STUDIES IN SEEDS AND FRUITS 



(25) Leuccena glauca, p. 326. — See p. 334. 



(26) Lon'icera Periclymenum^ p. 325. — See p. 266. 



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



(28) Motnordica Charantia, p. 325.^ — The arils are included in the 



weight of the pericarp. Their proportion is shown below 

 where the drying rt^gime of a fruit is given. 



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



10 per cent, have two seeds. 



(30) Opuntia Tuna^ p. 325. — See Note lO, 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 : — 



Moist fruit, i-seeded, pericarp-proportion go per cent. 



„ 3-seeded, „ „ 69 „ 



Dry fruit, i-seeded, „ „ 80 „ 



„ 3-seeded, „ „ 55 „ 



would seem that the seed 

 the pericarp has begun 



(<•) Mauritia setigera^ p. 326. — It 

 continues to ripen after 

 to dry. 



{d) The tribe Cocoineee. — The drying regime and the proportion of 

 parts are represented in the following table for the drup- 

 aceous fruits of palms of this tribe. 

 Explanatory remarks follow.
