ORIGIN AND HISTORY :

- more soon - 

Pinguicula lilacina Schlecht., Pinguicula sharpii Casper and Kondo& Cham., Pinguicula takakii and are very similar , but can be distinguished by the leaves : 

Pinguicula takakii : (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. 

 

For Pinguicula takakii, the pedicel and the calyx coloured in 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 their habitat is also notably different : 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.

Map / LOCALISATION : 

 

This species is widespread all over mesoamerica (yellow area), some of the locations found  in  :

 

Mexico, state of Oaxaca (Santa María Chimalapa, Santiago Lachiguiri), state of Queretaro (Jalpan, Landa, Arroyo Seco), state of San Luis Potosi (Aquismon), state of Veracruz (Totutla, Xalapa, Dos Ríos) according to Mexu. 

Casper wrote in his monography other locations : State of Oaxaca (Cordillera), state of Guerrero (Chilpancingo), state of Sinaloa (Capadero, Sierra Tacuichamona), stae of Chihuahua (San Ignacio, San Javier), state of Nueva Leon (Dulces Nombres, near Monterrey), state of Tamaulipas (San Juan), stae of Vera cruz (Zacuapan, Barranca de Jenampe)...

 

and in Guatemala and in Honduras (?)

 

HABITAT:         

Pinguicula lilacina grows on rocks, on edges or slopes of Oaks woods, Pine-Oaks woods or mesofil mountain woods with a subhumid climat or humid at altitudes from 700 to 2400m.  

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 : Little is know about this species. 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 many Pinguicula. 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. 

 

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).
