Injections of oxy·tetra·cycline HCl (“H-C-L”) protect these plants from being affected by phytoplasma-induced (“FYE-toe-plaz-muh-induced”) lethal yellowing. These plants’ apical growth only occurs at a meristem-rich core above the crownshaft called the “heart.” They’re not ferns, but dried-out tissue left over after these plants have shedded their leaf-like structures is often retooled as (-5[1])pseudobark. Since these trees cannot form cambium, they are the only trees not to display growth rings. The tallest (-5[1])non-bamboo (*) monocot plants comprise mainly of these kinds of (-5[1])trees. The “de mer” species of (10[1])these trees is (10[1])responsible for generating the largest plant seeds and can be found in the Seychelles (“say-SHELZ”). For 10 points, name these fronded (10[1])tropical (-5[2])trees noted for their production of dates and coconuts. (10[5]) ■END■
