TAXONOMY:

Family : Lentibulariaceae

Genus : Pinguicula

Name : not yet published, the plant can be found under the names Pinguicula moranensis 'Rio Grivalva' or Pinguicula moranensis 'Rio Grijalva', Pinguicula moranensis 'Grivalva' or Pinguicula 'Grijalva'

 

Sub-classification (Casper) : link

Publication : no publication

DESCRIPTION :

- soon - 

ORIGIN AND HISTORY :

- No data -

This plant is labelled "Rio Grijalva". As the Rio Grijalva runs into the Canyon of Sumidero (Canon del Sumidero) in Oaxaca and as plants labelled Sumidero 1 and Sumidero 2 are in culture, it is possible that the collector of these  two plants is the collector of the mysterious plant "Rio Grijalva". There is a town named Grijalva in Chiapas too

 

Many hypothesis isn't it ? 

Map / LOCALISATION : 

 

In Chiapas, there is a river called Grijalva (Rio Grijalva). This river pass thought a big canyon called "Canon del Sumidero". There is a town named Grijalva in Chiapas too

HABITAT:

Introduction in culture :

I got my clone from Stan Lampard's collection (UK).  

CULTURE AND MULTIPLICATION : 

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

 

Life cycle : The life cycle observed in culture for this Pinguicula consists of two seasons, one wet and the other dry (see link). The plant forms different leaf rosettes according to the season. 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 life cycle of the plant is probably similar in it's native habitat.

 

Media : I 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 : I think that a slightly airy situation inside the greenhouse is important to avoid air stagnation. For this reason, I use a fan 24h/24h all the year round.

Watering is very important : from May to September (summer). I let the media drying slightly between two watering. I use rain water poured on the top of the pot taking care not to wet the rosette.  From October to April, It is important to let the media drying completely (no watering) but with an atmospheric humidity of about 80%. 

The mentioned months are indicative and can change according to your own growing conditions. In fact, when this Pinguicula begins to produce its non-carnivorous leaves, you have to stop watering and let the pot drying out completely. Inversely, when the plant begins to produce in early spring its carnivorous leaves, you have to progressively start watering again the pot.

Temperatures : during growth period, day temperatures are about 25C but may reach 35C when the sun is shining on the greenhouse in spite of the use of shading covers. Night temperatures are around 20C. During resting period : day/night over freezing point. Lower temperature observed : - 4C. I use an electronic petroleum heater to provide heat.  

Flowering period : not yet observed

 

Multiplication : The plants can be propagated easily using non-carnivorous leaves separated from the rosette at the end of winter. You only have to carefully tear out the totality of the leaf particularly with it's white base as the new plantlets will sprout from this area. Don't try with the summer leaves, it is harder.
