Cereus hildmannianus subsp. uruguayanus

 There is a long list of synonyms…

Cereus hildmannianus subsp. uruguayanus (R. Kiesling) N.P. Taylor is the correct and accepted scientific infraspecific name for this subspecies of Cereus hildmannianus. It was named and first described as such by Nigel Paul Taylor in Cactaceae Consensus Init. in 1998. Cereus hildmannianus was named and first documented by Karl Moritz Schumann in Flora Brasiliensis in 1890. Cereus uruguayanus was named and first documented by Roberto Kiesling in Darwinian in 1982. However, the same species was named and documented as Piptanthocereus uruguayanus by Friedrich Ritter in Kakteen Südamerika in 1979. BUT, somehow it was all screwed up and wasn’t an accepted name… The 2013 version of The Plant List says it was an unresolved infraspecific name but the new Plants of the World Online says it is now accepted. Thanks, Kew!

BUT… Some have this cactus and Acanthocareus tetragonus confused. When it is all said and done, they could be the same species… Well, I now have both and there definitely are differences.

 

Cereus hildmannianus subsp. uruguayanus when I bought it on 1-28-16.

I bought this cactus from Wal-Mart on January 28, 2016. I had been there a few days earlier and noticed they had just got in a shipment of cactus and succulents. They were still wrapped in plastic sleeves and drenched with water. I didn’t have money at the time, so I went back on the 28th to see what they had. Believe it or not, the plants were STILL wrapped in their plastic sleeves and STILL soaked with water.

Most cactus I buy from Wal-Mart are small, but this one measured 6 1/8″ tall x 3 1/2″ wide.

This plant was unlabeled, so instead of trying to figure out what it was, I put photos on a Facebook group for suggestions. One of the members said it was Cereus hildmannianus subsp. uruguayanus and the common name was Fairy Castles. I checked the name out and believe that is correct.

Cereus hildmannianus subsp. uruguayanus ‘Fairy Castles’ on 5-31-17, #339-7. (Notice the baby Walking Stick?).

The ‘Fairy Castles’ did well the first summer but started getting weird over the winter. It was turning yellow and I thought it would soon die. I just noticed the baby Walking Stick in this photo as I was updating this page… 🙂

 

Cereus hildmannianus subsp. uruguayanus ‘Fairy Castles’ on 9-7-17, #371-7.

When I took the above photo I noticed some critters, probably crickets, had been snacking.

According to Plants of the World Online, this subspecies is native to Northeast Argentina, southern Brazil, and Uruguay. Llifle (Encyclopedia of Living Forms) say it occurs only in Uruguay. The species Acanthocereus tetragonus has a much wider range. As far as the cultivar ‘Fairy Castles’ is concerned, its origin is somewhat controversial. Apparently, it was discovered “in cultivation” which means not in the wild, such as in a nursery or garden.

 

Cereus hildmannianus subsp. uruguayanus ‘Fairy Castles’ on 10-17-17, #384-4.

I bought the potted plants inside for the winter on 10-17-17. I took them to the basement first then moved the cactus and succulents upstairs. As you can see, it looks like this plant is barely hanging on. Even though it looks like it does, it did grow. It measured 6 7/8″ tall x 4″ wide when the above photo was taken.

Cereus hildmannianus subsp. uruguayanus on 1-27-18, #407-3.

Well, as you can tell in the above photo, it isn’t dead. It is growing! It has been in my bedroom over the winter and has been looking better. You just have to overlook all the scars from the crickets.

 

Cereus hildmannianus subsp. uruguayanus (Fairy Castles) on 7-30-18, #488-8.

We had a pretty bad Japanese Beetle invasion and I had to move the potted plants to a new location. I put the cactus on the back porch in full sun and most of the other potted plants went on the front porch.

 

Cereus hildmannianus subsp. uruguayanus (Fairy Castles) on 10-10-18, #519-18.

Temperatures started dropping so I decided to move the potted plants inside for the winter. As usual, I measured them and this plant is now 7 1/4″ tall x 4 1/2″ wide. That’s very good! It measured 6 7/8″ tall x 4″ wide last October 17.

I will continue adding photos and information as time goes by.
