Trichocereus tulhuayacensis is very rare and could only be found around Huancayo. This is the only San Pedro cactus in nature with a flower other than white. The flower is pink what indicates a natural hybrid of a San pedro with something else.
Description of Trichocereus tulhuayacensis
It gets up to 2 meters tall, has a dark green epidermis and can reach a maximum diameter of 10 to 12 centimeters. It shows a mild reddening around the Areoles, has 7-9 ribs (in most cases 8). The Areoles are 8-10 mm large with V-notches above them. The Diameter of the Areoles is 6-8 mm. The areoles are yellowish felted at first and change their color to a dark gray later on. It has 8 radial Spines (1,5 to 2,5 cm in length) and 3-4 middle spines (up to 8 centimeters) of which one is usually very long. It resembles Trichocereus tarmaensis and is probably related to it. All spines apart from the long middle spine are usually bent down or pointing downwards. The large Spine is usually gray with a brown tip.

I am really happy about those pics because this Trichocereus is really rare. It is very similar to a Cuzcoensis and I don´t think it´s possible to spot this plant at a plant sale. You have to collect it at the original location in Huachac, Peru at 3200 meters. And even if you can, there is a white flowering KK337 and a red flowering KK337. I am not sure how the Sacred Succulents plant will flower but chances are it will flower in white.
