DICOTYLEDONES. 



Pollination essentially the same as the preceding order. 320 species ; es- 

 pecially in N. Am. Some are useful on account of their edible fruits, especially 

 Vaccinium myrtillus and V. vitis-idaa, and in a less degree Oxycoccus, etc. 

 The fruits of V. myrtillus are officinal. 



FIG. 546. Vaccinium uliginosum (var. micropTiyllum). The parts of the flower A-E are 

 enlarged 5-6 times ; C and E are longitudinal sections ; B and D the flower seen 

 from above ; F and G a stamen seen irom the back and front ; H the style and 

 stigma. 



Family 27. Diospyrinse. 



The flowers are regular, gamopetalous, typically diplostemonous, 

 with the same number throughout all 5 whorls, thus : Sn, Pn, 

 An + n, Gn, where n most frequently = 5 (4-6), rarely 3, 7 or 8. 

 Of the two whorls of stamens the one opposite the sepals is often 

 present only as rudiments or is entirely suppressed, and the com- 

 pletely developed stamens are thus placed opposite the petals. The 

 carpels are generally placed opposite the sepals. The ovary is 

 multilocular with the ovules attached in. the inner angles. The 

 fruit is most frequently a berry. The seeds are large, generally 

 solitary, or a few in each loculus. -AH plants belonging to this 

 family are trees or shrubs with scattered, single, 'most frequently 

 entire, penninerved and leathery leaves without stipules ; the ma- 

 jority are tropical (America, Asia), some are found in N. Am. and 

 the Mediterranean. 



Order 1. Sapotaceae. Plants with latex; anthers extrorse, 1 erect ovule 

 in each loculus ; fruit a berry ; the seeds with bony, shiny brown testa have a 

 large, lateral hilum. The leaves are frequently covered with silky hairs. A
