what is the difference between 覆盆子 and 树莓? As the title says what is the difference between 覆盆子 and 树莓? It feels like 覆盆子 is more formal / &quot;fancier&quot; than 树莓？ Or is it just traditional characters vs simplified?
Check wiki, basicly 覆盆子(Rubus idaeus) is one kind of 树莓(Raspberry), 树莓(Raspberry) also include 山莓 （Rubus corchorifolius）, 牛叠肚 (Rubus crataegifolius) etc.

树莓英文为“Raspberry”也可以指覆盆子（Rubus idaeus）但是它只是其中一种，广义来讲还可指悬钩子属内的部分物种。
