Context paragraphs:
Parnassius tenedius: Parnassius tenedius, the tenedius Apollo, is an east Palearctic member of the snow Apollo genus ("Parnassius") of the swallowtail family (Papilionidae).  Populations range from Siberia and the Far East of Russia to the western Chukchi Peninsula, Mongolia and north China.  The larva feeds on "Corydalis" species.  In the northern part of its range it is a low altitude butterfly; further south it is montane.

Myosotis: Myosotis ( ; from the Greek: μυοσωτίς "mouse's ear", after the leaf) is a genus of flowering plants in the family Boraginaceae.  In the northern hemisphere they are commonly called forget-me-nots or scorpion grasses.  The common name "forget-me-not" was calqued from the German "Vergissmeinnicht ", and first used in English in 1398 AD via King Henry IV.  Similar names and variations are found in many languages. " Myosotis alpestris" is the state flower of Alaska and Dalsland Sweden.  Plants of this genus are commonly confused with Chatham Islands forget-me-nots which belong to a related genus, "Myosotidium".

Corydalis chelidoniifolia: Corydalis chelidoniifolia (Fern-leaf Corydalis) is a flowering plant in the genus "Corydalis".

Myosotidium: Myosotidium is a genus of plants belonging to the family Boraginaceae.  This genus is represented by the single species Myosotidium hortensia, the giant forget-me-not or Chatham Islands forget-me-not, which is endemic to the Chatham Islands, New Zealand.  The biogeography is yet unresolved, but its ancestors are likely from the American continent, as "Myosotidium hortensia" was found to be sister to the South American plant genus "Selkirkia" and both genera being sister to the North American genus "Mimophytum".

Corydalis flexuosa: Corydalis flexuosa is a species of flowering plant in the genus "Corydalis", of the Papaveraceae family.  It is a shade-loving perennial originating in woodland and mountainous areas of China.  Growing to 30 cm , in spring it produces masses of bright blue tubular flowers with a white throat.  It is summer dormant, meaning that the foliage dies down in summer.

Capnoides: Capnoides sempervirens, the harlequin corydalis, rock harlequin, pale corydalis or pink corydalis, is an annual or biennial plant native to rocky woodland and burned or disturbed places in northern North America.  Capnoides sempervirens is the only species in the genus Capnoides.

Parnassius nordmanni: Parnassius nordmanni is a high altitude butterfly which is found the Caucasus.  It is a member of the snow Apollo genus (Parnassius) of the swallowtail (Papilionidae) family.  The larva feeds on "Corydalis" species including "C. alpestris", "C. conorhiza" and "C. emanueli".

Corydalis yanhusuo: Corydalis yanhusuo is a species of genus "Corydalis".  Research has indicated that the alkaloid dehydrocorybulbine (DHCB), extracted from the roots of the plant, can be helpful in reducing neuropathic pain.  Tetrahydropalmatine is a major constituent alkaloid which also has analgesic activity.

Pseudofumaria: Pseudofumaria is a genus of herbaceous perennial plants native to Europe, formerly included in the genus "Corydalis".

Corydalis: 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.
