本文根据形态学和系统发育学证据，对中国兰科一新种金花独蒜兰进行了描述。新种与独蒜兰属其他成员之间的详细形态比较表明，金华独蒜兰与P. bulbocodioides和P. formosana相似，但不同之处在于具有啮蚀状顶缘的唇和不包裹柱的侧裂片。为了探讨台湾桃花心木的系统发育位置，对台湾桃花心木和台湾桃花心木的核核糖体ITS和质体DNA（matK外显子、trnT-trnL间隔区、trnL外显子和trnL-trnF间隔区）进行了序列测定。形态学和分子生物学证据支持金花蕨为一新种的假设。
Pleione jinhuana , a new orchid from China, is illustrated and described based on morphological and phylogenetic evidence. Detailed morphological comparisons between the new species and other members of Pleione indicate that P. jinhuana is similar to P. bulbocodioides and P. formosana but differs in having a lip with an erose apical margin and lateral lobes not enfolding the column. To explore the phylogenetic position of this species, nuclear ribosomal ITS and plastid DNA ( matK exon, trnT-trnL spacer, trnL exon and trnL-trnF spacer) were sequenced for P. jinhuana and individuals of P. formosana collected in Taiwan, Fujian and Zhejiang Provinces. The morphological and molecular evidence support the hypothesis that P. jinhuana is a new species .
