Scientific Name
The scientific name describes the species of an organism. The first word is the plant’s scientific genus and the second is the specific epithet. This two-word binomial is sometimes followed by other taxonomic descriptors, including subspecies (denoted by “ssp.”), variety (denoted by “var.”), form (denoted by “f.” or “forma”), and cultivar (denoted by single quotation marks).
Plant Family
The family to which the plant belongs.
Propagation Material
The first part (material code) describes the material used to create the plant. The most common codes are “SD” (seed), “EX” (existing plant), “PT” (plant), “CT” (cutting), “SC” (scion), “SG” (seedling), and “GR” (graft). The second part describes the lineage the plant is derived from. The last part describes the year of propagation.
Collection Data
The first part indicates provenance (place or source of origin) using a letter code (“W” = wild, “G” = garden, “Z” = indirect wild, “U” = uncertain). The second part lists the plant source. For wild-collected material, the collector, collection number, and country are given.
