Relation to Architecture
ANAHAW
DEFINITION
Saribus rotundifolius is a round-leaf fountain palm found in Southeast Asia. It is a member of the genus Saribus. It is also called Footstool palm (English) and as Anáhaw or Luyong (Filipino). The foliage of the Saribus rotundifolius is the unofficial national leaf of the Philippines.
CULTIVATION

Typically, anahaw occurs beneath the canopy of dipterocarp and mixed species forest. It is normally scattered in forests at low to medium altitudes. It also grows on brushlands and under coconut plantations.

It is one of the fastest growing palms in the world widely cultivated in tropical, subtropical park and gardens. It is a useful and tolerant plant that does not require any special care. A seedling can turn into a 15-20 cm trunking specimen palm in only 3 years if given fertilizer and sufficient water. It is also quite tolerant of being dug up and moved.
SOWING

The folk technology involves two steps: (1) sow freshly depulped seeds evenly on previously prepared seedbeds; (2) press the seeds lightly in the seedbeds and cover them with soil; and, (3) cover the seedbeds with coconut leaves, cut grass or other mulching materials. Germination starts approximately 1 month after sowing.

HARVESTING

Poles and Stems
The poles/stems are harvested et the age of 14-16 years (about 10-12 m tall and 20-25 cm in diameter). It has a natural durability period of 8 years. Poles are usually transported by trucks, with an average of 110 stems measuring 10-12 m long and 20-25 cm in diameter per truck.

Leaves
Two to three leaves can be harvested per tree per month. Spaced at 2m x 2m, a hectare of land can accommodate 2,500 plants with a corresponding yield of R18,000/year with a conservative price of PO.30/leaf

Saribus is a genus of 1 species of palms (family Arecaceae), native to Southeast Asia. They are fan palms, the leaves with an armed petiole terminating in a rounded, costapalmate fan of numerous leaflets.
GENUS:

saribus
Binomial name:

Saribus rotundifolius
Anahaw or anahau is an erect palm reaching a height of 15 to 20 m and 25 cm in diameter. The trunk is smooth, straight, and marked with close, rather shallow obscure rings which are the leaf scars. The leaves are crowded at the top of the trunk and ascending. The green, smooth, flattened petiole may have hard, black spines. The circular, fan shaped, pleated leaf blades are 1 m in diameter and divided into segments 2.5 to 4 cm wide. The green flowers are 2 mm long. The fruit is 1.5 cm in diameter, fleshy and yellow with a hard, round, brown seed inside.
DISTRIBUTION
The species is endemic to the Philippines and most commonly found in Luzon (Benguet, La Union, Cagayan, commonly found in Luzon (Benguet, La Union, Cagayan, Pangasinan, Zambales, Pampanga, Laguna, Ouezon, Camarines, Albay), Negros, Cagayan de Oro and in the provinces of Mindanao.

USES
Anahaw is often planted as an ornamental plant for indoor and outdoor as it remains bright green even in very dry environment. The trunk is hard, strong and durable. It can be split into strips for flooring, siding and even handles of tools. It is commonly used as posts, piles in fishpen and poles. The buds and shoots are cooked as a vegetable. Mature leaves are used as roofing of houses in rural areas. The leaves last up to 15 years when properly used. The young leaves are made into raincoats, hats, fans and containers for rice, charcoal, etc.

Seed Collection
The best time to collect Anahaw fruits is when they are orange in color and still in the branchlets. Fallen fruits are prone to decay and fungi attack. Anahaw fruits can be collected by climbing and chipping off the branchlet using an extension pruner or a pole with a scythe

Seed Extraction
Place the newly collected fruits in clean sacks and store under a shade or inside the room for 3 to 5 days to loosen the pulp. Fruits stored this way easily ripen. After 5 days, the fruits are macerated by putting them in a basin of water to soften the pulp.
Remove the decayed pulp to extract the seeds. Immediately after depulping, soak the clean seeds in water to minimize loss of moisture. Sow the seeds on the same day.

Soil
: It is suited for fertile, loamy substrates, but it is adaptable to many kinds of well-drained soils, including clay; sand; alkaline or acidic.

Fertilization
: Need a perfect fertilizer diet including all micro nutrients and trace elements or slow release fertilizer applied during the growing season, or according to package directions, using a fertilizer specifically formulated for palms
.
Water Requirements
: It prefers evenly moist but not consistently wet medium. Plants should be watered during dry spells and will benefit from an organic mulch. It dislikes soggy soils.
Light
: It prefers bright sunny locations, but it also does well in part shade with some direct sunlight, young specimens should be partially shaded. It will also survive in rather heavy shade but "stretches" to lose its compact shape.

Wind resistance
: It is fairly resistant to breakage but avoid strong wind.

Hardiness
: It is cultivable only in tropical and subtropical climates, as it does not stand temperatures close to the zero, but for a very short period. ( ZONES: 10B, 11
)
Roots
: Usually not a problem
Maintenance:
The lower leaves which turn brown as the plant grows need to be removed from the plant, but do not prune if the frond still has some green colour. Palms recycle nutrients from dead or dying fronds and use them for healthier fronds

Pest and diseases:
It is generally a pest free plant. It could however be attacked by mealybugs and scales. It is also moderately vulnerable to lethal yellowing disease.

Uses:
It is used massively in gardening and landscaping in many parts of the world. Its neat form makes it ideal for staggered groupings, street, parking lot island, sidewalk, highway median or used as a free-standing specimen. They form a closed canopy when planted about 3 m apart along a walk or street. They can thrive in harsh urban conditions. It is also excellent in containers and urns. It also tolerates shady spots and young plants are often utilized in pot for inner spaces decoration. It can adapt itself better than many other plants to the indoor conditions of our homes and buildings. It can also tolerate some amount of neglect.

Traditional uses:
The leaves are used for thatching and food-wrapping.
Propagation:
Fresh seeds if kept warm germinate readily within 2 months of sowing.
