258 Verbeiiacese^ : Related to the Scrophulariacese, Phrymacese and 

 Convolvulaceae. The bon-aginaceous genera with the terminal styles and 

 aetinoniorphous flowers are very much like the Verbenacese. The Solanacene 

 with few ovules are closely connected with the Verbeuacere. 



259 Labiatae ' : The relation of this family to the Borragiuacese is seen 

 in the eremus- formation. It is also connected with the Scrophulariacese, 

 Acauthacepe and Verbenacese. BAILLOX points out that the Borraginacese 

 imply plants with terminal styles as well as those with gynobasic ones, wliile 

 the Labiates and Verbenacese are each made a family, by the fact of its 

 having terminal styles or gyuobasic ones. Such a classification is altogether 

 inconsistent. In any case, the separation of the latter two families is purely 

 subjective 3 *. 



260 Nolanacese 4) : This family is undeniably related to the Convolvu- 

 lacese, Borraginaceae, and Solanacea?. Its connection with the Couvolvulaceae is 

 to be found in the corolla, and in the 3-5-carpelled ovary. Its resemblance t< > 

 the Borraginaceae exists in the peculiar fruit -formation. It is most closely re- 

 lated to the Solanaceie in the aestivation of the corolla, in the ramification of 

 the stems, in the foliar arrangement, and in the structure of the seeds. 



261 Solanaceae 5) : Morphologically speaking, this is a very heterogene- 

 ous family. It includes several forms transitional between the families of the 

 Tubiflorae with actinomorphous flowers and those with zygomorphous flowers. 

 The Solaneae and Nicaudreae with regular flowers approach the families of the 

 former category ; while the Cestreae and Salpiglossideae pass so gradually int.' 

 the Scrophulariaceee (a family of the latter category), that it is quite artificial 

 to draw a Hue between these tribes of the Solanaceae and the Scrophulariaceae. 

 A revision of the genera of the Solanaceae shows us clearly that these genera 

 bear close relations to several different families respectively. 



262 Scroph.ulariaceae 0) : Tliis has such close relations to many other 

 families that it is rather a difficult task to limit the family. The Scrophularia-
