The outer surface glabrous; have inner bracts obovate to spathulate, greyish and concave. The outer surface of the plant has short white hairs on the distal abaxial surface. [8] The flower heads of the plant species are 3–6 mm long, 3.5–5.5 mm wide. [10] Eriocaulon produces new leaves outwards from the central crown. [11]
Whilst L. birnbaumii itself is harmless to plants the sclerotia can have economic impacts on the production and sale of Orchids which often have transparent root pots where the sclerotia can collect. Their presence in these containers can reduce the aesthetic value of the plants and have impacts on the water retention of the substrate. [37]
In wet soils, their abundance appears to be related to water levels, fire frequency, and competition from other plants such as grasses. Experiments have shown that they are weak competitors compared to many other wetland plant species. [6] Some species can persist as buried seeds during unfavorable conditions. [7]
Monotropa uniflora, also known as ghost plant, ghost pipe, or Indian pipe, is an herbaceous, parasitic, non-photosynthesizing, perennial flowering plant native to temperate regions of Asia, North America, and northern South America, but with large gaps between areas.
The plant produces rosettes of leaves and an inflorescence on a long rigid scape. The leaves are extremely variable, from 10–50 cm (4– 19 + 1 ⁄ 2 in) in length [10] and 1 to 2 cm (1 ⁄ 2 to 3 ⁄ 4 in) thin to wedge-shaped like those of S. cuneata. Spongy and solid, the leaves have parallel venation meeting in the
To ensure adequate humidity, the plant pot should be placed in a larger container with constantly moist peat and sprayed with water daily. Dusty leaves should be wiped clean with a damp cloth. Feed in the summer with a small dose of fertilizers dissolved in water. After a few years of cultivation, the plant becomes unattractive, where its ...

The market prices for betel leaves vary with the wet and dry seasons in Sri Lanka, and in 2010 averaged SL Rs. 200–400 per 1,000 leaves ($1.82 to $3.64 per 1000 leaves). [41] The FAO study assumes no losses from erratic weather and no losses during storage and transportation of perishable betel leaves. These losses are usually between 35% and ...
