upon the criteria adopted. It is useless asking which is the better or more 
natural position. 
Series XXXVI. Rhamnatles 
173 Rhamnacez”: Nearest akin to the Rhamnaces are the Vitaces ; 
after which come the Celastracee. They are also compared with the Oli- 
niacess (Myrtifloree) by BarLLon. 
174 Vitacese”: ‘In floral structure these come quite close to the Rham- 
nacese. Another closely related family which may be pointed out next to 
the Rhamnacex, is that of the Umbelliferee, perhaps more closely allied to 
the Vitacese, if we put aside the difference in the relative position of petals 
and-stamens. 
Series XXXVIL. Malvatles 
175 Eleeocarpacese”: Intimately connected with the Tiliacew. The 
family is also related to the Flacourtiaces, as can be seen in a comparison of 
Prockia and Hasseltia.® It is, therefore, regarded by some authors, as a family 
intermediate between the Malvales and the Parietales. 
178 Chlenacee®”: Dr Canpotze refers this family to the Malvales. 
Barton places it near the Theaces or even assigns it to the latter family. It 
‘is nearer to the Tiliaces than to the Malvales, in so far as the constant dithe- 
cous stamens are concerned. It is also comparable with the Dipterocarpacese. 
177 Gonystylacee”: [Related to the Tiliacess in its anatomical and 
morphological characters. 
178 Tiliacese”: Connected with the Malvacex, Sterculiacese and Chlee- 
naces of the Malvales. Also with the Theacew, Dipterocarpacec, Bixaceze 
and Flacourtiacee of the Parietales. 
179 Malvaceew”: These stand quite near the Bombacacex, Sterculiacess 
and Tiliaces. But, in the hairy seeds, in the curved embryo and in the 
secondary meristem in the xylem, they are closely related to the Convolvulaces.
