As to the article "Discussion on the Problems to the Pseuanthium and Euanthium Theory About the Occurrence of Hermaphrodite Flowers in Larch and Spruce" (Journal of Northeastern Forestry Institute,1982, Supplement for the College Anniversary Celebration, Pages 1—6), there is a fundamental disagreement between the authors and us in four main problems: 1. The authors observed hermaphrodite flowers in larch and spruce [but rather, bisexual strobiles in Larix gmelini (Rupr.) Rupr. and Picea Koraiensis Nakai——Gu An-gen and Sheng Guo-hi] in Harbin. They considered it a new discovery. We do not agree with what they observed was a new discovery because Chamberlan (8) and Florin [9—12] studied and reported bisexual strobiles of Coniferales in comparative details much earlier.2. The authors considered bisexual strobiles in Larix and Picea an atavism and thought that unbisexual strobiles of Coniferales evolved from their ancestor which had bisexual strobiles. The above judgement is completely unfounded.3. The authors thought that the possibility that flowers of Magnoliales have evolved directly from bisexual strobiles of Larix and Picea is much greater than from Bennettitales. Quoting a lot of facts from phylogery and Paleobotany, we have verified that the authors' point of view is rather subjective.4. Our opinion is not the same as the authors', and we believe that there is no possibility that Gymnospermae like Larix and Picea having such bisexual strobiles would become the ancestor of Angiospermae.
