Nice. It’s a container for holding leaves from the areca palm, for which both the leaves and nuts (known as betel nuts) are chewed for their stimulant and narcotic effects, despite their association with oral and esophageal cancers.
The nuts and leaves are chewed together with slaked lime (calcium hydroxide), to help release the primary psychoactive compound ‘arecoline’; sometimes with the addition of flavourings or breath-fresheners such as coconut, dates, sugar, menthol, saffron, cloves, aniseed, cardamom, and many others. Sometimes tobacco is an additional component.
Often the leaf container is part of a set that includes the containers and accoutrements for preparing and storing the other components. Like this set from Thailand:

Here’s one of the leaf containers, also from Thailand:

This site shows a more ornate one incorrectly assigned as a ‘flower holder’ but it would be way too unstable for that.

The practice of chewing this stuff is widespread in most countries of Southern Asia, among Chinese immigrants, and was introduced to the Caribbean in colonial times. The containers can be found in brass, silver and silver gilt, often with enamel or niello decoration. I would think yours is late 19th or early 20th Century and could be from any one of a number of Asian countries.
