Cycas pectinata – Fern Palm
Cycas pectinata is a species of cycad, commonly known as Fern Palm. It is a group of ancient seed plants that have existed since the time of the dinosaurs. Often referred to as "living fossils," cycads like Cycas pectinata are prized for their unique appearance, slow growth, and evolutionary significance. Native to parts of South and Southeast Asia, this species is one of the larger and more striking cycads, both in natural habitats and botanical gardens.
The Fern Palm, is a medium to large-sized cycad. It typically grows as a solitary trunked plant that may reach up to 10 meters (33 ft) tall in mature specimens. The trunk is cylindrical and covered with persistent leaf bases. Its leaves are pinnate (feather-like), dark green, and can grow up to 3 meters long, giving the plant a palm-like appearance.
The leaflets are narrow and arranged in a distinct comb-like pattern, which gives the species its name — “pectinata” meaning “comb-like.” New leaves often emerge with a bronze or reddish tint, gradually turning green as they mature.
Fern Palm is found in the subtropical and tropical forests of northeastern India, Bhutan, Nepal, Bangladesh, northern Myanmar, northern Thailand, Laos, and parts of southern China. It typically grows on slopes, rocky hillsides, or in open forest areas, often at elevations between 300 and 1,200 meters above sea level.
Like all cycads, Cycas pectinata is dioecious, meaning male and female reproductive organs occur on separate plants. Males produce cone-like structures called microstrobili, while females bear megasporophylls, which are modified leaves bearing ovules. Pollination is usually facilitated by wind or insects. After fertilization, large seeds are produced, which may take several months to mature. Germination is slow, and seedlings grow very gradually, sometimes taking years to develop a recognizable trunk.
Cycads play an important role in forest ecosystems, including nitrogen fixation through symbiotic relationships with cyanobacteria in their roots. In some traditional cultures, cycads are used for ornamental purposes, religious ceremonies, and even food — though seeds must be carefully processed to remove toxins.
Due to its striking appearance and historical significance, Cycas pectinata is cultivated in tropical and subtropical gardens around the world. It prefers well-drained soil, partial shade, and protection from frost. However, care must be taken when growing cycads, as many species contain toxic compounds and should be handled with care, especially around pets and children.
Cycas pectinata is a remarkable species that connects the present-day flora with the prehistoric world. Its majestic form, resilience, and rarity make it a plant of both scientific interest and ornamental value. Preserving this species in its natural habitat and through sustainable cultivation is essential to maintaining the biodiversity of ancient plant lineages. While Fern Palm is not currently classified as endangered, it faces threats from habitat destruction, deforestation, and illegal collection for ornamental and horticultural purposes. In many regions, wild populations are in decline. Conservation efforts include habitat protection, regulation of trade, and propagation in botanical gardens and nurseries.

Acer rubrum – Red Maple
Acer rubrum commonly known as Red Maple also known as swamp Maple or Soft Maple is native to Eastern and Central North America. Red maple is one of the best named of all trees. It is generally easy to identify for its highly changeable in morphological characteristics.
Red Maple is a medium to large growing tree is growing 18 – 27 m (60 – 90 ft) in height, but exceptionally grows over 35 m (116 ft) in height. It is spread is about 12 m (40 ft) with a rounded to oval crown. The trunk diameter can range 46-76 cm (18-30 in), depending on the growing conditions. It is a slow growing tree, within 10 years it may grow about 6 m (20 ft) tall. It grows faster than Norway Maples and Sugar Maples, but slower than Silver Maple.
A. rubrum is a deciduous tree. The leaves are green in color and turned into red in autumn but can also become yellow or orange on some of leaves. They are typically 5 – 10 cm (2 – 4 in) long and same as wide, with 3 – 5 palmate lobes with a serrated margin. The sinuses are typically narrow, but the leaves can display important variation. The top side of the leaves are light green and the down side is whitish and can be either sea-blue or hairy. The leaf stalks are up to 10 cm (4 in) long and usually red in color.
The twigs are reddish in color and partially shiny with small lenticels. Midget shoots are present on many branches. The buds are normally blunt and greenish to reddish in color, usually with several loose scales. The lateral buds are slightly stalked and in addition there may be collateral buds present as well. The buds form in fall and winter and are often visible from a distance due to their reddish tint.
The flowers of Red Maple are appear in spring generally coming before the new leaves. The flowers usually unisexual, with male and female flowers blooming in individual sessile clusters, although sometimes they are also bisexual. The considered Polygamodioecious by itself that meaning some flowers individuals are male, some are female, and some flowers are monoecious. For the Climate condition, the Red Maple tree sometimes can change from male to female or male to hermaphroditic, or hermaphroditic to female. The tree usually start blooming when it grow about 8 years old but it significantly varies between tree to tree some trees star blooming when 4 years old. The flowers are red in color, with 5 small petals and 5 lobed calyx borne in hanging clusters, usually at the twig tips. They are lineal to oblong in shape with pubescent. The feminine flowers have one pistil formed from two fused carpels with a glabrous superior ovary and two long styles that protrude beyond the calyx. The staminate flowers contain 4 – 12 stamens, sometime with 8.

The fruit is a samara 1.5 – 2.5 cm in long that grows in pairs with somewhat divergent wings at an angle of 50 to 60 degrees.  They are borne on long slender stems and are variable in color from light brown to reddish. They ripen from April through early June, before even the leaf development is altogether complete. After they reach maturity, the seeds are dispersed for a 1 to 2 week period from April through July.
The bark of young trees is smooth, silvery-gray becoming scaly and dark with age and older branches and trunk are covered with scaly gray brown bark.
Red maple is a wonderful ornamental tree for its attractive foliage. It is cultivate as ornamental tree in the urban road side and park.
