Digitaria horizontalis

NAME: Digitaria horizontalis

FAMILY: Poaceae (Grass family)

COMMON NAMES: Creeping crabgrass, Summer grass

LOCAL NAMES: Shama grass (India), Tokouso (West Africa)

MORPHOLOGICAL DESCRIPTION: Digitaria horizontalis, commonly known as creeping crabgrass, is a warm-season annual grass that spreads by creeping stolons. It typically grows in dense mats with wiry, thin stems that can reach up to 50 centimeters in height. The leaves are slender, linear, and arranged alternately along the stem. The inflorescence consists of numerous tiny spikelets arranged in branched, digitate clusters. The spikelets contain small, grain-like seeds.

USEFUL PART(s): The entire plant, including the leaves, stems, and seeds, can have various uses.

GENERAL USES:

  1. Forage: Digitaria horizontalis is often used as forage for livestock due to its high nutritional content. It provides a valuable source of food for grazing animals.

  2. Erosion control: The dense mat-like growth of creeping crabgrass helps stabilize soil and prevent erosion in areas with disturbed or bare soil.

  3. Lawn grass: In some regions, creeping crabgrass is cultivated as a lawn grass due to its ability to tolerate heat and drought conditions.

  4. Medicinal uses: In traditional medicine, some cultures use Digitaria horizontalis for its purported medicinal properties, such as in the treatment of digestive disorders and skin ailments.

GEOGRAPHIC DISTRIBUTION: Digitaria horizontalis is native to tropical and subtropical regions, and it has a wide distribution across different continents. It can be found in parts of Africa, Asia, the Americas, and Australia. It thrives in warm and humid environments, often growing in disturbed areas, cultivated fields, lawns, and along roadsides.

WHY IS IT GREEN? Like other plants, Digitaria horizontalis appears green due to the presence of chlorophyll in its cells. Chlorophyll is a pigment that plays a vital role in photosynthesis, the process by which plants convert sunlight into energy to fuel their growth. Chlorophyll molecules absorb light from the red and blue regions of the electromagnetic spectrum and reflect green light, giving plants their characteristic green color.

ENVIRONMENTAL IMPACT:

  1. Invasive potential: Digitaria horizontalis can sometimes become invasive, spreading rapidly and outcompeting native plant species. It can colonize disturbed areas, agricultural fields, and gardens, reducing biodiversity and affecting ecosystem dynamics.

  2. Weed pressure: Creeping crabgrass can be a problematic weed in lawns and agricultural fields, as it competes with desired plants for resources such as nutrients, water, and sunlight.

  3. Erosion control: On the positive side, Digitaria horizontalis can contribute to erosion control by stabilizing soil with its dense mat-like growth, particularly in areas prone to soil erosion.

FUN FACT:

Digitaria horizontalis is known as "crabgrass" due to its habit of growing low to the ground and spreading horizontally, resembling the creeping movement of crabs. Despite its reputation as a weed, creeping crabgrass has adapted to survive in diverse environments and has found useful applications in different cultures around the world.

Delonix regia

NAME: Delonix regia

FAMILY NAME: Leguminosae

COMMON NAMES: Flame of the forest, Red Flame, Phoenix tree, Royal Poinciana, Flame Tree, Poinciana, Flamboyant Tree

LOCAL NAMES: Seke seke, ayin.

MORPHOLOGY: Delonix regia is a conspicuous, fast growing almost evergreen legume tree that can be 10-30 m in height and is shallow-rooted. Tree can shed its leaves in areas with a marked dry season. The bole is sometimes relatively short. The trunk may reach 2 m in girth and it can be buttressed towards the base. The bark is smooth, sometimes slightly cracked, with lenticels. The crown is umbrella-shaped, broadly spreading its long horizontal branches. The overall tree is thus larger in diameter than in height. The twigs are stout, greenish, finely hairy when young becoming brown. The leaves are bipinnate, alternate, feathery, 20-60 cm long, bearing 10-25 pairs of pinnae, each with 30-60 opposite leaflets. The leaflets are 0.5-1 cm long, stalkless, minutely hairy on both sides. The inflorescences are slightly fragrant corymbs borne laterally at the end of the twigs. The inflorescence bears large (5-13 cm), magnificent flowers, orange-red in colour, loosely arranged on 5-7.5 cm long stalks. The 4 clawed-petals are spoon-like in shape and the 5 sepals are thick, green in color, finely hairy. The fruit is a 30-75 cm long pod, It is green and flaccid when young, turning to brown and woody at maturity. The pods remain on the tree after it has shed its leaves. The 30-45 seeds contained in the pods are hard, greyish, mottled, oblong in shape, looking like date pits. They are hardcoated. The taxon name Delonix regia is after the greek "delos" meaning visible and "onyx" meaning claw and the latin "regia" meaning royal, magnificent. Most of the common names for Delonix regia (see Common names) are derived from the colour of its flowers

PART(S): Leaves, bark, seeds, flowers

GENERAL USES: It is an outstanding flowering tree for gardens, parks, along streets, and for large front yards. Mature trees provide excellent shade

GEOGRAPHICAL DISTRIBUTION: Madagascar, Isreal, USA, Mauritus, Brazil, Peru, Paraguay, Egypt, Iran, Jordan, Cyprus, Spain Lebenon, India, Indonesia, Thailand, Philippines, China, Australia, Taiwan

WHY IS IT GREEN: Diuretic, anthelmintics, astringent, leucorrhoea

ENVIRONMENTAL IMPACT: The leaves and flowers have been reported to have herbicide effects on Mikania micrantha, an invasive climber. The wood ash of Delonix regia could significantly reduce several fungi and insects.

It serves as shade tree, Delonix regia is helpful in maintaining soil moisture and reducing soil temperature. Flamboyants have been planted on eroded sites for erosion control, and for soil rehabilitation

The flamboyant is a N-fixing legume that can improve soil N status. Leaf and green stem prunings applied to a calcareous soil for 5 years resulted in improvement of 13% in N and higher organic C and mineralization

FUN FACT: The tree has been known to collapse without warning.

There is a popular belief among Saint Thomas Christians of Kerala that when Jesus was crucified, there was a small royal poinciana tree nearby his Cross. It is believed that the blood of Jesus Christ was shed over the flowers of the tree and this is how the flowers of royal poinciana got a sharp red color.

COMMON NAMES: Flat bean

LOCAL NAMES: Ogundu, Paran, runhun zaki, Obunzizi

MORPHOLOGY: Dalbergia saxatilis is usually a vigorous climbing shrub producing stems up to 20 metres long, though sometimes it remains smaller, growing as a shrub only 2 - 3 metres tall. The stem is usually up to 5cm in diameter near the base, but can occasionally reach 15cm. The branches are very tortuous, with some of them modified as woody spine hooks
