An illustration of a manchineel tree stem and fruit. The Manchineel tree (Hippomane mancinella) is a species of flowering plant in the spurge family (Euphorbiaceae), native to Florida in the United States, the Bahamas, the Caribbean, Central America, and northern South America. The name "manchineel" (sometimes written "manchioneel") as well as the specific epithet mancinella is from Spanish manzanilla ("little apple"), from the superficial resemblance of its fruit and leaves those of an apple tree. A present-day Spanish name is in fact manzanilla de la muerte, "little apple of death". This refers to the fact that manzanilla is one of the most poisonous trees in the world

Mangroves (generally) are trees and shrubs that grow in saline coastal habitats in the tropics and subtropics. The word is used in at least three senses: (1) most broadly to refer to the habitat and entire plant assemblage or mangal, for which the terms mangrove swamp and mangrove forest are also used, (2) to refer to all trees and large shrubs in the mangal, and (3) narrowly to refer to the mangrove family of plants, the Rhizophoraceae, or even more specifically just to mangrove trees of the genus Rhizophora. Mangals are found in depositional coastal environments where fine sediments, often with high organic content, collect in areas protected from high energy wave action.

"Notelaea ovata. 1. flower; 2. fruit." -Lindley, 1853

Mock Olive

"Notelaea ovata. 1. flower; 2. fruit." -Lindley, 1853

Leaves - compound (odd-feathered, leaflets, seven to nine); alternate; edge slightly and rather roundly toothed. Outline - of leaflets, mostly long oval, the lower pairs becoming smaller and more egg-shaped. Apex - long-pointed. Base - of the end leaflet, wedge-shape; of the others, more or less blunted. Leaf/Stem - rough throughout. Buds - large and round and covered with downy, yellowish-brown scales, or, in winter, with hard and grayish-white scales. Leaflet/Stem - lacking (or scarcely noticeable), except the short, roughish stem of the end leaflet. Leaflets - two to seven inches long, rough beneath, especially on the ribs; fragrant when crushed. Bark - rough, becoming cracked across, but not scaly. Fruit - rounded, slightly egg-shaped or oval, one and one half to two inches or more in length. The husk is about one fourth of an inch thick and splits nearly to the base when ripe. Nut - slightly six-angled, light brown, with a very thick and hard shell. Kernel - is sweet, but small. October. Found - common in dry woods, especially southward and westward. It grows in Southern Canada and I all the Atlantic States. General Information - All the Hickories are picturesque trees. Their tendency, even when standing alone, is to grow high, and with heads that, instead of being round, are cylinder-shaped to the very top, with only enough breaks and irregularities to add to the effect. This tendency is more marked in the Hickories than in any other of the leaf-shedding trees of North America. They are worthy of the name sometimes given them of 'the artist's tree." Hicoria, from a Greek word meaning round, in allusion to the shape of the nut.
