Agave funkiana K.Koch & C.D.Bouché
Funk's Agave
Agave funkiana, locally known as maguey henequén del norte or northern lecheguilla, is a medium-sized species native to the states of Tamaulipas and San Luis Potosí in northeastern Mexico. It is characterised by its long, narrow, intense green leaves with fine but sharp marginal teeth and a terminal spine that can exceed 5 cm. It has historically been exploited for coarse fibre extraction, similar to henequén (Agave fourcroydes), from which ropes, sacks, and crafts were made in rural communities of northeastern Mexico. It is a species adapted to the Tamaulipan thornscrub, one of the most arid and biodiverse ecosystems in northeastern Mexico.

| Conservation Status | Least Concern (LC) – IUCN. Common in Tamaulipan thornscrub although its habitat faces agricultural and livestock pressure. |
| pH Target | 7.0–8.5 |
| Type | Sandy, stony or calcareous caliche, highly draining |
Origin & Habitat
Morphology
Linear-lanceolate, rigid, 50–90 cm long and 3–6 cm wide, intense to dark green. Margin with small reddish-brown corneous teeth, spaced 1–3 cm apart, and a prominent terminal spine 4–6 cm long, dark brown to black.
ecoYellow to reddish, 5–8 cm, arranged in panicles on a scape 4–6 m tall. Flowering occurs only once, typically at 10–20 years. Flowers are visited mainly by bats and nocturnal moths.
ecoAcaulescent or with a very short, compact stem. The numerous narrow leaves produce good-strength fibre, though of lower quality than true henequén (A. fourcroydes). The plant accumulates sugars in the piña at a moderate rate.
ecoShallow and well-distributed root system, adapted to the sandy-stony substrate of Tamaulipan thornscrub. Fine, branched roots penetrate cracks in calcareous caliche to anchor the plant.

Propagation Strategy
P
P
Every 3–4 years; prefers in-ground planting for best development.
Annual spring fertilization with slow-release mineral fertilizer, low in nitrogen (5-10-10). No fertilization in autumn or winter.
Uses & Applications
Precautions / Toxicity
Low to moderate. The terminal spine is very hazardous and can cause deep wounds. Avoid placing in high-traffic gardens or areas accessible to children.

"Species rarely cultivated outside its native range despite its good adaptability and ornamental appeal. Its name honours the German botanist Nicolas Funck (1816–1896). Taxonomically close to Agave lophanta and frequently confused with it; distinguished by its narrower leaves and more northerly distribution."
