       Abstract: The modern center of differentiation and distribution of Petrocosmea Oliv. is located in Southwest Mountains of
       Chinaꎬ and this genus can distribute to India (Assam)ꎬ Myanmarꎬ Thailand and Vietnam. It helps researchers to better
       understand the flora of China & Indo ̄China Peninsula and the plant biodiversity of Petrocosmea in above ̄mentioned areas
       because many new taxa and new national records of this genus were discovered and published in recent years. For instanceꎬ
       Petrocosmea martinii (H. Léveillé) H. Léveillé and P. sericea C. Y. Wu ex H. W. Liꎬ formerly considered as endemic
       species of Chinaꎬ with the former was once thought to be distributed in Guizhouꎬ North Guangxi and Southeast Yunnan and
       the latter is only distributed in Southeast Yunnan Provinceꎬ are also found in Vietnam at present. This finding raises the
       number of Petrocosmea known from Vietnam are five species. Thusꎬ the discovery of two new national records of Petrocosmea
       hints more new taxa and records will be discovered in those areas where are adjacent to Southwest mountains of China in the
       future. The descriptionsꎬ illustrationsꎬ conservation status assessment of two newly recorded Petrocosmea and identification
       key to all known Petrocosmea from Vietnam are here provided for checking by researchers.
       Key words: North Vietnamꎬ Key of Petrocosmea in Vietnamꎬ Flora of Vietnamꎬ Flora of China
