Distribution. Brazil

Dr. Rose saw the Loefgren type in the Botanical Garden at Rio de Janeiro and obtained living and herbarium specimens of the plant. Dr. Shafer also obtained living specimens from Loefgren in 1917.

Unfortunately, Loefgren's name was given to another plant by Gurke and for this reason we have renamed it in honor of Dr. Alberto Loefgren (1854-1918), who long studied this genus and published an excellent monograph of it in 1915.

NYBG herbarium had a pressed specimen on file but a search by staff failed to find it.
