ORIGIN AND
HISTORY :
Alfred
Lau, the famous Botanist found this species around 1987 near the village of
Santiago Nuyoo in Oaxaca. He sent seeds to various growers in Europe and the
plants were grown under the publication under the name Pinguicula
“Santiago Nuyoo Pass”.
This
village is not far from Santa Maria Yucuhiti where Alfred Lau found also another
population of plants related to Pinguicula moranensis and still grown in Europe under the name Pinguicula
“Santa Maria Yucuhiti”.
Map
/ LOCALISATION :
From
Mexico, Oaxaca, municipality of Santo Tomas Ocotepec, near La Cueva de la Hoya
at +/- 10 km to NE of Santiago Nuyoo. This is the type location and olnly
known location for this species.

HABITAT:
On
calcareous rocks in bosque mesofilo montano with Chirantodedron,
Cercocarpus, Buddleia and Quercus, at altitudes of 2400 m.

stations).
Introduction
in culture :
From
the seeds of Alfred Lau. The plant is still very rare in culture.
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 flowering occurs from winter rosette. The life
cycle of the plant is probably similar in it's native habitat.
Media
: I use today (arrival of my
clone in late 2002) 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. Johan
van Marm told me that he had better results on acidic media.
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 25°C but may reach 35°C
when the sun is shining on the greenhouse in spite of the use of shading
covers. Night temperatures are around 20°C. During resting period : day/night
over freezing point. Lower temperature observed : - 4°C. I use an
electronic petroleum heater to provide heat.
Flowering
period :
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 including the white base
as the plantlets will sprout from this area. I don't know yet if it is
possible to have seeds in culture.

Typical
"Bosque mesofilo de montana"
It
is located in ravines and in an area protected from wind and sun, which favours
a high air humidity.
