This miniature slipper orchid is one of the rarest species within the genus Phragmipedium, making it highly sought after by collectors. 

• Light: Prefers bright, indirect light to semi-shaded conditions. Avoid direct, harsh sunlight which can scorch its leaves. 
• Temperature: Thrives at intermediate temperatures. Aim for daytime temperatures between 15-26°C (59-79°F) and a crucial drop to cooler nighttime temperatures between 13-18°C (55-65°F) to encourage blooming.
• Humidity: Requires high humidity, ideally around 60-80%. This can be achieved through humidifiers, frequent misting, or growing in a terrarium. Good air circulation is vital to prevent fungal issues in high humidity.
• Watering: like many Phragmipediums it's prefers to have its "feet wet," meaning the potting mix should be kept consistently moist but never waterlogged. 

• Substrate: Use a porous, moisture-retentive, yet free-draining mix. 

Additional Notes

Conservation Status: Given the rarity of many Phrag. species, including some of its close relatives which are critically endangered, P. anguloi is a species of significant conservation concern.
