Palm Trees Introduction:
The Palm tree (Palmaceae) have been termed the princes of the vegetable kingdom. Neither the anatomy of the Palm tree stems nor the conformation of their flowers, however, entitles them to any such high position in the vegetable hierarchy.
Palm tree stems are not more complicated in structure than those of the common butcher broom (Ruscus); their flowers are for the most part as simple as those of a rush (Juncus). The order Palmaceae is characterized among monocotyledonous plants by the presence of an unbranched stem bearing a tuft of leaves at the extremity only, or with the leaves scattered; these leaves, often gigantic in size, being usually firm in texture and branching in a pinnate or palmate fashion.
The flowers are borne on simple or branching spikes, very generally protected by a spathe or spathes, and each consists typically of a perianth of six greenish, somewhat inconspicuous segments in two rows, with six stamens, or pistil of 1-3 carpel's, each with a single ovule and a succulent or dry fruit. The seed consists almost exclusively of endosperm, Upper portion of Coconut seed, albumen in a cavity in showing the embryo, embedded in endosperm, which is lodged the relatively very minute embryo. T
hese are the general characteristics by which this very well-defined order may be discriminated, but, in a group containing considerably more than a thousand species, deviations from the general plan of structure occur with some frequency. As the characteristic appearances of palms depend to a large extent upon these modifications, some of the more important among them may briefly be noticed.
