remote relation is to be found between the Taccacea3 and the Iridacese in the 

 form of the stigmata, on the one hand, and on the other, between the former 

 family and the Dioscoreaceae in the undivided ovarj. Moreover, there exists 

 some resemblance in the Taccacese and Bm-manniacese. 



38 DioscoreaceaB ^^ .' Very clearly relatedto the Liliacese, especially to 

 the Smilacoideae of the latter family. Another connection is to be found 

 between this family and the Taccacese or Amaiyllidacese. 



39 Iridaceae ^^ : These resemble the Hsemodoraceae in the single whorl of 

 the androeceum, though the latter are represented by the outer whorl in the 

 Iiidaceae, while by the inner whorl in the Hsemodoracese. The Morseeae of the 

 Iridaceae approach the Taccacese in the shape of their stigmata.

40 Musaceae^^ .' The coincidence in the floral structure in the Musaceae 

 and Orchidaceae is the most precise conceivable in the comparison of orchida- 

 ceous flowers and Lowia and Orclddaniha both of which show their Hps 

 directed downwards by resupination. 



41 Zinglberaceae : As above. 



42 Cannaceae : As above. 



43 Marantaceae ^^ : These are nearest the Cannacese ; wliile the latter 

 are rehited to the Zingiberaceae. The four famihes of the Scitaminese are con- 

 nected at one point or another.

44 Burmanniaceae^'^ : Some relations seem to exist between this family 

 and the Orchidacea^, and also between it andthe AmaryUidacese. 



45 Orchidaceae*'^ : This family is near the Burmanniacese and the 

 Tiimidacege. It agrees to some extent with the Musaceae, Zingiberacese 

 and Marantaceae in its imperfect staminal whorls. The diagram of Musa is 

 in accoi-dance with that of Arundina pentandra.
