CLASSIFICATION. 



granular masses (pollinia) in each anther cell. Pollinia of 

 the right hand cell cf each anther united by a caudicle to a 

 gland (corpuscle) to which is also attached the pollinia of the 

 left-hand cell of the adjacent anther. Fruit always of 2 

 free or connate follicles and seeds winged or comose. Fila- 

 ments usually connate in a column round the pistil- 



75. AsclepiadaceaB (p. 4.30). 

 Order V.— Personales. 



Shrubs or herbs, rarely trees, occasionally glandular and 

 aromatic, with alt. or opp. exstipalate simple or compound 

 leaves. Fls. usually zygomorphic (regular in most Solanacese, 

 and sub-regular in the perianth in several genera of other 

 families), but not contorted in bud. The posticous stamen 

 nearly always rudimentary or altogether absent (perfect in 

 Solanaceas), sometimes only 2 stamens perfect. Ovary 5- 

 celled superior with many ovules. Fruit capsular, or baccate. 



Exceptions : — 



Solanacese on account of the regular flowers is usually included in 

 Polemoniales, but certain genera show zygomorphic flowers (not in Chota 

 Nagpur), and the ovary is that of Personales. 



Oroxylum (Bignoniaceas) has 5 perfect stamens. 



Ovary is 1-celled in Orobanchacese, Lentibulariace© (little marsh 

 plants common in rice fields), Gesneraoese (herbs of moist banks), and 

 Martynia. 



Ovary is 4-celled in Datura and by a false septum in some Pedalia- 

 ceae. 



Acanthaceas has- often only 2 or few ovules in each cell. 



76. The Potato Family. 



Shrubs or herbs with alternate simple, rarely deeply 

 lobed or (Tomato) pinnate leaves Fls. regular in cymes. 

 Sep., pet., and stamens 5. Ovary with 2 oblique carpels and 

 2 swollen axile placentas covered with ovules. Fr. a berry 



or capsule. 76. Solanaceae (p. 438).
