Mexican mountain pines

Pinus montezumae / P. pseudostrobus group

Useful plants

Stylized form diagram for Mexican mountain pines

Identify: Long needles in bundles, large cones and thick bark; species vary with elevation.
Habitat: Mexican and Central American pine-oak highlands.
Season: Year-round wood; seeds seasonal.
Field use: Poles, resinous kindling, fuel and edible pine seeds from selected species; pitch aids repairs.
Caution: Species identification and protected-forest rules matter. Cones and dead limbs fall.
Look-alikes: Cloud-forest firs have flat needles and upright cones.

Oaks

Quercus spp.

Useful plants

Identify: Alternate leaves; acorns in cups; buds clustered at twig tips. Leaf lobes may be rounded or bristle-tipped.
Habitat: Temperate woodland, savanna, Mediterranean scrub and mountain forest.
Season: Acorns fall; wood year-round.
Field use: Dense bow and handle wood, durable stakes and excellent coals. Acorns are high-energy food only after species-specific leaching to remove tannins.
Caution: Never eat raw bitter acorns in quantity. Moldy acorns are unsafe.
Look-alikes: Chestnuts have spiny burs and long toothed leaves.

Alders

Alnus spp.

Useful plants

Identify: Oval toothed leaves; catkins; woody cone-like female structures persist through winter.
Habitat: Wet thickets, streambanks, avalanche tracks and disturbed forest.
Season: Wood year-round; leaves growing season.
Field use: Straight stems for racks and wattle; seasoned alder burns evenly and is widely used as smoking wood.

Guadua bamboo

Guadua angustifolia and related spp.

Useful plants

Identify: Large hollow segmented culms; branch thorns in some species; broad grass leaves.
Habitat: Tropical American riverbanks, foothills and disturbed forest.
Season: Culms year-round; shoots rainy season.
Field use: Exceptional material for shelter, containers, water tubes, traps, arrow shafts, bows in laminated designs and friction-fire sets; young shoots of selected species require boiling.
Caution: Fresh culms can split explosively in fire. Species and shoot cyanide levels vary.
Look-alikes: Woody reeds are smaller and lack robust branching culms.

Agaves

Agave spp.

Useful plants

Identify: Thick fibrous succulent leaves with a terminal spine; giant branched flower stalk produced after years.
Habitat: Hot deserts, dry slopes and thorn scrub of the Americas.
Season: Roasted hearts and stalks seasonal; leaves year-round.
Field use: Prepared leaf fiber makes cordage and nets; dry stalk makes fire-drill and construction material; traditionally roasted hearts of selected species are food.
Caution: Raw sap and leaf juice can cause severe dermatitis. Harvesting kills the plant and may be illegal.
Look-alikes: Yuccas have thinner leaves and bell flowers; aloes have softer gel-filled leaves.

Habitat: Dry Americas, disturbed warm regions and some Mediterranean/African landscapes.
Season: Fruit summer-fall; young pads seasonal.
Field use: Ripe fruit and properly de-spined young pads of confirmed species are documented foods; dry woody joints can support fuel.
Caution: Invisible glochids embed in skin, eyes and mouth. Some fruits are insipid or seedy; avoid sprayed invasive stands.
Look-alikes: Chollas have cylindrical joints.

Aquatic edibles

Water-margin food species

Cattails

Typha spp.

Water and wetland edible plants

Identify: Tall flat strap leaves; dense brown cylindrical female flower spike below a narrower male section.
Habitat: Marshes, pond edges, slow channels and wet ditches.
Season: Shoots spring; pollen early summer; rhizomes year-round where lawful.
Field use: Documented food parts include young inner shoots, pollen and processed rhizome starch. Leaves make mats, baskets and thatch; seed down can bulk tinder.
Caution: Water can concentrate sewage, metals and parasites. Raw rhizome requires correct processing; avoid contaminated marshes.
Look-alikes: Yellow flag iris has sword leaves and showy flowers but no brown cattail head.
