pulp. Juices are also made. In order to dry the fruits, one must wait until the process is initiated on the tree, the fruit ripens, becomes soft and then dries. The soft fruit has a higher concentration of sugars. Dried fruits are common, and can be conserved and consumed like raisins. 

The wood is very strong, often used to make agricultural implements, also used to make a top quality charcol. The tree is commonly used as a living fence and windbreak in arid regions. Leaves are used as food for silkworms. The bark is used for tanning. The leaves and fruit are an excellent animal forage. 

There are numerous superior grafted varieties of Chinese Jujube, including Lang, Li, Sui Men, Mu Shing hong, and Yu. There are over 125 known varieties of Indian Jujube in India, including "Gola", "Safeda", "Banarsi", and "Haichi". 

High quality fruits contain up to 21% sugar, 1.5% protein, and are rich in calcium, fosforo and vitamin C.

The trees can be propagated by seed, approach grafting, cuttings and air layer.

Cactaceae, Lemaireocereus thurberi, Organ Pipe Cactus, Pitaya Dulce

,

The Pitaya Dulce is another common cactus on the Baja peninsula. The nocturnal flowers are cream colored and bloom at night, closing the following morning. The Cactus bears an excellent spiny fruit about the size of a tennis ball containing sweet, pink flesh, with a flavor reminiscent of watermelon. The fruit pulp can be eaten fresh, or dried in the sun for future consumption. My Baja California field guide by Norman Roberts includes these interesting anecdotes concerning the Pitaya Dulce: That "Missionaries' records indicate the natives were generally hungry except during Pitaya season. Then they gorged on this wild harvest, spending the entire season in a state of euphoria." And that "the Natives defecated at a particular spot on the trail, later gathering their own dried feces to collect the tiny black Pitaya seeds that had passed through their intestinal tract undigested. These seeds were then ground into a meal to be eaten as a pozole. This was called "the second Pitaya harvest". The missionaries were thoroughly disgusted with this harvest and castigated the Aborigines for it." Of course, the missionaries never successfully survived for thosuands of years in this seeminly inhospitable landscape, which doesn't give them much room for criticizing the native inhbitants for their methods of adaptation.

The book then includes a note about the superb daiquiris that can be made from the Pitaya fruit.

The flesh of the Pitaya is traditionally used as snake-bite medicine, applied directly to the afflicted site.

Organ Pipe Cactus

Cactaceae, Lophocereus schottii, Old Man Cactus, Garambullo, Senita

This, I am pretty sure, is a young Old Man Cactus, growing on a ridge overlooking Bahia Magdalena in Baja, Mexoco. When the cactus gets larger gray, hair-like spines grow out of the top, giving  it a whiskered look, akin to an old man. The Cactus has small, pale pink flowers in the spring, which open at night, pollinated by bats and insects. Indians used to make tea from the cooked, sliced stalks to help relieve ulcerated stomachs. On the Mexican mainland slices of this species are sold in markets, used as a treatment for stingray wounds. The chopped stems were used to stupefy fish, also used as cattle forage.

The small red fruit was eaten by aborigines when other food was scarce.

Orchiadaceae, Encyclia caicensis, Parrot Cay, Turks & Caicos

Turks & Caicos native orchid, incredibly fragrant flowers on a chest-high spike, can be found growing on the edge of the beach in sand and limestone. The photo that I took (below) was used at www.orchidspecies.com, an incredible and extensive resource documenting the orchid species of the world.
