Taxonomy & Classification

Common Names by Region

Etymology

The genus name Oreopanax comes from Greek oros (mountain) + Panax (the ginseng genus), referring to the mountain-dwelling nature of these trees and their relationship to ginseng in the same family (Araliaceae). The species epithet xalapensis refers to Xalapa (also spelled Jalapa), a city in Veracruz, Mexico, near where the species was first scientifically described.

The common name "Lorito" (little parrot) refers to the leaf shape, which resembles a parrot's foot. Alternative names like "Mano de León" (lion's hand) and "Mano de Tigre" (tiger's hand) similarly refer to the distinctive palmate leaves.

Family Relationships

The Araliaceae (ginseng family) includes about 1,500 species worldwide, many of tropical and montane distribution. Notable relatives include:

• Panax ginseng - Asian ginseng, medicinal plant
• Hedera helix - English ivy
• Schefflera species - Umbrella trees, popular houseplants
• Aralia species - North American aralias

Physical Description

Tree Form

Lorito is a small to medium evergreen tree or large shrub typically reaching 8-15 meters in height with a trunk diameter of 15-30 cm. The growth form is characteristic:

• Trunk: Usually single-stemmed but can be multi-trunked; relatively slender
• Bark: Smooth, gray to gray-brown, with light lenticels
• Crown: Rounded to irregular, relatively open; branches spreading
• Growth Pattern: Evergreen; maintains foliage year-round
• Form: Often somewhat irregular or asymmetric, lending it a distinctive character

Leaves

Detail: The leaves are the tree's most distinctive feature. Large and deeply palmately lobed (5-9 lobes), they resemble an outstretched hand or parrot's foot—hence the common names. Each lobe is 8-15 cm long, elliptic to lanceolate, with toothed margins. The upper surface is dark green and somewhat glossy, while the lower surface is paler and may have a slightly fuzzy texture when young. Leaves are borne on long petioles (leaf stalks) 10-20 cm long, allowing them to move gracefully in the wind. The leaves tend to cluster at the tips of branches, creating an attractive layered appearance.

Juvenile leaves may have fewer lobes and a different shape than mature leaves, a phenomenon common in the Araliaceae family.

Flowers

Description: Flowers are small and inconspicuous individually but produced in compound terminal inflorescences (umbels or panicles) 10-20 cm across at the ends of branches. Each flower is small (3-5 mm), greenish-white to cream in color, with 5 petals and 5 stamens. The flowers have a subtle, slightly sweet fragrance and attract various insects. While not showy, the flowering period adds interest with the clusters of pale flowers contrasting against the dark green foliage.

Fruit & Seeds

• Type: Small berry (drupe)
• Size: 4-6 mm diameter
• Color: Green when young, ripening to purple-black
• Form: Spherical, clustered in groups
• Seeds: 2-5 small seeds per fruit
• Season: June-August
• Wildlife: Important food for montane birds

Habitat & Ecology

Ecological Role

Lorito plays several important roles in cloud forest ecosystems:

1. Mid-Canopy Layer: Forms part of the understory to mid-canopy in mature forests
2. Wildlife Food: Berries are important food source for montane birds
3. Pioneer Species: Can colonize disturbed areas, helping in forest regeneration
4. Erosion Control: Root system helps stabilize slopes in steep terrain
5. Biodiversity Support: Provides habitat and food for various insects and birds

Wildlife Associations

Forest Dynamics

• Succession: Can establish in disturbed areas and forest gaps; grows faster than some other cloud forest species
• Shade Tolerance: Moderately shade-tolerant when young; needs more light as it grows
• Longevity: Moderate; individuals typically live 50-80 years
• Fire Sensitivity: Susceptible to fire like most cloud forest species
