Besides these are the sandalwood, Santalum, of southern India, and many sorts of bamboo found in all parts of the country.
Sandalwood (Santalum album or freycinetianum) was once abundant on rugged and rather inaccessible heights, but so great a demand arose for it in China,' where it was used for incense and for the manufacture of fancy articles, that the supply was nearly exhausted between 1802 and 1836; since then some young trees have sprung up, but the number is relatively small.
It is different from the white fragrant sandal-wood, which is the produce of Santalum album, a tree belonging to a distinct natural order Santalaceae.
This embryo-sac increases in size, gradually supplanting the cellular tissue of the nucellus until it is surrounded only by a thin layer of it; or it may actually extend at the apex beyond it, as in Phaseolus and Alsine media; or it may pass into the micropyle, as in Santalum.
