. Plant studies; an elementary botany. Botany. 356 PLAiNT STUDIES 2oG. Conifers.—Tliis is tlio great modern (iymnospcrm group, ami is cliaractoristic of the temperate regions, where it forms great forests.

The habit of the body is quite charac- teristic, a central shaft ex- tending continuously to the very top, while the lateral branches spread horizontal- ly, with diminishing length to the top, forming a coni- cal outline (Figs. 50, 57). This habit of firs, pines, etc., gives them an appear- ance very distinct from that of other trees. Anotlier peculiar feature is furnished by the char- acteristic " needle-leaves," which seem to be jx'orly adapted for foliage. These leaves have small spread of surface and very heavy pro- tecting walls, and show adap- tation for enduring hard conditions (Kig. 308). As they have no regular period of falling, the trees are always clothed with them, and have btn-n catlcil " evergreens." 'i'hert! are some notable exce])tions to this, however, a,s in the case of th(! eomnion larch or laniarack, whicii sheds its leaves every season (i''ig. 5(i)..
