Tam (1988) separated Balanophora spicata from B. laxiflora on the number of perianth parts and the shape and sculpture of the rhizome by comparing the original description and figures. However, Hansen (1972) had already pointed out that Hemsley's description is too short to provide adequate characters and his illustration misleads in suggesting 5-merous male flowers with 5 horse-shoe-shaped anthers to be the rule, while 6-merous male flowers are in fact in greater portion in the type material. The shape and sculpture of the rhizome is of less taxonomic importance, as Hansen (1972) suggested. Thus, it is better to treat them as one species.

   據《臺灣植物志》(Fl. Taiwan, 2:255. 1976)把 /B. parvior/ Hayata, /B. formosana/ Hayata,和 /B. morrisonicola/ Hayata 等均歸併於本種中,這三個種的標本,作者沒有看過,暫不列入。
