Rubus glabratus is a Latin American species of brambles in the Rosaceae. It is native to Central America (Panama, Costa Rica) and South America (Colombia, Ecuador, Bolivia).[ Rydberg, Per Axel. 1913.

Rubus glabratus is a perennial subshrub with stems up to 80 cm (2 2/3 feet) long, with curved prickles. Flowers are rose-colored. Fruit is red.[ Kunth, Karl Sigismund 1824. Nova Genera et Species Plantarum (quarto ed.) 6: 221 description and figure captions in Latin][ Kunth, Karl Sigismund 1824. Nova Genera et Species Plantarum (quarto ed.) 6: 221 full-page line drawing of Rubus glabratus]
The genetics of Rubus is extremely complex, so that it is difficult to decide on which groups should be recognized as species. There are many rare species with limited ranges such as this. Further study is suggested to clarify the taxonomy.[ Flora of North America, Rubus Linnaeus, 1754. Bramble]
