268 Verbenaceae''' : Related t» the ScroplaulariacesB, PhrjTnacese and 

 Convolvulacese. Tlie borraginaceous genera with the terminal styles and 

 actinomorphous flowers are very much like the Verbenacese. The Solanaceae 

 witli few ovules are closely connected with the Verbenacese. 



259 Labiatae'^ : Tlie relation of this family to the Borraginacese is seen 

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

 Acanthaceae and Verbenaceae. Baillon points out tliat the Borraginaceae 

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

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

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

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

 subjective^\ 



260 Nolanaceae*^: This family is imdeniabty related to the Convolvu- 

 lacese, Borraginacese, and Solanacese. Its comiection with the Convolvulaceae is 

 to be foimd in the corolla, and in the 3-5-carpelled ovary. Its resemblance to 

 the Borraginacese exists in the pecuHar fruit-formation, It is most closely re- 

 lated to the Solanacese in the sestivation of the corolla, in the ramification of 

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



261 Solanaceae^^: Morphologically sijeaking, this is a very heterogene- 

 ous family. It inchides several forms transitional between the famiUes of the 

 Tubiflorse with actinomorphous flowers and those with zygomorphous flowem. 

 The Solanese and Nicandrese with regular flowers approach the famihes of thfr 

 former category ; while the Cestreae and Salpiglossideae jxass so gi-adually into 

 the Scrophulaiiacese (a family of the latter category), that it is quite artificifil 

 to draw a line between these tribes of the Solanacese and the Scrophulariacege. 

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

 bear close relations to several different families respectively. 



262 Scroph.ularlaceae''^: Tliis lias such close relatious to mau}' other 

 famihes that it is rather a difficult task to Hmit the family. Tlie Scrophularia-
