There were several bands named RAFFLESIA (ラフレシア) in the 90s and 00s, so details are murky.

This one participated in the 2001 Indies BOX omnibus with the song Ayatsuri Ningyou (操り人形). A song by the same name appears in a few DTs and MDs by a band named RAFFLESIA (ラフレシア), so assume that the two bands are the same. (Although the design of the DTs indicates that they were released several years prior to 2001.) One of those demotapes includes a photo showing a 4-member lineup. This band was apparently active in Nagoya (名古屋).
