The correct matching for botanical suffixes to taxonomic hierarchy levels is option (4): (A)-(II) class, (B)-(IV) Kingdom, (C)-(III) sub-tribe, (D)-(I) sub-class. This question assesses knowledge of ICBN (International Code of Botanical Nomenclature) suffix conventions for plant taxonomy ranks.

Option Analysis

Option (1): (A)-(III), (B)-(II), (C)-(I), (D)-(IV)

• –opsida (III sub-tribe): Incorrect; –opsida denotes class (e.g., Lycopsida).

• –bionta (II class): Incorrect; –bionta indicates Kingdom (e.g., Plantae → Embryobionta).

• –inae (I sub-class): Incorrect; –inae is sub-tribe (e.g., Selagininae).

• –idae (IV Kingdom): Incorrect; –idae is sub-class (e.g., Magnoliidae).

Option (2): (A)-(IV), (B)-(I), (C)-(III), (D)-(II)

• –opsida (IV Kingdom): Incorrect; too low rank for Kingdom.

• –bionta (I sub-class): Incorrect; –bionta is higher (Kingdom).

• –inae (III sub-tribe): Correct.

• –idae (II class): Incorrect; –idae is sub-class, not full class.

Option (3): (A)-(I), (B)-(III), (C)-(II), (D)-(IV)

• –opsida (I sub-class): Incorrect; –opsida is class.

• –bionta (III sub-tribe): Incorrect; –bionta is Kingdom.

• –inae (II class): Incorrect.

• –idae (IV Kingdom): Incorrect.

Option (4): (A)-(II), (B)-(IV), (C)-(III), (D)-(I)

• –opsida (II class): Correct (e.g., Filicopsida).

• –bionta (IV Kingdom): Correct (e.g., Chlorobionta).

• –inae (III sub-tribe): Correct (e.g., Pteridinae).

• –idae (I sub-class): Correct (e.g., Alismatidae).

Introduction to Match List I with List II Suffix Group Hierarchy

In botanical nomenclature, Match List I with List II suffix group hierarchy follows ICBN rules where specific endings denote taxonomic ranks. Suffixes like –opsida (class), –bionta (Kingdom), –inae (sub-tribe), and –idae (sub-class) standardize classification from Kingdom to lower levels, crucial for pteridophytes and angiosperms in exams.

Suffix Meanings Decoded

• –opsida: Class level (e.g., Bryopsida in mosses).

• –bionta: Kingdom/supergroup (e.g., Plantobionta).

• –inae: Sub-tribe within tribes.

• –idae: Sub-class under classes.

Exam Tips for Suffix Questions

Memorize via mnemonics: “Opsida for Class, Bionta Kingdom massive.” Option (4) is standard in pteridophyte taxonomy like Selaginella (Selaginellaceae, Selagininae). ​
