     31<h2>California conifers</h2>
     32
    3333Throughout California's Sierra Nevada mountains,
    3434and especially at high altitudes,
    35 the dominant plants are tall, straight
    36 trees with narrow needle-like leaves.
    37 These trees are called <b>conifers</b>
    38 because they carry their seeds in cones.
    39 <p>
     35the dominant plants are tall, straight trees called <b>conifers</b>.
     36Conifers are remarkable in many ways:
     37<ul>
     38<li> They have existed in approximately their current form
     39for 240 million years.
     40<li>
     41They display remarkable tenacity and adaptibility,
     42managing to grow in the most unlikely places:

     45<li> The largest living thing is a conifer:
     46the General Sherman, a Giant Sequoia in Sequoia National Park.
     47Its trunk volume is 52,500 cubic feet.

     49<li>
     50The oldest known living thing is a conifer:
     51a 4,500-year-old bristlecone pine in the White Mountains
     52(a mountain range that neighbors the Sierra Nevada).
