Commonly known as the Mountain Date palm, naturally found in the forests of Southeast Asia and India. A slow growing, small to medium sized palm similar to roebelenii, but with more plumose fronds. Solitary palms of this type are said to resemble miniature P. canariensis and are reported to tolerate hard frosts.

The species is named after João de Loureiro; it was originally written by Kunth as "loureirii", but this is an error to be corrected to loureiroi under the provisions of the ICBN, so look for this one to be changin names sometime in the future. We had a handful of these growing in one gallon pots, but like many others they fell victim to the weeds..
