On the basis of morphorogy, it is very difficult to classify some plants in the Liparis species of Orchidaceae. We have examined the possibility of chemotaxonomical classification in several plants of the Liparis species. From our observation, it is clear that some Liparis species of the Orchidaceae

β¦ Synopsis
In the previous paper (l), we reported the structure of Nervosine which was isolated from Liparis nervosa Lindl.. We further studied two plants, Liparis Kurameri French. et. Sav." and Liparis Kumokiri F. Maekawa**, both of which are Liparis species of the Orchidaceae

AN earlier examination' of the alkaloids of Stemmadenia species led to the isolation of (+)-quebrachamine, a number of Iboga-type bases2 and a new alkaloid named stemmadenine (C2, H26\_28N203). The latter has also recently been en-countered3 in Diplorrhynchus condylocarpon together with a second new
