CLASSIFICATION. 



The Pomegranate Family (included in LythracesB in the body of 

 the flora) differs from Myrtacese in the leaf venation, in the ovary having 

 the cells arranged in two whork and in some of the ovules having axile 

 placentation. The calyx has usually 6 (5-8) sepals as in LythraceaB, but 

 the ovary is quite adnate to the hypanthium. Frnit a berry with many 

 cells and seeds. 



Punicaceae (p. 351). 



45. The Henna Family. 



Trees, shrubs or herbs with often 4-angled branches, 

 leaves rarely gland-dotted. Fls. regular l(zygomorphous in 

 Woodfordia), perigynous. Sepals 3-6, often 6, valvate with 

 sometimes intermediate smaller ones. Petals isomerous 

 with the sepals (on the long petaloid hypanthium in Wood- 

 fordia) sometimes minute or 0. St. diplostemonous (2-8 in 

 Ammannia) or very many, on the hypanthium which is long 

 or very short. Ovary free from the hypanthium 2-6 celled. 

 Ovules very many. 45. Lythraceae (p. 354). 



46. The Evening Primrose Family. 



Herbs, sometimes aquatic. L. opp. or alternate. Fls. 

 regular or slightly zygoraorp'hous. Seps. and petals 4 (4-6 in 

 Tussiea). St. 4 or 8. Ovary 2-4-celled adnate]to the hypan- 

 thium (only half inferior in Trapa). Ovules many (solitary 

 in each cell in Trapa). Seeds many (1 in Trapa). 



46. Onagraceaa (p. 356). 



47. The Melastoma Family- 



Shrubs or herbs with opposite leaves characterized by 

 sub-parallel primary nerves and usually parallel cross sec. 

 nerves. Fls. usually handsome, regular or slightly zygomor- 

 phous in the androecium. Anthers opening by pores. 

 Ovary united to the hypanthium by vertical wall*.

48. The Mangrove Family. 



Trees or shrubs with opp. glabrous leaves and interpetio- 

 lar stipules. Fls. small greenish 5-8-merous. Petals and st. 

 inserted on an outer disc lining the hypanthium which is
