    For the Chinese names of Bauhinia blakeana (the city flower of Hongkong) and Bauhinia variegata, we commonly call them 洋紫荊 and 宮粉羊蹄甲 in Hongkong and they are also adopted in the Checklist of Hong Kong Plants 2004. This is different from that of FOC, Chinese Plant Name and South China Botanical Garden Checklist in efloras. Kindly clarify the discrepancy.
