Abstract
IN a footnote in NATURE (vol. xlv. p. 10) it is stated that βThe two highest-known species of Rubus are pinnatus and rigidus, at 5000β6000 feet.β This is hardly correct, unless it is intended to refer to African species only. In South America, R. megallococcus, R. boliviensis, R. bogotensis, and R. roseus occur at 8000 feet, and R. rusbyi at 10,000. In Colorado I have found R. strigosus above 10,000 feet (see Bull. Torrey Bot. Club, 1890, p. 10; 1891, p. 169). In the Indian region, R. ellipticus goes to 7000, R. lasiocarpus to 8000, and R. biflorus and R. rosifolius to 10,000 feet.
