. Hypericum perforatum, also known as St John’s wort, is a flowering plant species in the genus Hypericum and a medicinal herb that is sold over-the-counter as a treatment for depression.[1][2] Other names for it include Tipton’s weed, rosin rose, goatweed, chase-devil, or Klamath weed.[1] Hypericum perforatum is a yellow-flowering, stoloniferous or sarmentose, perennial herb indigenous to Europe. It has been introduced to many temperate areas of the world and grows wild in many meadows.
The herb’s common name comes from its traditional flowering and harvesting on St John‘s day, 24 June. The genus name Hypericum is derived from the Greek words hyper (above) and eikon (picture), in reference to the plant’s traditional use in warding off evil by hanging plants over a religious icon in the house during St John’s day. The species name perforatum refers to the presence of small oil glands in the leaves that look like windows, which can be seen when they are held against the light.[1]
St John’s wort is a perennial plant with extensive, creeping rhizomes. Its stems are erect, branched in the upper section, and can grow to 1 m high. It has opposing, stalkless, narrow, oblong leaves that are 12 mm long or slightly larger. The leaves are yellow-green in color, with transparent dots throughout the tissue and occasionally with a few black dots on the lower surface.[1] Leaves exhibit obvious translucent dots when held up to the light, giving them a ‘perforated’ appearance, hence the plant’s Latin name.
Its flowers measure up to 2.5 cm across, have five petals, and are colored bright yellow with conspicuous black dots. The flowers appear in broad cymes at the ends of the upper branches, between late spring and early to mid summer. The sepals are pointed, with glandular dots in the tissue. There are many stamens, which are united at the base into three bundles. The pollen grains are ellipsoidal.[1]
When flower buds (not the flowers themselves) or seed pods are crushed, a reddish/purple liquid is produced.

Interestingly I find the plant uploaded at FOI as this species is a member of Ranunculaceae, perhaps Caltha palustris. Note several spirally arranged achenes in that photo. Thnaks for showing the leaf structure Sir Ji The photographs at FOI have now been replaced by mine. Thanks … for quick action.

Seen in a park in the Niagara Falls area growing wild. End of June,17.
Could be Hypericum perforatum? Just a guess. Look at Saint John’s Wort aka Hypericum perforatum. Thanks for validating the id suggested by me.  I’d requested 30: 1 high res. image.
Location: Rajouri j and k Hypericum sp . No habitat and other images? Seems Hypericum
H. perforatum seems reasonable guess. .
I think ID is correct. Also called Saint John’s wort is the source of the drug Hypericin.
The leaf if held against a light source e.g. sun will appear to be full of minute translucent dots(glandular tissue) looking like pores.
It is used in herbal medicine as an antibiotic and in Chinese medicine as an antidepressant.
