The Clusiaceae or Guttiferae Juss. (1789) (nom. alt. et cons. = alternative and valid name) is a family of plants formerly including about 37 genera and 1610 species of trees and shrubs, often with milky sap and fruits or capsules for seeds. It is primarily tropical. More so than many plant families, it shows a large amount of variation in plant morphology (for example, 3 to 10 petals, fused or unfused petals, and many other traits).According to the APG III, this family belongs to the order Malpighiales. The APG III system reduced the circumscription of this family to just 14 genera and about 595 species.

One feature which is sometimes found in this family, and rarely in others (e.g., Malpighiaceae), is providing pollinators with rewards other than pollen or nectar; specifically, some species offer resin which bees use in nest construction (all three rewards are found in different species of the Clusiaceae).

Sandwich

A sandwich is a food item, typically consisting of two or more slices of bread with one or more fillings between them, or one slice of bread with a topping or toppings, commonly called an open sandwich. Sandwiches are a widely popular type of lunch food, typically taken to work or school, or picnics to be eaten as part of a packed lunch. They generally contain a combination of salad vegetables, meat, cheese, and a variety of sauces or savoury spreads. The bread can be used as it is, or it can be coated with any condiments to enhance flavour and texture. They are widely sold in restaurants and cafes.
