Question: Of Corydalis and Water dropwort, which one grows in higher altitudes?
Context: Oxypolis filiformis is a species of flowering plant in the carrot family known by the common names water cowbane and water dropwort.  It grows in swamps, freshwater wetlands, and along the borders of ponds in the southeastern United States, as far north as Delaware, as well as the northern Bahamian pineyards of the Bahamas. Daphne bholua, the Nepalese paper plant, is a species of flowering shrub in the genus "Daphne" of the family Thymelaeaceae.  It grows at altitudes of 1700 - in the Himalayas and neighbouring mountain ranges, from Nepal to southern China.  At lower altitudes it is found as an evergreen in thickets and forest margins; at higher altitudes, it is deciduous and is usually found in pastures and grassy glades.  It usually reaches a height of about 2.5 m , though some specimens reach 4 m or more. Corydalis (Greek "korydalís" "crested lark") is a genus of about 470 species of annual and perennial herbaceous plants in the Papaveraceae family, native to the temperate Northern Hemisphere and the high mountains of tropical eastern Africa.  They are most diverse in China and the Himalayas, with at least 357 species in China. The water dropworts, Oenanthe , are a genus of plants in the family Apiaceae.  Most of the species grow in damp ground, in marshes or in water. Nabak-kimchi (나박김치 ) is a watery kimchi, similar to "dongchimi", in Korean cuisine.  It is made of thinly sliced Korean radish and napa cabbage (called "baechu", hangul 배추, in Korean) into a rectangular shape as main ingredients and salted them with mixed vegetables and spices such as cucumber, scallion, water dropwort (called ""minari"", 미나리 in Korean), garlic, ginger, red chilies, chili pepper powder, sugar, salt, and water. Celaque National Park (formally in Spanish, Parque Nacional Montaña de Celaque) is a national park in Lempira Ocotepeque and Copán, western Honduras.  It was established on 5 August 1987 and covers an area of 266.31 square kilometres.  It includes Honduras’ tallest peak, called Cerro Las Minas or Pico Celaque, which reaches approximately 2870 m above mean sea level.  It has an elevation ranging from 975 to .  Celaque’s terrain is very rugged, two-thirds of the area has a slope greater than 60 degrees.  The park is classified as a cloud forest with a mean precipitation of 1,600 mm at lower altitudes and a mean of 2,400 mm at higher altitudes.  The word "celaque" is reputed to mean "caja de aguas" ("box of water(s)") in the local, but now extinct, indigenous Lenca language.  Celaque’s nine rivers supplies water to 120 villages nearby including the district capital of Gracias.  Celaque is high in biodiversity and is home to pumas, ocelots and Bolitoglossa celaque, an endangered plethodontid salamander found only in the mountains of Celaque. High-altitude cooking is the opposite of pressure cooking in that the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure.  This may require an increase in cooking times or temperature and alterations of recipe ingredients.  For home cooking, this effect becomes relevant at altitudes above approximately 2,000 feet (610 m).  At that altitude, water boils at approximately 208°F (98°C) and adjustments sometimes need to be made to compensate for the reduced air pressure/water boiling point. Dracophyllum recurvum is a prostrate to semi-erect shrub belonging to the genus "Dracophyllum".  It is distinguishable from other species in the genus by its thin, recurved leaves.  "D. recurvum" grows in subalpine and alpine environments in the volcanic Central Plateau of the North Island of New Zealand, being especially plentiful on Mount Ruapehu and the other mountains of Tongariro National Park.  "D. recurvum" is one of the few plant species that can survive the extreme conditions on Ruapehu, due to its wide-spreading root system, which firmly anchors the plant to the thin soil, as well as helping halt erosion on the mountain.  "D. recurvum" grows up to one metre high at lower altitudes, or down to less than five centimetres at higher altitudes.  The plant's branches are covered in a greyish bark, and its leaves vary from dark green at lower altitudes to reds and greys at higher altitudes.  Leaves are 10 - in length and usually approximately 2 mm wide.  The physical characteristics of "D. recurvum" vary greatly with changes in altitude. Oenanthe javanica, commonly Java waterdropwort, Chinese celery, Indian pennywort, water celery and water dropwort, is a plant of the water dropwort genus originating from East Asia.  (Chinese celery is also the name given to "Apium graveolens" var.  "secalinum").  It has a widespread native distribution in temperate Asia and tropical Asia, and is also native to Queensland, Australia. Cicutoxin is a poisonous polyyne and alcohol found in various plants, such as the highly toxic water hemlock ("Cicuta" species).  It is a natural product structurally related to the oenanthotoxin of hemlock water dropwort.
