This species was found during the herborizing of the Tehuacan-Cuicatlan valley and described in 1996. 


From Mexico, State of Oaxaca, district of Teotitlan, municipality of Santa Maria Ixcatlan, Rio Seco to Rio Santiago. This is the type location and olnly known location for this species.

According to the publication, the plants grow in tropical caducifolia forest, on rocky slopes shaded and wet in the border of the rio at an altitude of 1250 meters. 

Introduction in culture :

Not yet up to now.


(North hemisphere, France near Paris, in a polycarbonate greenhouse - see the map -)


Life cycle : According to the publication, the plant forms different leaf rosettes according to the season (see link). During the resting months (winter) the small succulent rosette is composed of numerous non-carnivorous leaves. The carnivorous leaves are produced in spring and during all summer. The flowering occurs in december from the winter rosette.


Media : I will use a 100 % mineral media : 2 perlite, 2 vermiculite, 1 small sand (for aquarium), 1 fine white sand, 1 pouzzolane (volcanic lava), 1 aqualit (expansed ceramic for aquarium). The aqualit can be replaced by 1 of pouzzolane. Plants in this media grow slower but have a stronger root system.


Pot : plastic, colour terracotta, diameter 12.5cm, height 12cm.


Cultivation : no data.


Multiplication : no data but the plants could be propagated using non-carnivorous leaves separated from the rosette at the end of winter.

PICTURES: (click to enlarge)

I have no pictures of Pinguicula mirandae to show but you will find below pictures of a species collected by Alfred Lau in Oaxaca, near Santiago Nuyoo, at the Pass. According to the publication, this plant could be close or identical with Pinguicula mirandae. Oliver Gluch ( was the first to succeed in showing that his plant was not identical to P. mirandae, but a new and undescribed butterwort species (see the specific page). All the pictures comes from Oliver Gluch.
