Etymology : Pinguicula takakii have been named in honour of the Biologist Francisco Takaki, who was the first collector of this species. This person is well known among Mexican Botanists for his contribution on the mapping of the vegetation of the country.

Pedicelli 1 – 5, , atrorubri, 25 – 26 mm longi, uniflori. Flores 6 – 12 (14) mm longi (calcare incluso). Calyx atroruber, bilabiatus; labium superum usque ad 2/3 – ¾ longitudinis trilobatus; lobis oblongo-triangularibus, obtusis vel acutis , 0.8 – 1.4 mm longis, 0.4 – 0.7 mm latis; labium inferum bilobatum usque ad ¼ - ½ longitudinis, lobis triangularibus, acutis, 0.3 -0.7 mm longis, 0.3 – 0.5 mm latis. Corolla subisoloba, violacea, tubi parte infera et calcare luteis, faucibus luteis sed parte infera lineis atrorubris +/- sex, lobi breviter spathulati vel obovati usque ad subquadrati, apice rotundati vel truncati, breviter emarginati vel leviter undulati, 2 – 3 mm longi et lati; palatum semilentiforme, 0.6 – 1.3 mm longum, 0.6 – 2 mm latum, leviter emarginatum, luteum, dense pilosum, pilis multicellularibus claviformibus; tubus subcylindricus, 4 – 5 mm longus, 3 - 4 mm latus, intus pilis multicellularibus subulatis, aliquis ramosis; calcar cylindricum, 2 – 3.5 mm longum, 0.8 – 1 mm latum, angulum obtusum formans.

ORIGIN AND HISTORY :

Pinguicula takaki was discovered by the Biologist F. Takaki and is very similar with Pinguicula lilacina Schlecht. & Cham. and with Pinguicula sharpii Casper and Kondo, but can be distinguished by the leaves (5 to 16 mm wide) shortly spatulate and obovate with the basis abruptly cuneiform until a little more of the half of the leaf, that are a little more smaller than the rounded ovate leaves or obovate with a cuniform basis ( (15) 20 – 35 (45) mm wide) of Pinguicula lilacina and the broad obovate leaves with a cuneiform basis (14 – 18.5 mm) of Pinguicula sharpii. 

 

The pedicel and the calyx coloured purple distinguish it from the others species by the fact that these parts are yellow or green-yellowish on the other species. The flowers are shorter than the flowers of P. lilacina or similar or sometimes larger than the flowers of Pinguicula sharpii.  

 

The hairs inside the corolla are also different : Pinguicula takakii and Pinguicula sharpii have multicellular hairs claviform on the palate, shorter and subulate in the tube, where few have lateral extensions, for Pinguicula lilacina the hairs of the palate are wider.

And its habitat is also notably different from the others because Pinguicula lilacina and Pinguicula sharpii grows on rocks, on edges or slopes of Oaks woods, Pine-Oaks woods or mesofil mountain woods with a subhumid climat or humid, while P. takakii grows on gypsum soil with Selaginella sp. and P. gypsicola Brandegee on dry hills with matorral desertico rosetofilo of Hetchia glomerata, Agave striata and Dasylirion longissum.

HABITAT:         

Pinguicula takakii can be found on gypsum hills with matorral desertico rosetofilo composed of Hechtia sp., Agave striata, Dasylirion longissum and Dodonea viscosa or with matorral rosetofilo of Hetchia glomerata, Agave striata, Dasylirion longissimum at altitude of 1350 - 1400m.

Introduction in culture :

Not yet in Europe but in Mexico now since 2003

CULTURE AND MULTIPLICATION : 

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

Life cycle : As this species can be found growing close to Pinguicula gypsicola in habitat, I would write that this species have the same kind of weather. As an annual species, the plant will only form an homophyllous leaf rosette and doesn't form a resting rosette composed of numerous non-carnivorous leaves as for Pinguicula gypsicola. The dry season will be passed by this species under a seed stage.

 

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. If I get some, I will also add some blocs of gypsum in this media.

 

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

 

Cultivation : I don't feel that this species will be harder to grow than P. sharpii. I will also use my usual gowing method as for nearly all the Mexican Pinguicula with the exception that I will not let the media drying. Using this way, the flowering stage, occuring at the end of the life of this plant (annual species), will offer more chance to produce more seeds.   

 

Multiplication : This species is annual so seeds will be the easiest and maybe the only way to multiplicate it. I don't know if the flowers can be self-pollinated (I think so as for P. sharpii). I think also that the leaf cutting won't work (as for P. sharpii).
