Anthurium gomesianum Nadruz

• Genus: Anthurium
• Botanical Background: First described by C. Nádruz in Aroideana 29: 98 (2006); the holotype was collected near Santa Tereza, Espírito Santo, at ca. 250 m elevation.

• Geographical Range: Endemic to the municipality of Santa Tereza in Espírito Santo, Brazil.
• Environment: Occurs as a rupicolous or terrestrial herb in submontane to montane Atlantic Forest, favoring humid, shady rock outcrops and tree trunks.

Leaves

• Greenish, discolorous, chartaceous, linear‑lanceolate blades (19–37.3 × 1.6–3.9 cm)
• Acute base and rostrate‑apiculate apex

Inflorescence (Spadix & Spathe)

• Peduncle erect, 12.5–25.5 × 0.2–0.26 cm; spathe lanceolate, greenish‑vinaceous
• Spadix sessile, castaneous to brownish
• Flowers protogynous, arranged in a spiral; tepals rugose externally
  
• Attract primarily small dipterans (flies), euglossine bees, and Curculionid beetles such as Cyclanthura weevils, which effect pollen transfer

Growth Habit

• Herbaceous with erect stem
• Extremely short internodes, persistent cataphylls
• Epiphytic or rupicolous, lacking tubers but sometimes with short rhizome extensions

Light Requirements

• Bright, indirect light 
• Avoid direct sun
• Insufficient light may inhibit spathe development
  

Watering & Humidity

• Maintain consistent moisture, do not allow substrate to dry out completely
• High ambient humidity (>60 %) is beneficial

Soil & Potting Mix

• A well-draining, airy mix (peat‑based substrate with perlite or orchid bark)
• Ensure good drainage with pot shards or large bark pieces
  

Temperature & Fertilizer

• Optimal range 18–28 °C; minimum 15.5 °C in winter
• Balanced, water‑soluble fertilizer every 2–4 weeks during active growth

Division & Cuttings

• Rhizome division or stem‑node cuttings in moist soilless medium
• Maintain high humidity until new roots form

Seeds

Collect ripe berries. sow fresh seeds on a sterile, moist medium (e.g., sphagnum moss or peat mix)
• Germination in warm (21–26 °C), shaded conditions; viability declines rapidly if dry

Typical Issues

• Anthracnose and bacterial blight (water‑soaked lesions)
• Root rot from overwatering
• Spider mites, mealybugs, scale insects, thrips
  
• Fungus gnats in overly moist media

Treatment Recommendations

• Neem oil or insecticidal soap sprays
• Physical removal of scale/mealybugs
• Systemic bactericides/fungicides for blights
• Trim and repot to fresh mix for root rot

• Endemic with a highly restricted range
• Predicted as threatened by extinction‑risk models

• Prized for its elegant, narrow foliage and subtle vinaceous spathe

• Rarity enhances its appeal in specialist collections

  
  

Wild Population Status

• Predicted to be threatened (high confidence) by Angiosperm Extinction Risk Predictions

Market Availability

• Not widely available commercially
• Occasionally offered through specialist aroid nurseries and collector networks
