STUDIES IN SEEDS AND FRUITS 



{25) Leucana glauca, p. 326. — See p. 334. 



(26) Lonicera Periclymenum^ p. 325. — See p. 266. 



(27) Mauritia setigera, p. 326. — See below under Palms. 



{28) Momordica Charantia, p. 325. — The arils are included in the 

 weight of the pericarp. Their proportion is shown below 

 where the drying regime of a fruit is given. 



(29) Momtera pertusa, p. 326. — Most berries have one seed, but quite 



10 per cent, have two seeds. 



(30) Opuntia Tuna, p. 325 See Note 10, B, on p. 478. 



(31) Oreodoxa regia, p. 326. — The small shrinkage of the fruit is due 



to the large quantity of oil in the pericarp. 



(32) Palms. 



{a) Areca Catechu, pp. 26, 326. — There is reason for believing 

 that, as in the Coco-nut, the seed reaches maturity after 

 the pericarp has begun to dry. 



{b) Arenga saccharifera, p. 325. — The fruit is characterised as a 

 drupe in the table, but the data there given are based on 

 the view that it is a berry, and so I will take it. The 

 pericarp-proportion is much reduced in 3-seeded fruits, as 

 compared with I -seeded fruits. Thus : — ■

(d) The tribe Cocoineie. — The drying regime and the proportion of 

 parts are represented in the following table for the drup- 

 aceous fruits of palms of this tribe.
