DESCRIPTION :

 

Herba perennis. Folia radicalia rosulata integerrima biformia; rosula hiemis hypogaea 5 - 15 mm diametro bulbiformis ex foliis numerosis (6 - 30) composita, foliis squamiformibus obtrullatis vel ellipticis apice obtusis mucronatis glabriusculis 3 - 10 mm longis, 1.5 - 4 mm latis; rosula aestatis (3) 4 - 8 foliis erectis composita, foliis lineari-lanceolatis, proximaliter distaliterque gradatim attenuatis, superne glandulis sessilibus dense vestitis et glandulis stipitatis modice dense vestitis, (60) 80 - 260 mm longis, 3 - 8.5 mm latis margine valde revolutis. Pedunculi 1 - 3, erecti, glandulis stipitatis obsiti, 60 - 150 mm alti, uniflori. Flores 20 - 35 mm longi (clacari incluso). Calyx bilabiatus extus glandulis stipitatis obsitus; labio supero usque ad basim trilobo, lobis usque ad 1/4 - 1/2 longitudinis divisis, lanceolatis vel triangulatis. Corolla bilabiata rubro-purpurea extus glandulis stipitatis dispersis obsita, lobis oblongis vel anguste oblongis, obtusis vel rotundatis 5 - 8 mm longis, 3 - 6 mm latis. Tubus longe infundibuliformis, albus vel ex purpureo albus 7 - 10 mm longs, intus pilosus basim tubi versus pilis brevioribus. Calcar 7 - 16 mm longum. Stamina 2 - 2.5 mm longa; pollen (4) 5 (6) - colporatum. Ovarium subglobosum glandulis stipitatis dispersis obsitum. Stigma violaceum bilabiatum; labio infero suborbiculato dentato.

ORIGIN AND HISTORY :

Explorations in valleys in cloud forest in the border of Queretaro and San Luis Potosi states revealed a Pinguicula with a bilabiate corolla with long-infundibuliform tube, as long as or shorter than the spur, placed in subgenus Pinguicula, section longitibus and described as a new species under the name Pinguicula calderoniae. 

This taxon is crealy differentiated from other members of this group by its long lanceolate-linear summer leaves ((60) 80 - 260 mm !), which is unique in the section. 

Map / LOCALISATION : 

 

Two locations are noted in the publication : 

 

- From Mexico, Queretaro. Municipio de Landa, extrem north of the Llano Chiquito.

HABITAT:         

On calcareous rocks in the cloud forest (bosque mesofil de montana). Plants grow at altitude of 2200 to 2300m. According to the publication, Pinguicula calderoniae grows on wet calcium carbonate concretions, on vertical calcareous walls, in limestone cracks.

TEMPERATURE and PRECIPITATIONS :

 

Click on the graph to enlarge and see the graph of normal precipitation and normal average temperatures. Normal values are 30-year averages for the period 1961 to 1990. The weather stations are grouped by region (see map of weather stations).

 

Introduction in culture :

Except in a Mexican collection, this species seems to have been introduced in-vitro in 2009 in Europe. 

CULTURE AND MULTIPLICATION : 

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

Life cycle : Flowering in June in habitat with young summer leaves and last winter leaves. In culture (in Mexico), the summer rosette last until October and the winter rosette is produced in november. The compact winter rosette remains until May of the following year. 

 

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. I will work as for all other Mexican Pinguicula.

 

Multiplication : no data. The plants should 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 including the white base as the plantlets will sprout from this area.

tufa : calcium carbonate

A chemical sedimentary rock composed of calcium carbonate, formed by evaporation as a surficial, spongy, porous, semifriable incrustation around the mouth of a hot or cold spring or seep, or along a stream carrying calcium carbonate in solution, and exceptionally as a thick, bulbous, concretionary or compact deposit in a lake or along its shore. It may also be precipitated by algae or bacteria.

Pinguicula calderoniae in habitat

by Radek KASTNER.
 

Pinguicula calderionae can be found growing with P. martinezii and P. moranensis. Plants grow on very tall vertical rocky cliffs/mountains.
Sites of these three species are about 20 km from city of Xilitla, San Luis Potosí state, Mexico in really steep mountains covered by really nice and mystic misty forest on the top.
Road from Xilitla to La Trinidad is a very bad dirty road with many holes and rocks only.
Between Xilitla and La Trinidad are another two villages in mountains valleys. The way to Llano Conecho is very demanding and it has to be crossed 3 mountain crests.
La Trinidad is an Eco Preserve, you have to pay money here to cross "borderline".
Between La Trinidad and Llano Conecho is altitudinal difference another 150-200 m (???).

The first location where P. calderoniae can be found. There are two different sites near to/or on the Llano Conecho. This location may have been visited for the first time by Europeans during our expedition .

Plants grow very high, most of them are inaccessible, common plants together with butterworts were there Agave stricta.

Leaves are long and very narrow and hang down, plants grow on the rock crevices with hidden bulbs, colour of the leaves differs from green to bright reddish.

Normal plant has only a few leaves (from 3 to 5 at maximum!), if you see more leaves on a pictures, there are always more plants at the same place !

This picture is not sharp enough, but plants were too far - it was interesting, that some of plants hang vertically down from overhanging cliff...
