Have been described, but, in the absence of a recent revision of the genus, it is difficult to say how many of these may be valid. Adenophora is widely spread over temperate and parts of subtropical Asia, one species, A. liliifolia (L.) Fisch., reaching as far west as eastern Germany and Hungary. The subject of this plate is from the eastern end of the range of the genus, being a native of the island of Formosa, just within the tropics, where A. morrisonensis Hayata and A. verticillata Fisch. are probably the only representatives of the genus. Variable, as are many members of the genus, A. morrisonensis is not a very well-defined species, as some of its forms closely approach the widespread A. polymorpha Ledeb. The plant which is here figured differs in certain respects from the specimen on which A. morrisonensis is based, but the writer has no doubt that our plant is a form of that species. The chief points of difference are the.
