MALVACEÆ. 103 
In Pachira the same habit and foliage is to be observed, together 
with large fine flowers having an entire truncate calyx and a long 
thick coriaceous corolla ; but the five bundles of stamens, often rather 
indistinct at the base, are each formed of a large number of pieces, 
with slender filaments and one-celled anthers, straight or simply 
arched. Moreover, their capsular fruit has not the seeds surrounded 
by the thick layer of cotton, to the centre of which they were plunged 
in the preceding genera. All the Pachiras are American. A dozen 
to fifteen species of them may be enumerated. 
The Baobabs or Adansonias (figs. 169, 170) are very similar to the 
preceding genera, the flowers being almost the same, with a large 
Adansonia digitata,

malvaceous corolla; but their calyx is quinquefid, and the fruit dry, 
woody, and indehiscent. The numerous seeds are enveloped in an 
abundant acidulous pulp, which finally dries and becomes farinaceous. 
The two known species of this genus, one Australian and the 
other widely spread in the warm regions of Asia and Africa, are trees 
whose trunks attain gigantic proportions in diameter, their digitate 
leaves having from three to nine entire folioles. The flowers are 
axillary and solitary, and hang from the summit of their peduncle,
