caption_attribution_description: English&#x3a;&#32; Monochoria vaginalis is a species of flowering plant in the Water hyacinth family known by several common names, including Heartleaf false pickerelweed and Oval-leafed pondweed. It is native to much of Asia and across many of the Pacific Islands, and it is known in other areas as an introduced species and often an invasive noxious weed. An aquatic plant, it is invasive in rice paddies and other water bodies. This is an annual or perennial herb growing in water from a small rhizome. It is quite variable in morphology. The shiny green leaves are up to about 12 centimeters long and 10 wide and are borne on rigid, hollow petioles. The inflorescence bears 3 to 25 flowers which open underwater and all around the same time. Each has six purple-blue tepals just over a centimeter long. The fruit is a capsule about a centimeter long which contains many tiny winged seeds.മലയാളം&#160;&#x3a;&#32; ചതുപ്പ് പ്രദേശങ്ങളിൽ കാണപ്പെടുന്ന ഒരു ഔഷധസസ്യമാണ്‌ കരിങ്കൂവളം. കുവലയം എന്നാണ് ഇതിന്‌ സംസ്കൃതത്തിൽ അറിയപ്പെടുന്നത്. ഇന്ദീവര, നീലോല്പല എന്നിങ്ങനെ സംസ്കൃതത്തിലും നീലോല്പൽ എന്ന് ഹിന്ദിയിലും ഈ ചെടി അറിയപ്പെടുന്നു. നീളമുള്ള തണ്ടിൽ ഒരു ഇലയായിരിക്കും ഉണ്ടാകുക. ഇലകൾ ചെറുതും അറ്റം കൂർത്തതുമായിരിക്കും. ഇളം നീലകലർന്ന നിറമുള്ള മൂന്നോ നാലോ പൂക്കൾ നീളമുള്ള തണ്ടിൽ ഒരുസമയം ഉണ്ടാകാറുണ്ട്. വിത്തുകൾ ഒരു ഫലത്തിനുള്ളിൽ ഒന്നിലധികം കാണപ്പെടുന്നു. ചെടിക്ക് മധുര രസവും ഗുരുവും സ്നിഗ്ദ്ധവുമായ ഗുണവും ശീതവീര്യവും മധുര വിപാകവുമാണുള്ളത്. ഏറ്റവും ഔഷധമൂല്യമുള്ള ഭാഗം വേരും ഇലകളുമാണ്‌. പിത്തം, പൊള്ളൽ, പനി, സ്കർവി തുടങ്ങിയ അസുഖങ്ങൾക്ക് ഉപയോഗിക്കുന്നു.
context_page_description: Pontederiaceae is a family of flowering plants.
  The APG IV system of 2016 places the family in the order Commelinales, in the commelinid clade, in the monocots. It is a small family of heterostylous aquatic plants, occurring in tropical and subtropical waters. Charles Darwin was interested in the specialized form of heterostyly found in the family, known as tristyly. Not all of the species are heterostylous. The family contains two genera with around 40 known species.
  It is best known for the water hyacinth, which is an invasive species in many waterways. The highly modified Heteranthera gardneri is a submerged aquatic with a two-flowered pseudanthium.

  The APG IV system of 2016 (unchanged from the APG III system of 2009, the APG II system of 2003 and the APG system of 1998) places the family in the order Commelinales, in the commelinid clade, in the monocots. It is a small family of heterostylous aquatic plants, occurring in tropical and subtropical waters.

  It is best known for the water hyacinth (Pontederia crassipes), which is an invasive species in many waterways. The highly modified Heteranthera gardneri is a submerged aquatic with a two-flowered pseudanthium.
