I suspect Lamb 哈斯 and Super 哈斯 (“Oo Lala” as it’s commonly called but I hate that name) are distinct cultivars. My understanding is that Super 哈斯 is from Louisiana.
Lamb 哈斯 will sometimes produce fruit that have more of a defined “neck” which Super 哈斯 never seems to produce. Pretty much all of our Super 哈斯 fruit uniformly look like this:
On a side note, regular 哈斯 has produced much better quality fruit than Super 哈斯, which often ripens unevenly and develops splits in the skin.
