Campylandra Baker was published in 1875. Subsequently, various authors have
either united it with Tupistra Ker Gawler (sometimes recognizing it as a s
ubgenus or section of Tupistra) or maintained it as a separate genus. The p
resent authors regard Campylandra as a separate genus on account of its hav
ing filaments only proximally (vs. almost wholly in Tupistra) adnate to the
perianth tube, anthers as high as or higher (vs. lower) than the stigma, a
shorter style, and a 3-lobed (vs. peltate to mushroom-shaped) stigma; this
separation is confirmed by molecular phylogenies. In preparation for the a
ccounts of genera in the Convallariaceae for Flora of China, Volume 24, it
is therefore nec essary to transfer into Campylandra 12 species hitherto tr
eated under Tupistra, namely: I: annulata H. Li & J. L. Huang, T. chinensis
Baker, T. delavayi Franchet, T. emeiensis Z. Y. Zhu, T. ensifolia F.T. Wan
g & Tang, T. fimbriata Handel-Mazzetti, T. jinshanensis Z. L. Yang & X. G.
Luo, T. liangshanensis Z. Y. Zhu, T. lichuanensis Y. K. Yang, J. K. Wu & D.
T Peng, T. longipedunculata F.T.Wang & S. Yun Liang, T. verruculosa Q. H.
Chen, and T. yunnanensis F.T. Wang & S. Yun Liang. It is also necessary to
transfer two species originally described under a related genus, Rohdea Bot
h, but later transferred to Tupistra: T. tui (F. T. Wang & Tang) F. T. Wang
& S. Yun Liang (R. tui F. T. Wang & Tang) and T. urotepala (Handel-Mazzett
i) F. T. Wang & Tang (R. urotepala Handel-Mazzetti). In addition to these t
ransfers, Campylandra ensifolia is lectotypified.
