What does pyxis mean?
A pyxis is a small, often decorative box designed to hold small valuables or preparations. Its modern sense can suggest a jewel box, cosmetic case, or other compact container, and the word often carries a formal, antiquarian, or scholarly tone. In botany, a pyxis is a specialized reproductive structure found in certain plants, particularly lichens, in which spores are released as the structure opens. Because the ordinary meaning is relatively uncommon, “pyxis” is especially useful in historical, literary, museum, or scientific writing where the precise, traditional term is preferable to the general word “box.” The word ultimately comes from ancient Greek, where it referred to a small box or container, and entered English through learned and classical usage.
A small box or case, especially for holding jewelry, cosmetics, medicine, or similar items.
"The portrait shows a noblewoman holding a small jewelled pyxis."
This sense is literary and historical in tone; in everyday speech, “box” or “case” is more usual.
A specialized reproductive structure in certain plants, especially lichens, that opens to release spores.
"The lichen's pyxis splits open and exposes the powdery spores inside."
This is a technical botanical term, especially associated with lichens.
The standard plural changes the internal vowel and ends in -es.
"The collection contains several small silver pyxides."
A pyxis is a box with a scholarly air: its name comes from the ancient Greek word for a small container, and in botany it describes one of nature’s tiny precision storage cases.

Where does pyxis come from?
The word comes from ancient Greek πύξις (pyxis), meaning a box or container. Latin borrowed the term as pyxis, and English later adopted it in learned contexts. The botanical sense developed from the same Greek word and refers to a small, specialized reproductive receptacle.
How pyxis is actually used
In ordinary modern English, “pyxis” is literary or specialized and is much less common than “box” or “container.” The botanical sense is technical and should be used in a scientific or horticultural context.
