The following terms and definitions apply to this document.
3.1
higherplants

in lower plants.
3.2
spore plant cryptogams
Plants that reproduce by spores.
Note. Including algae, lichens, mosses, ferns, etc.
3.3
seed plant spermatophytes
Plants propagated by seeds.
Note. Including gymnosperms and angiosperms.
3.4
Bryophytes Bryophytes
Small herb, with differentiation similar to stem and leaf, lack of vascular tissue in the body. Gametophyte generations predominate in life history. Sporophytes produce spores, but
Can not survive independently, must be parasitic on the gametophyte to live.
3.5
ferns pteridophytes
Most of them are herbs, few are woody, and the differentiation of roots, stems and leaves occurs, and vascular tissue is produced in the body. The sporophyte generation predominates in the life cycle, and many

composition. The category code is represented by 1 letter, the family code is represented by 3 digits, the category code is represented by 3 digits, and the type code is represented by 3 digits
The variable type code is represented by a 2-digit number. The code structure is shown in Figure 1.

A Bryophyta (see Table 1);
B Ferns (see Table 2);
C Gymnosperms (see Table 3);
D Angiosperm phylum (see Table 4).
The sorting order of the families, genera, species and varieties in this document under the phylum Botany is in alphabetical order by Latin name.
