Trichocereus pallarensis, also known as Echinopsis pallarensis, is an obscure species from North Peru that was discovered and described by Friedrich Ritter. It belongs into the same context that Trichocereus santaensis / Echinopsis santaensis belongs to.
Trichocereus pallarensis is a species that was described by Friedrich Ritter and listed in his WINTER catalogs starting in 1961! I do have most of the old Winter catalogs, but I unfortunately not the ones after 1960. But that´s not a problem as I have a whole lot of other information about Trichocereus pallarensis.
Ritter wrote about this species numerous times. He basically called this plant a “variety of Trichocereus pachanoi”, but described it as a new species just in case. Back then, it was common that botanists or taxonomists wrote new descriptions only based on minor differences, that would only be seen as a regional form by today´s standards.
Trichocereus pallarensis has 3 – 6 radial spines (15 – 50 mm long). Those are brown or honey colored and relatively thin compared with the ones on Trichocereus peruvianus and Trichocereus pachanoi. The middle spines are often missing or there is only one very strong and long middle spine. It is very similar to Tr. pachanoi in regards to the spination and most of the spines are only few millimeters long. The areoles are often very small and those packed areoles usually tend to miss the one middle spine as well.
Flowers of Trichocereus pallarensis:
Friedrich Ritter was not able to get a good description of the flower and I am working on one myself. The plant is very rare and if you happen to have a flowering sized one, please let me know so we can improve the flower description. With that said, it comes from the Pachanoi group and is probably almost identical to the one of Tr. pachanoi. The flower is definitely white, but I´d love to measure it some more.
Fruit of Echinopsis pallarensis:
The fruit of Trichocereus pallarensis is 5 cm long and 4 cm thick. Covered with GRAY wool.
Seeds: The seeds of Trichocereus pallarensis are identical to the ones on other Tr. pachanoi types.
Origin/ Type locality of T.pallarensis:
Trichocereus pallarensis grows in Llancora, near Cajamarca. Near Pallar (that´s where the name comes from) and east of the cordillera Blanca. Department Ancash at 2.500 – 3.000 meters altitude.
