	Lemnaceae - Wikipedia, the free encyclopedia
		Lemnaceae is a botanical name for a family of flowering plants.
		Such a family has been recognized by most systems of plant classification, but it is not recognized by the APG II system: this refers the plants involved to family Araceae, the aroid family.
		Lemnaceae in Watson, L. and M.J. Dallwitz (1992 onwards).

		The distribution maps of the Lemnaceae show the area where the species once was collected and do not represent the actual distribution area, which might be considerably smaller and change within a few years.
		Wolffia fronds are eaten as a vegetable in southeastern Asia; Lemna gibba is cultivated in Israel for use as a vegetable and salad.
		Lemnaceae are also used for waste-water purification and as test and indicator plants.

	Duckweed
		The Lemnaceae family, known commonly as Duckweed, is considered to be the smallest and structurally simple of all angiosperms (Waynes World, 1999).
		The Lemnaceae's reproductive cycle, physiology, and even the evolution of individual species, are directly related to the duration of insolation they receive.
		They are monocotyledons belonging to the botanical family Lemnaceae and are classified as higher plants, or macrophytes, although they are often mistaken for algae..

		Duckweeds (family Lemnaceae) comprise a distinctive group of diminutive, aquatic monocotyledons which have been difficult taxonomically because of their cosmopolitan distribution, extreme reduction and miniaturization.
		As currently circumscribed, the Lemnaceae comprise 38 species in five genera which include the world's smallest angiosperms.
		As a consequence, Lemnaceae are now among the most thoroughly understood angiosperm families from a systematic standpoint.

		Reveal (1997) and Thorne (1997) submerge both the Pistiaceae and the Lemnaceae into the Araceae as the latest data suggest the families are well embedded in the Araceae.
		As noted previously, the Lemnaceae do not appear to represent a unique family, and it is with considerable reluctance (and sadness) that I have reduced the family to synonymy under Araceae.
		Members of the Lemnaceae have considerable economic importance as a source of green fertilizer in many under-developed and developing nations where great masses are grown in sewage ponds and then added to fields.

		The Lemnaceae are the structurally simplest of the flowering plants.
		The plants are not differentiated into stems and leaves; instead, the plants in the family have an undifferentiated leaf-like body commonly referred to as a frond or thallus.
		Plants usually with 2 to several roots on the lower side of the fronds; under surface of the frond usually reddish; nerves 3 to 15 and usually distinct

		Members of the genus Wolffia of the family Lemnaceae are the smallest flowering plants in the world.
		Although the Lemnaceae are members of the Division Anthophyta (flowering plants) they rarely flower in nature and rely instead on budding (asexual) reproduction.

	Modeling duckweed growth in wastewater treatment systems
		Because flowering in Lemnaceae is rare, reproduction normally occurs by budding from mature fronds.
		A population of duckweed is actually a population of individual fronds (leaves) that can reproduce and divide to produce daughter fronds.
