inferior ovary, parietal placenta and exalbuminate seeds. Consequuetly, some 

 of the Helobiae are certainly connected with the Liliifloroe, some with the 

 Fariuosse, some with the Spathiflorse, some with the Ranales, some with the 

 Triuridales, and some with the Microsparmae. The natural position of the 

 series is, therefore, not necessarily settled as between the Paudanales and the 

 Glumiflorse. It should be placed here at one time, but there at another. 



Next to the Helobise, ENGLER refers to the Triuridales^ in his syllabus. 

 But, it is rather questionable whether the series belongs to the Mouocotyledones 

 or the Dicolytedones. On one hand, as has been pointed out before, it is 

 somewhat related to the Helobise, but on the other hand, to the Microspermae, 

 as can be seen in a comparison of the Triuridacese with the Orchidacese. 



Then, he treats of the Glurniflorae' . But, decidedly, this series also is 

 not to be definitely placed between the Helobioe and Priucipes in the true 

 natural system. It has some connection with the Liliiflorae through the 

 Juncace33 3) in its vegetative orgaus 4) and in its external form ; and also with 

 the Fariuosae, as can be seen in the external relation between the Cyperaceae 

 .and the Eriocaulacese^. Its natural position should be changed according to 

 different views. 



The next series'" placed by ENGLER are the following three : Principss, 

 Syuanthae and Spathiflorre. They by no means stand in a serial relation, but 

 rather in a close inter-relation between themselves and also in relation with 

 other series. The first series is somewhat allied to the Paudauales, as we 

 have above stated. To some extent they approach the Syuanthse, as the 

 -Cyclauthaceae of the latter series have an incontestable similarity to the Pahme 7) 

 in the vegetative organs. The second series is related to the Paudauales and 

 Principes, as we have seen before. At the same time, the resemblance in the 

 vegetative organs of the Cyclaiithaceae and those of the Aracea3' s) indicates that 

 the Syuanthae and Spathiflorse are related. The relations of the latter series 

 to the Paudauales, to the Sjnianthse and to the Helobite have been already
