vessels, in the hairy covering, and in the structure of the stomata, it shows 
its relations to the Labiate. Bar~ion places this family near the Solanaces. 
Series XLIX. Rubiales 
275 Rubiacee”: Certainly closely related to the Caprifoliacese and also 
to the Valerianacese, Dipsacacese and Composite. But in the cruciate opposite 
leaves, in the capitate inflorescence, and in the floral structure, this family is 
closely allied to the Cornacess; some of the Rubiacew are very near some of 
the Umbelliferee in the structure of the fruit. In some particular cases, it 
shows some connection with the Loganiacese and Bignoniacex. 
276 Caprifoliaceee”: Intimately allied to the Rubiacex ; also very near 
the Cornacese and to the Valerianaces. 
277 Adoxacese”: Somewhat comparable with the Araliacess and Saxi- 
fragaces. Also with the Caprifoliaces. 
278 Valerianacese”: Very near the Dipsacacess and the Caprifoliaces. 
279 Dipsacaceer”: Undoubtedly related to the Valerianacex, especially 
to Triplostegia of the latter family. amnion points out the existence of some 
resemblance between this family and the Calyceracem. 
Series L. Cucurbitales 
280 Cucurbitacer™: Near the Passifloracese, Caricacess, Campanulacex, 
Loasacese and Begoniaces, as has been explained above. 
Series LI. Campanulate 
281 Campanulacee”: This family is related to the Goodeniacew and 
Candolleacess through the Lobelioidess. It also comes close to the Composite 
in the connation of the anthers, in the isostemony, in the nearly (with ex- 
ceptions) epigynous insertion and in the valvate wstivation of the corolla-lobes. 
The inflorescence of many campanulaceous genera is similar to that of the
