Stenospermation ellipticum Croat & D.C.Bay

• Genus: Stenospermation
• Botanical Background: The species was formally described by aroid specialists Thomas B. Croat and D.C. Bay, expanding the known diversity of Ecuadorian aroids. It is part of ongoing efforts to catalog Araceae species in South America.

• Geographical Range: Endemic to Ecuador; found in moist, montane tropical forests.
• Environment: Thrives in humid, shaded environments typical of cloud forest ecosystems; often growing on forest floors with high organic content and consistent moisture

Leaves

• Foliage is elliptic, moderately sized, and exhibits a glossy green surface
• Smooth texture and a slightly leathery feel

Inflorescence (Spadix & Spathe)

• Modest and not particularly showy
• Spathe is pale to greenish and encloses a cylindrical spadix
• Pollination is presumed to involve small forest insects

Growth Habit

• Terrestrial or occasionally epiphytic species
• Has a rhizomatous base and tends to grow upright in low light understory conditions

Light Requirements

• Prefers bright, indirect light
• Direct sun should be avoided, especially in cultivation outside its native habitat

Watering & Humidity

• Requires consistently moist soil and high humidity
• Allow the top layer of soil to dry slightly between waterings but never fully dry out

Soil & Potting Mix

• Well-draining, chunky aroid mix with components like orchid bark, sphagnum moss, and perlite
• Breathable container with drainage holes is ideal

Temperature & Fertilizer

• Thrives in temperatures between 65–80°F (18–27°C)
• Feed monthly during the growing season with a balanced, diluted fertilizer

Division

• Propagation is typically done via rhizome division

Stem Cuttings (if applicable)

• Stem cuttings with visible nodes

Seeds

• Seed propagation is rare and requires fresh seeds with warm, humid germination conditions

Typical Issues

• Spider mites, mealybugs
• Overwatering can lead to root rot
• Ensure good air circulation and avoid soggy media

Treatment Recommendations

• Treat pests with neem oil or insecticidal soap
• For root rot, remove affected roots and repot in fresh, well-draining mix

• Contributes to the rich biodiversity of Ecuador’s Andean cloud forests and may play a role in microhabitat ecology

• Valued for its clean, elliptical foliage and compact form, it is sought after by collectors of rare and unusual tropical aroids

Wild Population Status

• Endemic species with a limited range
• May face habitat-related threats. Specific conservation assessments are limited, but habitat protection in Ecuador is crucial

Market Availability

• Rare in cultivation
• not commonly available in the horticultural trade
  
• May be found through specialty collectors or botanical institutions
