of small flowers; ovary i-celled, with a single ovule. Glohularia. 

 (Pf. IV, 3b, 270.) 



Family 186. Acanthaceae. Herbs (shrubs and trees) with op- 

 posite leaves ; ovary 2-celled ; placentae axile ; seeds 2 to many 

 without endosperm. Thnnhcrgia, Rncllia, Acanthus, Jnsticia. 

 (Pf. IV, 3b, 274.) 



Order Lamiales. Corolla mostly irregular or oblique ; sta- 

 mens fewer than the corolla-lobes, usually 4 or 2 : ovules mostly 

 solitary ; fruit indehiscent. 



Family 187. Myporaceae. Shrubs and trees, with usually al- 

 ternate leaves; flowers axillary. Myopornm. (Pf. IV, 3b, 354.) 



Family 188. Phrymaceae. Erect, perennial herbs, with oppo- 

 site leaves, and small spicate flowers ; calyx and corolla cylin- 

 drical, 2-lipped ; stamens 4; ovary i-celled, i-ovuled. Phr\nia. 

 (Pf. IV,'3b, 361.) 



Family 189. Verbenaceae. Herbs, shrubs, and trees, with usu-

 petals separate, and with the stamens inserted on the calyx or the

 higher, families. This subclass originates near the beginning of 

 the Thalamiflorae, and indeed the orders Ranales and Rosales are 

 unquestionably closely related. 



Order Rosales. Flowers usually perfect, regular or irregular ; 

 pistils separate or more or less united, sometimes united with the 

 calyx-tube ; styles usually distinct. 



Family 191. Rosaceae. Herbs, shrubs, and trees with mostly
