Type.

“Brasilien”.

The Glaziou 6747 specimen from Brazil has three duplicates, of which B10 0243260 is the lectotype, designated as “type” by Smith and Downs (1968). The isolectotypes deposited in P and K are: P01679919, K000587085. The label of the sheet at P gives the origin of the collection as Brazil, Rio de Janeiro, Itatiaia , January 22, 1873. In the K isolectotype, there is no information on locality or date. The information given is the collector and the respective collection number, the origin as Rio de Janeiro, and the date as February 1874. The later date of the Kew specimen might signify when the specimen was received at K as a duplicate from P. However, there is no doubt that the three exsiccates are from the Glaziou 6747 collection .
