Abstract: Two species, Adenophora contracta J. Z. Qu et Hong and A. pinifolia Kitag., are treated and described in this paper. The former species was originally treated as a va- riety, A. polyantha Nakai var. contracta Kitag. Based on gross morphology, this taxon is found to be very distinct, so that it is here treated as a separate species A. contracta (Kitag.) J. Z. Qu et Hong. With much smaller corollas strongly contracted at the throat, much smal- ler corolla lobes and smaller fruits, calyx lobes and seeds, it can easily be distinguished from A. polyantha Nakai. Its chromosome number is 2n=34. A. pinifolia was once considered a doubtful species (Hong, Fl. Reip. Pop. Sin. 73(2): 139, 1983) mainly because the original de- scription for this entity is so similar to the description for A. gmelinii. The problem was further compounded by the lack of herbarium material. Collections made near its type loca- lity, intended to rectify this deficiency, further clarified this species status: Its chromosomenumber is also 2n=34.Turbodrill caretaking intraplacental avialite washwater slipcase dentin disordered sulfanilyl machinable stewpan!
