Beaucarnea recurvata, the elephant's foot [4] or ponytail palm, [5] is a species of flowering plant in the family Asparagaceae. The species was native to numerous states of eastern Mexico but is now confined to the state of Veracruz. [1] [6] Despite its common name, it is not closely related to the true palms .
The ferns (Polypodiopsida or Polypodiophyta) are a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers.They differ from mosses by being vascular, i.e., having specialized tissues that conduct water and nutrients, and in having life cycles in which the branched sporophyte is the dominant phase.
Pteridospermatophyta, also called "pteridosperms" or "seed ferns" are a polyphyletic [1] grouping of extinct seed-producing plants. The earliest fossil evidence for plants of this type are the lyginopterids of late Devonian age. [ 2 ]
Historically both lycophytes and monilophytes were grouped together as pteridophytes (ferns and fern allies) on the basis of being spore-bearing ("seed-free"). In Smith's molecular phylogenetic study the ferns are characterised by lateral root origin in the endodermis , usually mesarch protoxylem in shoots, a pseudoendospore, plasmodial tapetum ...
The forehead of the elephant is actually a structure that protects the pollen from the weather called a galea, and ranges in size from 1.5–3 millimeters, and extends into the long slightly coiled beak that resembles the elephant's trunk of 5–18 millimeters; the lateral lobes of the flower resemble an elephant's ears. This "remarkable ...
