Are hawthorn and hawthorn the same thing?

Generally speaking, hawthorn and hawthorn are a kind of plant. But to be honest, this question is an unanswerable one. This is because hawthorn is not a scientific name, but a common name. The problem with common names is that they may refer to many kinds of plants, and different places refer to different kinds of plants. For example, the example given by @lalunasun. Judging from the characteristics of small fruit, sweet taste and clumps described by her, it is likely to be sorbus or wild hawthorn. Mountain red is a popular name for this plant by local people. Let's look at hawthorn again. This is the scientific name, which only refers to the hawthorn of Crataegus in Rosaceae. Some places are really called mountain red. So there is no strict correspondence between hawthorn and hawthorn. Whether it is a species or not depends entirely on the local secular.
