It is distinguished from other water crowfoots by a lack of submerged capillary leaves, all leaves being shiny, ivy shaped with 3-5 shallow lobes, broadest at the base and sometimes darker in the centre. Ivy-leaved crowfoot grows in mineral waters whereas the similar-looking round-leaved crowfoot is "invariably" found in more peaty waters.
Chorizema cordatum is an erect, scrambling or climbing shrub that typically grows up to 1 m (3 ft 3 in) high and 1.5 m (4 ft 11 in) wide. Its leaves are heart-shaped, 30–50 mm (1.2–2.0 in) long with a stipule at the base of the petiole, and often have wavy, toothed or lobed edges.
Temperature Extremes. The ideal temperature range for a prayer plant is between 60 to 80 degrees Fahrenheit, says Langelo. Any temperature that is lower or higher can cause the leaves to curl.
It has cordate (heart-shaped), sometimes triangular leaves 25 to 75 mm long. The flowers are borne in panicles, clustered along the rachis. Producing pink or white flowers from spring to autumn, it forms underground tubers and large rootstocks. It is a prolific seed producer. The seeds float on water.
As the leaves develop, they become increasingly distorted, and ultimately thick and rubbery compared to normal leaves. The color of the leaves changes from the normal green to red and purple, until a whitish bloom covers each leaf. Finally, the dead leaf may dry and turn black before it is cast off. Changes in the bark are less noticeable, if ...
Depending on the specimen, leaf shape varies from heart-shaped to long and arrow-shaped, usually with 2-3 angled lobes on each side, resembling the juvenile leaves of ivy (Hedera). Leaf color varies from all-green to all-silver, but the most common is a Christmas tree or hastate pattern in silver or pewter and various shades of green.
Glechoma hederacea can be identified by its round to reniform (kidney- or fan-shaped), crenate (with round-toothed edges) opposed leaves2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) diameter, on 3–6 cm (1 + 1 ⁄ 4 – 2 + 1 ⁄ 4 in) long petioles attached to square stems that root at the nodes.
Hedera nepalensis (Himalayan ivy, chang chun teng) is a species of perennial Ivy (genus Hedera) native to Nepal and Bhutan, as well as Afghanistan, Pakistan, India, China, Laos, Myanmar, Thailand, and Vietnam, at altitudes of about 1000–3000 m. Plants grow up to 30 m in height, with simple leaves ranging from 2–15 cm long, and yellow flowers.
