High Yielding Points from TAXONOMY

1. Shapes of corolla:
a. Cruciform: cross(x) like corolla eg. Cruciferae
b. Tubular: tube-like eg. sunflower
c. Papilionaceous: butterfly shape eg. legumes
d. Bilabiate: 2 lipped eg. libiatae
e. Personate (masked): bilabiate corolla with a narrow opening

2. Types of nomenclature:
a. Holotype: Specimen used by the author to confer scientific name to species
b. Isotype: Duplicate of holotype
c. Paratype: specimen cited with the original description other than holotype or isotype
d. Neotype: If the original specimen is lost it can be substituted by another specimen collected from the same locality
e. Lectotype: Specimen selected from the original material selected to serve as nomenclature type [@ HIPaNL]

3. Famous book ‘Species Plantarum’
was written by Carolus Linnaeus but ‘Genera Plantarum by Batham and Hooker
