First leaves compound, abruptly pinnate, petiolate, alternate,

Germination. The radicle emerges at the dorsal suture of the 

 fruit, or breaks through the side walls. It fixes itself in the 

 ground, and the lengthening hypocotyl generally carries the 

 lomentum and seed up with it. All the coverings, however, 

 finally drop off, leaving the seedling free. Where the radicle 

 pierces the sides of the lomentum the latter is fixed to the soil. 

 The cotyledons on becoming free are ovate-oblong, obtuse, 

 subfalcate, or rounded on the upper edge and with a shallow 

 sinus on the lower edge, subfleshy, pale yellowish-green, shining, 

 glabrous.
