嗢鉢羅花（上烏骨反梵語也細葉青色蓮花也古云漚鉢羅或名優鉢羅皆訛也此花最香最大人間絕無雪山無熱惱池有）。

Utpala flower (嗢鉢羅花: the first character has the fanqie 烏骨反; Sanskrit. It is a blue lotus flower with narrow petals. In older texts it was written as oupaluo [漚鉢羅] or youpoluo [優鉢羅], both of which are corruptions. This flower is the most fragrant and the largest; it does not exist among humans at all, but exists in the Lake of Anavatapta [Lake without Torment] in the Snow Mountains).
