What does cauline mean?
Cauline is a technical adjective used in botany to describe plant parts—most often leaves—that grow on or are attached to the stem of a plant, in contrast to those that arise from the base at ground level. The word comes from the Latin caulis, meaning 'stem' or 'stalk', a root it shares with such everyday words as cauliflower and kale. Botanists rely on the distinction between cauline and basal structures when identifying and classifying species, since whether leaves climb the flowering stem or cluster around the roots can be a decisive diagnostic feature. A dandelion, for example, produces only basal leaves, whereas a wild mustard bears cauline ones distributed along its stalk. Although precise and useful within scientific description, cauline remains firmly a specialist term, seldom encountered outside herbarium notes, field guides, and formal taxonomic writing.
adjectiveOf a leaf, flower, or other plant part: growing on or arising from the stem of a plant rather than from its base. Used chiefly in botanical description as the opposite of 'basal' or 'radical'.
- Relating to or borne on the stem of a plant, as opposed to the root or base.
"The species is easily identified by its cauline leaves, which alternate along the flowering stem."
"The dandelion's radical leaves are all clustered at the base, while the mustard plant bears both basal and cauline leaves along its stem."
"Botanists distinguish the two varieties by whether their flowers are cauline or arise directly from ground level."

Etymology of cauline
Cauline derives from the Latin caulis, meaning 'stem', 'stalk', or 'cabbage stalk', combined with the adjectival suffix -ine. The same Latin root gave English several other terms, including cauliflower (from caulis + floris, 'flower') and the vegetable names cole and kale, which reached English through Germanic borrowing. The adjective entered English scientific vocabulary in the eighteenth century as systematic botany developed its descriptive terminology.
How cauline is actually used
A technical term confined almost entirely to botany and scientific writing; rare in general prose.
Easily confused with cauline
Cauline derives from Latin caulis, meaning both 'stem' and 'stalk of cabbage', but it describes plant anatomy and has nothing to do with the vegetable itself.
