To other monocotyledonous families the resemblances are merely of adaptive or vegetative characters.
CYPERACEAE, in botany, a natural order of the monocotyledonous group of seed-bearing plants.
Elodea is a member of the monocotyledonous natural order Hydrocharideae.
Comparing the flower of Gramineae with the general monocotyledonous plan as represented by Liliaceae and other families (fig.
Some of the fossils referred to the genus Kaidocarpon, and originally described as monocotyledonous inflorescences, are undoubted Araucarian cones; other cones of the same type have been placed in the genus Cycadeostrobus and referred to Cycads.
It would appear, then, that the orchid flower differs from the more general monocotyledonous type in the irregularity of the perianth, in the suppression of five out of six stamens, and in the union of the one stamen and the stigmas.
The earliest Angiosperm yet found in Europe is a single monocotyledonous leaf of doubtful affinities, named by Saporta Alismacites primaevus (fig.
The flower has in rare cases a perianth of six scale-like leaves arranged in two whorls, and thus conforming to the common monocotyledonous type of flower.
The number of species of orchids is greater than that of any other monocotyledonous order - not even excepting grasses - amounting to 6000, contained in 400 genera.
In monocotyledonous plants there is only one seed-leaf or cotyledon, and hence the arrangement is at first alternate; and it generally continues so more or less, rarely being verticillate.
