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 pseudobark. Since these trees cannot form cambium, they are the only trees not to display growth (10[1])rings. The tallest non-bamboo (*) monocot plants comprise mainly of these kinds of trees. The “de mer” species of these trees is responsible for generating the largest plant seeds and can be found in the (-5[1])Seychelles (“say-SHELZ”). For 10 points, name these fronded tropical trees noted for (10[1]-5[1])their production of dates and (10[1])coconuts. ■END■
