Reading the bitterness
Ligustrum robustum is a plant of the privet genus in the olive family and differs at the family level from large-leaved kudingcha of the genus Ilex. A study includes small-leaved kudingcha derived from this species among the Chinese kudingcha lineages it analyzed. This description is based on the abstract.
A review says that Ligustrum robustum, the source plant for small-leaved kudingcha, came to be used as a substitute because of its botanical resemblance to large-leaved kudingcha (genus Ilex), its bitterness, and its history of use in folk medicine. The same review explicitly says, however, that no literature records on the origin of small-leaved kudingcha have been found in ancient texts.
The review also says that the leaves of small-leaved kudingcha (genus Ligustrum) are smaller and thinner than those of large-leaved kudingcha (genus Ilex), and that its flavor is less bitter than large-leaved kudingcha, making it easier to drink routinely. This is a qualitative account in the review, not a quantified measurement of bitterness intensity.
Sources for this overview
Checked for this overview: The record including it in an analysis as a source plant for small-leaved kudingcha.
Checked for this overview: The account of its adoption as a substitute because of morphological similarity, bitterness, and use history, and of the absence of records. / The qualitative comparison that small-leaved kudingcha is less bitter than large-leaved kudingcha.

Scope: Layer: literature (a qualitative comparison of morphology and flavor in a review).
Note: No overlap with existing claims. Adds a qualitative difference in bitterness intensity between large- and small-leaved types, not a quantitative value. The comparator is large-leaved kudingcha collectively, not Ilex latifolia alone.
