Tropical fruit

Citrus, spp., Unidentified giant lemon variety

This is a large Citrus species. The fruit were given to me years ago when I lived in Panama City's Old Quarter. Almost everyday I would visit a fruit vendor in Santa Ana to buy a small watermelon and a pineapple. He knew I worked with plants and collected fruit species so occasionally we would exchange fruit. I would bring miracle fruit, jaboticaba, jackfruit, curry tree fruit, and others, none of which he had ever seen. Him and his family would bring me highly regarded or lesser known fruit varieties from the interior of the country, giant Nance, Algarrobo (Hymenia coubaril), Mangos.

I never verified the species of this particular Citrus, it looks like some kind of Pomelo / Citron hybrid and has a relatively think skin compared to the size of the fruit. 

Any thoughts on the species?

Myrciaria glazioviana - Yellow Jaboticaba, Cabelluda

Sapindaceae, Blighia sapida, Akee, Seso Vegetal

akee2

Akee is native to and widely cultivated on the East coast of Africa. The English brought it from there to their colonies in the Caribbean where it is now well integrated. It is the national fruit of Jamaica.

The tree ranges in height from 10 - 25 meters. The canopy is open and broad. The fruit is a capsule in the form of a pear. When the fruit is ripe it splits open, exposing three shiny black seeds encased in a creamy white colored flesh, which is the part consumed. The fleshy arial has been described as looking similar to a small brain.

Akee is a curious and potentially dangerous fruit. If the unripe fruit is opened and the aril is eaten it can be deadly, or sufficiently poisonous to induce a coma. When picked before it is fully ripe the fruit contains a chemical that limits the body’s ability to release the backup supply of glucose that is stored in the liver. That supply is essential because once the body uses up the sugar immediately available in the bloodstream, an event that usually occurs several hours after eating, it depends on this glucose to keep blood sugar levels normal until the next meal. Without it, blood sugar plunges dangerously. Enough people have died from eating unripened akee to make it illegal to bring the raw fruit into the U.S although that restriction doesn’t apply to canned and properly processed akee.

Symptoms of akee poisoning can include uncontrollable vomiting, dizziness, severe hypoglycaemia, convulsions, coma and even death.

However, if the fruit is left to ripen and open itself, the flesh poses no danger whatsoever. All other parts of the fruit should never be eaten.  I remember visiting the Lancetilla botanical gardens Tela, Honduras. In their flier they discuss Akee, giving reference to the wife of the founder to the garden who had the mishap of consuming unripe Akee and, as a result, falling into a coma and eventually dying.

Akee can be eaten fried or boiled, typically with fish or meat. The texture is similar to eggs. A curious fruit indeed.

Akee is considered highly nutritious due to its high content of fats.

The tree thrives in a hot, humid climate and does not support long, dry periods. It is best grown in deep, well drained, soils. Liming is beneficial.

Psidium Cattleianum - Strawberry Guava

Native to Brazil, Cattley Guava was brought to China by the Portuguese. From China it was introduced into Europe where it is known as Strawberry Guava, it can also be found cultivated in the Mediterranean, Hawaii, Florida, California, Mexico and throughout Central America. P. cattleianum is a very attractive shrub, however it can grow up to eight m in height. The leaves are dark brown and somewhat glossy, the bark is shiny and peeling. The fruit are 3-4 cm in diameter, considered by many to be the best species of guava. There are red and yellow varieties.

The Strawberry guava is rich in vitamin C and contains 4.5% sugar, 6% fiber and 1.1% protein.

Pouteria campechiana - Eggfruit, Canistel

Canistel originates in Mexico and Central America where it has been cultivated since antiquity. It is now very common in Cuba and tropical America from Florida to Uruguay, it can also be found in the Philippines and Malaysia. The tree is typically managed between five and eight meters high. The fruit is five to ten centimeters long and round, or in the form of a egg with a point. The pulp is firm and almost powder, likened to the texture of a hardboiled egg yolk. It has a very rich flavor and texture. A fantastic fruit, in my opinion. I have heard that cheesecake made out of the fruit pulp is exceptional. Due to its almost powdery texture, the eggfruit is highly versatile and can be integrated into virtually any kind of blended drink or dish.

The fruit contains up to 40% carbohydrates, 2.5% protein, and is  great source of Vitamins A, B3, and C.

Canistel is adaptable to a wide variety of soils and can be grown in both tropical and subtropical climates, as long as there is no freeze. It is very drought tolerant.
