Demonic Lamp Flower is a mamono realm flower capable of storing mamono mana from the air, which causes it to glow. Unusual for mamono realm plants, humans also find it beautiful. Since it doesn't have an arousing effect or monsterization capability, they are even sold in human realms. It was later discovered that Demonic Lamp Flowers taken out of mamono realms have a mild hypnotic effect which causes humans to be drawn toward things with mamono mana.
Monster Girl Encyclopedia World Guide - Side I: Dragonia mentions the Dragon Lamp Flower as a red variation only found in The Pillar of Heaven dungeon of Dragonia, while Monster Girl Encyclopedia World Guide - Side III mentions the Nevian Rose as a rose subspecies peculiar to the Nevia Island of Court Alf[1].

World Guide II
A flower that lives all over the mamono realm. In the mamono realm these flowers are extremely popular. They have light, pale colored petals with the property of storing mamono mana from the air and glowing faintly. Many of the plants of the mamono realm are queer or ominous, but these plants are still beautiful even from the human perspective, which is a rarity. Especially at night when lots of demon light flowers are glowing in flowerbeds. They're a famous part of the mamono realm, and popular with both humans and monsters. Because of their beauty, they are taken out of the mamono realm and sold in the human world.
The flowers themselves don't have the effect of driving humans mad with lust or changing humans into monsters. They were thought of as a safe plant, but in recent years, we've come to understand that they cause a kind of hypnotic effect, and that caused an uproar in scientific circles. If humans continue to view these flowers after being mesmerized, they will then naturally be drawn towards things that include mamono mana, in other words, things that induce monsterization such as the mamono realm's water, fruits, drugs, etc. In the case of men, it is supposed that they will more easily be charmed by the monsters themselves. That sort of trait hasn't been confirmed in the demon light flowers that live in the mamono realm. According to one theory, once they are taken out of the mamono realm, they can no longer get mamono mana from the air, so they make their owners bring objects infused with mamono mana so they can get it somehow. It may be the case that they have this feature so that if possible, they'll have their owner become a monster, or they'll make their owner bring a monster, so that they can perpetually gain mamono mana.

"Dragon Lamp Flower"
This is a variation of the demonic lamp flower, which can only be found near the top of the Pillar of Heaven. Perhaps because they grow in the thin air near the top of the tower and are nourished solely on dragons' mana, they have red petals that differ from normal demonic lamp flower, and are known to glow a little more brightly at night than demonic lamp flower. In Dragonia, the dragon lamp flower is used as a bouquet in the "mating ceremony", and its strong luminescence allows it to be planted on the rooftops of buildings as a landmark to ensure that dragons do not lose sight of their destination during their nighttime flights. They are also used as magical tools that witches and dark mages attach to the end of their brooms, and while the demonic lamp flower gives off a faint light in a lantern, the dragon lamp flower gives off a strong glow, making them a popular item among those who are proactive and passionate about love.
