Definition
In old English law, *herba* is a Latin term referring to a plant, herb, or weed growing on land. The word appears in legal instruments and early common law texts primarily in compound constructions that define specific rights or obligations related to vegetation growing on property. Two forms appear with distinct legal significance:
1. **Herba exotica** — literally "foreign herb," used in early English case law to denote exotic or imported plant matter, most notably tea, in contexts involving customs, duties, or commodity classification.
2. **Herbæ dampnosa** (also *herbae noxiae*) — "noxious weeds" or harmful plants, appearing in agrarian law and land management obligations, particularly in connection with a tenant's duties to manage and clear damaging vegetation from leased or held land.
The term has no ongoing significance in modern legal practice but surfaces in historical land records, lease instruments, and early treatises on agricultural tenure.

Common Language
**Modern common usage (Wiktionary):** An herb; a plant used for food, medicine, or scent; also, in botany, any non-woody vascular plant.
**Historical common usage (Webster's 1913):** "A plant or vegetable with a soft or succulent stalk or stem, which dies to the root every year, and is not woody or persistent; also, vegetation in general; green plants collectively."
The common meaning and the legal meaning share a root but diverge in application. In everyday usage, *herb* carries culinary or medicinal connotations. In its legal contexts, *herba* was a neutral category term for vegetation on land — it described what grew, not what it was useful for. The legal significance lay in property rights over that vegetation or in the obligation to manage it, not in the plant's intrinsic character.

Why It Matters in Research
Researchers encountering *herba* in historical English legal sources will almost always find it embedded in one of two research contexts: commodity law (particularly customs and excise disputes from the early eighteenth century) or agrarian tenure obligations (particularly manorial and leasehold sources from the medieval and early modern periods).
**The Bunbury trap.** Burrill cites *herba exotica* for the proposition that tea qualifies as an herb under early English customs classification. The underlying source is *Bunbury's Reports*, a collection of eighteenth-century exchequer cases. Researchers working with commodity taxation or customs history should note that classifications like *herba exotica* were contested and occasionally circular — courts were defining categories in part by fitting new imported goods into Latin taxonomies inherited from earlier law.
**The Fleta connection.** The *herbæ dampnosa* usage traces to *Fleta*, a late thirteenth-century Latin treatise on English law. Fleta's treatment of noxious weeds appears in the context of agricultural waste and tenant obligation. Researchers studying waste doctrine, dilapidations, or medieval leasehold obligations will find this a useful link. The category of "noxious weeds" is not incidental — it connects to broader doctrines about a tenant's duty not to impair the productive value of land, a predecessor to modern waste doctrine.
**Compound forms are the research target.** Searching for *herba* alone in historical sources is unlikely to be productive. The term functions as a root in compound constructions. Researchers should search *herba exotica*, *herbæ dampnosa*, or *herbage* (the anglicized form, which carries its own distinct legal history regarding grazing rights) depending on the context they are investigating.
**Herbage as successor term.** The legal concept of rights over vegetation on land — grazing rights, profit à prendre of herbage — migrated into English law under the anglicized term *herbage*, which developed an independent doctrinal history distinct from the Latin *herba*. Researchers should not assume continuity of meaning between *herba* in medieval Latin sources and *herbage* in later common law without tracing the specific right at issue.

Historical Dictionary Support
Burrill's entry is brief but precise. He identifies *herba* as a term of old English law, correctly supplies the two principal compound forms, and provides source citations that remain traceable: Bunbury's Reports for *herba exotica* and Fleta, book 2, chapter 81 for *herbæ dampnosa*.
No other historical dictionaries in the current Law Mind corpus provide entries for *herba*. Burrill's entry is therefore the primary reference, and researchers should note its limitations: the entry does not address the anglicized law of herbage, the right of *herbagium*, or the relationship between *herba* terminology and profit à prendre doctrine. These gaps are significant for anyone moving from the term in a Latin source into the broader common law of land rights.
The Latin dictionary materials confirm that *herba* in classical Latin encompassed grass, green crops, and herbage generally — a broader semantic range than the narrow legal uses Burrill identifies. This breadth is relevant context: legal Latin narrowed the term through specific compound formations rather than using *herba* in isolation as a term of art.

Jurisdictional Note
*Herba* as a legal term of art is specific to the English legal tradition and its Latin-language sources. It does not appear as an operative term in Scots law, civil law systems, or American common law sources. American researchers will encounter *herba* only when working directly with English medieval or early modern primary sources.
