Cyrtosperma gressittiorum A.Hay

• Genus: Cyrtosperma
• Botanical Background:  Described by A.Hay, the species honors the contributions of the Gressitt family in entomology and natural history. Its initial documentation has led to ongoing interest among aroid researchers.

• Geographical Range: Native to tropical areas in Southeast Asia and nearby regions, where it occurs in moist, shaded forest environments.
• Environment:  Naturally thrives in high humidity and warm climates. IPrefers rich, well-draining soils found in tropical lowland rainforests with dappled sunlight.

Leaves

• Large, heart-shaped with a glossy, dark green surface
• Prominent venation that gives a dramatic visual appeal

Inflorescence (Spadix & Spathe)

• Slender spadix surrounded by a modestly colored spathe, usually in tones of greenish or cream, with minimal scent
• The structure plays a role in specialized pollination mechanisms

Growth Habit

• Terrestrial, from a robust rhizome, often forming clumps that can spread gradually in suitable conditions
• Well-suited for both ground planting and large container cultivation

Light Requirements

• Bright, indirect light

• Direct sunlight may scorch the leaves, while low light can slow growth

Watering & Humidity

• Consistent moisture and high humidity
• Water regularly to keep the soil evenly moist but avoid waterlogging to prevent root rot

Soil & Potting Mix

• A well-draining, organic-rich potting mix (peat, perlite, and compost)
• Maintain proper moisture and aeration

Temperature & Fertilizer

• Thrives in between 65°F and 85°F
• Balanced liquid fertilizer applied monthly during the growing season supports healthy growth

Division and Cuttings

• Division of rhizomes, carefully separating mature clumps can yield viable new plants

Seeds

• Less common due to slow germination rates and variable viability, making vegetative methods more popular among growers

Typical Issues

• Pests like aphids and spider mites
• Overly moist conditions can also lead to fungal issues such as root rot

Treatment Recommendations

• Regular inspection and treat pests with organic insecticidal soap
• Ensure proper drainage and moderate watering practices to prevent fungal infections

• Celebrated for unique inflorescence and robust leaf structure

• Sparked interest in both botanical research and tropical horticulture for its discovery and documentation

• Prize for rare appearance and ornamental foliage
• Desirable specimen in tropical plant collections due to its unusual structure and cultivation challenges

Wild Population Status

• While not extensively studied in the wild, its limited distribution suggests that wild populations are not widespread. Ongoing research is needed to assess its conservation status

Market Availability

• Considered rare in cultivation
• Often sought after by collectors and specialists in tropical aroids, with availability limited to select nurseries
