GUTTIFER^E 233 



Moronobeae and wanting or very minute in the Garcinieee. 

 The radicle is always inferior, and in the Calophylleae it is very 

 short with large cotyledons sometimes grown together in a 

 mass. In Quiina they are large and fleshy but distinct, while 

 the radicle is very short. 



Seedlings. In the seedlings observed the cotyledons where 

 present are subterranean in germination, and this generally 

 obtains where seeds are large, exalbuminous, and contain a 

 fleshy embryo. The cotyledons of Calophyllum Inophyllum 

 (fig. 209) occupy a large globular seed, and their fleshy petioles 

 are just long enough to allow the plumule to get clear out 

 of the seed. They are also subterranean. The first pair 

 of leaves are reduced to scales, as are also generally the second 

 pair, or these are imperfectly developed. Then follow two pairs 

 of narrowly elliptical, obtuse leaves, after which the seedling 

 stops growing for the season. The penninerved venation is 

 remarkable on account of the dense arrangement of the veins 

 in parallel lines. 



Xanthochymus pictorius (fig. 208) and Mesua ferrea agree 

 with the above in all general particulars ; but in the former 

 the first four pairs of leaves are reduced to small, ovate, 

 or subulate, black scales, and only one pair of lanceolate 

 acuminate leaves are produced in the first year. The veins 

 of the leaves are parallel but wider apart than in Calo- 

 phyllum. In Mesua ferrea the first four pairs of leaves are 

 small, scaly, and caducous, followed by two pairs of lanceolate- 

 oblong very finely penninerved leaves, after which growth 

 ceases for a time. When growth recommences the terminal 

 bud is blind, and two axillary branches are developed bearing 

 a single pair of narrower, oblong leaves, and again terminate 

 in a blind bud. The branching is therefore strictly cymose 

 from a very early stage, that is, from the end of the first 

 year's growth of the seedling. 



Xanthochymus pictorius, Roxb. (fig. 208). 



Primary root long, stout, fleshy, yellowish, giving rise to a few 

 strong adventitious roots near the upper end. 



Hypocotyl short and merging into the root, subterranean. 



Cotyledons subterranean, large, fleshy, filling the large seed and 

 not leaving the testa.
